6 Steps for Effective Critical Thinking

On a daily basis, we face problems and situations that should be evaluated and solved, and we are challenged to understand different perspectives to think about these situations. Most of us are building our cognitive thinking based on previous similar situations or experiences. However, this may not guarantee a better solution for a problem , as our decision may be affected by emotions, non-prioritized facts, or other external influences that reflect on the final decision. Therefore, critical thinking tends to build a rational, open-mined process that depends on information and empirical evidence.

The National Council for Excellence in Critical Thinking defines critical thinking as an “intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.” The process tends to help us judge and evaluate situations based on understanding the related data, analyze it, build a clear understanding of the problem, choose the proper solution, and take actions based on the established solution.

The critical thinking process prevents our minds from jumping directly to conclusions. Instead, it guides the mind through logical steps that tend to widen the range of perspectives, accept findings, put aside personal biases, and consider reasonable possibilities. This can be achieved through six steps: knowledge, comprehension, application, analyze, synthesis, and take action. Below is a brief description of each step and how to implement them.

Step 1: Knowledge

For every problem, clear vision puts us on the right path to solve it. This step identifies the argument or the problem that needs to be solved. Questions should be asked to acquire a deep understanding about the problem. In some cases, there is no actual problem, thus no need to move forward with other steps in the critical thinking model. The questions in this stage should be open-ended to allow the chance to discuss and explore main reasons. At this stage, two main questions need to be addressed: What is the problem? And why do we need to solve it?

Step 2: Comprehension

Once the problem is identified, the next step is to understand the situation and the facts aligned with it. The data is collected about the problem using any of the research methods that can be adopted depending on the problem, the type of the data available, and the deadline required to solve it.

Step 3: Application

This step continues the previous one to complete the understanding of different facts and resources required to solve the problem by building a linkage between the information and resources. Mind maps can be used to analyze the situation, build a relation between it and the core problem, and determine the best way to move forward.

Step 4: Analyze

Once the information is collected and linkages are built between it the main problems, the situation is analyzed in order to identify the situation, the strong points, the weak points, and the challenges faced while solving the problem. The priorities are set for the main causes and determine how they can be addressed in the solution. One of the commonly used tools that can be deployed to analyze the problem and the circumstances around it is the cause effect diagram , which divides the problem from its causes and aims to identify the different causes and categorize them based on their type and impact on the problem.

Step 5: Synthesis

In this stage, once the problem is fully analyzed and all the related information is considered, a decision should be formed about how to solve the problem and the initial routes to follow to take this decision into action. If there are number of solutions, they should be evaluated and prioritized in order to find the most advantageous solution. One of the tools that contribute choosing the problem solution is the SWOT analysis that tends to identify the solution’s strength, weakness, opportunity, and threats.

Step 6: Take Action

The final step is to build an evaluation about the problem that can be put into action. The result of critical thinking should be transferred into action steps. If the decision involves a specific project or team, a plan of action could be implemented to ensure that the solution is adopted and executed as planned.

The critical thinking method can be adopted to replace emotions and perusal biases when trying to think about a situation or a problem. The time for adopting critical thinking varies based on the problem; it may take few minutes to number of days. The advantage of deploying critical thinking is that it contributes to widening our perspectives about situations and broadening our thinking possibilities. However, these steps should be translated into a plan of action that ensures that the decided resolution is well achieved and integrated between all the involved bodies.

6 Steps to better critical thinking

Rationale’s interface has been designed to provide a path for critical thinking. From gathering research, to weighing up evidence to formulating a judgement, Rationale will assist you.

Take a look at these 6 critical thinking steps with examples to demonstrate the path to better outcomes.

Step 1: ORGANISE INFORMATION We have no difficulty in locating information. The key is that the information is selected and structured appropriately. With Rationale’s grouping maps you can drag information from the web onto your workspace via the scratchpad and include colour, hyperlinks and images. The structured, pyramid like maps provide a guide for students to structure the information in such a way that reveals the connections between the main topic and its various themes or categories.

