What Are Critical Thinking Skills and Why Are They Important?
Learn what critical thinking skills are, why they’re important, and how to develop and apply them in your workplace and everyday life.
We often use critical thinking skills without even realizing it. When you make a decision, such as which cereal to eat for breakfast, you're using critical thinking to determine the best option for you that day.
Critical thinking is like a muscle that can be exercised and built over time. It is a skill that can help propel your career to new heights. You'll be able to solve workplace issues, use trial and error to troubleshoot ideas, and more.
We'll take you through what it is and some examples so you can begin your journey in mastering this skill.
What is critical thinking?
Critical thinking is the ability to interpret, evaluate, and analyze facts and information that are available, to form a judgment or decide if something is right or wrong.
More than just being curious about the world around you, critical thinkers make connections between logical ideas to see the bigger picture. Building your critical thinking skills means being able to advocate your ideas and opinions, present them in a logical fashion, and make decisions for improvement.
Why is critical thinking important?
Critical thinking is useful in many areas of your life, including your career. It makes you a well-rounded individual, one who has looked at all of their options and possible solutions before making a choice.
According to the University of the People in California, having critical thinking skills is important because they are [ 1 ]:
Crucial for the economy
Essential for improving language and presentation skills
Very helpful in promoting creativity
Important for self-reflection
The basis of science and democracy
Critical thinking skills are used every day in a myriad of ways and can be applied to situations such as a CEO approaching a group project or a nurse deciding in which order to treat their patients.
Examples of common critical thinking skills
Critical thinking skills differ from individual to individual and are utilized in various ways. Examples of common critical thinking skills include:
Identification of biases: Identifying biases means knowing there are certain people or things that may have an unfair prejudice or influence on the situation at hand. Pointing out these biases helps to remove them from contention when it comes to solving the problem and allows you to see things from a different perspective.
Research: Researching details and facts allows you to be prepared when presenting your information to people. You’ll know exactly what you’re talking about due to the time you’ve spent with the subject material, and you’ll be well-spoken and know what questions to ask to gain more knowledge. When researching, always use credible sources and factual information.
Open-mindedness: Being open-minded when having a conversation or participating in a group activity is crucial to success. Dismissing someone else’s ideas before you’ve heard them will inhibit you from progressing to a solution, and will often create animosity. If you truly want to solve a problem, you need to be willing to hear everyone’s opinions and ideas if you want them to hear yours.
Analysis: Analyzing your research will lead to you having a better understanding of the things you’ve heard and read. As a true critical thinker, you’ll want to seek out the truth and get to the source of issues. It’s important to avoid taking things at face value and always dig deeper.
Problem-solving: Problem-solving is perhaps the most important skill that critical thinkers can possess. The ability to solve issues and bounce back from conflict is what helps you succeed, be a leader, and effect change. One way to properly solve problems is to first recognize there’s a problem that needs solving. By determining the issue at hand, you can then analyze it and come up with several potential solutions.
How to develop critical thinking skills
You can develop critical thinking skills every day if you approach problems in a logical manner. Here are a few ways you can start your path to improvement:
1. Ask questions.
Be inquisitive about everything. Maintain a neutral perspective and develop a natural curiosity, so you can ask questions that develop your understanding of the situation or task at hand. The more details, facts, and information you have, the better informed you are to make decisions.
2. Practice active listening.
Utilize active listening techniques, which are founded in empathy, to really listen to what the other person is saying. Critical thinking, in part, is the cognitive process of reading the situation: the words coming out of their mouth, their body language, their reactions to your own words. Then, you might paraphrase to clarify what they're saying, so both of you agree you're on the same page.
3. Develop your logic and reasoning.
This is perhaps a more abstract task that requires practice and long-term development. However, think of a schoolteacher assessing the classroom to determine how to energize the lesson. There's options such as playing a game, watching a video, or challenging the students with a reward system. Using logic, you might decide that the reward system will take up too much time and is not an immediate fix. A video is not exactly relevant at this time. So, the teacher decides to play a simple word association game.
Scenarios like this happen every day, so next time, you can be more aware of what will work and what won't. Over time, developing your logic and reasoning will strengthen your critical thinking skills.

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.
Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.
In academic writing , critical thinking can help you to determine whether a source:
- Is free from research bias
- Provides evidence to support its research findings
- Considers alternative viewpoints
Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.
Prevent plagiarism. Run a free check.
Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.
Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.
However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.
You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.
However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.
You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.
There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.
However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.
When encountering information, ask:
- Who is the author? Are they an expert in their field?
- What do they say? Is their argument clear? Can you summarize it?
- When did they say this? Is the source current?
- Where is the information published? Is it an academic article? Is it peer-reviewed ?
- Why did the author publish it? What is their motivation?
- How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?
Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:
- Am I only considering evidence that supports my preconceptions?
- Is my argument expressed clearly and backed up with credible sources?
- Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.
Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.
Critical thinking skills include the ability to:
You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.
Ask questions such as:
- Who is the author? Are they an expert?
- How do they make their argument? Is it backed up by evidence?
A credible source should pass the CRAAP test and follow these guidelines:
- The information should be up to date and current.
- The author and publication should be a trusted authority on the subject you are researching.
- The sources the author cited should be easy to find, clear, and unbiased.
- For a web source, the URL and layout should signify that it is trustworthy.
Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.
Being information literate means that you:
- Know how to find credible sources
- Use relevant sources to inform your research
- Understand what constitutes plagiarism
- Know how to cite your sources correctly
Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.
Although selective recall is a component of confirmation bias, it should not be confused with recall bias.
On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

Critical thinking refers to the ability to analyze information objectively and make a reasoned judgment. It involves the evaluation of sources, such as data, facts, observable phenomena, and research findings.
Good critical thinkers can draw reasonable conclusions from a set of information, and discriminate between useful and less useful details to solve problems or make decisions. Employers prioritize the ability to think critically—find out why, plus see how you can demonstrate that you have this ability throughout the job application process.
Why Do Employers Value Critical Thinking Skills?
Employers want job candidates who can evaluate a situation using logical thought and offer the best solution.
Someone with critical thinking skills can be trusted to make decisions independently, and will not need constant handholding.
Hiring a critical thinker means that micromanaging won't be required. Critical thinking abilities are among the most sought-after skills in almost every industry and workplace. You can demonstrate critical thinking by using related keywords in your resume and cover letter, and during your interview.
Examples of Critical Thinking
The circumstances that demand critical thinking vary from industry to industry. Some examples include:
- A triage nurse analyzes the cases at hand and decides the order by which the patients should be treated.
- A plumber evaluates the materials that would best suit a particular job.
- An attorney reviews evidence and devises a strategy to win a case or to decide whether to settle out of court.
- A manager analyzes customer feedback forms and uses this information to develop a customer service training session for employees.
Promote Your Skills in Your Job Search
If critical thinking is a key phrase in the job listings you are applying for, be sure to emphasize your critical thinking skills throughout your job search.
Add Keywords to Your Resume
You can use critical thinking keywords (analytical, problem solving, creativity, etc.) in your resume. When describing your work history , include top critical thinking skills that accurately describe you. You can also include them in your resume summary , if you have one.
For example, your summary might read, “Marketing Associate with five years of experience in project management. Skilled in conducting thorough market research and competitor analysis to assess market trends and client needs, and to develop appropriate acquisition tactics.”
Mention Skills in Your Cover Letter
Include these critical thinking skills in your cover letter. In the body of your letter, mention one or two of these skills, and give specific examples of times when you have demonstrated them at work. Think about times when you had to analyze or evaluate materials to solve a problem.
Show the Interviewer Your Skills
You can use these skill words in an interview. Discuss a time when you were faced with a particular problem or challenge at work and explain how you applied critical thinking to solve it.
Some interviewers will give you a hypothetical scenario or problem, and ask you to use critical thinking skills to solve it. In this case, explain your thought process thoroughly to the interviewer. He or she is typically more focused on how you arrive at your solution rather than the solution itself. The interviewer wants to see you analyze and evaluate (key parts of critical thinking) the given scenario or problem.
Of course, each job will require different skills and experiences, so make sure you read the job description carefully and focus on the skills listed by the employer.
Top Critical Thinking Skills
Keep these in-demand critical thinking skills in mind as you update your resume and write your cover letter. As you've seen, you can also emphasize them at other points throughout the application process, such as your interview.
Part of critical thinking is the ability to carefully examine something, whether it is a problem, a set of data, or a text. People with analytical skills can examine information, understand what it means, and properly explain to others the implications of that information.
- Asking Thoughtful Questions
- Data Analysis
- Questioning Evidence
- Recognizing Patterns
Often, you will need to share your conclusions with your employers or with a group of colleagues. You need to be able to communicate with others to share your ideas effectively. You might also need to engage in critical thinking in a group. In this case, you will need to work with others and communicate effectively to figure out solutions to complex problems.
- Active Listening
- Verbal Communication
- Written Communication
Critical thinking often involves creativity and innovation. You might need to spot patterns in the information you are looking at or come up with a solution that no one else has thought of before. All of this involves a creative eye that can take a different approach from all other approaches.
- Drawing Connections
To think critically, you need to be able to put aside any assumptions or judgments and merely analyze the information you receive. You need to be objective, evaluating ideas without bias.
Problem-solving is another critical thinking skill that involves analyzing a problem, generating and implementing a solution, and assessing the success of the plan. Employers don’t simply want employees who can think about information critically. They also need to be able to come up with practical solutions.

Developing the right mindset and skills.
By the Mind Tools Content Team
We make hundreds of decisions every day and, whether we realize it or not, we're all critical thinkers.
We use critical thinking each time we weigh up our options, prioritize our responsibilities, or think about the likely effects of our actions. It's a crucial skill that helps us to cut out misinformation and make wise decisions. The trouble is, we're not always very good at it!
In this article, we'll explore the key skills that you need to develop your critical thinking skills, and how to adopt a critical thinking mindset, so that you can make well-informed decisions.
What Is Critical Thinking?
Critical thinking is the discipline of rigorously and skillfully using information, experience, observation, and reasoning to guide your decisions, actions, and beliefs. You'll need to actively question every step of your thinking process to do it well.
Collecting, analyzing and evaluating information is an important skill in life, and a highly valued asset in the workplace. People who score highly in critical thinking assessments are also rated by their managers as having good problem-solving skills, creativity, strong decision-making skills, and good overall performance. 
Key Critical Thinking Skills
Critical thinkers possess a set of key characteristics which help them to question information and their own thinking. Focus on the following areas to develop your critical thinking skills:
Being willing and able to explore alternative approaches and experimental ideas is crucial. Can you think through "what if" scenarios, create plausible options, and test out your theories? If not, you'll tend to write off ideas and options too soon, so you may miss the best answer to your situation.
To nurture your curiosity, stay up to date with facts and trends. You'll overlook important information if you allow yourself to become "blinkered," so always be open to new information.
But don't stop there! Look for opposing views or evidence to challenge your information, and seek clarification when things are unclear. This will help you to reassess your beliefs and make a well-informed decision later. Read our article, Opening Closed Minds , for more ways to stay receptive.
You must be skilled at reasoning and extending logic to come up with plausible options or outcomes.
It's also important to emphasize logic over emotion. Emotion can be motivating but it can also lead you to take hasty and unwise action, so control your emotions and be cautious in your judgments. Know when a conclusion is "fact" and when it is not. "Could-be-true" conclusions are based on assumptions and must be tested further. Read our article, Logical Fallacies , for help with this.
Use creative problem solving to balance cold logic. By thinking outside of the box you can identify new possible outcomes by using pieces of information that you already have.
Many of the decisions we make in life are subtly informed by our values and beliefs. These influences are called cognitive biases and it can be difficult to identify them in ourselves because they're often subconscious.
Practicing self-awareness will allow you to reflect on the beliefs you have and the choices you make. You'll then be better equipped to challenge your own thinking and make improved, unbiased decisions.
One particularly useful tool for critical thinking is the Ladder of Inference . It allows you to test and validate your thinking process, rather than jumping to poorly supported conclusions.
Developing a Critical Thinking Mindset
Combine the above skills with the right mindset so that you can make better decisions and adopt more effective courses of action. You can develop your critical thinking mindset by following this process:
First, collect data, opinions and facts on the issue that you need to solve. Draw on what you already know, and turn to new sources of information to help inform your understanding. Consider what gaps there are in your knowledge and seek to fill them. And look for information that challenges your assumptions and beliefs.
Be sure to verify the authority and authenticity of your sources. Not everything you read is true! Use this checklist to ensure that your information is valid:
- Are your information sources trustworthy ? (For example, well-respected authors, trusted colleagues or peers, recognized industry publications, websites, blogs, etc.)
- Is the information you have gathered up to date ?
- Has the information received any direct criticism ?
- Does the information have any errors or inaccuracies ?
- Is there any evidence to support or corroborate the information you have gathered?
- Is the information you have gathered subjective or biased in any way? (For example, is it based on opinion, rather than fact? Is any of the information you have gathered designed to promote a particular service or organization?)
If any information appears to be irrelevant or invalid, don't include it in your decision making. But don't omit information just because you disagree with it, or your final decision will be flawed and bias.
Now observe the information you have gathered, and interpret it. What are the key findings and main takeaways? What does the evidence point to? Start to build one or two possible arguments based on what you have found.
You'll need to look for the details within the mass of information, so use your powers of observation to identify any patterns or similarities. You can then analyze and extend these trends to make sensible predictions about the future.
To help you to sift through the multiple ideas and theories, it can be useful to group and order items according to their characteristics. From here, you can compare and contrast the different items. And once you've determined how similar or different things are from one another, Paired Comparison Analysis can help you to analyze them.
The final step involves challenging the information and rationalizing its arguments.
Apply the laws of reason (induction, deduction, analogy) to judge an argument and determine its merits. To do this, it's essential that you can determine the significance and validity of an argument to put it in the correct perspective. Take a look at our article, Rational Thinking , for more information about how to do this.
Once you have considered all of the arguments and options rationally, you can finally make an informed decision.
Afterward, take time to reflect on what you have learned and what you found challenging. Step back from the detail of your decision or problem, and look at the bigger picture. Record what you've learned from your observations and experience.
Critical thinking involves rigorously and skilfully using information, experience, observation, and reasoning to guide your decisions, actions and beliefs. It's a useful skill in the workplace and in life.
You'll need to be curious and creative to explore alternative possibilities, but rational to apply logic, and self-aware to identify when your beliefs could affect your decisions or actions.
You can demonstrate a high level of critical thinking by validating your information, analyzing its meaning, and finally evaluating the argument.

