How to think effectively: Six stages of critical thinking

when does critical thinking fully develop

Credit: Elder / Paul

  • Researchers propose six levels of critical thinkers: Unreflective thinkers, Challenged thinkers, Beginning thinkers, Practicing thinkers, Advanced thinkers, and Master thinkers.
  • The framework comes from educational psychologists Linda Elder and Richard Paul.
  • Teaching critical thinking skills is a crucial challenge in our times.

The coronavirus has not only decimated our populations, its spread has also attacked the very nature of truth and stoked inherent tensions between many different groups of people, both at local and international levels. Spawning widespread conspiracy theories and obfuscation by governments, the virus has also been a vivid demonstration of the need for teaching critical thinking skills necessary to survive in the 21st century. The stage theory of critical thinking development, devised by psychologists Linda Elder and Richard Paul , can help us gauge the sophistication of our current mental approaches and provides a roadmap to the thinking of others.

The researchers identified six predictable levels of critical thinkers, from ones lower in depth and effort to the advanced mind-masters, who are always steps ahead.

As the scientists write , moving up on this pyramid of thinking “is dependent upon a necessary level of commitment on the part of an individual to develop as a critical thinker.” Using your mind more effectively is not automatic and “is unlikely to take place “subconsciously.” In other words – you have to put in the work and keep doing it, or you’ll lose the faculty.

Here’s how the stages of intellectual development break down:

Unreflective thinker

These are people who don’t reflect about thinking and the effect it has on their lives. As such, they form opinions and make decisions based on prejudices and misconceptions while their thinking doesn’t improve.

Unreflective thinkers lack crucial skills that would allow them to parse their thought processes. They also do not apply standards like accuracy, relevance, precision, and logic in a consistent fashion.

How many such people are out there? You probably can guess based on social media comments. As Elder and Paul write , “it is perfectly possible for students to graduate from high school, or even college, and still be largely unreflective thinkers.”

Challenged thinker

This next level up thinker has awareness of the importance of thinking on their existence and knows that deficiencies in thinking can bring about major issues. As the psychologists explain, to solve a problem, you must first admit you have one.

People at this intellectual stage begin to understand that “high quality thinking requires deliberate reflective thinking about thinking”, and can acknowledge that their own mental processes might have many flaws. They might not be able to identify all the flaws, however.

A challenged thinker may have a sense that solid thinking involves navigating assumptions, inferences, and points of view, but only on an initial level. They may also be able to spot some instances of their own self-deception. The true difficulty for thinkers of this category is in not “believing that their thinking is better than it actually is, making it more difficult to recognize the problems inherent in poor thinking,” explain the researchers.

Thinkers at this level can go beyond the nascent intellectual humility and actively look to take control of their thinking across areas of their lives. They know that their own thinking can have blind spots and other problems and take steps to address those, but in a limited capacity.

Beginning thinker

Beginning thinkers place more value in reason, becoming self-aware in their thoughts. They may also be able to start looking at the concepts and biases underlying their ideas. Additionally, such thinkers develop higher internal standards of clarity, accuracy and logic, realizing that their ego plays a key role in their decisions.

Another big aspect that differentiates this stronger thinker – some ability to take criticism of their mental approach, even though they still have work to do and might lack clear enough solutions to the issues they spot.

Practicing thinker

This more experienced kind of thinker not only appreciates their own deficiencies, but has skills to deal with them. A thinker of this level will practice better thinking habits and will analyze their mental processes with regularity.

While they might be able to express their mind’s strengths and weaknesses, as a negative, practicing thinkers might still not have a systematic way of gaining insight into their thoughts and can fall prey to egocentric and self-deceptive reasoning.

How do you get to this stage? An important trait to gain, say the psychologists, is “intellectual perseverance.” This quality can provide “the impetus for developing a realistic plan for systematic practice (with a view to taking greater command of one’s thinking).”

“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,” explain Elder and Paul.

One doesn’t typically get to this stage until college and beyond, estimate the scientists. This higher-level thinker would have strong habits that would allow them to analyze their thinking with insight about different areas of life. They would be fair-minded and able to spot the prejudicial aspects in the points of view of others and their own understanding.

While they’d have a good handle on the role of their ego in the idea flow, such thinkers might still not be able to grasp all the influences that affect their mentality.

Advanced thinker

The advanced thinker is at ease with self-critique and does so systematically, looking to improve. Among key traits required for this level are “intellectual insight” to develop new thought habits, “ intellectual integrity” to “recognize areas of inconsistency and contradiction in one’s life,” intellectual empathy ” to put oneself in the place of others in order to genuinely understand them, and the “ intellectual courage” to confront ideas and beliefs they don’t necessarily believe in and have negative emotions towards.

Master thinker

This is the super-thinker, the one who is totally in control of how they process information and make decisions. Such people constantly seek to improve their thought skills, and through experience “regularly raise their thinking to the level of conscious realization.”

A master thinker achieves great insights into deep mental levels, strongly committed to being fair and gaining control over their own egocentrism.

Such a high-level thinker also exhibits superior practical knowledge and insight, always re-examining their assumptions for weaknesses, logic, and biases.

And, of course, a master thinker wouldn’t get upset with being intellectually confronted and spends a considerable amount of time analyzing their own responses.

“Why is this so important? Precisely because the human mind, left to its own, pursues that which is immediately easy, that which is comfortable, and that which serves its selfish interests. At the same time, it naturally resists that which is difficult to understand, that which involves complexity, that which requires entering the thinking and predicaments of others,” write the researchers.

So how do you become a master thinker? The psychologists think most students will never get there. But a lifetime of practicing the best intellectual traits can get you to that point when “people of good sense seek out master thinkers, for they recognize and value the ability of master thinkers to think through complex issues with judgment and insight.”

The significance of critical thinking in our daily lives, especially in these confusing times, so rife with quick and often-misleading information, cannot be overstated. The decisions we make today can truly be life and death.

What are critical thinking skills?

How to develop critical thinking skills: 12 tips, how to practice critical thinking skills at work, become your own best critic.

A client requests a tight deadline on an intense project. Your childcare provider calls in sick on a day full of meetings. Payment from a contract gig is a month behind. 

Your day-to-day will always have challenges, big and small. And no matter the size and urgency, they all ask you to use critical thinking to analyze the situation and arrive at the right solution. 

Critical thinking includes a wide set of soft skills that encourage continuous learning, resilience , and self-reflection. The more you add to your professional toolbelt, the more equipped you’ll be to tackle whatever challenge presents itself. Here’s how to develop critical thinking, with examples explaining how to use it.

Critical thinking skills are the skills you use to analyze information, imagine scenarios holistically, and create rational solutions. It’s a type of emotional intelligence that stimulates effective problem-solving and decision-making . 

When you fine-tune your critical thinking skills, you seek beyond face-value observations and knee-jerk reactions. Instead, you harvest deeper insights and string together ideas and concepts in logical, sometimes out-of-the-box , ways. 

Imagine a team working on a marketing strategy for a new set of services. That team might use critical thinking to balance goals and key performance indicators , like new customer acquisition costs, average monthly sales, and net profit margins. They understand the connections between overlapping factors to build a strategy that stays within budget and attracts new sales. 

Looking for ways to improve critical thinking skills? Start by brushing up on the following soft skills that fall under this umbrella: 

  • Analytical thinking: Approaching problems with an analytical eye includes breaking down complex issues into small chunks and examining their significance. An example could be organizing customer feedback to identify trends and improve your product offerings. 
  • Open-mindedness: Push past cognitive biases and be receptive to different points of view and constructive feedback . Managers and team members who keep an open mind position themselves to hear new ideas that foster innovation . 
  • Creative thinking: With creative thinking , you can develop several ideas to address a single problem, like brainstorming more efficient workflow best practices to boost productivity and employee morale . 
  • Self-reflection: Self-reflection lets you examine your thinking and assumptions to stimulate healthier collaboration and thought processes. Maybe a bad first impression created a negative anchoring bias with a new coworker. Reflecting on your own behavior stirs up empathy and improves the relationship. 
  • Evaluation: With evaluation skills, you tackle the pros and cons of a situation based on logic rather than emotion. When prioritizing tasks , you might be tempted to do the fun or easy ones first, but evaluating their urgency and importance can help you make better decisions. 

There’s no magic method to change your thinking processes. Improvement happens with small, intentional changes to your everyday habits until a more critical approach to thinking is automatic. 

Here are 12 tips for building stronger self-awareness and learning how to improve critical thinking: 

1. Be cautious

There’s nothing wrong with a little bit of skepticism. One of the core principles of critical thinking is asking questions and dissecting the available information. You might surprise yourself at what you find when you stop to think before taking action. 

Before making a decision, use evidence, logic, and deductive reasoning to support your own opinions or challenge ideas. It helps you and your team avoid falling prey to bad information or resistance to change .

2. Ask open-ended questions

“Yes” or “no” questions invite agreement rather than reflection. Instead, ask open-ended questions that force you to engage in analysis and rumination. Digging deeper can help you identify potential biases, uncover assumptions, and arrive at new hypotheses and possible solutions. 

3. Do your research

No matter your proficiency, you can always learn more. Turning to different points of view and information is a great way to develop a comprehensive understanding of a topic and make informed decisions. You’ll prioritize reliable information rather than fall into emotional or automatic decision-making.

4. Consider several opinions

You might spend so much time on your work that it’s easy to get stuck in your own perspective, especially if you work independently on a remote team . Make an effort to reach out to colleagues to hear different ideas and thought patterns. Their input might surprise you.

If or when you disagree, remember that you and your team share a common goal. Divergent opinions are constructive, so shift the focus to finding solutions rather than defending disagreements. 

5. Learn to be quiet

Active listening is the intentional practice of concentrating on a conversation partner instead of your own thoughts. It’s about paying attention to detail and letting people know you value their opinions, which can open your mind to new perspectives and thought processes.

If you’re brainstorming with your team or having a 1:1 with a coworker , listen, ask clarifying questions, and work to understand other peoples’ viewpoints. Listening to your team will help you find fallacies in arguments to improve possible solutions.

6. Schedule reflection

Whether waking up at 5 am or using a procrastination hack, scheduling time to think puts you in a growth mindset . Your mind has natural cognitive biases to help you simplify decision-making, but squashing them is key to thinking critically and finding new solutions besides the ones you might gravitate toward. Creating time and calm space in your day gives you the chance to step back and visualize the biases that impact your decision-making. 