Step 2: STRUCTURE REASONING Many people provide opinions but rarely provide supporting reasons for their view. Rationale’s reasoning maps encourage people to support their responses and to consider different opinions. It uses colour conventions to display reasoning – green for reasons, red for objections and orange for rebuttals. It also includes indicator or connecting words so that the relationship between statements is clearly understood.

Step 3: CONSIDER EVIDENCE A test of a solid argument is how good the evidence is that underpins the claims. Rationale’s basis boxes provide a means to identify the basis upon which a statement is given. The icons provide a visual guide as to the range of research utilised and the strength of the evidence that is provided.

Step 4: IDENTIFY ASSUMPTIONS We often talk about analysing arguments. This can mean a few things including looking at the logical structure of the argument to ensure it is valid or well formed and also identifying assumptions or co premises. For those who require higher levels of analysis, Rationale provides the analysis map format to show the relationships between main premises and co premises.

Step 5: EVALUATE ARGUMENTS Once arguments for and against an issue have been logically structured, they need to be evaluated. Rationale provides a visual guide for the evaluation of claims and evidence – the stronger the colour, the stronger the argument while icons designate acceptable or rejected claims. While learning this process of evaluating arguments, the colour and icons provide immediate undertanding and communication of the conclusion.

Step 6: COMMUNICATE CONCLUSION Presenting ideas orally or in writing is crucial and is often the distinguishing feature between good results and average ones. Rationale has essay and letter writing templates to build skills and confidence. Templates provide instruction and generation of prose. When exported, there is a structured essay plan with detailed instructions to assist understanding of clear and systematic prose.

Critical Thinking

Developing the right mindset and skills.

Written 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. [1]

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.

Logical Thinking

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.

Self-Awareness

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:

Gather Information

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.

The basic process of critical thinking, improving your critical thinking skills, critical thinking and social media, critical thinking and the mainstream media, critical thinking and improving mental health, critical thinking in everyday life.

Critical thinking is the foundation of rationality and independent thought.

Developing this vital skill allows a person to not only see the world through clearer eyes, but to reach reasonable conclusions and make better decisions in their life .

It is one’s ability to think objectively without the influence of one’s own biases, prejudices, personal feelings, or opinions and come to a conclusion solely on factual, objective information.

A critical thinker is someone who can draw logical connections between actions and reactions, troubleshoot and systematically solve problems, and detect common mistakes in the reasoning of arguments – including their own.

The critical thinker is a person who is more easily able to understand themselves and their motivations for feeling and believing the things that they do.

They are also willing and able to entertain and understand multiple perspectives of an argument before making their own decisions.

Many people mistake critical thinking for the collection of knowledge. A degree does not necessarily mean that the person is a good critical thinker, though many people credit college education with developing their critical thinking skills.

A critical thinker is more agile. They tend to use the knowledge they possess to identify weaknesses in their reasoning and seek out new information that will allow them to make a more informed decision.

They are typically not afraid to ask questions or change their opinions when presented with new information.

Another common misconception is that critical thinking means to be overly skeptical or critical of what other people are saying or doing. Though it can be used to tear through weak arguments or bad reasoning, it can also be used to help persuade and build in a more positive direction.

Critical thinking is a valuable tool for personal or professional success because it helps us make sounder decisions from a rational place rather than acting on how we feel.

There are those – often artists and creative types – who feel deeply that placing rules and restrictions on one’s thinking limits their ability to be creative. That isn’t necessarily so.

In fact, critical thinking pairs well with creative thinking when trying to build a large or long-term project. If it is not well ordered and organized, a project or idea can be broken to pieces from the stress when it finally reaches a real world application.

The guidelines and rules of critical thinking can serve to guide our thoughts. If we know, by virtue of the knowledge that we have, that some facet of a project won’t work out, we can deduce that we need a better solution rather than relying on what we know or seeking a shortcut.

That leads a creator down different roads that they may not have previously considered before.

People perceive and think of the world in different ways. The following steps present the basic process of critical thinking, but should really only be used as a guideline and a place to start developing or improving on those skills.

Analysis and problem solving is best done in a methodical way, so you can develop a habit to build on and hone further.

It can also help you identify any weaker points in your thinking so you can work on developing those further too.