What is critical thinking?
Critical thinking is a kind of thinking in which you question , analyse , interpret , evaluate and make a judgement about what you read, hear, say, or write. The term critical comes from the Greek word kritikos meaning “able to judge or discern”. Good critical thinking is about making reliable judgements based on reliable information.
Applying critical thinking does not mean being negative or focusing on faults. It means being able to clarify your thinking so that you can break down a problem or a piece of information, interpret it and use that interpretation to arrive at an informed decision or judgement (for example designing a bridge, responding to an opinion piece or understanding a political motivation).
People who apply critical thinking consistently are said to have a critical thinking mindset, but no one is born this way. These are attributes which are learnt and improved through practice and application.
In the academic context, critical thinking is most commonly associated with arguments. You might be asked to think critically about other people's arguments or create your own. To become a better critical thinker, you therefore need to learn how to:
- clarify your thinking purpose and context
- question your sources of information
- identify arguments
- analyse sources and arguments
- evaluate the arguments of others and
- create or synthesise your own arguments.
As the image illustrates, critical thinking skills and attributes are interconnected and need to work together for your critical thinking to be effective.
Six key steps to developing your critical thinking skills and mindset View
Examples of critical thinking skills, mindsets and practices.
Below are four examples of critical thinking skills, mindsets and practices. This is by no means an exhaustive list of all critical thinking skills because the skills you use will depend on your specific context.
How do i apply questioning skills.
- I question the relevance and reliability of what I hear, read or see.
- I question the authority and purpose of what I hear, read or see.
How do I apply a questioning mindset?
- I am inquisitive and curious.
- I always seek the truth, rather than accepting things without questioning.
What does good questioning look like in practice?
- A student reads an academic paper and decides it is suitable to include in their essay as it was published recently by an expert in that specific field and the author’s findings were generated by the most reliable method.
- A person reads a newspaper article editorial and realises the author is not an expert in the field and the arguments they present are intended to persuade the reader to vote for (or against) a certain political party.
- A dietitian advises their patient against the advice the patient has read on the internet stating the benefits of hot chocolate as the dietitian recognises that the research was conducted by a confectionery manufacturer.
How do i apply analytical skills.
- I carefully examine ideas and information.
- I systematically consider all aspects of a problem and look at each element in its wider context.
How do I apply an analytical mindset?
- I make connections between ideas.
What does analysis look like in practice?
- A student breaks down a film into its scenes and compares the choices the director has made with a variety of established film making theories and social science literature to discuss how the film makes a social commentary on a contemporary issue.
- A person watches a news editorial and compares each claim the journalist makes with evidence generated by not-for-profit organisations, which clearly state their agenda to provide accurate data on climate change.
- An epidemiologist collects all the survey data on behaviours during a pandemic and compares each behaviour pattern with the spread of the disease in different areas.
How do i apply evaluation skills.
- I recognise (and avoid) flaws of reasoning.
- I consider what is implied in what I see, hear and read.
How do I apply an evaluation mindset?
- I compare different viewpoints and arguments, and point out their strengths and weaknesses.
What does evaluation look like in practice?
- A student writing a persuasive essay checks they have presented the opposing side of their argument and finds well reasoned evidence to change their point of view and rewrite their essay.
- When listening to a radio commentator’s response to gender diversity in the workplace a person realises the commentator criticises the advocate of the policy and never addresses their argument.
- A psychology researcher collects data from hundreds of participants to prove their hypothesis about the correlation between gun violence and video games, but upon processing their data finds their hypothesis was rejected. The researcher then discloses that their hypothesis was not supported by the data in a respected academic journal.
How do i apply synthesis skills.
- I use logic and reason to formulate my conclusions and arguments.
- I use strong evidence, based on analysis and evaluation, to support my conclusions.
How do I apply a synthesis mindset?
- I consider the bigger picture or context, and use strong evidence and reason to formulate my conclusions, decisions, judgements and arguments.
What does synthesis look like in practice?
- A student conducts a literature review comparing the arguments for and against assisted death in terminally ill patients. They develop the argument that policy at a federal level is required, and logically connect their argument to several recent academic papers and reliable government reports.
- A parent chooses to vaccinate their child against COVID-19 after reading about the benefits and risks in a piece written by a well respected immunologist in The Conversation, and after discussing the decision with their general practitioner.
- A mechanical engineer challenges their supervisor’s approach to the design of a medical device by providing a summary of the experimental data they have collected.

What is Critical Thinking?
Critical thinking is the ability to think clearly and rationally, understanding the logical connection between ideas. Critical thinking has been the subject of much debate and thought since the time of early Greek philosophers such as Plato and Socrates and has continued to be a subject of discussion into the modern age, for example the ability to recognise fake news .
Critical thinking might be described as the ability to engage in reflective and independent thinking.
In essence, critical thinking requires you to use your ability to reason. It is about being an active learner rather than a passive recipient of information.
Critical thinkers rigorously question ideas and assumptions rather than accepting them at face value. They will always seek to determine whether the ideas, arguments and findings represent the entire picture and are open to finding that they do not.
Critical thinkers will identify, analyse and solve problems systematically rather than by intuition or instinct.
Someone with critical thinking skills can:
Understand the links between ideas.
Determine the importance and relevance of arguments and ideas.
Recognise, build and appraise arguments.
Identify inconsistencies and errors in reasoning.
Approach problems in a consistent and systematic way.
Reflect on the justification of their own assumptions, beliefs and values.
Critical thinking is thinking about things in certain ways so as to arrive at the best possible solution in the circumstances that the thinker is aware of. In more everyday language, it is a way of thinking about whatever is presently occupying your mind so that you come to the best possible conclusion.
Critical Thinking is:
A way of thinking about particular things at a particular time; it is not the accumulation of facts and knowledge or something that you can learn once and then use in that form forever, such as the nine times table you learn and use in school.
The Skills We Need for Critical Thinking
The skills that we need in order to be able to think critically are varied and include observation, analysis, interpretation, reflection, evaluation, inference, explanation, problem solving, and decision making.
Specifically we need to be able to:
Think about a topic or issue in an objective and critical way.
Identify the different arguments there are in relation to a particular issue.
Evaluate a point of view to determine how strong or valid it is.
Recognise any weaknesses or negative points that there are in the evidence or argument.
Notice what implications there might be behind a statement or argument.
Provide structured reasoning and support for an argument that we wish to make.
The Critical Thinking Process
You should be aware that none of us think critically all the time.
Sometimes we think in almost any way but critically, for example when our self-control is affected by anger, grief or joy or when we are feeling just plain ‘bloody minded’.
On the other hand, the good news is that, since our critical thinking ability varies according to our current mindset, most of the time we can learn to improve our critical thinking ability by developing certain routine activities and applying them to all problems that present themselves.
Once you understand the theory of critical thinking, improving your critical thinking skills takes persistence and practice.
Try this simple exercise to help you to start thinking critically.
Think of something that someone has recently told you. Then ask yourself the following questions:
Who said it?
Someone you know? Someone in a position of authority or power? Does it matter who told you this?
What did they say?
Did they give facts or opinions? Did they provide all the facts? Did they leave anything out?
Where did they say it?
Was it in public or in private? Did other people have a chance to respond an provide an alternative account?
When did they say it?
Was it before, during or after an important event? Is timing important?
Why did they say it?
Did they explain the reasoning behind their opinion? Were they trying to make someone look good or bad?
How did they say it?
Were they happy or sad, angry or indifferent? Did they write it or say it? Could you understand what was said?
What are you Aiming to Achieve?
One of the most important aspects of critical thinking is to decide what you are aiming to achieve and then make a decision based on a range of possibilities.
Once you have clarified that aim for yourself you should use it as the starting point in all future situations requiring thought and, possibly, further decision making. Where needed, make your workmates, family or those around you aware of your intention to pursue this goal. You must then discipline yourself to keep on track until changing circumstances mean you have to revisit the start of the decision making process.
However, there are things that get in the way of simple decision making. We all carry with us a range of likes and dislikes, learnt behaviours and personal preferences developed throughout our lives; they are the hallmarks of being human. A major contribution to ensuring we think critically is to be aware of these personal characteristics, preferences and biases and make allowance for them when considering possible next steps, whether they are at the pre-action consideration stage or as part of a rethink caused by unexpected or unforeseen impediments to continued progress.
The more clearly we are aware of ourselves, our strengths and weaknesses, the more likely our critical thinking will be productive.
The Benefit of Foresight
Perhaps the most important element of thinking critically is foresight.
Almost all decisions we make and implement don’t prove disastrous if we find reasons to abandon them. However, our decision making will be infinitely better and more likely to lead to success if, when we reach a tentative conclusion, we pause and consider the impact on the people and activities around us.
The elements needing consideration are generally numerous and varied. In many cases, consideration of one element from a different perspective will reveal potential dangers in pursuing our decision.
For instance, moving a business activity to a new location may improve potential output considerably but it may also lead to the loss of skilled workers if the distance moved is too great. Which of these is the more important consideration? Is there some way of lessening the conflict?
These are the sort of problems that may arise from incomplete critical thinking, a demonstration perhaps of the critical importance of good critical thinking.

Critical thinking is aimed at achieving the best possible outcomes in any situation. In order to achieve this it must involve gathering and evaluating information from as many different sources possible.
Critical thinking requires a clear, often uncomfortable, assessment of your personal strengths, weaknesses and preferences and their possible impact on decisions you may make.
Critical thinking requires the development and use of foresight as far as this is possible. As Doris Day sang, “the future’s not ours to see”.
Implementing the decisions made arising from critical thinking must take into account an assessment of possible outcomes and ways of avoiding potentially negative outcomes, or at least lessening their impact.
- Critical thinking involves reviewing the results of the application of decisions made and implementing change where possible.
It might be thought that we are overextending our demands on critical thinking in expecting that it can help to construct focused meaning rather than examining the information given and the knowledge we have acquired to see if we can, if necessary, construct a meaning that will be acceptable and useful.
After all, almost no information we have available to us, either externally or internally, carries any guarantee of its life or appropriateness. Neat step-by-step instructions may provide some sort of trellis on which our basic understanding of critical thinking can blossom but it doesn’t and cannot provide any assurance of certainty, utility or longevity.

Critical thinking is a widely accepted educational goal. Its definition is contested, but the competing definitions can be understood as differing conceptions of the same basic concept: careful thinking directed to a goal. Conceptions differ with respect to the scope of such thinking, the type of goal, the criteria and norms for thinking carefully, and the thinking components on which they focus. Its adoption as an educational goal has been recommended on the basis of respect for students’ autonomy and preparing students for success in life and for democratic citizenship. “Critical thinkers” have the dispositions and abilities that lead them to think critically when appropriate. The abilities can be identified directly; the dispositions indirectly, by considering what factors contribute to or impede exercise of the abilities. Standardized tests have been developed to assess the degree to which a person possesses such dispositions and abilities. Educational intervention has been shown experimentally to improve them, particularly when it includes dialogue, anchored instruction, and mentoring. Controversies have arisen over the generalizability of critical thinking across domains, over alleged bias in critical thinking theories and instruction, and over the relationship of critical thinking to other types of thinking.