7. Cultivate curiosity

With so many demands and job responsibilities, it’s easy to seek solace in routine. But getting out of your comfort zone helps spark critical thinking and find more solutions than you usually might.

If curiosity doesn’t come naturally to you, cultivate a thirst for knowledge by reskilling and upskilling . Not only will you add a new skill to your resume , but expanding the limits of your professional knowledge might motivate you to ask more questions. 

You don’t have to develop critical thinking skills exclusively in the office. Whether on your break or finding a hobby to do after work, playing strategic games or filling out crosswords can prime your brain for problem-solving. 

woman-solving-puzzle-at-home-how-to-develop-critical-thinking-skills

9. Write it down

Recording your thoughts with pen and paper can lead to stronger brain activity than typing them out on a keyboard. If you’re stuck and want to think more critically about a problem, writing your ideas can help you process information more deeply.

The act of recording ideas on paper can also improve your memory . Ideas are more likely to linger in the background of your mind, leading to deeper thinking that informs your decision-making process. 

10. Speak up

Take opportunities to share your opinion, even if it intimidates you. Whether at a networking event with new people or a meeting with close colleagues, try to engage with people who challenge or help you develop your ideas. Having conversations that force you to support your position encourages you to refine your argument and think critically. 

11. Stay humble

Ideas and concepts aren’t the same as real-life actions. There may be such a thing as negative outcomes, but there’s no such thing as a bad idea. At the brainstorming stage , don’t be afraid to make mistakes.

Sometimes the best solutions come from off-the-wall, unorthodox decisions. Sit in your creativity , let ideas flow, and don’t be afraid to share them with your colleagues. Putting yourself in a creative mindset helps you see situations from new perspectives and arrive at innovative conclusions. 

12. Embrace discomfort

Get comfortable feeling uncomfortable . It isn’t easy when others challenge your ideas, but sometimes, it’s the only way to see new perspectives and think critically.

By willingly stepping into unfamiliar territory, you foster the resilience and flexibility you need to become a better thinker. You’ll learn how to pick yourself up from failure and approach problems from fresh angles.

Thinking critically is easier said than done. To help you understand its impact (and how to use it), here are two scenarios that require critical thinking skills and provide teachable moments. 

Scenario #1: Unexpected delays and budget

Imagine your team is working on producing an event. Unexpectedly, a vendor explains they’ll be a week behind on delivering materials. Then another vendor sends a quote that’s more than you can afford. Unless you develop a creative solution, the team will have to push back deadlines and go over budget, potentially costing the client’s trust. 

Here’s how you could approach the situation with creative thinking:

  • Analyze the situation holistically: Determine how the delayed materials and over-budget quote will impact the rest of your timeline and financial resources . That way, you can identify whether you need to build an entirely new plan with new vendors, or if it’s worth it to readjust time and resources. 
  • Identify your alternative options: With careful assessment, your team decides that another vendor can’t provide the same materials in a quicker time frame. You’ll need to rearrange assignment schedules to complete everything on time. 
  • Collaborate and adapt: Your team has an emergency meeting to rearrange your project schedule. You write down each deliverable and determine which ones you can and can’t complete by the deadline. To compensate for lost time, you rearrange your task schedule to complete everything that doesn’t need the delayed materials first, then advance as far as you can on the tasks that do. 
  • Check different resources: In the meantime, you scour through your contact sheet to find alternative vendors that fit your budget. Accounting helps by providing old invoices to determine which vendors have quoted less for previous jobs. After pulling all your sources, you find a vendor that fits your budget. 
  • Maintain open communication: You create a special Slack channel to keep everyone up to date on changes, challenges, and additional delays. Keeping an open line encourages transparency on the team’s progress and boosts everyone’s confidence.

Scenario #2: Differing opinions 

A conflict arises between two team members on the best approach for a new strategy for a gaming app. One believes that small tweaks to the current content are necessary to maintain user engagement and stay within budget. The other believes a bold revamp is needed to encourage new followers and stronger sales revenue. 

Here’s how critical thinking could help this conflict:

  • Listen actively: Give both team members the opportunity to present their ideas free of interruption. Encourage the entire team to ask open-ended questions to more fully understand and develop each argument. 
  • Flex your analytical skills: After learning more about both ideas, everyone should objectively assess the benefits and drawbacks of each approach. Analyze each idea's risk, merits, and feasibility based on available data and the app’s goals and objectives. 
  • Identify common ground: The team discusses similarities between each approach and brainstorms ways to integrate both idea s, like making small but eye-catching modifications to existing content or using the same visual design in new media formats. 
  • Test new strategy: To test out the potential of a bolder strategy, the team decides to A/B test both approaches. You create a set of criteria to evenly distribute users by different demographics to analyze engagement, revenue, and customer turnover. 
  • Monitor and adapt: After implementing the A/B test, the team closely monitors the results of each strategy. You regroup and optimize the changes that provide stronger results after the testing. That way, all team members understand why you’re making the changes you decide to make.

You can’t think your problems away. But you can equip yourself with skills that help you move through your biggest challenges and find innovative solutions. Learning how to develop critical thinking is the start of honing an adaptable growth mindset. 

Now that you have resources to increase critical thinking skills in your professional development, you can identify whether you embrace change or routine, are open or resistant to feedback, or turn to research or emotion will build self-awareness. From there, tweak and incorporate techniques to be a critical thinker when life presents you with a problem.

How critical thinking skills develop: a brainy overview.

  • The Juice Team
  • December 17, 2020

Our greatest hope as parents and educators is that our children grow up to become high functioning members of society who can think intelligently, make educated decisions, and succeed in their chosen professions. The skill sets our children will need to develop to succeed in the 21st century are, however, different than those needed in previous decades. This change in skills demanded from the labor market has been the result of an economy transformed by ever-expanding automation, artificial intelligence, big data, and globalization. To succeed in our new, information-based economy, students will need skills beyond those traditionally tested in the classroom.

Comparing skill sets across several sources, including Forbes , Indeed , the World Bank , and Pearson & Nesta , it is clear that employers value high-order cognitive skills. Employers are seeking employees who can solve problems creatively, collaborate with team members effectively, work independently, and think critically among other interpersonal and interpersonal skills.

In order for us to best prepare our students for the opportunities and challenges awaiting them, we need to understand how higher-order thinking skills are developed. The brain can teach us a lot.

A Brief Overview of a Child’s Neurological Development 

when does critical thinking fully develop

While the brain takes nearly 25 years to fully develop, its most rapid changes occur during adolescence making it a critical period for students to engage in stimulating activities that promote thinking.

The Prefrontal Cortex: Home to Higher-Order Thinking

Put your hand on your forehead (as if you have a headache) – the area behind your hand is where your prefrontal cortex is located. The prefrontal cortex regulates our thoughts, emotions, and actions through extensive connections to other neural structures, and is the main center for critical thinking. Without it, we would not be able to perform many executive functions like problem-solving, reasoning, self-motivation, planning, decision-making, self-control, and the list goes on.

Compared to all other animals, the human brain has the greatest volume of prefrontal cortex — which is why humans have the greatest potential to think critically!

The prefrontal cortex is the last neural structure to mature. During adolescence, the prefrontal cortex both grows in a process called myelination and shrinks in a process called pruning . 

The Growing Adolescent Brain

New neural networks form when we repeat activities and link ideas. In a process called myelination, fatty “myelin sheaths” insulate connecting neurons to increase the speed and efficiency of the flow of information from one neural region to another. While myelination begins early in life and continues into adulthood, the production of myelin sheaths escalates during adolescence. Because myelination facilitates faster long-range connections in the brain, adolescents gain an increased ability to think abstractly and bring ideas together from different locations in the brain.

The Shrinking Adolescent Brain

During childhood and adolescents the brain soaks up information like a sponge, but there is only so much storage space in the brain. As a result, “ synaptic pruning ” occurs. This process is often referred to as the “ use it or lose it ” philosophy — the neural pathways that are underutilized are pruned or removed from the brain.

Basically, the brain decides which neural links to keep depending on how often they are used. So, if you want to speak a foreign language, play a musical instrument, or become a great athlete, you should engage in those activities before and during adolescence. 

Neurons that Fire Together, Wire Together

During this period of rapid neural development, learning actually changes how the adolescent brain is structured and how it functions. As teachers, parents, and mentors it is our responsibility to provide students with the foundational information and learning opportunities necessary to stimulate their developing neural networks of executive functions.

Neurons that fire together, wire together. Basically the more often you stimulate a neural-circuit in your brain, the stronger that circuit becomes. This phenomena explains why it becomes easier to speak a foreign language with practice and why learning how to play a second musical instrument is easier than learning how to play an instrument for the first time — practice strengthens the involved neural circuits.  

Given that schooling occurs when the brain is undergoing its most rapid period of growth, caregivers and educators play a critical part in changing adolescents’ neural structures and shaping their brain function. Research shows that “a well-developed prefrontal cortex with strong Executive Functions can improve both academic and life outcomes.”

Students, even if they don’t know it or admit it, need help in order to  take full advantage of this transformational period in their development.

when does critical thinking fully develop

How Can we Help Students Take Full Advantage of This Period of Rapid Brain Development?

1. encourage students to try many activities.

Many parents with student-athletes ask, “should my child play many sports or specialize?” Research has shown that children who play multiple sports become better athletes compared to those that focus on just one.

The same is true for the brain! Adolescents who are enrolled in a range of extracurricular activities engage more with their caregivers, learn more about their personal interests, are more active in their communities, and are less likely to engage in criminal activities.

2. Engage Adolescents in Conversation and Encourage Them to be Curious

MIT cognitive scientists have found that conversations between child and parent actually change the brain’s structure. Conversations that focus on solving problems collaboratively and building connections with others trigger physical and emotional changes in the brain enabling us to form relationships and think with empathy. Trust is mediated by the prefrontal cortex , so creating a safe-space where trust is present, is a prerequisite for the activation of the brain’s ability to think strategically, empathetically, and compassionately.

Asking adolescents open-ended questions is a great way to get your teen to think creatively without fear of giving a wrong answer. You can learn more about the power of understanding different perspectives here. (link to other blog post)

3. Create Safe and Secure Environments (with Reasonable Boundaries)

Creating a safe environment is important for more than just creating conversations. While the prefrontal cortex is developing, the amygdala (the brain region in charge of emotion) takes over. This explains why adolescents interpret most conversations and situations through an emotional, fear-attuned mind rather than a trust-seeking, rational one. By creating safe environments we help calm down the fear center of the brain and enhance learning. Furthermore given that the emotional and rational centers of the brain are not yet fully connected, it is normal for teens to act impulsively, engage in risk-taking behaviors, and feel overly self-conscious.