1. Identification and clarification.

Identification and clarification of the problem or subject gives us our place to start. You can’t solve a problem or scrutinize information unless you identify what you are trying to accomplish.

Examples of identification and clarification may include:

– Is this news headline or article biased? The news and media, particularly opinion-editorials, will often be written from a perspective that is not neutral.

– Is this factoid presented in a way that is meant to evoke emotion? Advertisers and influencers may write or speak in such a way as to evoke an emotional reaction to influence the way you think about what you are viewing.

– Is this social media meme honestly representing the subject matter? Almost everything shared around on social media will have some emotional bias to it, often purposefully put there to play on fear or anger.

– Is this problem that I’m looking at the actual problem or is it something else? The problem in front of you isn’t always the actual problem. The low morale in a workplace may not be because the job is bad, but because management is bad. Things aren’t always what they seem on the surface.

2. Investigation and research.

Once you’ve identified what you’re actually looking for, it’s time to research and investigate the components of the thing that you are scrutinizing. How do you go about that?

– Identify the source. Ideally, you want to track the piece of information back to where it came from to see how it originated.

Is it just a problem that developed? Is it a piece of information that’s been carefully crafted by a think-tank or marketing firm with an agenda? Does anyone stand to gain anything by you or other people believing it?

In regard to personal interactions, it’s always worthwhile to double-check on their claims. Trust, but verify.

– Look for third-party information on the claim. Ideally, you want to look for neutral, unbiased third-party information about the claim.

Where can you find that? Articles from the Associated Press, Reuters, and the BBC are a good start. Websites that are from .gov and .edu domains are usually valid.

The blogs of attorneys and doctors can be valuable as well, because reputation is so important in their respective fields so they tend to scrutinize what represents them well.

Legitimate online journals and Google Scholar can be used to find studies for further information.

Any language that includes emotional appeals in the writing or material is not likely to be a good source.

3. Identify bias, either personal or external.

Identifying outside bias is much easier than identifying personal bias.

A person really needs to be in tune with who they are, what they believe, and why they believe it to be able to identify their own bias in their perceptions of a piece of information or a problem.

Again, we come back to emotions. How do you feel about the piece of information or problem? Does it invoke anger? Sadness? Excitement? Hopefulness? Why does it invoke those emotions? And are those emotions causing you to not see the other angles of the situation?

Emotion is a quick, easy way to tell that you may be influenced by your own beliefs rather than objective facts.

Of course, there are some things that we are so raw about that it is impossible to be completely objective, and that’s okay.

Just being aware of the bias and striving to not use it as a basis of your examination, judgment, and decision making will give you a much greater edge in your critical thinking.

4. Inference and conclusion.

Data and information does not always come with a clean, foregone conclusion attached to it. Most of the time, you will need to draw your own conclusions from the information that is available.

The more valid information you can gather before drawing your conclusion, the more likely it is that your conclusion will land in the general area of correct. Particular details may change the overall perspective of a piece of data.

As an example, let’s say a business produces 1,000 widgets in the course of a production run. You can’t infer if that is a lot of widgets or not.

Maybe they need to produce a million for their order, in which case it’s not that many widgets. Maybe they had machinery that broke down where they were only able to produce half of their widget capacity for the production run.

It may be a lot, it may not be. New factual information and details will change your perspective on the business’s widget production.

5. Determining relevance of information.

There is a lot of information out there. The internet is packed with over 1 billion websites where you can find a plethora of information on just about everything.

Too much information can be a serious problem. The internet is also polluted with a lot of biased and misinformation.

Even if your information is factually correct, it doesn’t necessarily mean that it is relevant to whatever data, information, or situation you are trying to analyze. It may turn out that there are only a handful of data points that are important to the situation.

Let’s build a bit more on the widget example. Is 1,000 widgets an efficient production run for the company? The business has 30 employees. But wait, how many employees are actually responsible for producing the widgets?

What about management? Accounting? Marketing? Research and Development? It doesn’t matter if the company has 30 employees if only 5 of them are producing the necessary widgets.

The number of total employees is irrelevant information, though factually correct, while the quantity that are producing the widgets is relevant.