Use of the term ‘critical thinking’ to describe an educational goal goes back to the American philosopher John Dewey (1910), who more commonly called it ‘reflective thinking’. He defined it as
active, persistent and careful consideration of any belief or supposed form of knowledge in the light of the grounds that support it, and the further conclusions to which it tends. (Dewey 1910: 6; 1933: 9)
and identified a habit of such consideration with a scientific attitude of mind. His lengthy quotations of Francis Bacon, John Locke, and John Stuart Mill indicate that he was not the first person to propose development of a scientific attitude of mind as an educational goal.
In the 1930s, many of the schools that participated in the Eight-Year Study of the Progressive Education Association (Aikin 1942) adopted critical thinking as an educational goal, for whose achievement the study’s Evaluation Staff developed tests (Smith, Tyler, & Evaluation Staff 1942). Glaser (1941) showed experimentally that it was possible to improve the critical thinking of high school students. Bloom’s influential taxonomy of cognitive educational objectives (Bloom et al. 1956) incorporated critical thinking abilities. Ennis (1962) proposed 12 aspects of critical thinking as a basis for research on the teaching and evaluation of critical thinking ability.
Since 1980, an annual international conference in California on critical thinking and educational reform has attracted tens of thousands of educators from all levels of education and from many parts of the world. Also since 1980, the state university system in California has required all undergraduate students to take a critical thinking course. Since 1983, the Association for Informal Logic and Critical Thinking has sponsored sessions in conjunction with the divisional meetings of the American Philosophical Association (APA). In 1987, the APA’s Committee on Pre-College Philosophy commissioned a consensus statement on critical thinking for purposes of educational assessment and instruction (Facione 1990a). Researchers have developed standardized tests of critical thinking abilities and dispositions; for details, see the Supplement on Assessment . Educational jurisdictions around the world now include critical thinking in guidelines for curriculum and assessment.
For details on this history, see the Supplement on History .
2. Examples and Non-Examples
Before considering the definition of critical thinking, it will be helpful to have in mind some examples of critical thinking, as well as some examples of kinds of thinking that would apparently not count as critical thinking.
Dewey (1910: 68–71; 1933: 91–94) takes as paradigms of reflective thinking three class papers of students in which they describe their thinking. The examples range from the everyday to the scientific.
Transit : “The other day, when I was down town on 16th Street, a clock caught my eye. I saw that the hands pointed to 12:20. This suggested that I had an engagement at 124th Street, at one o’clock. I reasoned that as it had taken me an hour to come down on a surface car, I should probably be twenty minutes late if I returned the same way. I might save twenty minutes by a subway express. But was there a station near? If not, I might lose more than twenty minutes in looking for one. Then I thought of the elevated, and I saw there was such a line within two blocks. But where was the station? If it were several blocks above or below the street I was on, I should lose time instead of gaining it. My mind went back to the subway express as quicker than the elevated; furthermore, I remembered that it went nearer than the elevated to the part of 124th Street I wished to reach, so that time would be saved at the end of the journey. I concluded in favor of the subway, and reached my destination by one o’clock.” (Dewey 1910: 68–69; 1933: 91–92)
Ferryboat : “Projecting nearly horizontally from the upper deck of the ferryboat on which I daily cross the river is a long white pole, having a gilded ball at its tip. It suggested a flagpole when I first saw it; its color, shape, and gilded ball agreed with this idea, and these reasons seemed to justify me in this belief. But soon difficulties presented themselves. The pole was nearly horizontal, an unusual position for a flagpole; in the next place, there was no pulley, ring, or cord by which to attach a flag; finally, there were elsewhere on the boat two vertical staffs from which flags were occasionally flown. It seemed probable that the pole was not there for flag-flying.
“I then tried to imagine all possible purposes of the pole, and to consider for which of these it was best suited: (a) Possibly it was an ornament. But as all the ferryboats and even the tugboats carried poles, this hypothesis was rejected. (b) Possibly it was the terminal of a wireless telegraph. But the same considerations made this improbable. Besides, the more natural place for such a terminal would be the highest part of the boat, on top of the pilot house. (c) Its purpose might be to point out the direction in which the boat is moving.
“In support of this conclusion, I discovered that the pole was lower than the pilot house, so that the steersman could easily see it. Moreover, the tip was enough higher than the base, so that, from the pilot’s position, it must appear to project far out in front of the boat. Moreover, the pilot being near the front of the boat, he would need some such guide as to its direction. Tugboats would also need poles for such a purpose. This hypothesis was so much more probable than the others that I accepted it. I formed the conclusion that the pole was set up for the purpose of showing the pilot the direction in which the boat pointed, to enable him to steer correctly.” (Dewey 1910: 69–70; 1933: 92–93)
Bubbles : “In washing tumblers in hot soapsuds and placing them mouth downward on a plate, bubbles appeared on the outside of the mouth of the tumblers and then went inside. Why? The presence of bubbles suggests air, which I note must come from inside the tumbler. I see that the soapy water on the plate prevents escape of the air save as it may be caught in bubbles. But why should air leave the tumbler? There was no substance entering to force it out. It must have expanded. It expands by increase of heat, or by decrease of pressure, or both. Could the air have become heated after the tumbler was taken from the hot suds? Clearly not the air that was already entangled in the water. If heated air was the cause, cold air must have entered in transferring the tumblers from the suds to the plate. I test to see if this supposition is true by taking several more tumblers out. Some I shake so as to make sure of entrapping cold air in them. Some I take out holding mouth downward in order to prevent cold air from entering. Bubbles appear on the outside of every one of the former and on none of the latter. I must be right in my inference. Air from the outside must have been expanded by the heat of the tumbler, which explains the appearance of the bubbles on the outside. But why do they then go inside? Cold contracts. The tumbler cooled and also the air inside it. Tension was removed, and hence bubbles appeared inside. To be sure of this, I test by placing a cup of ice on the tumbler while the bubbles are still forming outside. They soon reverse” (Dewey 1910: 70–71; 1933: 93–94).
Dewey (1910, 1933) sprinkles his book with other examples of critical thinking. We will refer to the following.
Weather : A man on a walk notices that it has suddenly become cool, thinks that it is probably going to rain, looks up and sees a dark cloud obscuring the sun, and quickens his steps (1910: 6–10; 1933: 9–13).
Disorder : A man finds his rooms on his return to them in disorder with his belongings thrown about, thinks at first of burglary as an explanation, then thinks of mischievous children as being an alternative explanation, then looks to see whether valuables are missing, and discovers that they are (1910: 82–83; 1933: 166–168).
Typhoid : A physician diagnosing a patient whose conspicuous symptoms suggest typhoid avoids drawing a conclusion until more data are gathered by questioning the patient and by making tests (1910: 85–86; 1933: 170).
Blur : A moving blur catches our eye in the distance, we ask ourselves whether it is a cloud of whirling dust or a tree moving its branches or a man signaling to us, we think of other traits that should be found on each of those possibilities, and we look and see if those traits are found (1910: 102, 108; 1933: 121, 133).
Suction pump : In thinking about the suction pump, the scientist first notes that it will draw water only to a maximum height of 33 feet at sea level and to a lesser maximum height at higher elevations, selects for attention the differing atmospheric pressure at these elevations, sets up experiments in which the air is removed from a vessel containing water (when suction no longer works) and in which the weight of air at various levels is calculated, compares the results of reasoning about the height to which a given weight of air will allow a suction pump to raise water with the observed maximum height at different elevations, and finally assimilates the suction pump to such apparently different phenomena as the siphon and the rising of a balloon (1910: 150–153; 1933: 195–198).
Diamond : A passenger in a car driving in a diamond lane reserved for vehicles with at least one passenger notices that the diamond marks on the pavement are far apart in some places and close together in others. Why? The driver suggests that the reason may be that the diamond marks are not needed where there is a solid double line separating the diamond lane from the adjoining lane, but are needed when there is a dotted single line permitting crossing into the diamond lane. Further observation confirms that the diamonds are close together when a dotted line separates the diamond lane from its neighbour, but otherwise far apart.
Rash : A woman suddenly develops a very itchy red rash on her throat and upper chest. She recently noticed a mark on the back of her right hand, but was not sure whether the mark was a rash or a scrape. She lies down in bed and thinks about what might be causing the rash and what to do about it. About two weeks before, she began taking blood pressure medication that contained a sulfa drug, and the pharmacist had warned her, in view of a previous allergic reaction to a medication containing a sulfa drug, to be on the alert for an allergic reaction; however, she had been taking the medication for two weeks with no such effect. The day before, she began using a new cream on her neck and upper chest; against the new cream as the cause was mark on the back of her hand, which had not been exposed to the cream. She began taking probiotics about a month before. She also recently started new eye drops, but she supposed that manufacturers of eye drops would be careful not to include allergy-causing components in the medication. The rash might be a heat rash, since she recently was sweating profusely from her upper body. Since she is about to go away on a short vacation, where she would not have access to her usual physician, she decides to keep taking the probiotics and using the new eye drops but to discontinue the blood pressure medication and to switch back to the old cream for her neck and upper chest. She forms a plan to consult her regular physician on her return about the blood pressure medication.
Candidate : Although Dewey included no examples of thinking directed at appraising the arguments of others, such thinking has come to be considered a kind of critical thinking. We find an example of such thinking in the performance task on the Collegiate Learning Assessment (CLA+), which its sponsoring organization describes as
a performance-based assessment that provides a measure of an institution’s contribution to the development of critical-thinking and written communication skills of its students. (Council for Aid to Education 2017)
A sample task posted on its website requires the test-taker to write a report for public distribution evaluating a fictional candidate’s policy proposals and their supporting arguments, using supplied background documents, with a recommendation on whether to endorse the candidate.
Immediate acceptance of an idea that suggests itself as a solution to a problem (e.g., a possible explanation of an event or phenomenon, an action that seems likely to produce a desired result) is “uncritical thinking, the minimum of reflection” (Dewey 1910: 13). On-going suspension of judgment in the light of doubt about a possible solution is not critical thinking (Dewey 1910: 108). Critique driven by a dogmatically held political or religious ideology is not critical thinking; thus Paulo Freire (1968 ) is using the term (e.g., at 1970: 71, 81, 100, 146) in a more politically freighted sense that includes not only reflection but also revolutionary action against oppression. Derivation of a conclusion from given data using an algorithm is not critical thinking.
What is critical thinking? There are many definitions. Ennis (2016) lists 14 philosophically oriented scholarly definitions and three dictionary definitions. Following Rawls (1971), who distinguished his conception of justice from a utilitarian conception but regarded them as rival conceptions of the same concept, Ennis maintains that the 17 definitions are different conceptions of the same concept. Rawls articulated the shared concept of justice as
a characteristic set of principles for assigning basic rights and duties and for determining… the proper distribution of the benefits and burdens of social cooperation. (Rawls 1971: 5)
Bailin et al. (1999b) claim that, if one considers what sorts of thinking an educator would take not to be critical thinking and what sorts to be critical thinking, one can conclude that educators typically understand critical thinking to have at least three features.
- It is done for the purpose of making up one’s mind about what to believe or do.
- The person engaging in the thinking is trying to fulfill standards of adequacy and accuracy appropriate to the thinking.
- The thinking fulfills the relevant standards to some threshold level.
One could sum up the core concept that involves these three features by saying that critical thinking is careful goal-directed thinking. This core concept seems to apply to all the examples of critical thinking described in the previous section. As for the non-examples, their exclusion depends on construing careful thinking as excluding jumping immediately to conclusions, suspending judgment no matter how strong the evidence, reasoning from an unquestioned ideological or religious perspective, and routinely using an algorithm to answer a question.
If the core of critical thinking is careful goal-directed thinking, conceptions of it can vary according to its presumed scope, its presumed goal, one’s criteria and threshold for being careful, and the thinking component on which one focuses. As to its scope, some conceptions (e.g., Dewey 1910, 1933) restrict it to constructive thinking on the basis of one’s own observations and experiments, others (e.g., Ennis 1962; Fisher & Scriven 1997; Johnson 1992) to appraisal of the products of such thinking. Ennis (1991) and Bailin et al. (1999b) take it to cover both construction and appraisal. As to its goal, some conceptions restrict it to forming a judgment (Dewey 1910, 1933; Lipman 1987; Facione 1990a). Others allow for actions as well as beliefs as the end point of a process of critical thinking (Ennis 1991; Bailin et al. 1999b). As to the criteria and threshold for being careful, definitions vary in the term used to indicate that critical thinking satisfies certain norms: “intellectually disciplined” (Scriven & Paul 1987), “reasonable” (Ennis 1991), “skillful” (Lipman 1987), “skilled” (Fisher & Scriven 1997), “careful” (Bailin & Battersby 2009). Some definitions specify these norms, referring variously to “consideration of any belief or supposed form of knowledge in the light of the grounds that support it and the further conclusions to which it tends” (Dewey 1910, 1933); “the methods of logical inquiry and reasoning” (Glaser 1941); “conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication” (Scriven & Paul 1987); the requirement that “it is sensitive to context, relies on criteria, and is self-correcting” (Lipman 1987); “evidential, conceptual, methodological, criteriological, or contextual considerations” (Facione 1990a); and “plus-minus considerations of the product in terms of appropriate standards (or criteria)” (Johnson 1992). Stanovich and Stanovich (2010) propose to ground the concept of critical thinking in the concept of rationality, which they understand as combining epistemic rationality (fitting one’s beliefs to the world) and instrumental rationality (optimizing goal fulfillment); a critical thinker, in their view, is someone with “a propensity to override suboptimal responses from the autonomous mind” (2010: 227). These variant specifications of norms for critical thinking are not necessarily incompatible with one another, and in any case presuppose the core notion of thinking carefully. As to the thinking component singled out, some definitions focus on suspension of judgment during the thinking (Dewey 1910; McPeck 1981), others on inquiry while judgment is suspended (Bailin & Battersby 2009, 2021), others on the resulting judgment (Facione 1990a), and still others on responsiveness to reasons (Siegel 1988). Kuhn (2019) takes critical thinking to be more a dialogic practice of advancing and responding to arguments than an individual ability.
In educational contexts, a definition of critical thinking is a “programmatic definition” (Scheffler 1960: 19). It expresses a practical program for achieving an educational goal. For this purpose, a one-sentence formulaic definition is much less useful than articulation of a critical thinking process, with criteria and standards for the kinds of thinking that the process may involve. The real educational goal is recognition, adoption and implementation by students of those criteria and standards. That adoption and implementation in turn consists in acquiring the knowledge, abilities and dispositions of a critical thinker.
Conceptions of critical thinking generally do not include moral integrity as part of the concept. Dewey, for example, took critical thinking to be the ultimate intellectual goal of education, but distinguished it from the development of social cooperation among school children, which he took to be the central moral goal. Ennis (1996, 2011) added to his previous list of critical thinking dispositions a group of dispositions to care about the dignity and worth of every person, which he described as a “correlative” (1996) disposition without which critical thinking would be less valuable and perhaps harmful. An educational program that aimed at developing critical thinking but not the correlative disposition to care about the dignity and worth of every person, he asserted, “would be deficient and perhaps dangerous” (Ennis 1996: 172).
Dewey thought that education for reflective thinking would be of value to both the individual and society; recognition in educational practice of the kinship to the scientific attitude of children’s native curiosity, fertile imagination and love of experimental inquiry “would make for individual happiness and the reduction of social waste” (Dewey 1910: iii). Schools participating in the Eight-Year Study took development of the habit of reflective thinking and skill in solving problems as a means to leading young people to understand, appreciate and live the democratic way of life characteristic of the United States (Aikin 1942: 17–18, 81). Harvey Siegel (1988: 55–61) has offered four considerations in support of adopting critical thinking as an educational ideal. (1) Respect for persons requires that schools and teachers honour students’ demands for reasons and explanations, deal with students honestly, and recognize the need to confront students’ independent judgment; these requirements concern the manner in which teachers treat students. (2) Education has the task of preparing children to be successful adults, a task that requires development of their self-sufficiency. (3) Education should initiate children into the rational traditions in such fields as history, science and mathematics. (4) Education should prepare children to become democratic citizens, which requires reasoned procedures and critical talents and attitudes. To supplement these considerations, Siegel (1988: 62–90) responds to two objections: the ideology objection that adoption of any educational ideal requires a prior ideological commitment and the indoctrination objection that cultivation of critical thinking cannot escape being a form of indoctrination.
Despite the diversity of our 11 examples, one can recognize a common pattern. Dewey analyzed it as consisting of five phases:
- suggestions , in which the mind leaps forward to a possible solution;
- an intellectualization of the difficulty or perplexity into a problem to be solved, a question for which the answer must be sought;
- the use of one suggestion after another as a leading idea, or hypothesis , to initiate and guide observation and other operations in collection of factual material;
- the mental elaboration of the idea or supposition as an idea or supposition ( reasoning , in the sense on which reasoning is a part, not the whole, of inference); and
- testing the hypothesis by overt or imaginative action. (Dewey 1933: 106–107; italics in original)
The process of reflective thinking consisting of these phases would be preceded by a perplexed, troubled or confused situation and followed by a cleared-up, unified, resolved situation (Dewey 1933: 106). The term ‘phases’ replaced the term ‘steps’ (Dewey 1910: 72), thus removing the earlier suggestion of an invariant sequence. Variants of the above analysis appeared in (Dewey 1916: 177) and (Dewey 1938: 101–119).
The variant formulations indicate the difficulty of giving a single logical analysis of such a varied process. The process of critical thinking may have a spiral pattern, with the problem being redefined in the light of obstacles to solving it as originally formulated. For example, the person in Transit might have concluded that getting to the appointment at the scheduled time was impossible and have reformulated the problem as that of rescheduling the appointment for a mutually convenient time. Further, defining a problem does not always follow after or lead immediately to an idea of a suggested solution. Nor should it do so, as Dewey himself recognized in describing the physician in Typhoid as avoiding any strong preference for this or that conclusion before getting further information (Dewey 1910: 85; 1933: 170). People with a hypothesis in mind, even one to which they have a very weak commitment, have a so-called “confirmation bias” (Nickerson 1998): they are likely to pay attention to evidence that confirms the hypothesis and to ignore evidence that counts against it or for some competing hypothesis. Detectives, intelligence agencies, and investigators of airplane accidents are well advised to gather relevant evidence systematically and to postpone even tentative adoption of an explanatory hypothesis until the collected evidence rules out with the appropriate degree of certainty all but one explanation. Dewey’s analysis of the critical thinking process can be faulted as well for requiring acceptance or rejection of a possible solution to a defined problem, with no allowance for deciding in the light of the available evidence to suspend judgment. Further, given the great variety of kinds of problems for which reflection is appropriate, there is likely to be variation in its component events. Perhaps the best way to conceptualize the critical thinking process is as a checklist whose component events can occur in a variety of orders, selectively, and more than once. These component events might include (1) noticing a difficulty, (2) defining the problem, (3) dividing the problem into manageable sub-problems, (4) formulating a variety of possible solutions to the problem or sub-problem, (5) determining what evidence is relevant to deciding among possible solutions to the problem or sub-problem, (6) devising a plan of systematic observation or experiment that will uncover the relevant evidence, (7) carrying out the plan of systematic observation or experimentation, (8) noting the results of the systematic observation or experiment, (9) gathering relevant testimony and information from others, (10) judging the credibility of testimony and information gathered from others, (11) drawing conclusions from gathered evidence and accepted testimony, and (12) accepting a solution that the evidence adequately supports (cf. Hitchcock 2017: 485).
Checklist conceptions of the process of critical thinking are open to the objection that they are too mechanical and procedural to fit the multi-dimensional and emotionally charged issues for which critical thinking is urgently needed (Paul 1984). For such issues, a more dialectical process is advocated, in which competing relevant world views are identified, their implications explored, and some sort of creative synthesis attempted.
If one considers the critical thinking process illustrated by the 11 examples, one can identify distinct kinds of mental acts and mental states that form part of it. To distinguish, label and briefly characterize these components is a useful preliminary to identifying abilities, skills, dispositions, attitudes, habits and the like that contribute causally to thinking critically. Identifying such abilities and habits is in turn a useful preliminary to setting educational goals. Setting the goals is in its turn a useful preliminary to designing strategies for helping learners to achieve the goals and to designing ways of measuring the extent to which learners have done so. Such measures provide both feedback to learners on their achievement and a basis for experimental research on the effectiveness of various strategies for educating people to think critically. Let us begin, then, by distinguishing the kinds of mental acts and mental events that can occur in a critical thinking process.
- Observing : One notices something in one’s immediate environment (sudden cooling of temperature in Weather , bubbles forming outside a glass and then going inside in Bubbles , a moving blur in the distance in Blur , a rash in Rash ). Or one notes the results of an experiment or systematic observation (valuables missing in Disorder , no suction without air pressure in Suction pump )
- Feeling : One feels puzzled or uncertain about something (how to get to an appointment on time in Transit , why the diamonds vary in spacing in Diamond ). One wants to resolve this perplexity. One feels satisfaction once one has worked out an answer (to take the subway express in Transit , diamonds closer when needed as a warning in Diamond ).
- Wondering : One formulates a question to be addressed (why bubbles form outside a tumbler taken from hot water in Bubbles , how suction pumps work in Suction pump , what caused the rash in Rash ).
- Imagining : One thinks of possible answers (bus or subway or elevated in Transit , flagpole or ornament or wireless communication aid or direction indicator in Ferryboat , allergic reaction or heat rash in Rash ).
- Inferring : One works out what would be the case if a possible answer were assumed (valuables missing if there has been a burglary in Disorder , earlier start to the rash if it is an allergic reaction to a sulfa drug in Rash ). Or one draws a conclusion once sufficient relevant evidence is gathered (take the subway in Transit , burglary in Disorder , discontinue blood pressure medication and new cream in Rash ).
- Knowledge : One uses stored knowledge of the subject-matter to generate possible answers or to infer what would be expected on the assumption of a particular answer (knowledge of a city’s public transit system in Transit , of the requirements for a flagpole in Ferryboat , of Boyle’s law in Bubbles , of allergic reactions in Rash ).
- Experimenting : One designs and carries out an experiment or a systematic observation to find out whether the results deduced from a possible answer will occur (looking at the location of the flagpole in relation to the pilot’s position in Ferryboat , putting an ice cube on top of a tumbler taken from hot water in Bubbles , measuring the height to which a suction pump will draw water at different elevations in Suction pump , noticing the spacing of diamonds when movement to or from a diamond lane is allowed in Diamond ).
- Consulting : One finds a source of information, gets the information from the source, and makes a judgment on whether to accept it. None of our 11 examples include searching for sources of information. In this respect they are unrepresentative, since most people nowadays have almost instant access to information relevant to answering any question, including many of those illustrated by the examples. However, Candidate includes the activities of extracting information from sources and evaluating its credibility.
- Identifying and analyzing arguments : One notices an argument and works out its structure and content as a preliminary to evaluating its strength. This activity is central to Candidate . It is an important part of a critical thinking process in which one surveys arguments for various positions on an issue.
- Judging : One makes a judgment on the basis of accumulated evidence and reasoning, such as the judgment in Ferryboat that the purpose of the pole is to provide direction to the pilot.
- Deciding : One makes a decision on what to do or on what policy to adopt, as in the decision in Transit to take the subway.
By definition, a person who does something voluntarily is both willing and able to do that thing at that time. Both the willingness and the ability contribute causally to the person’s action, in the sense that the voluntary action would not occur if either (or both) of these were lacking. For example, suppose that one is standing with one’s arms at one’s sides and one voluntarily lifts one’s right arm to an extended horizontal position. One would not do so if one were unable to lift one’s arm, if for example one’s right side was paralyzed as the result of a stroke. Nor would one do so if one were unwilling to lift one’s arm, if for example one were participating in a street demonstration at which a white supremacist was urging the crowd to lift their right arm in a Nazi salute and one were unwilling to express support in this way for the racist Nazi ideology. The same analysis applies to a voluntary mental process of thinking critically. It requires both willingness and ability to think critically, including willingness and ability to perform each of the mental acts that compose the process and to coordinate those acts in a sequence that is directed at resolving the initiating perplexity.
Consider willingness first. We can identify causal contributors to willingness to think critically by considering factors that would cause a person who was able to think critically about an issue nevertheless not to do so (Hamby 2014). For each factor, the opposite condition thus contributes causally to willingness to think critically on a particular occasion. For example, people who habitually jump to conclusions without considering alternatives will not think critically about issues that arise, even if they have the required abilities. The contrary condition of willingness to suspend judgment is thus a causal contributor to thinking critically.
Now consider ability. In contrast to the ability to move one’s arm, which can be completely absent because a stroke has left the arm paralyzed, the ability to think critically is a developed ability, whose absence is not a complete absence of ability to think but absence of ability to think well. We can identify the ability to think well directly, in terms of the norms and standards for good thinking. In general, to be able do well the thinking activities that can be components of a critical thinking process, one needs to know the concepts and principles that characterize their good performance, to recognize in particular cases that the concepts and principles apply, and to apply them. The knowledge, recognition and application may be procedural rather than declarative. It may be domain-specific rather than widely applicable, and in either case may need subject-matter knowledge, sometimes of a deep kind.
Reflections of the sort illustrated by the previous two paragraphs have led scholars to identify the knowledge, abilities and dispositions of a “critical thinker”, i.e., someone who thinks critically whenever it is appropriate to do so. We turn now to these three types of causal contributors to thinking critically. We start with dispositions, since arguably these are the most powerful contributors to being a critical thinker, can be fostered at an early stage of a child’s development, and are susceptible to general improvement (Glaser 1941: 175)
8. Critical Thinking Dispositions
Educational researchers use the term ‘dispositions’ broadly for the habits of mind and attitudes that contribute causally to being a critical thinker. Some writers (e.g., Paul & Elder 2006; Hamby 2014; Bailin & Battersby 2016a) propose to use the term ‘virtues’ for this dimension of a critical thinker. The virtues in question, although they are virtues of character, concern the person’s ways of thinking rather than the person’s ways of behaving towards others. They are not moral virtues but intellectual virtues, of the sort articulated by Zagzebski (1996) and discussed by Turri, Alfano, and Greco (2017).
On a realistic conception, thinking dispositions or intellectual virtues are real properties of thinkers. They are general tendencies, propensities, or inclinations to think in particular ways in particular circumstances, and can be genuinely explanatory (Siegel 1999). Sceptics argue that there is no evidence for a specific mental basis for the habits of mind that contribute to thinking critically, and that it is pedagogically misleading to posit such a basis (Bailin et al. 1999a). Whatever their status, critical thinking dispositions need motivation for their initial formation in a child—motivation that may be external or internal. As children develop, the force of habit will gradually become important in sustaining the disposition (Nieto & Valenzuela 2012). Mere force of habit, however, is unlikely to sustain critical thinking dispositions. Critical thinkers must value and enjoy using their knowledge and abilities to think things through for themselves. They must be committed to, and lovers of, inquiry.
A person may have a critical thinking disposition with respect to only some kinds of issues. For example, one could be open-minded about scientific issues but not about religious issues. Similarly, one could be confident in one’s ability to reason about the theological implications of the existence of evil in the world but not in one’s ability to reason about the best design for a guided ballistic missile.
Facione (1990a: 25) divides “affective dispositions” of critical thinking into approaches to life and living in general and approaches to specific issues, questions or problems. Adapting this distinction, one can usefully divide critical thinking dispositions into initiating dispositions (those that contribute causally to starting to think critically about an issue) and internal dispositions (those that contribute causally to doing a good job of thinking critically once one has started). The two categories are not mutually exclusive. For example, open-mindedness, in the sense of willingness to consider alternative points of view to one’s own, is both an initiating and an internal disposition.
Using the strategy of considering factors that would block people with the ability to think critically from doing so, we can identify as initiating dispositions for thinking critically attentiveness, a habit of inquiry, self-confidence, courage, open-mindedness, willingness to suspend judgment, trust in reason, wanting evidence for one’s beliefs, and seeking the truth. We consider briefly what each of these dispositions amounts to, in each case citing sources that acknowledge them.
- Attentiveness : One will not think critically if one fails to recognize an issue that needs to be thought through. For example, the pedestrian in Weather would not have looked up if he had not noticed that the air was suddenly cooler. To be a critical thinker, then, one needs to be habitually attentive to one’s surroundings, noticing not only what one senses but also sources of perplexity in messages received and in one’s own beliefs and attitudes (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
- Habit of inquiry : Inquiry is effortful, and one needs an internal push to engage in it. For example, the student in Bubbles could easily have stopped at idle wondering about the cause of the bubbles rather than reasoning to a hypothesis, then designing and executing an experiment to test it. Thus willingness to think critically needs mental energy and initiative. What can supply that energy? Love of inquiry, or perhaps just a habit of inquiry. Hamby (2015) has argued that willingness to inquire is the central critical thinking virtue, one that encompasses all the others. It is recognized as a critical thinking disposition by Dewey (1910: 29; 1933: 35), Glaser (1941: 5), Ennis (1987: 12; 1991: 8), Facione (1990a: 25), Bailin et al. (1999b: 294), Halpern (1998: 452), and Facione, Facione, & Giancarlo (2001).
- Self-confidence : Lack of confidence in one’s abilities can block critical thinking. For example, if the woman in Rash lacked confidence in her ability to figure things out for herself, she might just have assumed that the rash on her chest was the allergic reaction to her medication against which the pharmacist had warned her. Thus willingness to think critically requires confidence in one’s ability to inquire (Facione 1990a: 25; Facione, Facione, & Giancarlo 2001).
- Courage : Fear of thinking for oneself can stop one from doing it. Thus willingness to think critically requires intellectual courage (Paul & Elder 2006: 16).
- Open-mindedness : A dogmatic attitude will impede thinking critically. For example, a person who adheres rigidly to a “pro-choice” position on the issue of the legal status of induced abortion is likely to be unwilling to consider seriously the issue of when in its development an unborn child acquires a moral right to life. Thus willingness to think critically requires open-mindedness, in the sense of a willingness to examine questions to which one already accepts an answer but which further evidence or reasoning might cause one to answer differently (Dewey 1933; Facione 1990a; Ennis 1991; Bailin et al. 1999b; Halpern 1998, Facione, Facione, & Giancarlo 2001). Paul (1981) emphasizes open-mindedness about alternative world-views, and recommends a dialectical approach to integrating such views as central to what he calls “strong sense” critical thinking. In three studies, Haran, Ritov, & Mellers (2013) found that actively open-minded thinking, including “the tendency to weigh new evidence against a favored belief, to spend sufficient time on a problem before giving up, and to consider carefully the opinions of others in forming one’s own”, led study participants to acquire information and thus to make accurate estimations.
- Willingness to suspend judgment : Premature closure on an initial solution will block critical thinking. Thus willingness to think critically requires a willingness to suspend judgment while alternatives are explored (Facione 1990a; Ennis 1991; Halpern 1998).
- Trust in reason : Since distrust in the processes of reasoned inquiry will dissuade one from engaging in it, trust in them is an initiating critical thinking disposition (Facione 1990a, 25; Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001; Paul & Elder 2006). In reaction to an allegedly exclusive emphasis on reason in critical thinking theory and pedagogy, Thayer-Bacon (2000) argues that intuition, imagination, and emotion have important roles to play in an adequate conception of critical thinking that she calls “constructive thinking”. From her point of view, critical thinking requires trust not only in reason but also in intuition, imagination, and emotion.
- Seeking the truth : If one does not care about the truth but is content to stick with one’s initial bias on an issue, then one will not think critically about it. Seeking the truth is thus an initiating critical thinking disposition (Bailin et al. 1999b: 294; Facione, Facione, & Giancarlo 2001). A disposition to seek the truth is implicit in more specific critical thinking dispositions, such as trying to be well-informed, considering seriously points of view other than one’s own, looking for alternatives, suspending judgment when the evidence is insufficient, and adopting a position when the evidence supporting it is sufficient.
Some of the initiating dispositions, such as open-mindedness and willingness to suspend judgment, are also internal critical thinking dispositions, in the sense of mental habits or attitudes that contribute causally to doing a good job of critical thinking once one starts the process. But there are many other internal critical thinking dispositions. Some of them are parasitic on one’s conception of good thinking. For example, it is constitutive of good thinking about an issue to formulate the issue clearly and to maintain focus on it. For this purpose, one needs not only the corresponding ability but also the corresponding disposition. Ennis (1991: 8) describes it as the disposition “to determine and maintain focus on the conclusion or question”, Facione (1990a: 25) as “clarity in stating the question or concern”. Other internal dispositions are motivators to continue or adjust the critical thinking process, such as willingness to persist in a complex task and willingness to abandon nonproductive strategies in an attempt to self-correct (Halpern 1998: 452). For a list of identified internal critical thinking dispositions, see the Supplement on Internal Critical Thinking Dispositions .
Some theorists postulate skills, i.e., acquired abilities, as operative in critical thinking. It is not obvious, however, that a good mental act is the exercise of a generic acquired skill. Inferring an expected time of arrival, as in Transit , has some generic components but also uses non-generic subject-matter knowledge. Bailin et al. (1999a) argue against viewing critical thinking skills as generic and discrete, on the ground that skilled performance at a critical thinking task cannot be separated from knowledge of concepts and from domain-specific principles of good thinking. Talk of skills, they concede, is unproblematic if it means merely that a person with critical thinking skills is capable of intelligent performance.
Despite such scepticism, theorists of critical thinking have listed as general contributors to critical thinking what they variously call abilities (Glaser 1941; Ennis 1962, 1991), skills (Facione 1990a; Halpern 1998) or competencies (Fisher & Scriven 1997). Amalgamating these lists would produce a confusing and chaotic cornucopia of more than 50 possible educational objectives, with only partial overlap among them. It makes sense instead to try to understand the reasons for the multiplicity and diversity, and to make a selection according to one’s own reasons for singling out abilities to be developed in a critical thinking curriculum. Two reasons for diversity among lists of critical thinking abilities are the underlying conception of critical thinking and the envisaged educational level. Appraisal-only conceptions, for example, involve a different suite of abilities than constructive-only conceptions. Some lists, such as those in (Glaser 1941), are put forward as educational objectives for secondary school students, whereas others are proposed as objectives for college students (e.g., Facione 1990a).
The abilities described in the remaining paragraphs of this section emerge from reflection on the general abilities needed to do well the thinking activities identified in section 6 as components of the critical thinking process described in section 5 . The derivation of each collection of abilities is accompanied by citation of sources that list such abilities and of standardized tests that claim to test them.
Observational abilities : Careful and accurate observation sometimes requires specialist expertise and practice, as in the case of observing birds and observing accident scenes. However, there are general abilities of noticing what one’s senses are picking up from one’s environment and of being able to articulate clearly and accurately to oneself and others what one has observed. It helps in exercising them to be able to recognize and take into account factors that make one’s observation less trustworthy, such as prior framing of the situation, inadequate time, deficient senses, poor observation conditions, and the like. It helps as well to be skilled at taking steps to make one’s observation more trustworthy, such as moving closer to get a better look, measuring something three times and taking the average, and checking what one thinks one is observing with someone else who is in a good position to observe it. It also helps to be skilled at recognizing respects in which one’s report of one’s observation involves inference rather than direct observation, so that one can then consider whether the inference is justified. These abilities come into play as well when one thinks about whether and with what degree of confidence to accept an observation report, for example in the study of history or in a criminal investigation or in assessing news reports. Observational abilities show up in some lists of critical thinking abilities (Ennis 1962: 90; Facione 1990a: 16; Ennis 1991: 9). There are items testing a person’s ability to judge the credibility of observation reports in the Cornell Critical Thinking Tests, Levels X and Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). Norris and King (1983, 1985, 1990a, 1990b) is a test of ability to appraise observation reports.
Emotional abilities : The emotions that drive a critical thinking process are perplexity or puzzlement, a wish to resolve it, and satisfaction at achieving the desired resolution. Children experience these emotions at an early age, without being trained to do so. Education that takes critical thinking as a goal needs only to channel these emotions and to make sure not to stifle them. Collaborative critical thinking benefits from ability to recognize one’s own and others’ emotional commitments and reactions.
Questioning abilities : A critical thinking process needs transformation of an inchoate sense of perplexity into a clear question. Formulating a question well requires not building in questionable assumptions, not prejudging the issue, and using language that in context is unambiguous and precise enough (Ennis 1962: 97; 1991: 9).
Imaginative abilities : Thinking directed at finding the correct causal explanation of a general phenomenon or particular event requires an ability to imagine possible explanations. Thinking about what policy or plan of action to adopt requires generation of options and consideration of possible consequences of each option. Domain knowledge is required for such creative activity, but a general ability to imagine alternatives is helpful and can be nurtured so as to become easier, quicker, more extensive, and deeper (Dewey 1910: 34–39; 1933: 40–47). Facione (1990a) and Halpern (1998) include the ability to imagine alternatives as a critical thinking ability.
Inferential abilities : The ability to draw conclusions from given information, and to recognize with what degree of certainty one’s own or others’ conclusions follow, is universally recognized as a general critical thinking ability. All 11 examples in section 2 of this article include inferences, some from hypotheses or options (as in Transit , Ferryboat and Disorder ), others from something observed (as in Weather and Rash ). None of these inferences is formally valid. Rather, they are licensed by general, sometimes qualified substantive rules of inference (Toulmin 1958) that rest on domain knowledge—that a bus trip takes about the same time in each direction, that the terminal of a wireless telegraph would be located on the highest possible place, that sudden cooling is often followed by rain, that an allergic reaction to a sulfa drug generally shows up soon after one starts taking it. It is a matter of controversy to what extent the specialized ability to deduce conclusions from premisses using formal rules of inference is needed for critical thinking. Dewey (1933) locates logical forms in setting out the products of reflection rather than in the process of reflection. Ennis (1981a), on the other hand, maintains that a liberally-educated person should have the following abilities: to translate natural-language statements into statements using the standard logical operators, to use appropriately the language of necessary and sufficient conditions, to deal with argument forms and arguments containing symbols, to determine whether in virtue of an argument’s form its conclusion follows necessarily from its premisses, to reason with logically complex propositions, and to apply the rules and procedures of deductive logic. Inferential abilities are recognized as critical thinking abilities by Glaser (1941: 6), Facione (1990a: 9), Ennis (1991: 9), Fisher & Scriven (1997: 99, 111), and Halpern (1998: 452). Items testing inferential abilities constitute two of the five subtests of the Watson Glaser Critical Thinking Appraisal (Watson & Glaser 1980a, 1980b, 1994), two of the four sections in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), three of the seven sections in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005), 11 of the 34 items on Forms A and B of the California Critical Thinking Skills Test (Facione 1990b, 1992), and a high but variable proportion of the 25 selected-response questions in the Collegiate Learning Assessment (Council for Aid to Education 2017).
Experimenting abilities : Knowing how to design and execute an experiment is important not just in scientific research but also in everyday life, as in Rash . Dewey devoted a whole chapter of his How We Think (1910: 145–156; 1933: 190–202) to the superiority of experimentation over observation in advancing knowledge. Experimenting abilities come into play at one remove in appraising reports of scientific studies. Skill in designing and executing experiments includes the acknowledged abilities to appraise evidence (Glaser 1941: 6), to carry out experiments and to apply appropriate statistical inference techniques (Facione 1990a: 9), to judge inductions to an explanatory hypothesis (Ennis 1991: 9), and to recognize the need for an adequately large sample size (Halpern 1998). The Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) includes four items (out of 52) on experimental design. The Collegiate Learning Assessment (Council for Aid to Education 2017) makes room for appraisal of study design in both its performance task and its selected-response questions.
Consulting abilities : Skill at consulting sources of information comes into play when one seeks information to help resolve a problem, as in Candidate . Ability to find and appraise information includes ability to gather and marshal pertinent information (Glaser 1941: 6), to judge whether a statement made by an alleged authority is acceptable (Ennis 1962: 84), to plan a search for desired information (Facione 1990a: 9), and to judge the credibility of a source (Ennis 1991: 9). Ability to judge the credibility of statements is tested by 24 items (out of 76) in the Cornell Critical Thinking Test Level X (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005) and by four items (out of 52) in the Cornell Critical Thinking Test Level Z (Ennis & Millman 1971; Ennis, Millman, & Tomko 1985, 2005). The College Learning Assessment’s performance task requires evaluation of whether information in documents is credible or unreliable (Council for Aid to Education 2017).
Argument analysis abilities : The ability to identify and analyze arguments contributes to the process of surveying arguments on an issue in order to form one’s own reasoned judgment, as in Candidate . The ability to detect and analyze arguments is recognized as a critical thinking skill by Facione (1990a: 7–8), Ennis (1991: 9) and Halpern (1998). Five items (out of 34) on the California Critical Thinking Skills Test (Facione 1990b, 1992) test skill at argument analysis. The College Learning Assessment (Council for Aid to Education 2017) incorporates argument analysis in its selected-response tests of critical reading and evaluation and of critiquing an argument.
Judging skills and deciding skills : Skill at judging and deciding is skill at recognizing what judgment or decision the available evidence and argument supports, and with what degree of confidence. It is thus a component of the inferential skills already discussed.
Lists and tests of critical thinking abilities often include two more abilities: identifying assumptions and constructing and evaluating definitions.
In addition to dispositions and abilities, critical thinking needs knowledge: of critical thinking concepts, of critical thinking principles, and of the subject-matter of the thinking.
We can derive a short list of concepts whose understanding contributes to critical thinking from the critical thinking abilities described in the preceding section. Observational abilities require an understanding of the difference between observation and inference. Questioning abilities require an understanding of the concepts of ambiguity and vagueness. Inferential abilities require an understanding of the difference between conclusive and defeasible inference (traditionally, between deduction and induction), as well as of the difference between necessary and sufficient conditions. Experimenting abilities require an understanding of the concepts of hypothesis, null hypothesis, assumption and prediction, as well as of the concept of statistical significance and of its difference from importance. They also require an understanding of the difference between an experiment and an observational study, and in particular of the difference between a randomized controlled trial, a prospective correlational study and a retrospective (case-control) study. Argument analysis abilities require an understanding of the concepts of argument, premiss, assumption, conclusion and counter-consideration. Additional critical thinking concepts are proposed by Bailin et al. (1999b: 293), Fisher & Scriven (1997: 105–106), Black (2012), and Blair (2021).
According to Glaser (1941: 25), ability to think critically requires knowledge of the methods of logical inquiry and reasoning. If we review the list of abilities in the preceding section, however, we can see that some of them can be acquired and exercised merely through practice, possibly guided in an educational setting, followed by feedback. Searching intelligently for a causal explanation of some phenomenon or event requires that one consider a full range of possible causal contributors, but it seems more important that one implements this principle in one’s practice than that one is able to articulate it. What is important is “operational knowledge” of the standards and principles of good thinking (Bailin et al. 1999b: 291–293). But the development of such critical thinking abilities as designing an experiment or constructing an operational definition can benefit from learning their underlying theory. Further, explicit knowledge of quirks of human thinking seems useful as a cautionary guide. Human memory is not just fallible about details, as people learn from their own experiences of misremembering, but is so malleable that a detailed, clear and vivid recollection of an event can be a total fabrication (Loftus 2017). People seek or interpret evidence in ways that are partial to their existing beliefs and expectations, often unconscious of their “confirmation bias” (Nickerson 1998). Not only are people subject to this and other cognitive biases (Kahneman 2011), of which they are typically unaware, but it may be counter-productive for one to make oneself aware of them and try consciously to counteract them or to counteract social biases such as racial or sexual stereotypes (Kenyon & Beaulac 2014). It is helpful to be aware of these facts and of the superior effectiveness of blocking the operation of biases—for example, by making an immediate record of one’s observations, refraining from forming a preliminary explanatory hypothesis, blind refereeing, double-blind randomized trials, and blind grading of students’ work. It is also helpful to be aware of the prevalence of “noise” (unwanted unsystematic variability of judgments), of how to detect noise (through a noise audit), and of how to reduce noise: make accuracy the goal, think statistically, break a process of arriving at a judgment into independent tasks, resist premature intuitions, in a group get independent judgments first, favour comparative judgments and scales (Kahneman, Sibony, & Sunstein 2021). It is helpful as well to be aware of the concept of “bounded rationality” in decision-making and of the related distinction between “satisficing” and optimizing (Simon 1956; Gigerenzer 2001).
Critical thinking about an issue requires substantive knowledge of the domain to which the issue belongs. Critical thinking abilities are not a magic elixir that can be applied to any issue whatever by somebody who has no knowledge of the facts relevant to exploring that issue. For example, the student in Bubbles needed to know that gases do not penetrate solid objects like a glass, that air expands when heated, that the volume of an enclosed gas varies directly with its temperature and inversely with its pressure, and that hot objects will spontaneously cool down to the ambient temperature of their surroundings unless kept hot by insulation or a source of heat. Critical thinkers thus need a rich fund of subject-matter knowledge relevant to the variety of situations they encounter. This fact is recognized in the inclusion among critical thinking dispositions of a concern to become and remain generally well informed.
Experimental educational interventions, with control groups, have shown that education can improve critical thinking skills and dispositions, as measured by standardized tests. For information about these tests, see the Supplement on Assessment .
What educational methods are most effective at developing the dispositions, abilities and knowledge of a critical thinker? In a comprehensive meta-analysis of experimental and quasi-experimental studies of strategies for teaching students to think critically, Abrami et al. (2015) found that dialogue, anchored instruction, and mentoring each increased the effectiveness of the educational intervention, and that they were most effective when combined. They also found that in these studies a combination of separate instruction in critical thinking with subject-matter instruction in which students are encouraged to think critically was more effective than either by itself. However, the difference was not statistically significant; that is, it might have arisen by chance.
Most of these studies lack the longitudinal follow-up required to determine whether the observed differential improvements in critical thinking abilities or dispositions continue over time, for example until high school or college graduation. For details on studies of methods of developing critical thinking skills and dispositions, see the Supplement on Educational Methods .
Scholars have denied the generalizability of critical thinking abilities across subject domains, have alleged bias in critical thinking theory and pedagogy, and have investigated the relationship of critical thinking to other kinds of thinking.
McPeck (1981) attacked the thinking skills movement of the 1970s, including the critical thinking movement. He argued that there are no general thinking skills, since thinking is always thinking about some subject-matter. It is futile, he claimed, for schools and colleges to teach thinking as if it were a separate subject. Rather, teachers should lead their pupils to become autonomous thinkers by teaching school subjects in a way that brings out their cognitive structure and that encourages and rewards discussion and argument. As some of his critics (e.g., Paul 1985; Siegel 1985) pointed out, McPeck’s central argument needs elaboration, since it has obvious counter-examples in writing and speaking, for which (up to a certain level of complexity) there are teachable general abilities even though they are always about some subject-matter. To make his argument convincing, McPeck needs to explain how thinking differs from writing and speaking in a way that does not permit useful abstraction of its components from the subject-matters with which it deals. He has not done so. Nevertheless, his position that the dispositions and abilities of a critical thinker are best developed in the context of subject-matter instruction is shared by many theorists of critical thinking, including Dewey (1910, 1933), Glaser (1941), Passmore (1980), Weinstein (1990), Bailin et al. (1999b), and Willingham (2019).
McPeck’s challenge prompted reflection on the extent to which critical thinking is subject-specific. McPeck argued for a strong subject-specificity thesis, according to which it is a conceptual truth that all critical thinking abilities are specific to a subject. (He did not however extend his subject-specificity thesis to critical thinking dispositions. In particular, he took the disposition to suspend judgment in situations of cognitive dissonance to be a general disposition.) Conceptual subject-specificity is subject to obvious counter-examples, such as the general ability to recognize confusion of necessary and sufficient conditions. A more modest thesis, also endorsed by McPeck, is epistemological subject-specificity, according to which the norms of good thinking vary from one field to another. Epistemological subject-specificity clearly holds to a certain extent; for example, the principles in accordance with which one solves a differential equation are quite different from the principles in accordance with which one determines whether a painting is a genuine Picasso. But the thesis suffers, as Ennis (1989) points out, from vagueness of the concept of a field or subject and from the obvious existence of inter-field principles, however broadly the concept of a field is construed. For example, the principles of hypothetico-deductive reasoning hold for all the varied fields in which such reasoning occurs. A third kind of subject-specificity is empirical subject-specificity, according to which as a matter of empirically observable fact a person with the abilities and dispositions of a critical thinker in one area of investigation will not necessarily have them in another area of investigation.
The thesis of empirical subject-specificity raises the general problem of transfer. If critical thinking abilities and dispositions have to be developed independently in each school subject, how are they of any use in dealing with the problems of everyday life and the political and social issues of contemporary society, most of which do not fit into the framework of a traditional school subject? Proponents of empirical subject-specificity tend to argue that transfer is more likely to occur if there is critical thinking instruction in a variety of domains, with explicit attention to dispositions and abilities that cut across domains. But evidence for this claim is scanty. There is a need for well-designed empirical studies that investigate the conditions that make transfer more likely.
It is common ground in debates about the generality or subject-specificity of critical thinking dispositions and abilities that critical thinking about any topic requires background knowledge about the topic. For example, the most sophisticated understanding of the principles of hypothetico-deductive reasoning is of no help unless accompanied by some knowledge of what might be plausible explanations of some phenomenon under investigation.
Critics have objected to bias in the theory, pedagogy and practice of critical thinking. Commentators (e.g., Alston 1995; Ennis 1998) have noted that anyone who takes a position has a bias in the neutral sense of being inclined in one direction rather than others. The critics, however, are objecting to bias in the pejorative sense of an unjustified favoring of certain ways of knowing over others, frequently alleging that the unjustly favoured ways are those of a dominant sex or culture (Bailin 1995). These ways favour:
- reinforcement of egocentric and sociocentric biases over dialectical engagement with opposing world-views (Paul 1981, 1984; Warren 1998)
- distancing from the object of inquiry over closeness to it (Martin 1992; Thayer-Bacon 1992)
- indifference to the situation of others over care for them (Martin 1992)
- orientation to thought over orientation to action (Martin 1992)
- being reasonable over caring to understand people’s ideas (Thayer-Bacon 1993)
- being neutral and objective over being embodied and situated (Thayer-Bacon 1995a)
- doubting over believing (Thayer-Bacon 1995b)
- reason over emotion, imagination and intuition (Thayer-Bacon 2000)
- solitary thinking over collaborative thinking (Thayer-Bacon 2000)
- written and spoken assignments over other forms of expression (Alston 2001)
- attention to written and spoken communications over attention to human problems (Alston 2001)
- winning debates in the public sphere over making and understanding meaning (Alston 2001)
A common thread in this smorgasbord of accusations is dissatisfaction with focusing on the logical analysis and evaluation of reasoning and arguments. While these authors acknowledge that such analysis and evaluation is part of critical thinking and should be part of its conceptualization and pedagogy, they insist that it is only a part. Paul (1981), for example, bemoans the tendency of atomistic teaching of methods of analyzing and evaluating arguments to turn students into more able sophists, adept at finding fault with positions and arguments with which they disagree but even more entrenched in the egocentric and sociocentric biases with which they began. Martin (1992) and Thayer-Bacon (1992) cite with approval the self-reported intimacy with their subject-matter of leading researchers in biology and medicine, an intimacy that conflicts with the distancing allegedly recommended in standard conceptions and pedagogy of critical thinking. Thayer-Bacon (2000) contrasts the embodied and socially embedded learning of her elementary school students in a Montessori school, who used their imagination, intuition and emotions as well as their reason, with conceptions of critical thinking as
thinking that is used to critique arguments, offer justifications, and make judgments about what are the good reasons, or the right answers. (Thayer-Bacon 2000: 127–128)
Alston (2001) reports that her students in a women’s studies class were able to see the flaws in the Cinderella myth that pervades much romantic fiction but in their own romantic relationships still acted as if all failures were the woman’s fault and still accepted the notions of love at first sight and living happily ever after. Students, she writes, should
be able to connect their intellectual critique to a more affective, somatic, and ethical account of making risky choices that have sexist, racist, classist, familial, sexual, or other consequences for themselves and those both near and far… critical thinking that reads arguments, texts, or practices merely on the surface without connections to feeling/desiring/doing or action lacks an ethical depth that should infuse the difference between mere cognitive activity and something we want to call critical thinking. (Alston 2001: 34)
Some critics portray such biases as unfair to women. Thayer-Bacon (1992), for example, has charged modern critical thinking theory with being sexist, on the ground that it separates the self from the object and causes one to lose touch with one’s inner voice, and thus stigmatizes women, who (she asserts) link self to object and listen to their inner voice. Her charge does not imply that women as a group are on average less able than men to analyze and evaluate arguments. Facione (1990c) found no difference by sex in performance on his California Critical Thinking Skills Test. Kuhn (1991: 280–281) found no difference by sex in either the disposition or the competence to engage in argumentative thinking.
The critics propose a variety of remedies for the biases that they allege. In general, they do not propose to eliminate or downplay critical thinking as an educational goal. Rather, they propose to conceptualize critical thinking differently and to change its pedagogy accordingly. Their pedagogical proposals arise logically from their objections. They can be summarized as follows:
- Focus on argument networks with dialectical exchanges reflecting contesting points of view rather than on atomic arguments, so as to develop “strong sense” critical thinking that transcends egocentric and sociocentric biases (Paul 1981, 1984).
- Foster closeness to the subject-matter and feeling connected to others in order to inform a humane democracy (Martin 1992).
- Develop “constructive thinking” as a social activity in a community of physically embodied and socially embedded inquirers with personal voices who value not only reason but also imagination, intuition and emotion (Thayer-Bacon 2000).
- In developing critical thinking in school subjects, treat as important neither skills nor dispositions but opening worlds of meaning (Alston 2001).
- Attend to the development of critical thinking dispositions as well as skills, and adopt the “critical pedagogy” practised and advocated by Freire (1968 ) and hooks (1994) (Dalgleish, Girard, & Davies 2017).
A common thread in these proposals is treatment of critical thinking as a social, interactive, personally engaged activity like that of a quilting bee or a barn-raising (Thayer-Bacon 2000) rather than as an individual, solitary, distanced activity symbolized by Rodin’s The Thinker . One can get a vivid description of education with the former type of goal from the writings of bell hooks (1994, 2010). Critical thinking for her is open-minded dialectical exchange across opposing standpoints and from multiple perspectives, a conception similar to Paul’s “strong sense” critical thinking (Paul 1981). She abandons the structure of domination in the traditional classroom. In an introductory course on black women writers, for example, she assigns students to write an autobiographical paragraph about an early racial memory, then to read it aloud as the others listen, thus affirming the uniqueness and value of each voice and creating a communal awareness of the diversity of the group’s experiences (hooks 1994: 84). Her “engaged pedagogy” is thus similar to the “freedom under guidance” implemented in John Dewey’s Laboratory School of Chicago in the late 1890s and early 1900s. It incorporates the dialogue, anchored instruction, and mentoring that Abrami (2015) found to be most effective in improving critical thinking skills and dispositions.
What is the relationship of critical thinking to problem solving, decision-making, higher-order thinking, creative thinking, and other recognized types of thinking? One’s answer to this question obviously depends on how one defines the terms used in the question. If critical thinking is conceived broadly to cover any careful thinking about any topic for any purpose, then problem solving and decision making will be kinds of critical thinking, if they are done carefully. Historically, ‘critical thinking’ and ‘problem solving’ were two names for the same thing. If critical thinking is conceived more narrowly as consisting solely of appraisal of intellectual products, then it will be disjoint with problem solving and decision making, which are constructive.
Bloom’s taxonomy of educational objectives used the phrase “intellectual abilities and skills” for what had been labeled “critical thinking” by some, “reflective thinking” by Dewey and others, and “problem solving” by still others (Bloom et al. 1956: 38). Thus, the so-called “higher-order thinking skills” at the taxonomy’s top levels of analysis, synthesis and evaluation are just critical thinking skills, although they do not come with general criteria for their assessment (Ennis 1981b). The revised version of Bloom’s taxonomy (Anderson et al. 2001) likewise treats critical thinking as cutting across those types of cognitive process that involve more than remembering (Anderson et al. 2001: 269–270). For details, see the Supplement on History .
As to creative thinking, it overlaps with critical thinking (Bailin 1987, 1988). Thinking about the explanation of some phenomenon or event, as in Ferryboat , requires creative imagination in constructing plausible explanatory hypotheses. Likewise, thinking about a policy question, as in Candidate , requires creativity in coming up with options. Conversely, creativity in any field needs to be balanced by critical appraisal of the draft painting or novel or mathematical theory.