Creating safe spaces, defining boundaries, and creating opportunities for those boundaries to be negotiated, enables teens to take healthy risks and experiment with their sense of self, both of which contribute to healthy development. 

4. Promote Healthy Eating and Sleeping Habits 

The brain requires energy — sleep and healthy foods — to form new neural networks. Specifically, healthy fats like omega 3 fatty acids are used in the formation of myelin sheaths, which if you remember is what enables neural pathways to speed up connections between neurons and prevent connection interference. 

The brain only has so much room for new information — when we sleep the brain prunes (e.g. removes) unused networks and builds more streamlined efficient pathways. Thinking with a sleep-deprived brain is like trying to walk through a dense jungle. 

5. Provide Instructional and Motivational Feedback 

Given that the prefrontal cortex takes the longest time to mature, teens tend to process information with the amygdala, the brain’s center for processing emotion and fear. Because the connections between the prefrontal cortex, the brain’s rational part, and the amygdala are not yet fully formed a teen might misperceive a benign “hello” as “I’m watching you” or “I noticed that pimple.”  Additionally, until the prefrontal cortex is fully developed, teens might find it difficult to identify and balance short-term and long-term consequences of an action.

In a parenting guide published by Stanford Children’s Hospital , we learn that  “discussing the consequences of their actions can help teens link impulsive thinking with facts.” Our teens rely on us to point out these cognitive errors, and help guide them through complex decision-making. By setting good examples for our teens and providing feedback we can help rewire their brains in a healthy way.

Now you know how you can help teens maximize their brain potential! While adolescents are a crucial time to develop the brain, remember that everyone’s brain is plastic, including yours. No matter how old you are or what level your brain function is at today, your brain can improve. Stay engaged, stay curious, stay active, and read The Juice!

Critical Thinking and Decision-Making: What is Critical Thinking?

Lesson 1: what is critical thinking, what is critical thinking.

Critical thinking is a term that gets thrown around a lot. You've probably heard it used often throughout the years whether it was in school, at work, or in everyday conversation. But when you stop to think about it, what exactly is critical thinking and how do you do it ?

Watch the video below to learn more about critical thinking.

Simply put, critical thinking is the act of deliberately analyzing information so that you can make better judgements and decisions . It involves using things like logic, reasoning, and creativity, to draw conclusions and generally understand things better.

illustration of the terms logic, reasoning, and creativity

This may sound like a pretty broad definition, and that's because critical thinking is a broad skill that can be applied to so many different situations. You can use it to prepare for a job interview, manage your time better, make decisions about purchasing things, and so much more.

The process

illustration of "thoughts" inside a human brain, with several being connected and "analyzed"

As humans, we are constantly thinking . It's something we can't turn off. But not all of it is critical thinking. No one thinks critically 100% of the time... that would be pretty exhausting! Instead, it's an intentional process , something that we consciously use when we're presented with difficult problems or important decisions.

Improving your critical thinking

illustration of the questions "What do I currently know?" and "How do I know this?"

In order to become a better critical thinker, it's important to ask questions when you're presented with a problem or decision, before jumping to any conclusions. You can start with simple ones like What do I currently know? and How do I know this? These can help to give you a better idea of what you're working with and, in some cases, simplify more complex issues.  

Real-world applications

Let's take a look at how we can use critical thinking to evaluate online information . Say a friend of yours posts a news article on social media and you're drawn to its headline. If you were to use your everyday automatic thinking, you might accept it as fact and move on. But if you were thinking critically, you would first analyze the available information and ask some questions :

  • What's the source of this article?
  • Is the headline potentially misleading?
  • What are my friend's general beliefs?
  • Do their beliefs inform why they might have shared this?

After analyzing all of this information, you can draw a conclusion about whether or not you think the article is trustworthy.

Critical thinking has a wide range of real-world applications . It can help you to make better decisions, become more hireable, and generally better understand the world around you.

What Is Critical Thinking? | Definition & Examples

Published on May 30, 2022 by Eoghan Ryan . Revised on May 31, 2023.

Critical thinking is the ability to effectively analyze information and form a judgment .

To think critically, you must be aware of your own biases and assumptions when encountering information, and apply consistent standards when evaluating sources .

Critical thinking skills help you to:

  • Identify credible sources
  • Evaluate and respond to arguments
  • Assess alternative viewpoints
  • Test hypotheses against relevant criteria

Why is critical thinking important, critical thinking examples, how to think critically, other interesting articles, frequently asked questions about critical thinking.

Critical thinking is important for making judgments about sources of information and forming your own arguments. It emphasizes a rational, objective, and self-aware approach that can help you to identify credible sources and strengthen your conclusions.

Critical thinking is important in all disciplines and throughout all stages of the research process . The types of evidence used in the sciences and in the humanities may differ, but critical thinking skills are relevant to both.

In academic writing , critical thinking can help you to determine whether a source:

  • Is free from research bias
  • Provides evidence to support its research findings
  • Considers alternative viewpoints

Outside of academia, critical thinking goes hand in hand with information literacy to help you form opinions rationally and engage independently and critically with popular media.

Critical thinking can help you to identify reliable sources of information that you can cite in your research paper . It can also guide your own research methods and inform your own arguments.

Outside of academia, critical thinking can help you to be aware of both your own and others’ biases and assumptions.

Academic examples

However, when you compare the findings of the study with other current research, you determine that the results seem improbable. You analyze the paper again, consulting the sources it cites.

You notice that the research was funded by the pharmaceutical company that created the treatment. Because of this, you view its results skeptically and determine that more independent research is necessary to confirm or refute them. Example: Poor critical thinking in an academic context You’re researching a paper on the impact wireless technology has had on developing countries that previously did not have large-scale communications infrastructure. You read an article that seems to confirm your hypothesis: the impact is mainly positive. Rather than evaluating the research methodology, you accept the findings uncritically.

Nonacademic examples

However, you decide to compare this review article with consumer reviews on a different site. You find that these reviews are not as positive. Some customers have had problems installing the alarm, and some have noted that it activates for no apparent reason.

You revisit the original review article. You notice that the words “sponsored content” appear in small print under the article title. Based on this, you conclude that the review is advertising and is therefore not an unbiased source. Example: Poor critical thinking in a nonacademic context You support a candidate in an upcoming election. You visit an online news site affiliated with their political party and read an article that criticizes their opponent. The article claims that the opponent is inexperienced in politics. You accept this without evidence, because it fits your preconceptions about the opponent.

There is no single way to think critically. How you engage with information will depend on the type of source you’re using and the information you need.

However, you can engage with sources in a systematic and critical way by asking certain questions when you encounter information. Like the CRAAP test , these questions focus on the currency , relevance , authority , accuracy , and purpose of a source of information.

When encountering information, ask:

  • Who is the author? Are they an expert in their field?
  • What do they say? Is their argument clear? Can you summarize it?
  • When did they say this? Is the source current?
  • Where is the information published? Is it an academic article? Is it peer-reviewed ?
  • Why did the author publish it? What is their motivation?
  • How do they make their argument? Is it backed up by evidence? Does it rely on opinion, speculation, or appeals to emotion ? Do they address alternative arguments?

Critical thinking also involves being aware of your own biases, not only those of others. When you make an argument or draw your own conclusions, you can ask similar questions about your own writing:

  • Am I only considering evidence that supports my preconceptions?
  • Is my argument expressed clearly and backed up with credible sources?
  • Would I be convinced by this argument coming from someone else?

Critical thinking refers to the ability to evaluate information and to be aware of biases or assumptions, including your own.

Like information literacy , it involves evaluating arguments, identifying and solving problems in an objective and systematic way, and clearly communicating your ideas.

Critical thinking skills include the ability to:

You can assess information and arguments critically by asking certain questions about the source. You can use the CRAAP test , focusing on the currency , relevance , authority , accuracy , and purpose of a source of information.

Ask questions such as:

  • Who is the author? Are they an expert?
  • How do they make their argument? Is it backed up by evidence?

A credible source should pass the CRAAP test  and follow these guidelines:

  • The information should be up to date and current.
  • The author and publication should be a trusted authority on the subject you are researching.
  • The sources the author cited should be easy to find, clear, and unbiased.
  • For a web source, the URL and layout should signify that it is trustworthy.

Information literacy refers to a broad range of skills, including the ability to find, evaluate, and use sources of information effectively.

Being information literate means that you:

  • Know how to find credible sources
  • Use relevant sources to inform your research
  • Understand what constitutes plagiarism
  • Know how to cite your sources correctly

Confirmation bias is the tendency to search, interpret, and recall information in a way that aligns with our pre-existing values, opinions, or beliefs. It refers to the ability to recollect information best when it amplifies what we already believe. Relatedly, we tend to forget information that contradicts our opinions.

Although selective recall is a component of confirmation bias, it should not be confused with recall bias.

On the other hand, recall bias refers to the differences in the ability between study participants to recall past events when self-reporting is used. This difference in accuracy or completeness of recollection is not related to beliefs or opinions. Rather, recall bias relates to other factors, such as the length of the recall period, age, and the characteristics of the disease under investigation.

Understanding How the Brain Thinks

Neurologist and teacher Judy Willis describes how brains develop critical thinking skills.

Understanding How the Brain Works

For 21st century success, now more than ever, students will need a skill set far beyond the current mandated standards that are evaluated on standardized tests. The qualifications for success in today's ever-changing world will demand the ability to think critically, communicate clearly, use continually changing technology, be culturally aware and adaptive, and possess the judgment and open-mindedness to make complex decisions based on accurate analysis of information. The most rewarding jobs of this century will be those that cannot be done by computers.

For students to be best prepared for the opportunities and challenges awaiting them, they need to develop their highest thinking skills -- the brain's executive functions. These higher-order neural networks are undergoing their most rapid development during the school years, and teachers are in the best position to promote the activation of these circuits. With the help of their teachers, students can develop the skillsets needed to solve problems that have not yet been recognized, analyze information as it becomes rapidly available in the globalized communication systems, and to skillfully and creatively take advantage of the evolving technological advances as they become available.

Factory Model of Education Prepares for "Assembly Line" Jobs

Automation and computerization are exceeding human ability for doing repetitive tasks and calculations, but the educational model has not changed. The factory model of education, still in place today, was designed for producing assembly line workers to do assigned tasks correctly. These workers did not need to analyze, create, or question.