1. Ask more relevant questions. Far too often we force ourselves into a narrow path of thinking based on the information that is given to us.

However, there are times when that path would be much broader if we only had a greater perspective of the overall situation.

Asking more relevant questions allows you to gather more information, discern what is important and not, and allows you to make more informed decisions.

2. Question your basic assumptions. Do you just know a certain thing to be true? What do you believe in as an adamant truth? Something you believe in wholeheartedly?

Question it. Look into the counterarguments from experts and other people about those assumptions.

Can you adequately justify what you believe past how you feel or what you believe? Can you shore up those adamant beliefs with facts and truth?

3. Identify your personal biases and prejudices. What do you hate? What upsets you? What makes you angry, sad, or afraid?

Identifying these emotional points in yourself can help you when you are confronted with those situations, because sometimes our emotions do not line up with the reality that we are perceiving. This is particularly true with opinion-editorials, social media, and the news.

4. Examine other conclusions. There are a lot of people in the world who have already blazed trails that you may be trying to walk down. You don’t need to blaze the trail again if you have a goal you are pursuing and need to find your way.

By all means, incorporate your own ideas and pick your own path, but do research about how other people accomplished similar goals.

It can provide additional inspiration thanks to an outside perspective that you may not have otherwise considered. Also, be certain to explore how they reached their ultimate conclusion and destination.

5. Understand that no one can think critically all of the time. Even the most stalwart of critical thinkers is going to have momentary lapses of judgment or understanding.

You’re not going to maintain a veneer of perfection in your critical thinking. No one does or can. It’s just impossible.

That’s why it is always a good idea to not only double check your own sources, but those of other people, even if they are someone you admire for their perspective or critical thinking skills.

Mistakes happen. Trust, but verify.

6. Don’t lose yourself in the research and thoughts of others. In doing your research, you do want to make sure that you are thinking for yourself .

If something seems off or doesn’t line up with your own experience, it’s worth making a note of it and exploring it further. You may find that you have knowledge of your own that changes context or perspective that can give you additional clarity.

Don’t get so caught up in the work that you forget about your own knowledge and experience.

7. Practice continued curiosity in more things. Curiosity is a fundamental part of critical thinking. It’s the reason we examine the ‘why’ of a bit of knowledge or experience.

Make curiosity and wonder a regular part of your existence. If something seems interesting to you, do some research on it.

Better yet, even if something doesn’t seem interesting to you, do some additional research on it. That will help you build a broad perspective and body of knowledge to draw from.

8. Never assume you’re right. In assuming that you are right about a particular thing, you miss out on the opportunity to learn something new from someone who might have a different perspective or information you have not considered.

It’s okay to be confident in what you know, but it is worthwhile to listen to additional perspectives for more facts and context that you may not possess.

People who assume they are right rarely take the time to really listen to other people, instead defaulting to what they think they know and closing themselves off.

Social media is a pervasive part of the everyday lives of many people. Nearly 3 billion people around the world are using social media as a means to connect, share information and news, and exchange ideas every day.

The problem with that is that people with similar ideas tend to flock together. The algorithms that social media websites utilize look at your interests, what you are commenting about, what you are liking and sharing, and serve you up more information about the things that you like.

That can be good in finding things that are relevant to your interest, but it can be bad if all you’re doing is shouting into an echo chamber.

You can very quickly find yourself being presented with news and information that is crafted and tailored specifically to people with your interests and perspectives.

On the one hand, it can be a good thing to be around other people with similar interests. On the other, it can reinforce negative and incorrect perceptions about the world, fanning the flames of ignorance, anxiety, fear, and anger.

Social media is a fantastic tool for keeping in touch and seeking out new information, but one must be careful to treat everything they read with skepticism.

People with an agenda may craft emotional appeals or create content that is slanted to evoke an impulsive emotional reaction out of the viewer.

Misinformation spreads like wildfire because it’s often emotional speculation, which resonates with people and causes them to hit those like and share buttons.

A good rule of thumb is to check the veracity and accuracy of any story or claim that evokes an emotional reaction out of you.