Advice and resources to help you develop your critical voice.
Developing critical thinking skills is essential to your success at University and beyond. We all need to be critical thinkers to help us navigate our way through an information-rich world.
Whatever your discipline, you will engage with a wide variety of sources of information and evidence. You will develop the skills to make judgements about this evidence to form your own views and to present your views clearly.
One of the most common types of feedback received by students is that their work is ‘too descriptive’. This usually means that they have just stated what others have said and have not reflected critically on the material. They have not evaluated the evidence and constructed an argument.
What is critical thinking?
Critical thinking is the art of making clear, reasoned judgements based on interpreting, understanding, applying and synthesising evidence gathered from observation, reading and experimentation. Burns, T., & Sinfield, S. (2016) Essential Study Skills: The Complete Guide to Success at University (4th ed.) London: SAGE, p94.
Being critical does not just mean finding fault. It means assessing evidence from a variety of sources and making reasoned conclusions. As a result of your analysis you may decide that a particular piece of evidence is not robust, or that you disagree with the conclusion, but you should be able to state why you have come to this view and incorporate this into a bigger picture of the literature.
Being critical goes beyond describing what you have heard in lectures or what you have read. It involves synthesising, analysing and evaluating what you have learned to develop your own argument or position.
Critical thinking is important in all subjects and disciplines – in science and engineering, as well as the arts and humanities. The types of evidence used to develop arguments may be very different but the processes and techniques are similar. Critical thinking is required for both undergraduate and postgraduate levels of study.
What, where, when, who, why, how?
Purposeful reading can help with critical thinking because it encourages you to read actively rather than passively. When you read, ask yourself questions about what you are reading and make notes to record your views. Ask questions like:
- What is the main point of this paper/ article/ paragraph/ report/ blog?
- Who wrote it?
- Why was it written?
- When was it written?
- Has the context changed since it was written?
- Is the evidence presented robust?
- How did the authors come to their conclusions?
- Do you agree with the conclusions?
- What does this add to our knowledge?
- Why is it useful?
Our web page covering Reading at university includes a handout to help you develop your own critical reading form and a suggested reading notes record sheet. These resources will help you record your thoughts after you read, which will help you to construct your argument.
Reading at university
Developing an argument
Being a university student is about learning how to think, not what to think. Critical thinking shapes your own values and attitudes through a process of deliberating, debating and persuasion. Through developing your critical thinking you can move on from simply disagreeing to constructively assessing alternatives by building on doubts.
There are several key stages involved in developing your ideas and constructing an argument. You might like to use a form to help you think about the features of critical thinking and to break down the stages of developing your argument.
Features of critical thinking (pdf)
Features of critical thinking (Word rtf)
Our webpage on Academic writing includes a useful handout ‘Building an argument as you go’.
You should also consider the language you will use to introduce a range of viewpoints and to evaluate the various sources of evidence. This will help your reader to follow your argument. To get you started, the University of Manchester's Academic Phrasebank has a useful section on Being Critical .
Developing your critical thinking
Set yourself some tasks to help develop your critical thinking skills. Discuss material presented in lectures or from resource lists with your peers. Set up a critical reading group or use an online discussion forum. Think about a point you would like to make during discussions in tutorials and be prepared to back up your argument with evidence.