Ironically, in response to more information, many educators are mandated to teach more rote facts and procedures, and students are given bigger books with more to memorize. In every country where I've given presentations and workshops, the problem is the same: overstuffed curriculum.

Even in countries where high-stakes standardized testing is not a dominant factor, school curriculum and emphasis have changed to provide more time for this additional rote memorization. Creative opportunities -- the arts, debate, general P.E., collaborative work, and inquiry -- are sacrificed at the altar of more predigested facts to be passively memorized. These students have fewer opportunities to discover the connections between isolated facts and to build neural networks of concepts that are needed to transfer learning to applications beyond the contexts in which the information is learned and practiced.

The High Costs of Maintaining the Factory Model

If students do not have opportunities to develop their higher order, cognitive skillsets they won't develop the reason, logic, creative problem solving, concept development, media literacy, and communication skills best suited for the daily complexities of life or the professional jobs of their future. Without these skills, they won't be able to compete on the global employment market with students currently developing their executive functions.

Instead, the best jobs will go to applicants who analyze information as it becomes available, adapt when new information makes facts obsolete, and collaborate with other experts on a global playing field. All these skills require tolerance, willingness to consider alternative perspectives, and the ability to articulate one's ideas successfully.

As educators, it is our challenge to see that all students have opportunities to stimulate their developing executive function networks so when they leave school they have the critical skillsets to choose the career and life paths that will give them the most satisfaction.

Executive Function = Critical Thinking

What my field of neurology has called "executive functions" for over 100 years are these highest cognitive processes. These executive functions have been given a variety of less specific names in education terminology such as higher order thinking or critical thinking. These are skillsets beyond those computers can do because they allow for flexible, interpretive, creative, and multidimensional thinking -- suitable for current and future challenges and opportunities. Executive functions can be thought of as the skills that would make a corporate executive successful. These include planning, flexibility, tolerance, risk assessment, informed decision-making, reasoning, analysis, and delay of immediate gratification to achieve long-term goals. These executive functions further allow for organizing, sorting, connecting, prioritizing, self-monitoring, self-correcting, self-assessing, abstracting, and focusing.

The Prefrontal Cortex: Home to Critical Thinking

The executive function control centers develop in the prefrontal cortex (PFC). The PFC gives us the potential to consider and voluntarily control our thinking, emotional responses, and behavior. It is the reflective "higher brain" compared to the reactive "lower brain". This prime real estate of the PFC comprises the highest percentage of brain volume in humans, compared to all other animals, which is roughly 20% of our brains.

Animals, compared to humans, are more dependent on their reactive lower brains to survive in their unpredictable environments where it is appropriate that automatic responses not be delayed by complex analysis. As man developed more control of his environment, the luxury of a bigger reflective brain correlated with the evolution of the PFC to its current proportions.

The prefrontal cortex is the last part of the brain to mature. This maturation is a process of neuroplasticity that includes 1) the pruning of unused cells to better provide for the metabolic needs of more frequently used neurons and 2) strengthening the connections in the circuits that are most used. Another aspect of neuroplasticity is the growth of stronger and increased numbers of connections among neurons. Each of the brain's over one billion neurons holds only a tiny bit of information. It is only when multiple neurons connect through their branches (axons and dendrites) that a memory is stored and retrievable.

This prefrontal cortex maturation, the pruning and strengthening process, continues into the twenties, with the most rapid changes in the age range of 8-16. Electricity flows from neuron to neuron through the axons and dendrites. This electrical flow carries information and also provides the stimulus that promotes the growth of these connections. Each time a network is activated -- the information recalled for review or use -- the connections become stronger and faster (speed through a circuit is largely determined by the layers of myelin coating that are built up around the axons -- this is also in response to the flow of the electric current of information transport when the circuit is activated). The stimulation of these networks during the ages of their rapid development strongly influences the development of the executive functions -- the social-emotional control and the highest thinking skillsets that today's students will carry with them as they leave school and become adults.

Preparing Students for the Challenges and Opportunities of the 21st Century

We have the obligation to provide our students with opportunities to learn the required foundational information and procedures through experiences that stimulate their developing neural networks of executive functions. We activate these networks through active learning experiences that involve students' prefrontal cortex circuits of judgment, critical analysis, induction, deduction, relational thinking with prior knowledge activation, and prediction. These experiences promote creative information processing as students recognize relationships between what they learn and what they already know. This is when neuroplasticity steps in and new connections (dendrites, synapses, myelinated axons) physically grow between formerly separate memory circuits when they are activated together. This is the physical manifestation of the "neurons that fire together, wire together" phenomenon.

Unless new rote memories are incorporated into larger, relational networks, they remain isolated bits of data in small, unconnected circuits. It is through active mental manipulation with prior knowledge that new information becomes incorporated into the already established neural network of previously acquired related memory.

Teaching that Strengthens Executive Function Networks

Making the switch from memorization to mental manipulation is about applying, communicating, and supporting what one already knows. The incorporation of rote memorization into the sturdy existing networks of long-term memory takes place when students recognize relationships to the prior knowledge stored in those networks.

When you provide students with opportunities to apply learning, especially through authentic, personally meaningful activities with formative assessments and corrective feedback throughout a unit, facts move from rote memory to become consolidated into related memory bank, instead of being pruned away from disuse.

The disuse pruning is another aspect of the brain's neuroplasticity. To best support the frequently used networks, the brain essentially dissolves isolated small neural networks of "unincorporated" facts and procedures that are rarely activated beyond drills and tests.

In contrast, opportunities to process new learning through executive functions promote its linkage to existing related memory banks through the growth of linking dendrites and synapses.

Students need to be explicitly taught and given opportunities to practice using executive functions to organize, prioritize, compare, contrast, connect to prior knowledge, give new examples of a concept, participate in open-ended discussions, synthesize new learning into concise summaries, and symbolize new learning into new mental constructs, such as through the arts or writing across the curriculum.

How to Engage Students' Developing Neural Networks to Promote Executive Function

The recommendations here are a few of the ways to engage students' developing networks of executive functions while they are undergoing their most rapid phase of maturation during the school years. Part 2 of this blog will delve more deeply into the mental manipulation strategies that promote consolidation of new input into existing memory circuits.

Judgment: This executive function, when developed, promotes a student's ability to monitor the accuracy of his or her work. Guidance, experiences, and feedback in estimation; editing and revising one's own written work; and class discussions for conflict resolution can activate the circuitry to build judgment.

Prioritizing: This executive function helps students to separate low relevance details from the main ideas of a text, lecture, math word problem, or complete units of study. Prioritizing skills are also used when students are guided to see how new facts fit into broader concepts, to plan ahead for long-term projects/reports, and to keep records of their most successful strategies that make the most efficient use of their time.

Setting goals, providing self-feedback, monitoring progress: Until students fully develop this PFC executive function, they are limited in their capacity to set and stick to realistic and manageable goals. They need support in recognizing the incremental progress they make as they apply effort towards their larger goals (see my previous two blogs about the "video game" model: How to Plan Instruction Using the Video Game Model and A Neurologist Makes the Case for the Video Game Model as a Learning Tool ).

Model Metacognition Development Yourself

Planning learning opportunities to activate executive function often means going beyond the curriculum provided in textbooks. This is a hefty burden when you are also under the mandate of teaching a body of information that exceeds the time needed for successful mental manipulation.

When you do provide these executive function-activating opportunities, students will recognize their own changing attitudes and achievements. Students will begin to experience and comment on these insights, "I thought ... would be boring, but it was pretty interesting" and "This is the first time I really understood ... " or simply, "Thanks" and "That was cool."

These student responses are teachable moments to promote metacognition. Consider sharing the processes you use to create the instruction that they respond to positively. These discussions will help students recognize their abilities to extend their horizons and focus beyond simply getting by with satisfactory grades. They can build their executive functions of long-term goal-directed behavior, advance planning, delay of immediate gratification. In this way, they can take advantage of opportunities to review and revise work -- even when it has been completed -- rather than to be satisfied with "getting it done." Your input can help students see the link between taking responsibility for class participation, collaboration, and setting high self-standards for all classwork and homework, such that they can say, "I did my best and am proud of my efforts."

As written on the gate of my college, the message we can send our students is:

Climb high. Aim Far. Your goal the sun; Your aim the stars.

The concept of critical thinking has been defined in many complex ways, but for young students new to the concept, it can best be summed up as thinking and judging for yourself .

When you develop critical thinking skills, you will learn to evaluate information that you hear and process information that you collect while recognizing your implicit biases. You will analyze the evidence that is presented to you in order to make sure it is sound.

Recognize Common Fallacies

Fallacies are tricks of logic, and understanding them is the best way to avoid falling for them. There are many types of fallacies , and the more you think about them, the more readily you will recognize them all around you, especially in advertisements, arguments, and political discussions.

  • Bandwagon Appeals: Bandwagon appeals argue that you should follow along with something because everyone else believes it.
  • Scare Tactics: A scare tactic is the use of a scary story as an example to make you more likely to believe some underlying assumption.
  • Appeal to Emotion: An appeal to emotion uses a fiery speech or a tragic story to convince someone to side with you.
  • False Dichotomy: Often there are many sides to an argument, but a "false dichotomy" presents an issue as one side versus the other.

Characteristics of Critical Thinking

To become a critical thinker, you must develop a few skills.

  • Recognize assumptions you carry with you. Have you ever wondered why you believe the things that you believe? Do you believe things because you’ve been told to believe them? Step outside your own beliefs to observe from a neutral viewpoint. Be aware of assumptions and learn to self-reflect.
  • Process information honestly. People sometimes pass along information that is not really true (i.e. the "fake news" crisis).
  • Recognize a generalization. Girls don’t like bugs. Old people are wise. Cats make better pets. These are generalizations. They’re not always true, are they?
  • Evaluate old information and new ideas. There was a time when doctors thought leeches could cure us. Recognize that just because something is commonly accepted, doesn't mean it is true.
  • Produce new ideas based on sound evidence. Detectives solve crimes by collecting bits of truths and putting them all together like a puzzle. One small deceit can jeopardize an investigation. The entire truth-seeking process is destabilized by one piece of bad evidence, leading to a wrong conclusion.
  • Analyze a problem and recognize the complex parts. A mechanic must understand how an entire engine works before s/he can diagnose a problem. Sometimes it is necessary to deconstruct an engine to figure out which part isn’t working. You should approach big problems like this: break them down into smaller parts and observe carefully and deliberately.
  • Use precise vocabulary and communicate with clarity. The truth can be blurred by fuzzy language. It is important to develop your vocabulary so you can communicate truths accurately.
  • Manage emotions in response to a situation or problem. Don’t be fooled by stirred up, emotional plea or angry speech. Stay rational and keep your emotions in check as you encounter new information.
  • Judge your sources. Learn to recognize hidden agendas and bias when you collect information.