Angry? Disgusted? Scared? Research it. Someone with an agenda likely crafted it that way to capitalize on your emotions and use them against you.

The critical examination of these feelings and their sources can bring a lot more peace and calmness to your life.

The internet, blogging, and social media has forced mainstream media into a questionable place.

The internet and social media move at a tremendous pace. Old school mainstream media and news sources did not.

It used to be that there were only one or two new bulletins a day. It gave the news plenty of time to research stories, dig up the truth, eliminate fabrications or misconceptions, and present a fairly unbiased story.

Now, the mainstream media needs to compete with the instant gratification for information that the internet provides. Consumers of news information are going to go where they can access it immediately.

As a result, you have social media or comment sections on news sites blowing up about events that have happened, or that are currently in progress, before anyone has had any time to actually confirm what the truth is.

Many news organizations have also introduced entertainment factors into their shows, particularly with pundits and personality hosts who are able to generate an audience and draw a crowd.

Far too many people are equating the skewed opinions of their favorite hosts or pundits with what is factual, because they rely on emotional appeal to connect and maintain a relationship with their audience.

None of it should be taken at face value because it’s impossible to know just how truthful and honest that source of information is without taking the time to research their claims. Instead, use their information to guide your own research and reading.

A good indicator that you’re being influenced is the use of weasel words and speculative questioning. “Could this be happening…?” “What exactly is going on here…?” “This circumstance may be occurring…” “What don’t they want you to know?”

Good news reporting is direct, factual, and unemotional.

Improving one’s critical thinking can serve as an effective tool to help improve one’s emotional and mental health.

There are many mental health issues that stem from emotions that are either allowed to run uncontrolled or are running out of control on their own.

This is not to suggest that all emotions are controllable or that a person can just think themselves to mental wellness. That’s not how it usually works.

However, there are times when a person can lessen the effects of mental or emotional unwellness with the help of critical thinking.

Consider a person with anxiety. The news and social media are chock full of fearful information, often that is written or presented in such a way to capitalize on the emotion of the consumer.

That person with anxiety may make their own anxiety worse by constantly keeping themselves embroiled in the drama and half-truths that are rife throughout media sources.

There’s always something to be fearful of, because fear and insecurity keeps people tuning in for more information about things that may or may not affect them.

In a similar way, there are many people with depression who find solace in dark humor, sad music, or depression related memes and content.

The more depressing and sad things a person exposes themselves to, the more it is going to drag down their own mood and perceptions of the world, which in turn fuels and makes the depression worse.

It is well-known and accepted that social media can negatively impact mental health in particular situations.

However, it is also a way for people to solidly connect with one another that may otherwise have a hard time finding like-minded people. It’s not all negative, but it’s not all positive either.

Critical thinking is a powerful tool that can help a person greatly in their pursuit of peace, happiness, and a calm life, but it is not a natural skill.

Few people are inherently blessed with critical thinking capabilities, while others need to practice and train their mind to embrace the related concepts.

Adding it to your mental toolbox can help you avoid certain pitfalls of life and not be unnecessarily disturbed by what goes on in the world.

It doesn’t matter what kind of person you are. Critical thinking is good and beneficial for everyone.

What is critical thinking?

5 characteristics of critical thinking, what are critical thinking skills, and why are they important, 6 key critical thinking skills, critical thinking example in real-life, 13 ways to start thinking critically.

Whether you’re aiming to improve your performance at work or simply trying to live a more fulfilling life , you’ll need a variety of hard and soft skills to move the needle. Some skills come naturally to some people, while others need to develop them actively.

One of these skills is critical thinking. But critical thinking itself is made up of several types of skills that contribute to solving problems more effectively.

Let’s explore the different types of critical thinking skills and how you can start improving them to level up your career.

Critical thinking is the ability to analyze facts objectively and form a judgment. It is a form of emotional intelligence .

Someone with critical thinking skills can think clearly and rationally when the situation demands it. It allows them to perform problem-solving and decision-making more effectively. 

As a result, you can look further than what you see at face value. You’re able to analyze what you see from a situation and gain some insight that goes further than what’s obvious to anyone from the outside.