How to Improve Your Critical Thinking Skills
Traditional tools and new technologies..
Posted September 29, 2023 | Reviewed by Lybi Ma
Technology provides access to vast information and makes daily life easier. Yet, too much reliance on technology potentially interferes with the acquisition and maintenance of critical thinking skills in several ways:
1. Information Overload : The constant influx of data can discourage deep critical thinking as we may come to rely on quick, surface-level information rather than delving deeply into a subject.
2. Shortened Attention Span: Frequent digital distractions can disrupt our ability for the sustained focus and concentration required for critical thinking.
3. Confirmatory Bias and Echo Chambers: Technology, including social media and personalized content algorithms, can reinforce confirmation bias . People are often exposed to information that aligns with their beliefs and opinions, making them less likely to encounter diverse perspectives and engage in critical thinking about opposing views.
4. Reduced Problem-Solving Opportunities: Technology often provides quick solutions to problems. While this benefits efficiency, it may discourage individuals from engaging in complex problem-solving, a fundamental aspect of critical thinking.
5. Loss of Research Skills: The ease of accessing information online can diminish traditional research skills, such as library research or in-depth reading. These skills are essential for critical thinking, as they involve evaluating sources, synthesizing information, and analyzing complex texts.
While technology can pose challenges to developing critical thinking skills, it's important to note that technology can also be a valuable tool for learning and skill development. It can provide access to educational resources, facilitate collaboration , and support critical thinking when used thoughtfully and intentionally. Balancing technology use with activities that encourage deep thinking and analysis is vital to lessening its potential adverse effects on critical thinking.
Writing is a traditional and powerful tool to exercise and improve your critical thinking skills. Consider these ways writing can help enhance critical thinking:
1. Clarity of Thought: Writing requires that you articulate your thoughts clearly and coherently. When you need to put your ideas on paper, you must organize them logically, which requires a deeper understanding of the subject matter.
2. Analysis and Evaluation: Critical thinking involves analyzing and evaluating information. When you write, you often need to assess the validity and relevance of different sources, arguments, or pieces of evidence, which hone your critical thinking skills.
3. Problem-Solving: Writing can be a problem-solving exercise in itself. Whether crafting an argument, developing a thesis, or finding the right words to express your ideas, writing requires thinking critically about approaching these challenges effectively.
4. Research Skills: Good writing often involves research, and research requires critical thinking. You need to assess the credibility of sources, synthesize information, and draw conclusions based on the evidence you gather.
5. Argumentation: Constructing a persuasive argument in writing is a complex process requiring critical thinking. You must anticipate counterarguments, provide evidence to support your claims, and address potential weaknesses in your reasoning.
6. Revision and Editing: To be an influential writer, you must learn to read your work critically. Editing and revising requires evaluating your writing objectively, identifying areas that need improvement, and refining your ideas and arguments.
7. Problem Identification: In some cases, writing can help you identify problems or gaps in your thinking. As you write, you might realize that your arguments are not as strong as you initially thought or that you need more information to support your claims. This recognition of limitations is a crucial aspect of critical thinking.
Writing is a dynamic process that engages multiple facets of critical thinking. It has been a valuable tool used in education , business, and personal development for centuries.
Yet, this traditional approach of self-generated written thoughts is rapidly being supplanted by AI -generated writing tools like Chat GPT (Generative Pre-trained Transformer. With over 100 million users of Chat GPT alone, we cannot ignore its potential impact. How might the increasing reliance on AI-generated writing tools influence our critical thinking skills? The impact can vary depending on how the tools are used and the context in which they are employed.
Critical thinking involves evaluating information sources for credibility, relevance, and bias. If individuals consistently trust the information provided by chatbots without critically assessing its quality, it can hinder their development of critical thinking skills. This is especially true if they depend on the chatbot to provide answers without questioning or verifying the information. Relying solely on chatbots for answers may also reduce people's effort in problem-solving. Critical thinking often requires wrestling with complex problems, considering multiple perspectives, and generating creative solutions. If we default to chatbots for quick answers, we may miss opportunities to develop these skills.
However, it's essential to note that the impact of chatbots on critical thinking skills may not be entirely negative. These tools can also have positive effects:
1. Chatbots provide quick access to vast information, which can benefit research and problem-solving. When used as a supplement to critical thinking, they can enhance the efficiency of information retrieval.
2. Chatbots can sometimes assist in complex tasks by providing relevant data or suggestions. When individuals critically evaluate and integrate this information into their decision-making process, it can enhance their critical thinking.
3. Chatbots can be used as learning aids. They can provide explanations, examples, and guidance, which can support skill development and, when used effectively, encourage critical thinking.
In summary, the impact of chatbots on critical thinking skills depends on how we use them. The effect will be harmful if they become a crutch to avoid independent thought or analysis. However, they can be valuable resources when used as tools to facilitate and augment critical thinking and writing processes. Individuals must balance leveraging the convenience of chatbots and actively engaging in independent critical thinking and problem-solving to maintain and enhance their cognitive abilities. You can do that effectively through writing regularly.