As students progress from high school into college and graduate school they must develop critical thinking skills in order to carry out research. Students will learn to identify good sources and bad sources , make logical conclusions, and develop new theories.

Our Conception of Critical Thinking...

getting started with critical thinking

"Critical thinking is the 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. In its exemplary form, it is based on universal intellectual values that transcend subject matter divisions: clarity, accuracy, precision, consistency, relevance, sound evidence, good reasons, depth, breadth, and fairness..."

"Critical thinking is self-guided, self-disciplined thinking which attempts to reason at the highest level of quality in a fairminded way. People who think critically attempt, with consistent and conscious effort, to live rationally, reasonably, and empathically. They are keenly aware of the inherently flawed nature of human thinking when left unchecked. They strive to diminish the power of their egocentric and sociocentric tendencies. They use the intellectual tools that critical thinking offers – concepts and principles that enable them to analyze, assess, and improve thinking. They work diligently to develop the intellectual virtues of intellectual integrity, intellectual humility, intellectual civility, intellectual empathy, intellectual sense of justice and confidence in reason. They realize that no matter how skilled they are as thinkers, they can always improve their reasoning abilities and they will at times fall prey to mistakes in reasoning, human irrationality, prejudices, biases, distortions, uncritically accepted social rules and taboos, self-interest, and vested interest.

They strive to improve the world in whatever ways they can and contribute to a more rational, civilized society. At the same time, they recognize the complexities often inherent in doing so. They strive never to think simplistically about complicated issues and always to consider the rights and needs of relevant others. They recognize the complexities in developing as thinkers, and commit themselves to life-long practice toward self-improvement. They embody the Socratic principle: The unexamined life is not worth living , because they realize that many unexamined lives together result in an uncritical, unjust, dangerous world."

Why Critical Thinking?

when does critical thinking fully develop

The Problem:

Everyone thinks; it is our nature to do so. But much of our thinking, left to itself, is biased, distorted, partial, uninformed, or down-right prejudiced. Yet the quality of our lives and that of what we produce, make, or build depends precisely on the quality of our thought. Shoddy thinking is costly, both in money and in quality of life. Excellence in thought, however, must be systematically cultivated.

A Brief Definition:

Critical thinking is the art of analyzing and evaluating thinking with a view to improving it. The Result: 

  A well-cultivated critical thinker:

  • raises vital questions and problems, formulating them clearly and precisely;
  • gathers and assesses relevant information, using abstract ideas to interpret it effectively;
  • comes to well-reasoned conclusions and solutions, testing them against relevant criteria and standards;
  • thinks openmindedly within alternative systems of thought, recognizing and assessing, as need be, their assumptions, implications, and practical consequences; and
  • communicates effectively with others in figuring out solutions to complex problems.

Critical thinking is, in short, self-directed, self-disciplined, self-monitored, and self-corrective thinking. It requires rigorous standards of excellence and mindful command of their use. It entails effective communication and problem-solving abilities, and a commitment to overcoming our native egocentrism and sociocentrism. Read more about our concept of critical thinking .

The Essential Dimensions of Critical Thinking

when does critical thinking fully develop

Our conception of critical thinking is based on the substantive approach developed by Dr. Richard Paul and his colleagues at the Center and Foundation for Critical Thinking over multiple decades. It is relevant to every subject, discipline, and profession, and to reasoning through the problems of everyday life. It entails five essential dimensions of critical thinking:

At the left is an overview of the first three dimensions. In sum, the elements or structures of thought enable us to "take our thinking apart" and analyze it. The intellectual standards are used to assess and evaluate the elements. The intellectual traits are dispositions of mind embodied by the fairminded critical thinker. To cultivate the mind, we need command of these essential dimensions, and we need to consistently apply them as we think through the many problems and issues in our lives.

Why the Analysis of Thinking Is Important If you want to think well, you must understand at least the rudiments of thought, the most basic structures out of which all thinking is made. You must learn how to take thinking apart. Analyzing the Logic of a Subject When we understand the elements of reasoning, we realize that all subjects, all disciplines, have a fundamental logic defined by the structures of thought embedded within them. Therefore, to lay bare a subject’s most fundamental logic, we should begin with these questions:

10 ways to develop y..., 10 ways to develop your critical thinking skills.

critical thinking skills concept showing anatomy of thought

Many a TV and movie hero would have you believe that all the best decisions are made with a ‘gut feeling’. Unlike that onscreen police detective whose hunches solve major crimes and get him the key to the city, however, most of us would likely be jobless if we operated this way.

While intuition can be a valuable skill in the workplace , most employers would prefer you excel in critical thinking and problem solving . So, what makes someone a critical thinker, exactly? It’s the ability to look at issues objectively and effectively, without letting bias or emotions cloud your judgement.

It’s not an easy task, but critical thinking improves your communication with others, helps you solve problems in the best interests of everyone involved, and allows you to see a clearer path to success and advancement in your career . The good news is you can begin right away, so read on to learn how to develop your critical thinking skills.

1. Take Time to Evaluate Your Decision Making

The first step in developing your critical thinking skills is to set aside time to evaluate your daily choices and decisions. In the same way a coach looks at a recording of a game to identify his team’s strengths and weaknesses, use this exercise to identify your successful actions that day, as well as the scenarios that didn’t turn out as well as you hoped.

Ask yourself a series of questions about those actions. What was your motivation? Did you achieve your goals? Did you do something contrary to your own belief system? Take the extra time to really think about your answers. You might want to keep a journal of these self-evaluations to help you spot patterns in your thinking and decision making .

2. Avoid Egocentrism

Most people evaluate issues or disagreements with the default view that they themselves are correct. Being a more critical thinker requires us to contemplate the possibility that we may be wrong or are acting in our own self-interest rather than the good of others or of the company we work for.

Two prominent authors and instructors in the field of critical thinking development , Richard Paul and Linda Elder, say that feelings of irritation and resentment during the workday can actually be signs of egocentric thinking. Considering how a ‘rational’ person (think Mr Spock from Star Trek ) might have reacted to the same situation can help you understand how your own emotions or bias affected your actions.

Those same emotions can also affect your interpretation of others’ actions. Taking arguments personally and feeling attacked by someone else’s opinion can cloud your judgement. Try to view their statements as an attempt to solve a problem or improve conditions, and not a strike against your self-worth.

3. Be an Active Listener

When someone is speaking to us, we are often more focused on what we’re going to say in response than in carefully listening to everything they’re sharing. We miss important details and don’t take the time to consider or fully comprehend their point of view.

Next time you converse with someone, actively listen to their story, their argument and even their criticisms. Cataloguing all this information without immediately reacting to it helps you improve your critical thinking skills and understand your colleagues better.

Active listening also gives you the time to experience and empathise with their situation, which is helpful for facilitating teamwork and resolving conflicts at work .

4. Analyse the Information

Gathering data is only the first step in the process of becoming a critical thinker. Achieving a goal or resolving an argument requires analysing all that information. This once again means asking a lot of questions.

  • What is the source of the information?
  • Are there gaps in logic in someone’s argument?
  • Are they using emotion rather than facts to sway your opinion?
  • Is there any evidence to support their point of view or yours?

In a work environment, you have to carefully dissect each side of an issue, and then consider how any decision would affect your colleagues as well as the company’s bottom line.

5. Gather Research

Another important step in improving your critical thinking skills is to accept that you don’t know everything. Many articles have been written about common misconceptions about a whole range of subjects, so you should always take the time to verify any ‘facts’ you base your decisions or arguments on.

The trick of researching is to find reliable information. Always check the source. Is it a well-respected journal or news outlet? Is the author an educated and experienced expert? Can you verify the same information from multiple sites or authorities?

Critical thinkers also consider an author’s agenda, anything from a political affiliation to a product to sell.

6. Develop Your Curiosity

Think about the last time you conversed with someone who asked you a lot of detailed questions and made you uncomfortable. We often spend time with friends, sharing opinions without challenge, and it can be startling when someone actually calls us out on those opinions. Forced to explain our thought process, we may realise our argument wasn’t that sound after all.

If you want to develop your critical thinking, it’s time to be that questioning person. When someone shares an idea or judgement, don’t just accept it and move on to the next thing. Indulge your curiosity and ask some open-ended questions to get more details, and further explore the issue.

7. Approach Arguments with Compassion

In the age of social media discourse, which can escalate rapidly from name-calling to harassment to even death threats, a peaceful approach can be daunting. The first step is to look for the logic in an opponent’s argument. Focus on the critical thinking skills you apply to your own decisions and examine their motivations, evidence and reasoning.

Making an immediate effort to understand the opposing point of view can help keep you from becoming defensive and escalating the disagreement. The compassionate approach won’t necessarily lead to complete harmony, but an open mind allows you to examine all the information and, hopefully, find common ground.

The ability to understand others’ emotions and skilfully negotiate with them is considered a valuable skill to potential employers . Becoming a critical thinker in highly charged situations needn't be wasted on Twitter flame wars; it’s extremely useful in making a sale to a difficult client, keeping an unhappy customer on board or even convincing your boss to use your idea for a new product line instead of theirs.

8. Examine Decisions in Multiple Environments

When facing a difficult decision, everyone has heard the advice to ‘sleep on it’. This is sound advice. One of the main pillars of critical thinking is to remove emotion from the equation. If you’ve just had an argument with a colleague, you’ve been reprimanded by your boss for a mistake or even if you’ve just had an all-around bad day at work , it’s best to hold off on important decisions until you feel calmer and more rational.

Even when things are peaceful, take the time to look at a problem from multiple angles. Change your environment, mood, and who you interact with to help spark creative thinking and get you to a solution you might not have considered at the start.

9. Assign Yourself a Problem to Work On

Any skill you want to master requires practice. Applying critical thinking in your daily interactions will help you improve, but a specific task is also useful. Think of an issue in your career and spend any free moments during the day, like during your commute or on your lunch break, breaking that problem down into pieces you can analyse.

The goal during this analysis is to identify actionable elements. What can you do right now? What moves can you make over time to reach the perfect solution? How can you work around the issues that you can’t control? Continue to analyse the results after you act and adapt your strategies as you move forward.