Critical thinking also requires being able to understand the logical connection between two or more ideas or concepts. For example, a team working on a company’s pricing strategy needs to think critically about several concepts. 

Both the marketing and sales teams must work together. They need to analyze how to maximize sales. But they need to do so while also meeting profit goals. It’s important to understand the logical connection between sales strategy and marketing logistics. It’s the only way to get a good outcome.

Critical thinking is different from creative thinking . Creative thinking is the ability to generate brand new, innovative ideas. On the other hand, critical thinking requires you to carefully and logically analyze what information is given to you. Both are important to maximize results in any given situation.

What defines critical thinking? How does it affect the decision-making process? Here are five characteristics that make up the ability to think critically.

1. Dispositions

Critical thinkers have specific traits that allow them to think the way they do. Some people are predisposed to these traits, while others need to develop them actively.

Some of these dispositions include:

• Open-mindedness
• Respecting evidence and reasoning
• Being able to consider different perspectives and points of view: in other words, having cognitive flexibility
• Not being stuck in one position
• Clarity and precision

2. Argument

Good critical thinkers need to make solid arguments. 

An argument is making a statement aided by supporting evidence. It’s important to use well thought-out arguments when you’re in a constructive conflict . When analyzing a situation critically, you’ll need to make several arguments in your own mind to come to a judgment. 

3. Reasoning

In addition to arguments, critical thinking also requires inferring conclusions. From the facts and arguments presented to you, you need to use reasoning skills to come to a logical conclusion. 

This conclusion will determine the best course of action to take.

4. Criteria

Critical thinking is sometimes a matter of discerning truth from fiction. Not all facts presented to you may have the same level of truth. Certain conditions need to be met for something to be considered believable, and a critical thinker needs to be able to understand that.

5. Metacognition

Metacognition is the ability to think about your own thinking. Critical thinkers should be able to analyze their thoughts so that they can judge whether or not they’ve thought everything through. This helps them come up with better hypotheses.

The critical thinking skills definition is: soft skills that help you in the critical thinking process. Developing these skills can improve your ability to think critically.

Critical thinking skills are considered one of many durable skills in the workplace . Many of these are soft skills that are also useful in other situations.

According to research by America Succeeds, critical thinking is in the top five most requested durable skills in job postings. Those top five durable skills get requested 2.6x more often than the top five hard skills. This goes to show that soft skills like critical thinking skills are in demand in the workplace.

Critical thinking skills are important for several reasons. These include helping you work independently and solve problems . Not all positions require ongoing critical thinking. But, those skills definitely matter to anyone who wants to uplevel their career. And even the most easygoing positions require at least some level of critical thinking skills.

For example, working as an accountant can be straightforward in most cases. But it may require critical thinking skills. For instance, what if certain expenses aren’t easily distributed in simple categories? Without critical thinking skills, an accountant will struggle to work independently and solve problems on their own.

Critical thinking abilities also matter in everyday life. Having a foundation for critical thinking can help you analyze several possible solutions for problems that pop up in the home. It can also help you:

• Analyze different viewpoints
• Come up with the best solution for complex problems
• Become a better learner

The key critical thinking skills are identifying biases, inference, research, identification, curiosity, and judging relevance.

Let’s explore these six critical thinking skills you should learn and why they’re so important to the critical thinking process.

1. Identifying biases

This critical thinking skill is necessary for metacognition, which is the fifth characteristic of critical thinking. It involves knowing when others have a cognitive bias and when you have one yourself.

Biases can influence how someone understands the facts presented to them. But when you’re aware of those biases, you can question yourself on those biases and consider other points of view.

Identifying biases is especially important for people who make hiring decisions. That’s because biases against groups of minorities can lead to inequalities in the workplace when not identified. 

For example, imagine a hiring manager comparing two resumes. Their gut feeling could guide them to discount one of the resumes due to a bias against the opposite gender. But let’s say this hiring manager realizes they have this bias. They can then question themselves on whether or not this bias is influencing their judgment. 

2. Inference

Inference is the ability to draw conclusions based on the information you have. Without inference, it can be difficult to take action once you’ve analyzed the facts presented to you. Processing information is key to coming up with a reasoned judgment.