How to build your critical thinking skills in 7 steps (with examples)
Critical thinking is, well, critical. By building these skills, you improve your ability to analyze information and come to the best decision possible. In this article, we cover the basics of critical thinking, as well as the seven steps you can use to implement the full critical thinking process.
Critical thinking comes from asking the right questions to come to the best conclusion possible. Strong critical thinkers analyze information from a variety of viewpoints in order to identify the best course of action.
Don’t worry if you don’t think you have strong critical thinking abilities. In this article, we’ll help you build a foundation for critical thinking so you can absorb, analyze, and make informed decisions.
What is critical thinking?
Critical thinking is the ability to collect and analyze information to come to a conclusion. Being able to think critically is important in virtually every industry and applicable across a wide range of positions. That’s because critical thinking isn’t subject-specific—rather, it’s your ability to parse through information, data, statistics, and other details in order to identify a satisfactory solution.
Decision-making tools for agile businesses
In this ebook, learn how to equip employees to make better decisions—so your business can pivot, adapt, and tackle challenges more effectively than your competition.
Top 8 critical thinking skills
Like most soft skills, critical thinking isn’t something you can take a class to learn. Rather, this skill consists of a variety of interpersonal and analytical skills. Developing critical thinking is more about learning to embrace open-mindedness and bringing analytical thinking to your problem framing process.
In no particular order, the eight most important critical thinking skills are:
Analytical thinking: Part of critical thinking is evaluating data from multiple sources in order to come to the best conclusions. Analytical thinking allows people to reject bias and strive to gather and consume information to come to the best conclusion.
Open-mindedness: This critical thinking skill helps you analyze and process information to come to an unbiased conclusion. Part of the critical thinking process is letting your personal biases go and coming to a conclusion based on all of the information.
Problem solving : Because critical thinking emphasizes coming to the best conclusion based on all of the available information, it’s a key part of problem solving. When used correctly, critical thinking helps you solve any problem—from a workplace challenge to difficulties in everyday life.
Self-regulation: Self-regulation refers to the ability to regulate your thoughts and set aside any personal biases to come to the best conclusion. In order to be an effective critical thinker, you need to question the information you have and the decisions you favor—only then can you come to the best conclusion.
Observation: Observation skills help critical thinkers look for things beyond face value. To be a critical thinker you need to embrace multiple points of view, and you can use observation skills to identify potential problems.
Interpretation: Not all data is made equal—and critical thinkers know this. In addition to gathering information, it’s important to evaluate which information is important and relevant to your situation. That way, you can draw the best conclusions from the data you’ve collected.
Evaluation: When you attempt to answer a hard question, there is rarely an obvious answer. Even though critical thinking emphasizes putting your biases aside, you need to be able to confidently make a decision based on the data you have available.
Communication: Once a decision has been made, you also need to share this decision with other stakeholders. Effective workplace communication includes presenting evidence and supporting your conclusion—especially if there are a variety of different possible solutions.
7 steps to critical thinking
Critical thinking is a skill that you can build by following these seven steps. The seven steps to critical thinking help you ensure you’re approaching a problem from the right angle, considering every alternative, and coming to an unbiased conclusion.
First things first: When to use the 7 step critical thinking process
There’s a lot that goes into the full critical thinking process, and not every decision needs to be this thought out. Sometimes, it’s enough to put aside bias and approach a process logically. In other, more complex cases, the best way to identify the ideal outcome is to go through the entire critical thinking process.
The seven-step critical thinking process is useful for complex decisions in areas you are less familiar with. Alternatively, the seven critical thinking steps can help you look at a problem you’re familiar with from a different angle, without any bias.
If you need to make a less complex decision, consider another problem solving strategy instead. Decision matrices are a great way to identify the best option between different choices. Check out our article on 7 steps to creating a decision matrix .
1. Identify the problem
Before you put those critical thinking skills to work, you first need to identify the problem you’re solving. This step includes taking a look at the problem from a few different perspectives and asking questions like:
Why is this happening?
What assumptions am I making?
At first glance, how do I think we can solve this problem?
A big part of developing your critical thinking skills is learning how to come to unbiased conclusions. In order to do that, you first need to acknowledge the biases that you currently have. Does someone on your team think they know the answer? Are you making assumptions that aren’t necessarily true? Identifying these details helps you later on in the process.
At this point, you likely have a general idea of the problem—but in order to come up with the best solution, you need to dig deeper.
During the research process, collect information relating to the problem, including data, statistics, historical project information, team input, and more. Make sure you gather information from a variety of sources, especially if those sources go against your personal ideas about what the problem is or how to solve it.
Gathering varied information is essential for your ability to apply the critical thinking process. If you don’t get enough information, your ability to make a final decision will be skewed. Remember that critical thinking is about helping you identify the objective best conclusion. You aren’t going with your gut—you’re doing research to find the best option
3. Determine data relevance
Just as it’s important to gather a variety of information, it is also important to determine how relevant the different information sources are. After all, just because there is data doesn’t mean it’s relevant.
Once you’ve gathered all of the information, sift through the noise and identify what information is relevant and what information isn’t. Synthesizing all of this information and establishing significance helps you weigh different data sources and come to the best conclusion later on in the critical thinking process.
To determine data relevance, ask yourself:
How reliable is this information?
How significant is this information?
Is this information outdated? Is it specialized in a specific field?
4. Ask questions
One of the most useful parts of the critical thinking process is coming to a decision without bias. In order to do so, you need to take a step back from the process and challenge the assumptions you’re making.
We all have bias—and that isn’t necessarily a bad thing. Unconscious biases (also known as cognitive biases) often serve as mental shortcuts to simplify problem solving and aid decision making. But even when biases aren’t inherently bad, you must be aware of your biases in order to put them aside when necessary.
Before coming to a solution, ask yourself:
Am I making any assumptions about this information?
Are there additional variables I haven’t considered?
Have I evaluated the information from every perspective?
Are there any viewpoints I missed?
5. Identify the best solution
Finally, you’re ready to come to a conclusion. To identify the best solution, draw connections between causes and effects. Use the facts you’ve gathered to evaluate the most objective conclusion.
Keep in mind that there may be more than one solution. Often, the problems you’re facing are complex and intricate. The critical thinking process doesn’t necessarily lead to a cut-and-dry solution—instead, the process helps you understand the different variables at play so you can make an informed decision.
6. Present your solution
Communication is a key skill for critical thinkers. It isn’t enough to think for yourself—you also need to share your conclusion with other project stakeholders. If there are multiple solutions, present them all. There may be a case where you implement one solution, then test to see if it works before implementing another solution.
7. Analyze your decision
The seven-step critical thinking process yields a result—and you then need to put that solution into place. After you’ve implemented your decision, evaluate whether or not it was effective. Did it solve the initial problem? What lessons—whether positive or negative—can you learn from this experience to improve your critical thinking for next time?
Depending on how your team shares information, consider documenting lessons learned in a central source of truth. That way, team members that are making similar or related decisions in the future can understand why you made the decision you made and what the outcome was.
Example of critical thinking in the workplace
Imagine you work in user experience design (UX). Your team is focused on pricing and packaging and ensuring customers have a clear understanding of the different services your company offers. Here’s how to apply the critical thinking process in the workplace in seven steps:
Start by identifying the problem
Your current pricing page isn’t performing as well as you want. You’ve heard from customers that your services aren’t clear, and that the page doesn’t answer the questions they have. This page is really important for your company, since it’s where your customers sign up for your service. You and your team have a few theories about why your current page isn’t performing well, but you decide to apply the critical thinking process to ensure you come to the best decision for the page.
Gather information about how the problem started
Part of identifying the problem includes understanding how the problem started. The pricing and packaging page is important—so when your team initially designed the page, they certainly put a lot of thought into it. Before you begin researching how to improve the page, ask yourself:
Why did you design the pricing page the way you did?
Which stakeholders need to be involved in the decision making process?
Where are users getting stuck on the page?
Are any features currently working?
Then, you research
In addition to understanding the history of the pricing and packaging page, it’s important to understand what works well. Part of this research means taking a look at what your competitor’s pricing pages look like.
How have our competitors set up their pricing pages?
Are there any pricing page best practices?
How does color, positioning, and animation impact navigation?
Are there any standard page layouts customers expect to see?
Organize and analyze information
You’ve gathered all of the information you need—now you need to organize and analyze it. What trends, if any, are you noticing? Is there any particularly relevant or important information that you have to consider?
Ask open-ended questions to reduce bias
In the case of critical thinking, it’s important to address and set bias aside as much as possible. Ask yourself:
Is there anything I’m missing?
Have I connected with the right stakeholders?
Are there any other viewpoints I should consider?
Determine the best solution for your team
You now have all of the information you need to design the best pricing page. Depending on the complexity of the design, you may want to design a few options to present to a small group of customers or A/B test on the live website.
Present your solution to stakeholders
Critical thinking can help you in every element of your life, but in the workplace, you must also involve key project stakeholders . Stakeholders help you determine next steps, like whether you’ll A/B test the page first. Depending on the complexity of the issue, consider hosting a meeting or sharing a status report to get everyone on the same page.
Analyze the results
No process is complete without evaluating the results. Once the new page has been live for some time, evaluate whether it did better than the previous page. What worked? What didn’t? This also helps you make better critical decisions later on.
Critical thinking takes time to build, but with effort and patience you can apply an unbiased, analytical mind to any situation. Critical thinking makes up one of many soft skills that makes you an effective team member, manager, and worker.