Critical thinking and problem solving have always been useful at work, but employers will increasingly look for these skills as jobs become more complex and challenging due to ever-evolving technology and globalisation. Continue to assign yourself problems to tackle; even minor issues will help you keep your critical skills sharp.

10. Talk to a More Diverse Group of People

You can develop critical thinking skills with a lot of self-reflection, research and study, but staying locked in your own bubble can lead right back to egocentrism. Seek out people with different backgrounds, experiences and opinions to simply learn from them or to engage in some lively debate.

One of the most positive aspects of the internet is that it allows us to make these connections more easily. Aside from forums, group chats and social media, consider guesting on a podcast in your field of expertise. The more casual format can lead to some lively discussions and will force you to apply all your critical thinking skills on the fly. You can approach podcasters directly or try out services like Podcast Guests to connect you with interested hosts.

The key to improving your critical thinking skills is to constantly ask questions and seek the truth about everyone’s motives and actions, including your own. You won’t always be able to keep emotions out of an argument but practising these critical thinking strategies will help you find your way through difficult and complex situations to the best possible outcome.

Can you think of a time when these strategies helped you solve a problem at work? Do you have your own techniques for perfecting critical thinking? Let us know in the comments section below.

Age and Critical Thinking

Observing mature students in educational settings..

Posted August 14, 2017 | Reviewed by Jessica Schrader

In my introductory post , I addressed an observation of mine from teaching undergraduate critical thinking (CT), which is that students, especially mature students (i.e., aged 23 years and over), think they’re pretty good at CT, even when they’re not … well, not as good as they think they are, anyway! This can be interpreted as meaning that mature students are often overconfident in their ability to think critically. However, there are limitations to this assertion. Although there is a certain bravado associated with mature students and the way that they might engage with the class and speak about their opinions and experiences, this confidence is not necessarily seen when CT disposition is measured. That is, though mature students score slightly higher on CT disposition, there is no significant difference between them and younger, third-level students (i.e., 18- to 22-year-olds). Both score roughly at the mid-range between the lowest and highest possible scores (Dwyer & Walsh, in preparation).

When it comes down to evaluating their motivation and inclinations to think critically, it is possible that mature students are more realistic and honest than other students on self-report measures, despite what is observed in their behaviour. It’s possible that scores are "subdued" as a result of some form of social desirability; that is, perhaps mature students don’t want to appear overconfident in how they approach CT, when pen comes to paper. Conversely, it is also possible that it is younger students who are overconfident, on paper anyway, relative to their behaviour in the classroom. However, these interpretations are just possibilities at best, given that disposition towards thinking (i.e., the extent to which an individual is disposed, inclined, or willing, to perform a given thinking skill [Dwyer et al., 2017; Siegel 1999; Valenzuela et al., 2011]) is generally scored via self-report measures, which have in the past been criticized for a variety of reasons, particularly in assessing components of CT (see Ku, 2009). Also worth noting is that confidence and disposition are not exactly the same thing. Disposition towards thinking is a marker of how much we are inclined or how much we value certain aspects of cognition . It can be argued that the self-report nature of this inclination is itself the test of confidence (i.e., how confident one is that they actually conduct themselves or value something in the way they say they do). However, disposition doesn’t guarantee follow-through. Thus, a better indicator of assessing potential overconfidence in CT is looking at disposition relative to the performance of CT skills.

In a case study that I’m currently preparing with a colleague for publication, the effects of an adult distance learning CT module on CT performance were examined. In the context of the case study, adult distance learning refers to a mode of education in which students are employed adults (N=96) who have returned to part-time, formal education and are completing a Training and Education BA degree through an integration of traditional classroom instruction and e-learning. Performances were compared with a similar cohort of younger students who were also completing a BA and a blended learning CT module (N=42). It was hypothesised that due to the mature students’ age (which increases the likelihood of more metacognitive engagement); and potentially enhanced autonomy (Keegan, 1996; Knowles et al. 2005), student responsibility (Wedemeyer, 1981) and locus of control (Rotter, 1989), that their peformances would be significantly better than those of younger students. As hypothesised, mature students (M = 42.04 years) performed significantly better over time, in terms of CT ability (p = .004, ηp² = .07), than younger students (M = 18.96 years). However, younger students significantly outperformed the mature students prior to any CT training at baseline assessment (p < .001, d = .77).

Though these results are derived from a small-scale case study, the findings will be interesting to consider in future research for a number of reasons. First, as hypothesised, they imply that it is possible for more mature students to gain more from CT instruction than younger students. Second, they imply that, without appropriate CT instruction, younger students are better critical thinkers. Though this result contradicted the intial hypothesis, it is consistent with the perspective that though particular individuals may have more experience (and perhaps more confidence as well) in certain contexts, their higher-order thinking may not correlate due to experience in doing the ‘wrong thing’ or making poor decisions (Kahneman, 2011). A similar perspective is that perhaps maturer individuals may be more ‘set in their ways’ and it may be more difficult for them to adapt their beliefs in light of new information that may falsify their existing knowledge or belief systems (Kahneman, 2011). Third, and perhaps more central to the point of overconfidence, is that though mature students report approximately the same level of disposition towards thinking as younger college students, their ability to apply CT skills, before the intervention of CT training, does not match younger students’ ability.

To some extent, it is fair to say that though mature students think they’re pretty good at CT, often they are not. But, perhaps a more accurate interpretation is that without adequate training in CT, mature students’ perceptions of how they approach CT does not match their actual ability. This is consistent with a large body of research dating back to the 1960s that indicates that we often overestimate our abilities and fall prey to self-serving biases. But, this is the case for a lot of people — why single out more mature students? Simply, as individuals get older, they accrue more experience. There is also a tendency to equate this experience with varying conceptualizations of wisdom . However, experience is very often observed to be unrelated to the decision accuracy of expert judgments and sometimes negatively correlated with decision accuracy (Goldberg, 1990; Hammond, 1996; Kahneman, 2011; Stewart et al., 1992), perhaps as a result of overconfidence (Kahneman, 2011) or, to reiterate, experience in doing the wrong thing (Hammond, 1996). Thus, experience can be misleading.

In conclusion, without adequate training in CT, our perception of how we approach CT does not always match our actual CT ability. What makes this particularly interesting, in more mature populations, is that despite potentially enhanced autonomy, student responsibility and locus of control, it may be that an over- optimistic outlook on the benefits of experience (and its associated heuristic -based, intuitive judgment) takes centre-stage above and beyond actual ability. However, with appropriate training in CT, we see ability significantly improve over time. Thus, if you really care about your decisions and wish to improve how you solve problems and draw conclusions, it is never too late for critical thinking training.

How to build your critical thinking skills in 7 steps (with examples)

Julia Martins contributor headshot

Critical thinking is, well, critical. By developing critical thinking skills, you improve your ability to analyze information and come to the best decision possible. In this article, we cover the basics of critical thinking, as well as the seven steps you can use to implement the full critical thinking process.

Critical thinking comes from asking the right questions to come to the best conclusion possible. Strong critical thinkers analyze information from a variety of viewpoints in order to identify the best course of action.

Don’t worry if you don’t think you have strong critical thinking skills. In this article, we’ll help you build a foundation for critical thinking so you can absorb, analyze, and make informed decisions. 

What is critical thinking? 

Critical thinking is the ability to collect and analyze information to come to a conclusion. Being able to think critically is important in virtually every industry and applicable across a wide range of positions. That’s because critical thinking isn’t subject-specific—rather, it’s your ability to parse through information, data, statistics, and other details in order to identify a satisfactory solution. 

Definitions of critical thinking

Various scholars have provided definitions of critical thinking, each emphasizing different aspects of this complex cognitive process:

Michael Scriven , an American philosopher, defines critical thinking as "the 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."

Robert Ennis , professor emeritus at the University of Illinois, describes critical thinking as "reasonable, reflective thinking focused on deciding what to believe or do."

Diane Halpern , a cognitive psychologist and former president of the American Psychological Association, defines it as "the use of cognitive skills or strategies that increase the probability of a desirable outcome."

8 essential critical thinking skills to develop

Critical thinking is essential for success in everyday life, higher education, and professional settings. The handbook "Foundation for Critical Thinking" defines it as a process of conceptualization, analysis, synthesis, and evaluation of information.

In no particular order, here are eight key critical thinking abilities that can help you excel in any situation:

1. Analytical thinking

Analytical thinking involves evaluating data from multiple sources in order to come to the best conclusions. Analytical thinking allows people to reject cognitive biases and strive to gather and analyze intricate subject matter while solving complex problems. Analytical thinkers who thrive at critical thinking can:

Identify patterns and trends in the data

Break down complex issues into manageable components

Recognize cause-and-effect relationships

Evaluate the strength of arguments and evidence

Example: A data analyst breaks down complex sales figures to identify trends and patterns that inform the company's marketing strategy.

2. Open-mindedness

Open-mindedness is the willingness to consider new ideas, arguments, and information without prejudice. This critical thinking skill helps you analyze and process information to come to an unbiased conclusion. Part of the critical thinking process is letting your personal biases go, taking information at face value and coming to a conclusion based on multiple points of view .

Open-minded critical thinkers demonstrate:

Willingness to consider alternative viewpoints

Ability to suspend judgment until sufficient evidence is gathered

Receptiveness to constructive criticism and feedback

Flexibility in updating beliefs based on new information

Example: During a product development meeting, a team leader actively considers unconventional ideas from junior members, leading to an innovative solution.

3. Problem-solving

Effective problem solving is a cornerstone of critical thinking. It requires the ability to identify issues, generate possible solutions, evaluate alternatives, and implement the best course of action. This critical thinking skill is particularly valuable in fields like project management and entrepreneurship.

Key aspects of problem-solving include:

Clearly defining the problem

Gathering relevant information

Brainstorming potential solutions

Evaluating the pros and cons of each option

Implementing and monitoring the chosen solution

Reflecting on the outcome and adjusting as necessary

Example: A high school principal uses problem-solving skills to address declining student engagement by surveying learners, consulting with higher education experts, and implementing a new curriculum that balances academic rigor with practical, real-world applications.

4. Reasoned judgment

Reasoned judgment is a key component of higher order thinking that involves making thoughtful decisions based on logical analysis of evidence and thorough consideration of alternatives. This critical thinking skill is important in both academic and professional settings. Key aspects reasoned judgment include:

Objectively gathering and analyzing information

Evaluating the credibility and relevance of evidence

Considering multiple perspectives before drawing conclusions

Making decisions based on logical inference and sound reasoning

Example: A high school science teacher uses reasoned judgment to design an experiment, carefully observing and analyzing results before drawing conclusions about the hypothesis.