For example, let’s go back to the accountant struggling to assign the correct category to a business expense. They can analyze other similar situations and infer the most logical category based on that information.

3. Research

Before you analyze facts and infer a conclusion, you need to find out what those facts are. Researching skills allow you to discover facts and figures to make an argument.

Not all situations will have the required information available to you. Researching skills are necessary to dig into a situation and gather the information you need to think critically.

Some situations don’t require further research. For example, a first responder who arrives on the scene of an automobile accident won’t perform further research. They’ll have to analyze what they see in front of them and decide which injuries are the most urgent to care for. 

On the other hand, someone performing a market analysis will need to research competitors and gather information before coming up with an opinion. 

4. Identification

Identification is different from inference and research. It involves being able to identify a problem but also what’s influencing that problem.

In short, identification is necessary for someone to realize that they need to think critically about something. Without proper identification skills, it will be difficult for someone to know when it’s time to analyze a situation. 

For example, let’s say you’re entering numbers in a spreadsheet. The numbers aren’t coming out as they usually do. Without identification skills, you could easily keep going without realizing there’s an issue. But when you identify what’s going on, you can see that something is broken in the spreadsheet’s formula.

Only once you identify the fact that the formula is broken can you start analyzing what’s going on to solve the issue.

5. Curiosity

Don’t be afraid to question everything and explore what you’re curious about. That’s because intellectual curiosity is a valuable skill, especially when it comes to critical thinking.

One way to practice curiosity is to adopt a beginner’s mindset . When you come into every situation with the mindset of a beginner, you’re able to keep an open mind. You’ll be able to perceive things you may not have noticed when keeping your mind closed.

6. Judging relevance

Not all information is equally pertinent. In order to make a critical judgment, it’s important to be able to judge the relevance of the information you have.

Take, for instance, basic online researching skills. You have access to a plethora of information on virtually every topic imaginable. But performing online research requires you to constantly judge the relevance of what you see. 

Without judging relevance, you’d spend too much time on details that don’t matter as much for the final desired outcome. But when you’re able to discern what’s most pertinent, you can give that information more weight as you’re thinking critically.

So what would critical thinking skills look like in a real-life situation?

Let’s imagine you’re working in software quality assurance (QA) as a team lead. But every time your team needs to enter bug regression, everyone gets bottlenecked because you must manually populate the spreadsheet used for the regression. While you do this task, your team cannot be productive without you.

This process happens once a week and easily wastes half an hour for each team member.

First, you must identify what’s going on. The team gets bottlenecked because only you, as the team lead, can access the information required to fill in the regression spreadsheet.

Next, you can research information. You can inquire to higher-ups about the reason why only you have access to this information. You can also speak to other teams about what potential solutions they’ve come up with to solve this problem.

Once you’ve done your research, it’s time to analyze the information and judge relevance. Some teams have solutions that don’t apply to you, so that information isn’t relevant anymore. 

Figure out if there are any personal biases before you analyze your information. 

For example, it’s possible that you don’t get along with one of the other team leads. As a result, you could discount the information they’ve given you. But by identifying this bias, you can look past your personal opinion of this person and see how valuable their solution is.

Based on what you’ve analyzed, it’s time to brainstorm and come up with a solution. You realize that creating a simple, automated script will save your team’s time. And it will do so without consuming too many resources from the engineering department.

Next, present your solution to your manager. Explain how you came to this conclusion. 

Now, let’s say your spreadsheet automation solution is approved. It’s important to go back and analyze what happens after implementing the solution. But only do this once the spreadsheet has been in place for long enough to gather plenty of information. 

Here’s an example. You could realize that the solution did solve the bottleneck. But, the script also slows down the spreadsheet and makes it difficult to work with. This would require you to go back to the drawing board and start the process all over again.