Thinking and Analysis
Critical thinking skills.
The essence of the independent mind lies not in what it thinks, but in how it thinks. —Christopher Hitchens, author and journalist
By the end of this section, you will be able to:
- Define critical thinking
- Describe the role that logic plays in critical thinking
- Describe how critical thinking skills can be used to problem-solve
- Describe how critical thinking skills can be used to evaluate information
- Identify strategies for developing yourself as a critical thinker
Thinking comes naturally. You don’t have to make it happen—it just does. But you can make it happen in different ways. For example, you can think positively or negatively. You can think with “heart” and you can think with rational judgment. You can also think strategically and analytically, and mathematically and scientifically. These are a few of multiple ways in which the mind can process thought.
What are some forms of thinking you use? When do you use them, and why?
As a college student, you are tasked with engaging and expanding your thinking skills. One of the most important of these skills is critical thinking. Critical thinking is important because it relates to nearly all tasks, situations, topics, careers, environments, challenges, and opportunities. It’s a “domain-general” thinking skill—not a thinking skill that’s reserved for a one subject alone or restricted to a particular subject area.
Great leaders have highly attuned critical thinking skills, and you can, too. In fact, you probably have a lot of these skills already. Of all your thinking skills, critical thinking may have the greatest value.
What Is Critical Thinking?
Critical thinking is clear, reasonable, reflective thinking focused on deciding what to believe or do. It means asking probing questions like, “How do we know?” or “Is this true in every case or just in this instance?” It involves being skeptical and challenging assumptions, rather than simply memorizing facts or blindly accepting what you hear or read.
Imagine, for example, that you’re reading a history textbook. You wonder who wrote it and why, because you detect certain biases in the writing. You find that the author has a limited scope of research focused only on a particular group within a population. In this case, your critical thinking reveals that there are “other sides to the story.”
Who are critical thinkers, and what characteristics do they have in common? Critical thinkers are usually curious and reflective people. They like to explore and probe new areas and seek knowledge, clarification, and new solutions. They ask pertinent questions, evaluate statements and arguments, and they distinguish between facts and opinion. They are also willing to examine their own beliefs, possessing a manner of humility that allows them to admit lack of knowledge or understanding when needed. They are open to changing their mind. Perhaps most of all, they actively enjoy learning, and seeking new knowledge is a lifelong pursuit.
This may well be you!
No matter where you are on the road to being a critical thinker, you can always more fully develop and finely tune your skills. Doing so will help you develop more balanced arguments, express yourself clearly, read critically, and glean important information efficiently. Critical thinking skills will help you in any profession or any circumstance of life, from science to art to business to teaching. With critical thinking, you become a clearer thinker and problem solver.
The following video, from Lawrence Bland, presents the major concepts and benefits of critical thinking.

Critical Thinking and Logic
Critical thinking is fundamentally a process of questioning information and data. You may question the information you read in a textbook, or you may question what a politician or a professor or a classmate says. You can also question a commonly-held belief or a new idea. With critical thinking, anything and everything is subject to question and examination for the purpose of logically constructing reasoned perspectives.
What Is Logic, and Why Is It Important in Critical Thinking?
The word logic comes from the Ancient Greek logike , referring to the science or art of reasoning. Using logic, a person evaluates arguments and reasoning and strives to distinguish between good and bad reasoning, or between truth and falsehood. Using logic, you can evaluate ideas or claims people make, make good decisions, and form sound beliefs about the world. 
Questions of Logic in Critical Thinking
Let’s use a simple example of applying logic to a critical-thinking situation. In this hypothetical scenario, a man has a PhD in political science, and he works as a professor at a local college. His wife works at the college, too. They have three young children in the local school system, and their family is well known in the community. The man is now running for political office. Are his credentials and experience sufficient for entering public office? Will he be effective in the political office? Some voters might believe that his personal life and current job, on the surface, suggest he will do well in the position, and they will vote for him. In truth, the characteristics described don’t guarantee that the man will do a good job. The information is somewhat irrelevant. What else might you want to know? How about whether the man had already held a political office and done a good job? In this case, we want to ask, How much information is adequate in order to make a decision based on logic instead of assumptions?
The following questions, presented in Figure 1, below, are ones you may apply to formulating a logical, reasoned perspective in the above scenario or any other situation:
- What’s happening? Gather the basic information and begin to think of questions.
- Why is it important? Ask yourself why it’s significant and whether or not you agree.
- What don’t I see? Is there anything important missing?
- How do I know? Ask yourself where the information came from and how it was constructed.
- Who is saying it? What’s the position of the speaker and what is influencing them?
- What else? What if? What other ideas exist and are there other possibilities?
Problem-Solving with Critical Thinking
For most people, a typical day is filled with critical thinking and problem-solving challenges. In fact, critical thinking and problem-solving go hand-in-hand. They both refer to using knowledge, facts, and data to solve problems effectively. But with problem-solving, you are specifically identifying, selecting, and defending your solution. Below are some examples of using critical thinking to problem-solve:
- Your roommate was upset and said some unkind words to you, which put a crimp in the relationship. You try to see through the angry behaviors to determine how you might best support the roommate and help bring the relationship back to a comfortable spot.
- Your campus club has been languishing on account of lack of participation and funds. The new club president, though, is a marketing major and has identified some strategies to interest students in joining and supporting the club. Implementation is forthcoming.
- Your final art class project challenges you to conceptualize form in new ways. On the last day of class when students present their projects, you describe the techniques you used to fulfill the assignment. You explain why and how you selected that approach.
- Your math teacher sees that the class is not quite grasping a concept. She uses clever questioning to dispel anxiety and guide you to new understanding of the concept.
- You have a job interview for a position that you feel you are only partially qualified for, although you really want the job and you are excited about the prospects. You analyze how you will explain your skills and experiences in a way to show that you are a good match for the prospective employer.
- You are doing well in college, and most of your college and living expenses are covered. But there are some gaps between what you want and what you feel you can afford. You analyze your income, savings, and budget to better calculate what you will need to stay in college and maintain your desired level of spending.
Problem-Solving Action Checklist
Problem-solving can be an efficient and rewarding process, especially if you are organized and mindful of critical steps and strategies. Remember, too, to assume the attributes of a good critical thinker. If you are curious, reflective, knowledge-seeking, open to change, probing, organized, and ethical, your challenge or problem will be less of a hurdle, and you’ll be in a good position to find intelligent solutions.
Evaluating Information with Critical Thinking
Evaluating information can be one of the most complex tasks you will be faced with in college. But if you utilize the following four strategies, you will be well on your way to success:
- Read for understanding by using text coding
- Examine arguments
- Clarify thinking
- Cultivate “habits of mind”
Read for Understanding Using Text Coding
When you read and take notes, use the text coding strategy . Text coding is a way of tracking your thinking while reading. It entails marking the text and recording what you are thinking either in the margins or perhaps on Post-it notes. As you make connections and ask questions in response to what you read, you monitor your comprehension and enhance your long-term understanding of the material.
With text coding, mark important arguments and key facts. Indicate where you agree and disagree or have further questions. You don’t necessarily need to read every word, but make sure you understand the concepts or the intentions behind what is written. Feel free to develop your own shorthand style when reading or taking notes. The following are a few options to consider using while coding text.
See more text coding from PBWorks and Collaborative for Teaching and Learning .
When you examine arguments or claims that an author, speaker, or other source is making, your goal is to identify and examine the hard facts. You can use the spectrum of authority strategy for this purpose. The spectrum of authority strategy assists you in identifying the “hot” end of an argument—feelings, beliefs, cultural influences, and societal influences—and the “cold” end of an argument—scientific influences. The following video explains this strategy.
When you use critical thinking to evaluate information, you need to clarify your thinking to yourself and likely to others. Doing this well is mainly a process of asking and answering probing questions, such as the logic questions discussed earlier. Design your questions to fit your needs, but be sure to cover adequate ground. What is the purpose? What question are we trying to answer? What point of view is being expressed? What assumptions are we or others making? What are the facts and data we know, and how do we know them? What are the concepts we’re working with? What are the conclusions, and do they make sense? What are the implications?
Cultivate “Habits of Mind”
“Habits of mind” are the personal commitments, values, and standards you have about the principle of good thinking. Consider your intellectual commitments, values, and standards. Do you approach problems with an open mind, a respect for truth, and an inquiring attitude? Some good habits to have when thinking critically are being receptive to having your opinions changed, having respect for others, being independent and not accepting something is true until you’ve had the time to examine the available evidence, being fair-minded, having respect for a reason, having an inquiring mind, not making assumptions, and always, especially, questioning your own conclusions—in other words, developing an intellectual work ethic. Try to work these qualities into your daily life.
Developing Yourself As a Critical Thinker
Critical thinking is a desire to seek, patience to doubt, fondness to meditate, slowness to assert, readiness to consider, carefulness to dispose and set in order; and hatred for every kind of imposture. —Francis Bacon, philosopher
Critical thinking is a fundamental skill for college students, but it should also be a lifelong pursuit. Below are additional strategies to develop yourself as a critical thinker in college and in everyday life:
- Reflect and practice : Always reflect on what you’ve learned. Is it true all the time? How did you arrive at your conclusions?
- Use wasted time : It’s certainly important to make time for relaxing, but if you find you are indulging in too much of a good thing, think about using your time more constructively. Determine when you do your best thinking and try to learn something new during that part of the day.
- Redefine the way you see things : It can be very uninteresting to always think the same way. Challenge yourself to see familiar things in new ways. Put yourself in someone else’s shoes and consider things from a different angle or perspective. If you’re trying to solve a problem, list all your concerns: what you need in order to solve it, who can help, what some possible barriers might be, etc. It’s often possible to reframe a problem as an opportunity. Try to find a solution where there seems to be none.
- Analyze the influences on your thinking and in your life : Why do you think or feel the way you do? Analyze your influences. Think about who in your life influences you. Do you feel or react a certain way because of social convention, or because you believe it is what is expected of you? Try to break out of any molds that may be constricting you.
- Express yourself : Critical thinking also involves being able to express yourself clearly. Most important in expressing yourself clearly is stating one point at a time. You might be inclined to argue every thought, but you might have greater impact if you focus just on your main arguments. This will help others to follow your thinking clearly. For more abstract ideas, assume that your audience may not understand. Provide examples, analogies, or metaphors where you can.
- Enhance your wellness : It’s easier to think critically when you take care of your mental and physical health. Try taking 10-minute activity breaks to reach 30 to 60 minutes of physical activity each day . Try taking a break between classes and walk to the coffee shop that’s farthest away. Scheduling physical activity into your day can help lower stress and increase mental alertness. Also, do your most difficult work when you have the most energy . Think about the time of day you are most effective and have the most energy. Plan to do your most difficult work during these times. And be sure to reach out for help . If you feel you need assistance with your mental or physical health, talk to a counselor or visit a doctor.
Activity: Reflect on Critical Thinking
- Apply critical thinking strategies to your life
- Think about someone you consider to be a critical thinker (friend, professor, historical figure, etc). What qualities does he/she have?
- Review some of the critical thinking strategies discussed on this page. Pick one strategy that makes sense to you. How can you apply this critical thinking technique to your academic work?
- Habits of mind are attitudes and beliefs that influence how you approach the world (i.e., inquiring attitude, open mind, respect for truth, etc). What is one habit of mind you would like to actively develop over the next year? How will you develop a daily practice to cultivate this habit?
- Write your responses in journal form, and submit according to your instructor’s guidelines.
The following text is an excerpt from an essay by Dr. Andrew Robert Baker, “Thinking Critically and Creatively.” In these paragraphs, Dr. Baker underscores the importance of critical thinking—the imperative of critical thinking, really—to improving as students, teachers, and researchers. The follow-up portion of this essay appears in the Creative Thinking section of this course.
Thinking Critically and Creatively
Critical thinking skills are perhaps the most fundamental skills involved in making judgments and solving problems. You use them every day, and you can continue improving them.
The ability to think critically about a matter—to analyze a question, situation, or problem down to its most basic parts—is what helps us evaluate the accuracy and truthfulness of statements, claims, and information we read and hear. It is the sharp knife that, when honed, separates fact from fiction, honesty from lies, and the accurate from the misleading. We all use this skill to one degree or another almost every day. For example, we use critical thinking every day as we consider the latest consumer products and why one particular product is the best among its peers. Is it a quality product because a celebrity endorses it? Because a lot of other people may have used it? Because it is made by one company versus another? Or perhaps because it is made in one country or another? These are questions representative of critical thinking.
The academic setting demands more of us in terms of critical thinking than everyday life. It demands that we evaluate information and analyze myriad issues. It is the environment where our critical thinking skills can be the difference between success and failure. In this environment we must consider information in an analytical, critical manner. We must ask questions—What is the source of this information? Is this source an expert one and what makes it so? Are there multiple perspectives to consider on an issue? Do multiple sources agree or disagree on an issue? Does quality research substantiate information or opinion? Do I have any personal biases that may affect my consideration of this information?
It is only through purposeful, frequent, intentional questioning such as this that we can sharpen our critical thinking skills and improve as students, learners and researchers.

13 Easy Steps To Improve Your Critical Thinking Skills

With the sheer volume of information that we’re bombarded with on a daily basis – and with the pervasiveness of fake news and social media bubbles – the ability to look at evidence, evaluate the trustworthiness of a source, and think critically is becoming more important than ever. This is why, for me, critical thinking is one of the most vital skills to cultivate for future success.
Critical thinking isn’t about being constantly negative or critical of everything. It’s about objectivity and having an open, inquisitive mind. To think critically is to analyze issues based on hard evidence (as opposed to personal opinions, biases, etc.) in order to build a thorough understanding of what’s really going on. And from this place of thorough understanding, you can make better decisions and solve problems more effectively.
To put it another way, critical thinking means arriving at your own carefully considered conclusions instead of taking information at face value. Here are 13 ways you can cultivate this precious skill:
1. Always vet new information with a cautious eye. Whether it’s an article someone has shared online or data that’s related to your job, always vet the information you're presented with. Good questions to ask here include, "Is this information complete and up to date?” “What evidence is being presented to support the argument?” and “Whose voice is missing here?”
2. Look at where the information has come from. Is the source trustworthy? What is their motivation for presenting this information? For example, are they trying to sell you something or get you to take a certain action (like vote for them)?