5. Reflective thinking

Reflective thinking is the process of analyzing one's own thought processes, actions, and outcomes to gain deeper understanding and improve future performance. Good critical thinking requires analyzing and synthesizing information to form a coherent understanding of a problem. It's an essential critical thinking skill for continuous learning and improvement.

Key aspects of reflective thinking include:

Critically examining one's own assumptions and cognitive biases

Considering diverse viewpoints and perspectives

Synthesizing information from various experiences and sources

Applying insights to improve future decision-making and actions

Continuously evaluating and adjusting one's thinking processes

Example: A community organizer reflects on the outcomes of a recent public event, considering what worked well and what could be improved for future initiatives.

6. Communication

Strong communication skills help critical thinkers articulate ideas clearly and persuasively. Communication in the workplace is crucial for effective teamwork, leadership, and knowledge dissemination. Key aspects of communication in critical thinking include:

Clearly expressing complex ideas

Active listening and comprehension

Adapting communication styles to different audiences

Constructing and delivering persuasive arguments

Example: A manager effectively explains a new company policy to her team, addressing their concerns and ensuring everyone understands its implications.

7. Research

Critical thinkers with strong research skills gather, evaluate, and synthesize information from various sources of information. This is particularly important in academic settings and in professional fields that require continuous learning. Effective research involves:

Identifying reliable and relevant sources of information

Evaluating the credibility and bias of sources

Synthesizing information from multiple sources

Recognizing gaps in existing knowledge

Example: A journalist verifies information from multiple credible sources before publishing an article on a controversial topic.

8. Decision-making

Effective decision making is the culmination of various critical thinking skills that allow an individual to draw logical conclusions and generalizations. It involves weighing options, considering consequences, and choosing the best course of action. Key aspects of decision-making include:

Defining clear criteria for evaluation

Gathering and analyzing relevant information

Considering short-term and long-term consequences

Managing uncertainty and risk

Balancing logic and intuition

Example: A homeowner weighs the costs, benefits, and long-term implications before deciding to invest in solar panels for their house.

How to develop critical thinking skills in 7 steps

Critical thinking is a skill that you can build by following these seven steps. The seven steps to critical thinking help you ensure you’re approaching a problem from the right angle, considering every alternative, and coming to an unbiased conclusion.

First things first: When to use the 7 step critical thinking process

There’s a lot that goes into the full critical thinking process, and not every decision needs to be this thought out. Sometimes, it’s enough to put aside bias and approach a process logically. In other, more complex cases, the best way to identify the ideal outcome is to go through the entire critical thinking process. 

The seven-step critical thinking process is useful for complex decisions in areas you are less familiar with. Alternatively, the seven critical thinking steps can help you look at a problem you’re familiar with from a different angle, without any bias. 

If you need to make a less complex decision, consider another problem solving strategy instead. Decision matrices are a great way to identify the best option between different choices. Check out our article on 7 steps to creating a decision matrix .

1. Identify the problem or question

Before you put those critical thinking skills to work, you first need to identify the problem you’re solving. This step includes taking a look at the problem from a few different perspectives and asking questions like: 

What’s happening? 

Why is this happening? 

What assumptions am I making? 

At first glance, how do I think we can solve this problem? 

A big part of developing your critical thinking skills is learning how to come to unbiased conclusions. In order to do that, you first need to acknowledge the biases that you currently have. Does someone on your team think they know the answer? Are you making assumptions that aren’t necessarily true? Identifying these details helps you later on in the process. 

2. Gather relevant information

At this point, you likely have a general idea of the problem—but in order to come up with the best solution, you need to dig deeper. 

During the research process, collect information relating to the problem, including data, statistics, historical project information, team input, and more. Make sure you gather information from a variety of sources, especially if those sources go against your personal ideas about what the problem is or how to solve it.

Gathering varied information is essential for your ability to apply the critical thinking process. If you don’t get enough information, your ability to make a final decision will be skewed. Remember that critical thinking is about helping you identify the objective best conclusion. You aren’t going with your gut—you’re doing research to find the best option

3. Analyze and evaluate data

Just as it’s important to gather a variety of information, it is also important to determine how relevant the different information sources are. After all, just because there is data doesn’t mean it’s relevant. 

Once you’ve gathered all of the information, sift through the noise and identify what information is relevant and what information isn’t. Synthesizing all of this information and establishing significance helps you weigh different data sources and come to the best conclusion later on in the critical thinking process. 

To determine data relevance, ask yourself:

How reliable is this information? 

How significant is this information? 

Is this information outdated? Is it specialized in a specific field? 

4. Consider alternative points of view

One of the most useful parts of the critical thinking process is coming to a decision without bias. In order to do so, you need to take a step back from the process and challenge the assumptions you’re making. 

We all have bias—and that isn’t necessarily a bad thing. Unconscious biases (also known as cognitive biases) often serve as mental shortcuts to simplify problem solving and aid decision making. But even when biases aren’t inherently bad, you must be aware of your biases in order to put them aside when necessary. 

Before coming to a solution, ask yourself:

Am I making any assumptions about this information? 

Are there additional variables I haven’t considered? 

Have I evaluated the information from every perspective? 

Are there any viewpoints I missed?

5. Draw logical conclusions

Finally, you’re ready to come to a conclusion. To identify the best solution, draw connections between causes and effects. Use the facts you’ve gathered to evaluate the most objective conclusion. 

Keep in mind that there may be more than one solution. Often, the problems you’re facing are complex and intricate. The critical thinking process doesn’t necessarily lead to a cut-and-dry solution—instead, the process helps you understand the different variables at play so you can make an informed decision. 

6. Develop and communication solutions

Communication is a key skill for critical thinkers. It isn’t enough to think for yourself—you also need to share your conclusion with other project stakeholders. If there are multiple solutions, present them all. There may be a case where you implement one solution, then test to see if it works before implementing another solution. 

This process of communicating and sharing ideas is key in promoting critical thinking abilities within a team or organization. By encouraging open dialogue and collaborative problem-solving, you create an environment that fosters the development of critical thinking skills in others.

7. Reflect and learn from the process

The seven-step critical thinking process yields a result—and you then need to put that solution into place. After you’ve implemented your decision, evaluate whether or not it was effective. Did it solve the initial problem? What lessons—whether positive or negative—can you learn from this experience to improve your critical thinking for next time? 

By engaging in this metacognitive reflective thinking process, you're essentially teaching critical thinking skills to yourself, refining your methodology with each iteration. This reflective practice is fundamental in developing a more robust and adaptable approach to problem-solving.

Depending on how your team shares information, consider documenting lessons learned in a central source of truth. That way, team members that are making similar or related decisions in the future can understand why you made the decision you made and what the outcome was.

Critical thinking examples in the workplace

Imagine you work in user experience design (UX). Your team is focused on pricing and packaging and ensuring customers have a clear understanding of the different services your company offers. Here’s how to apply the critical thinking process in the workplace in seven steps: 

Step 1: Start by identifying the problem

Your current pricing page isn’t performing as well as you want. You’ve heard from customers that your services aren’t clear, and that the page doesn’t answer the questions they have. This page is really important for your company, since it’s where your customers sign up for your service. You and your team have a few theories about why your current page isn’t performing well, but you decide to apply the critical thinking process to ensure you come to the best decision for the page. 

Gather information about how the problem started

Part of identifying the problem includes understanding how the problem started. The pricing and packaging page is important—so when your team initially designed the page, they certainly put a lot of thought into it. Before you begin researching how to improve the page, ask yourself: 

Why did you design the pricing page the way you did? 

Which stakeholders need to be involved in the decision making process? 

Where are users getting stuck on the page?

Are any features currently working?

Step 2: Then gather information and research

In addition to understanding the history of the pricing and packaging page, it’s important to understand what works well. Part of this research means taking a look at what your competitor’s pricing pages look like. 

Ask yourself: 

How have our competitors set up their pricing pages?

Are there any pricing page best practices? 

How does color, positioning, and animation impact navigation? 

Are there any standard page layouts customers expect to see? 

Step 3: Organize and analyze information

You’ve gathered all of the information you need—now you need to organize and analyze it. What trends, if any, are you noticing? Is there any particularly relevant or important information that you have to consider? 

Step 4: Consider alternative viewpoints to reduce bias

In the case of critical thinking, it’s important to address and set bias aside as much as possible. Ask yourself: 

Is there anything I’m missing? 

Have I connected with the right stakeholders? 

Are there any other viewpoints I should consider? 

Step 5: Determine the most logical solution for your team

You now have all of the information you need to design the best pricing page. Depending on the complexity of the design, you may want to design a few options to present to a small group of customers or A/B test on the live website.

Step 6: Communicate your solution to stakeholders

Critical thinking skills can help you in every element of your life, but in the workplace, you must also involve key project stakeholders . Stakeholders help you determine next steps, like whether you’ll A/B test the page first. Depending on the complexity of the issue, consider hosting a meeting or sharing a status report to get everyone on the same page. 

Step 7: Reflect on the results

No process is complete without evaluating the results. Once the new page has been live for some time, evaluate whether it did better than the previous page. What worked? What didn’t? This also helps you make better critical decisions later on.

Tools and techniques to improve critical thinking skills

Understanding how to improve critical thinking skills has become a cornerstone of personal and professional growth in the 21st century. Recognizing the importance of critical thinking, experts across various disciplines have contributed valuable insights and methodologies. Here are some notable contributions from experts and institutions in the field:

Mind mapping: A visual approach to critical thinking skills

Mind mapping is a visual technique that helps organize and structure information. It's particularly useful for synthesizing complex ideas and identifying connections between different concepts. The benefits of mind mapping include:

Enhancing creativity by encouraging non-linear thinking

Improving memory and retention of information

Facilitating brainstorming and idea generation

Providing a clear overview of complex topics

To create a mind map:

Start with a central idea or concept.

Branch out with related sub topics or ideas.

Use colors, symbols, and images to enhance visual appeal and memorability.

Draw connections between related ideas across different branches.

Mind mapping can be particularly effective in project planning , content creation, and studying complex subjects.

The Socratic Method: Deepening critical thinking skills

The Socratic Method, named after the ancient Greek philosopher Socrates, involves asking probing questions to stimulate critical thinking and illuminate ideas. This technique is widely used in higher education to teach critical thinking. Key aspects of the Socratic Method include:

Asking open-ended questions that encourage deeper reflection

Challenging assumptions and preconceived notions

Exploring the implications and consequences of ideas

Fostering intellectual curiosity and continuous inquiry

The Socratic Method can be applied in various settings:

In education, to encourage students to think deeply about subject matter

In business, it is important to challenge team members to consider multiple points of view.