Want to start improving your own critical thinking skill sets? Here’s how you can improve critical thinking skills using 13 techniques:

How Should We Think: The 6 Stages Of Critical Thinking

Photo:Graph: Paul Ratner. Credit: Elder / Paul

Most of us over the last year have had our strongest will tested and our endurance pushed to its limit. But it hasn't only been our emotions that have been getting pulled through ordeals, our minds have also been pulled like never-before, and sadly many of us have fallen for elaborate conspiracy theories without any evidence, and for other fake-news regarding the pandemic.

The key to searching for truth, even in the most extreme dilemma, is to engage in ' critical thinking '. This means that we can evaluate evidence and what people tell us objectively and reach a more accurate conclusion about a situation.

Two psychologists, Linda Elder and Richard Paul , have now devised a 6-stage-pyramid of critical thinking that lets individuals assess just how good a critical thinker they are, and therefore how they can improve their critical thinking going forward. It starts from the bottom rung ' the unreflective thinker ' and moves all the way up to ' master thinker '.

Stage One: The Unreflective Thinker

In this stage, people are pretty much automatons. They act on instinct and take what is told to them at face-value. The have high levels of prejudice and jumbled thinking or thinking that is based on very faulty logic.

It shouldn't be thought though that these people are all uneducated, as Elder and Paul state :

"It is perfectly possible for students to graduate from high school, or even college, and still be largely unreflective thinkers."

Stage Two: The Challenged Thinker

At this stage, people do actually think about issues and scenarios in some depth, they also know that logical flaws in thinking can result in very negative consequences for themselves and others. However, like the unreflective thinker, they are also affected by personal biases, though they may be able to recognise that they do possess these biases in the first-place.

In that stage, it is very hard for the individual, even if they understand that an argument is poor, to be able to specify where the flaw lies in the logic behind it. They know something isn't right, but they can't quite work out why.

Stage Three: The Beginning Thinker

People in that stage have begun to apply critical thinking across their daily lives. They can see that many people use faulty logic and can even point-out in some cases what these faults actually are. They are also more self-aware than the 'challenged thinker'. They can understand that they can be wrong about things and are able to question the truth behind information being fed to them from different sources.

These individuals have started to put reason before emotion and sometimes won't believe in something just because they want to believe it to be true. Critical thinking is still a challenge though for the 'beginner thinker'.

Stage Four: The Practicing Thinker

This is now the level where reasoning skills begin to play a significant role in the day-to-day lives of the individual. They can evaluate not only the validity of an argument but can also understand the 'soundness' of the logical system being put into practice.

These people are also often being self-challenged. Instead of hoping for something to be true, they attempt to use logic and rationality as their guide.

Stage Five: The Advanced Thinker

The psychologists believe that this stage is found mostly as a result of higher college or university education. These individuals fully submit themselves to the law of reason and actively fight their own prejudices, putting rational thought above other considerations.

They also have intellectual empathy, which means that they are able to begin to understand why other people think the way they do but at the same time can easily identify flaws in the structure of the arguments made by those with whom they disagree. Importantly, they are able to identify why arguments are wrong, which is often far more difficult than identifying why arguments are correct.

Stage Six: The Master Thinker

This individual is very rare. These people have put logic above all else and are able to deal with every argument and problem critically. They consistently push themselves to reach new levels of critical thinking and are able to do that even in cases where it is deeply uncomfortable.

They have passed aside their ego in the search for validity and truth. They search for weaknesses and biases even in their own thinking and may question the very nature and axioms of knowledge and logic itself.

The question is though, how do we elevate ourselves and others to the next level? It is most certainly a difficult task precisely because we have to identify and put aside our own prejudices, hopes and fundamental beliefs. The authors of the study emphasise that :

"We must teach in such a way that students come to understand the power in knowing that whenever humans reason, they have no choice but to use certain predictable structures of thought: that thinking is inevitably driven by the questions, that we seek answers to questions for some purpose, that to answer questions, we need information, that to use information we must interpret it (i.e., by making inferences), and that our inferences, in turn, are based on assumptions, and have implications, all of which involves ideas or concepts within some point of view."

It is crucial then that we learn how to evaluate fundamental assumptions before reaching a conclusion if we want to have our will to be governed by logic rather than ignorance.

Critical Thinking

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 [1970]) 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 .

12. Controversies

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 [1970]) 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.