3. Consider more than one point of view. Everyone has their own opinions and motivations – even highly intelligent people making reasonable-sounding arguments have personal opinions and biases that shape their thinking. So, when someone presents you with information, consider whether there are other sides to the story.
4. Practice active listening. Listen carefully to what others are telling you, and try to build a clear picture of their perspective. Empathy is a really useful skill here since putting yourself in another person's shoes can help you understand where they're coming from and what they might want. Try to listen without judgment – remember, critical thinking is about keeping an open mind.
5. Gather additional information where needed. Whenever you identify gaps in the information or data, do your own research to fill those gaps. The next few steps will help you do this objectively…
6. Ask lots of open-ended questions. Curiosity is a key trait of critical thinkers, so channel your inner child and ask lots of "who," "what," and "why" questions.
7. Find your own reputable sources of information, such as established news sites, nonprofit organizations, and education institutes. Try to avoid anonymous sources or sources with an ax to grind or a product to sell. Also, be sure to check when the information was published. An older source may be unintentionally offering up wrong information just because events have moved on since it was published; corroborate the info with a more recent source.
8. Try not to get your news from social media. And if you do see something on social media that grabs your interest, check the accuracy of the story (via reputable sources of information, as above) before you share it.
9. Learn to spot fake news. It's not always easy to spot false or misleading content, but a good rule of thumb is to look at the language, emotion, and tone of the piece. Is it using emotionally charged language, for instance, and trying to get you to feel a certain way? Also, look at the sources of facts, figures, images, and quotes. A legit news story will clearly state its sources.
10. Learn to spot biased information. Like fake news, biased information may seek to appeal more to your emotions than logic and/or present a limited view of the topic. So ask yourself, “Is there more to this topic than what’s being presented here?” Do your own reading around the topic to establish the full picture.
11. Question your own biases, too. Everyone has biases, and there’s no point pretending otherwise. The trick is to think objectively about your likes and dislikes, preferences, and beliefs, and consider how these might affect your thinking.
12. Form your own opinions. Remember, critical thinking is about thinking independently. So once you’ve assessed all the information, form your own conclusions about it.
13. Continue to work on your critical thinking skills. I recommend looking at online learning platforms such as Udemy and Coursera for courses on general critical thinking skills, as well as courses on specific subjects like cognitive biases.

What are critical thinking skills?
How to develop critical thinking skills: 12 tips, how to practice critical thinking skills at work, become your own best critic.
A client requests a tight deadline on an intense project. Your childcare provider calls in sick on a day full of meetings. Payment from a contract gig is a month behind.
Your day-to-day will always have challenges, big and small. And no matter the size and urgency, they all ask you to use critical thinking to analyze the situation and arrive at the right solution.
Critical thinking includes a wide set of soft skills that encourage continuous learning, resilience , and self-reflection. The more you add to your professional toolbelt, the more equipped you’ll be to tackle whatever challenge presents itself. Here’s how to develop critical thinking, with examples explaining how to use it.
Critical thinking skills are the skills you use to analyze information, imagine scenarios holistically, and create rational solutions. It’s a type of emotional intelligence that stimulates effective problem-solving and decision-making .
When you fine-tune your critical thinking skills, you seek beyond face-value observations and knee-jerk reactions. Instead, you harvest deeper insights and string together ideas and concepts in logical, sometimes out-of-the-box , ways.
Imagine a team working on a marketing strategy for a new set of services. That team might use critical thinking to balance goals and key performance indicators , like new customer acquisition costs, average monthly sales, and net profit margins. They understand the connections between overlapping factors to build a strategy that stays within budget and attracts new sales.
Looking for ways to improve critical thinking skills? Start by brushing up on the following soft skills that fall under this umbrella:
- Analytical thinking: Approaching problems with an analytical eye includes breaking down complex issues into small chunks and examining their significance. An example could be organizing customer feedback to identify trends and improve your product offerings.
- Open-mindedness: Push past cognitive biases and be receptive to different points of view and constructive feedback . Managers and team members who keep an open mind position themselves to hear new ideas that foster innovation .
- Creative thinking: With creative thinking , you can develop several ideas to address a single problem, like brainstorming more efficient workflow best practices to boost productivity and employee morale .
- Self-reflection: Self-reflection lets you examine your thinking and assumptions to stimulate healthier collaboration and thought processes. Maybe a bad first impression created a negative anchoring bias with a new coworker. Reflecting on your own behavior stirs up empathy and improves the relationship.
- Evaluation: With evaluation skills, you tackle the pros and cons of a situation based on logic rather than emotion. When prioritizing tasks , you might be tempted to do the fun or easy ones first, but evaluating their urgency and importance can help you make better decisions.
There’s no magic method to change your thinking processes. Improvement happens with small, intentional changes to your everyday habits until a more critical approach to thinking is automatic.
Here are 12 tips for building stronger self-awareness and learning how to improve critical thinking:
1. Be cautious
There’s nothing wrong with a little bit of skepticism. One of the core principles of critical thinking is asking questions and dissecting the available information. You might surprise yourself at what you find when you stop to think before taking action.
Before making a decision, use evidence, logic, and deductive reasoning to support your own opinions or challenge ideas. It helps you and your team avoid falling prey to bad information or resistance to change .
2. Ask open-ended questions
“Yes” or “no” questions invite agreement rather than reflection. Instead, ask open-ended questions that force you to engage in analysis and rumination. Digging deeper can help you identify potential biases, uncover assumptions, and arrive at new hypotheses and possible solutions.
3. Do your research
No matter your proficiency, you can always learn more. Turning to different points of view and information is a great way to develop a comprehensive understanding of a topic and make informed decisions. You’ll prioritize reliable information rather than fall into emotional or automatic decision-making.
4. Consider several opinions
You might spend so much time on your work that it’s easy to get stuck in your own perspective, especially if you work independently on a remote team . Make an effort to reach out to colleagues to hear different ideas and thought patterns. Their input might surprise you.
If or when you disagree, remember that you and your team share a common goal. Divergent opinions are constructive, so shift the focus to finding solutions rather than defending disagreements.
5. Learn to be quiet
Active listening is the intentional practice of concentrating on a conversation partner instead of your own thoughts. It’s about paying attention to detail and letting people know you value their opinions, which can open your mind to new perspectives and thought processes.
If you’re brainstorming with your team or having a 1:1 with a coworker , listen, ask clarifying questions, and work to understand other peoples’ viewpoints. Listening to your team will help you find fallacies in arguments to improve possible solutions.
6. Schedule reflection
Whether waking up at 5 am or using a procrastination hack, scheduling time to think puts you in a growth mindset . Your mind has natural cognitive biases to help you simplify decision-making, but squashing them is key to thinking critically and finding new solutions besides the ones you might gravitate toward. Creating time and calm space in your day gives you the chance to step back and visualize the biases that impact your decision-making.
7. Cultivate curiosity
With so many demands and job responsibilities, it’s easy to seek solace in routine. But getting out of your comfort zone helps spark critical thinking and find more solutions than you usually might.
If curiosity doesn’t come naturally to you, cultivate a thirst for knowledge by reskilling and upskilling . Not only will you add a new skill to your resume , but expanding the limits of your professional knowledge might motivate you to ask more questions.
You don’t have to develop critical thinking skills exclusively in the office. Whether on your break or finding a hobby to do after work, playing strategic games or filling out crosswords can prime your brain for problem-solving.
9. Write it down
Recording your thoughts with pen and paper can lead to stronger brain activity than typing them out on a keyboard. If you’re stuck and want to think more critically about a problem, writing your ideas can help you process information more deeply.
The act of recording ideas on paper can also improve your memory . Ideas are more likely to linger in the background of your mind, leading to deeper thinking that informs your decision-making process.
10. Speak up
Take opportunities to share your opinion, even if it intimidates you. Whether at a networking event with new people or a meeting with close colleagues, try to engage with people who challenge or help you develop your ideas. Having conversations that force you to support your position encourages you to refine your argument and think critically.
11. Stay humble
Ideas and concepts aren’t the same as real-life actions. There may be such a thing as negative outcomes, but there’s no such thing as a bad idea. At the brainstorming stage , don’t be afraid to make mistakes.
Sometimes the best solutions come from off-the-wall, unorthodox decisions. Sit in your creativity , let ideas flow, and don’t be afraid to share them with your colleagues. Putting yourself in a creative mindset helps you see situations from new perspectives and arrive at innovative conclusions.
12. Embrace discomfort
Get comfortable feeling uncomfortable . It isn’t easy when others challenge your ideas, but sometimes, it’s the only way to see new perspectives and think critically.
By willingly stepping into unfamiliar territory, you foster the resilience and flexibility you need to become a better thinker. You’ll learn how to pick yourself up from failure and approach problems from fresh angles.
Thinking critically is easier said than done. To help you understand its impact (and how to use it), here are two scenarios that require critical thinking skills and provide teachable moments.
Scenario #1: Unexpected delays and budget
Imagine your team is working on producing an event. Unexpectedly, a vendor explains they’ll be a week behind on delivering materials. Then another vendor sends a quote that’s more than you can afford. Unless you develop a creative solution, the team will have to push back deadlines and go over budget, potentially costing the client’s trust.
Here’s how you could approach the situation with creative thinking:
- Analyze the situation holistically: Determine how the delayed materials and over-budget quote will impact the rest of your timeline and financial resources . That way, you can identify whether you need to build an entirely new plan with new vendors, or if it’s worth it to readjust time and resources.
- Identify your alternative options: With careful assessment, your team decides that another vendor can’t provide the same materials in a quicker time frame. You’ll need to rearrange assignment schedules to complete everything on time.
- Collaborate and adapt: Your team has an emergency meeting to rearrange your project schedule. You write down each deliverable and determine which ones you can and can’t complete by the deadline. To compensate for lost time, you rearrange your task schedule to complete everything that doesn’t need the delayed materials first, then advance as far as you can on the tasks that do.
- Check different resources: In the meantime, you scour through your contact sheet to find alternative vendors that fit your budget. Accounting helps by providing old invoices to determine which vendors have quoted less for previous jobs. After pulling all your sources, you find a vendor that fits your budget.
- Maintain open communication: You create a special Slack channel to keep everyone up to date on changes, challenges, and additional delays. Keeping an open line encourages transparency on the team’s progress and boosts everyone’s confidence.
Scenario #2: Differing opinions
A conflict arises between two team members on the best approach for a new strategy for a gaming app. One believes that small tweaks to the current content are necessary to maintain user engagement and stay within budget. The other believes a bold revamp is needed to encourage new followers and stronger sales revenue.
Here’s how critical thinking could help this conflict:
- Listen actively: Give both team members the opportunity to present their ideas free of interruption. Encourage the entire team to ask open-ended questions to more fully understand and develop each argument.
- Flex your analytical skills: After learning more about both ideas, everyone should objectively assess the benefits and drawbacks of each approach. Analyze each idea's risk, merits, and feasibility based on available data and the app’s goals and objectives.
- Identify common ground: The team discusses similarities between each approach and brainstorms ways to integrate both idea s, like making small but eye-catching modifications to existing content or using the same visual design in new media formats.
- Test new strategy: To test out the potential of a bolder strategy, the team decides to A/B test both approaches. You create a set of criteria to evenly distribute users by different demographics to analyze engagement, revenue, and customer turnover.
- Monitor and adapt: After implementing the A/B test, the team closely monitors the results of each strategy. You regroup and optimize the changes that provide stronger results after the testing. That way, all team members understand why you’re making the changes you decide to make.
You can’t think your problems away. But you can equip yourself with skills that help you move through your biggest challenges and find innovative solutions. Learning how to develop critical thinking is the start of honing an adaptable growth mindset.
Now that you have resources to increase critical thinking skills in your professional development, you can identify whether you embrace change or routine, are open or resistant to feedback, or turn to research or emotion will build self-awareness. From there, tweak and incorporate techniques to be a critical thinker when life presents you with a problem.

How to sharpen your critical thinking skills
Amy Herman ’88 trains leaders around the world in how to make tactical decisions. Here, she shares three habits that will help improve any problem-solving process.
ILLUSTRATION BY MIGUEL PORLAN
The FBI. Peace Corps. United States Postal Service. Johnson & Johnson. Georgetown University Hospital. New York City Public Schools. These are just a bite-size sample of the organizations around the world that have enlisted Amy Herman ’88 to empower employees with a vital skill: critical thinking.
The founder and president of The Art of Perception Inc., Herman takes an innovative approach to the professional development training she provides to leaders across industries. She uses artwork as a means to challenge people to change how they see things, make keener observations, and tactfully glean information from any situation to more effectively perform their jobs.
“At Lafayette, I discovered something in my liberal arts education I wouldn’t have otherwise: how powerful art is,” Herman says. “Now, I teach others how to look at art as data they’ve never seen before, ask questions, and use the power of perception to bring a fresh set of eyes to what they do every day.”
At the heart of critical thinking, Herman says, is “visual intelligence,” or the ability to gain clarity by seeing things from different perspectives. As she notes, understanding that there are multiple lenses through which a single situation can be viewed helps us make more acute assessments and better-informed decisions. Ready to see and impact the world in a new way? Here’s Herman’s advice for thinking more critically.
Make yourself uncomfortable
Falling into a daily routine is a common human experience, as it provides a sense of security. But it often causes us to miss out on new experiences that can help us grow our thought processes. Herman suggests making a daily conscious effort to either notice something new in your everyday surroundings or put yourself in an unfamiliar situation. “It could be something as small as taking a different route to work, or as big as traveling to a place where you don’t speak the language,” Herman says. “Making yourself uncomfortable strengthens your situational awareness and neuroplasticity, trains your brain to get out of a linear way of thinking, and expands your ability to adapt.”
Understand “the pertinent negative”
Herman teaches her trainees about “the pertinent negative,” the concept of noticing what’s not present in addition to what is in order to gain a fuller picture of a situation. “In medicine, the symptoms patients don’t talk about are just as, if not more, important than the ones they do talk about, and that’s critical to a doctor’s assessment,” Herman says. “When you’re looking to solve a problem at work, think about what people aren’t saying or what didn’t happen at a meeting. Ask yourself: ‘What do I know? What don’t I know? And if I had the opportunity to get one more piece of information, what would I need to know?’ It makes big challenges less daunting, and it helps you create better solutions.”
Choose your words carefully
Two words you should strike from your vocabulary, according to Herman, are “obviously” and “clearly.” Because we all view things differently, what’s clear to one person may not be so to another. “Never assume we’re all thinking about the same elephant in the room,” Herman says. “We live and work in a complex world where nothing is obvious. Instead, explain why something appears to you the way it does. Not only will that help you better understand your own perceptions, but it’ll help others gain clarity on them too. The words you use to talk to your team during a presentation, a meeting, an investigation—they matter.”

Critical thinking definition
Critical thinking, as described by Oxford Languages, is the objective analysis and evaluation of an issue in order to form a judgement.
Active and skillful approach, evaluation, assessment, synthesis, and/or evaluation of information obtained from, or made by, observation, knowledge, reflection, acumen or conversation, as a guide to belief and action, requires the critical thinking process, which is why it's often used in education and academics.
Some even may view it as a backbone of modern thought.
However, it's a skill, and skills must be trained and encouraged to be used at its full potential.
People turn up to various approaches in improving their critical thinking, like:
- Developing technical and problem-solving skills
- Engaging in more active listening
- Actively questioning their assumptions and beliefs
- Seeking out more diversity of thought
- Opening up their curiosity in an intellectual way etc.
Is critical thinking useful in writing?
Critical thinking can help in planning your paper and making it more concise, but it's not obvious at first. We carefully pinpointed some the questions you should ask yourself when boosting critical thinking in writing:
- What information should be included?
- Which information resources should the author look to?
- What degree of technical knowledge should the report assume its audience has?
- What is the most effective way to show information?
- How should the report be organized?
- How should it be designed?
- What tone and level of language difficulty should the document have?
Usage of critical thinking comes down not only to the outline of your paper, it also begs the question: How can we use critical thinking solving problems in our writing's topic?
Let's say, you have a Powerpoint on how critical thinking can reduce poverty in the United States. You'll primarily have to define critical thinking for the viewers, as well as use a lot of critical thinking questions and synonyms to get them to be familiar with your methods and start the thinking process behind it.