In personal development, to examine one's own beliefs and decisions

Example: A high school teacher might use the Socratic Method to guide students through a complex ethical dilemma, asking questions like "What principles are at stake here?" and "How might this decision affect different stakeholders?"

SWOT analysis: Comprehensive critical thinking skills

SWOT (Strengths, Weaknesses, Opportunities, Threats) analysis is a strategic planning tool that can be applied to critical thinking. It helps in evaluating situations from multiple angles, promoting a more thorough understanding of complex issues. The components of SWOT analysis are:

Strengths: internal positive attributes or assets

Weaknesses: internal negative attributes or limitations

Opportunities: External factors that could be beneficial

Threats: External factors that could be harmful

To conduct a SWOT analysis:

Clearly define the subject of analysis (e.g., a project, organization, or decision).

Brainstorm and list items for each category.

Analyze the interactions between different factors.

Use the analysis to inform strategy or decision-making.

Example: A startup might use SWOT analysis to evaluate its position before seeking investment, identifying its innovative technology as a strength, limited capital as a weakness, growing market demand as an opportunity, and established competitors as a threat.

Critical thinking resources

Parents' Guide

Introduction, critical thinking development: ages 5 to 9.

Critical thinking must be built from a solid foundation. Although children aged five to nine are not yet ready to take on complicated reasoning or formulate detailed arguments, parents can still help their children lay a foundation for critical thinking. 

In order to develop high-level critical thinking skills later in life, five- to nine-year-old children must first make progress along four different tracks. This includes developing basic reasoning skills and interests, building self-esteem, learning emotional management skills, and internalizing social norms that value critical thinking. The following sections will discuss the importance of these foundational aspects of critical thinking and offer parents guidance in how to support their young children’s development.

1. Logic and Critical Thinking

Formal logic is an important part of critical thinking, but ultimately critical thinking involves habits and skills going far beyond the domain of logic. Children are able to develop their critical faculties not from logical analysis, but everyday reasoning.

There are three main factors to keep in mind in differentiating logic from the everyday reasoning that underpins critical thinking.

First, logic is not a natural human trait. If logic were natural, we wouldn’t have to learn how to reason, and math wouldn’t be considered so difficult in school. The natural reasoning displayed by children is often founded on sensory experiences and marred by the cognitive biases discussed in the introduction. Consider this example. Someone says: “If it rains, I’ll take my umbrella with me.” And then a moment later adds: “It’s not raining.” What may we conclude? The vast majority of people — including both adults and children old enough to understand the question — will conclude that the person will not take an umbrella. In context, that is a reasonable conclusion to draw. 

Critical thinking is different from logical thinking. Logical thinking is like math: it involves formal reasoning skills that can only be learned later in life. In contrast, critical thinking builds on everyday reasoning. So parents should guide their children’s critical thinking development from a very young age.

Logic is not natural to humans and can only be acquired through learning.

when does critical thinking fully develop

But from a purely logical perspective, it does not follow. The fact that if it does rain, the speaker will take an umbrella implies nothing, strictly speaking, about what will happen in the case that it is not raining. Logic, the cognitive capacity for formal and reliable deduction, is not natural to humans. We can only acquire it through learning—and only at an age when the cognitive system and brain development allow for such learning (between ages 12 and 15).

Second, although logic is not natural, it can be taught with varying degrees of success, according to personality, cognitive profile, and so on. Multiple developmental psychology studies since Piaget have shown that our cognitive system can only become proficient in logical analysis later on, and with the correct training.

when does critical thinking fully develop

Third, if parents train children from ages five to nine to make more or less complex logical deductions, no deep knowledge is acquired. At a young age, the cognitive system does not yet have the capacity to discern logical invariables (i.e., the ability to reproduce a line of reasoning in a variable context). 

This is why we only explain mathematical principles to children when they are 13 to 14 years old. But again parents can encourage the basics of critical thinking at an early age by promoting social factors like self-esteem. 

Logic and Brain Development

Complex reasoning predominantly takes place in the prefrontal cortex and areas of the brain devoted to language. Language development is, of course, closely linked to explicit learning, as well as to implicit stimulation. But reasoning requires more than just language skills. The prefrontal cortex carries out what are known as executive functions. It controls concentration, planning, decision-making, and many other functions. These allow us to break down complex tasks into a series of simpler tasks. Reasoning requires a strategy that breaks things down. The prefrontal lobe is a cerebral zone that only matures neurologically after the age of 20.  Logic is neither natural nor easy. Its development requires a comfortable handling of language and the capacity for problem-solving in the prefrontal cortex. Where are we now? Where do we want to go? How can we get there?

Metacognition​

2. everyday reasoning.

Despite the fact that young children may not be able to grasp logical concepts, they still employ everyday forms of reasoning in both their use of language and in problem-solving and decision-making. It is from out of these capacities that critical thinking can begin to develop at this age.

As is readily apparent, communication via language is not logical. Natural language does not conform to a formal logical structure. It is contextual, whether we are talking about comprehension or expression. If someone says: “If I had a knife, I would cut my steak,” most people would understand that having a knife makes it possible to cut the steak. However, in formal logic, the sentence means that if I had a knife, I would be obliged to cut the steak. Logical language is systematic and obligatory. But a child learns to speak and to understand in a pragmatic and contextual, not logical, fashion.

Although their logical reasoning skills are undeveloped, young children can argue and express opinions. Parents should encourage them. Even though a child’s argument will tend to be based on emotion, the practice can help build a critical perspective and confidence.

Certain communication problems result from an overly rigid logical rigor, as in the case of people with Asperger’s syndrome, a type of high-functioning autism. Paradoxically, human communication only works because it is not a purely logical linguistic system. This is one of the reasons why automated translation between languages has been a thorn in the side of artificial intelligence experts since the 1970s.

Logical Proof and Factual Proof

Most real-life problems that we have been grappling with since infancy cannot be formally resolved by logical deduction .

Decision-making is based on a complex mix of different elements:

the cognitive processing of a situation and/or argument

intervention, conscious or unconscious, from our memory of similar past experiences, our preferences, and our personality in the broad sense

our emotions

This is how a child can choose between two toys or how an adult chooses between buying and renting an apartment. People with ultra-logical cognitive tendencies won’t have enough factors for their reasoning to work with, and may be incapable of making a decision—and therefore, incapable of taking action.

when does critical thinking fully develop

Neurological studies, since those undertaken by Antonio Damasio in the 1990s, have shown us that decision-making processes and emotional processes are intimately linked , from both neurophysiological and behavioral perspectives.

Pure logic, besides often producing unfortunate results in the real world, can be a hindrance in a highly complicated universe where decisions require managing multiple factors. This is the main reason why artificial intelligence is only now starting to see results, despite the fact that information technology has been in use since the 1940s.

Computer engineers have needed to overcome their grounding in logical, mathematical, and hypothetical deduction, and to incorporate developments in cognitive science and neurology. Algorithms now operate more like children. That is to say, they make random decisions, analyze and memorize the outcomes in order to progress, and then correct themselves by discerning both the invariables and the contextual variables. This is called deep learning. 

Children cannot rely too heavily on logic, but they are still able to express opinions based on their experiences, intuitions, and emotions.

This is also how children between five and nine years old operate. They solve many problems and make many choices, without being able to demonstrate (in the purest sense of the word) why their conclusions and choices were correct.

Between the ages of five and nine, therefore, children cannot rely too heavily on logic. However, they are still able to to express opinions based on their experiences, intuitions, and emotions. To do this, they need to practice, have good self-esteem, and feel esteemed by others in order to believe they have the right, the desire, and the energy to put their critical thinking to use. In other words, they need to exist as a thinking and acting subject whose capacities are recognized by others.

At this age, children are able to argue based on things they have experienced and knowledge they have acquired at school or at home, from books, television, or the internet, or by talking with their friends. They are also able to argue with their “heart.” They assume that their emotions are arguments themselves. 

For example, a child might consider that we shouldn’t eat meat because innocent animals shouldn’t have to die. The child’s empathy is the crux of their argument and the strength of their insistence will often be proportional to that of their emotions.

3. Preparing Kids to Think Critically

Parents or guardians can foster critical thinking skills in children from an early age. First, it’s important to understand the basics of how children learn to think and how a child’s mind differs from that of an adult. Critical thinking in their early years prepares children for life’s challenges and allows them to live a productive life.

How to teach critical thinking to your child

Here are four ways you can support your child’s early cognitive development and put them on the path to becoming critical thinkers. Teaching critical thinking may seem daunting, but having a primer on the particular needs of a child can help you better approach this important task.

when does critical thinking fully develop

1. Encourage children not to see everything as centered only on them by involving them in discussions on an array of topics, including current affairs.

Contrary to popular belief, from the age of five—and sometimes even earlier—children like to be involved in discussions, provided they are not drowned in technical vocabulary or formal logic . They also need to feel that adults are interested in what they are saying and that they are being listened to. Adults need to learn to step away from the role of educator and engage children at their level.

It is highly important for the development of critical faculties that children see their thoughts on the world are accepted. By taking those thoughts seriously, we are taking our children seriously and accepting them.

For example, ask five-year-old children whether Santa Claus exists and how they know. Listen to their arguments: they saw Santa at the mall; they know their Christmas presents must come from somewhere. Contradicting them or breaking down their worldview would be a grave mistake. It would fly in the face of our knowledge about cognitive development, and it would disregard their emotional need for this belief. Paradoxically, we need to let children formulate their own ideas and worldviews, namely through dreaming and imagination. In this way, they will grow happy and confident enough, in time and at their own pace, to move on to more mature ideas.

2. Value the content of what children say.

With encouragement, children will want to express their thoughts increasingly often, quite simply because they find it pleasurable. A certain structure in our brains, the amygdala, memorizes emotions linked to situations we experience. We are predisposed to pursue experiences and situations which induce pleasure, be it sensory or psychological. If a child puts energy into reflection in order to convince us that aliens exist, and we then dismantle their arguments and dreams, we will be inhibiting their desire to participate in this type of discussion again.

For children aged five to nine, the pleasure of thinking something through, of expressing and discussing their thoughts, of feeling language to be a source of joy, are all of far greater importance than argumentative rigor or logical reasoning.

Children debate and give their opinions. This stimulates their brain, which creates a whole host of connections, which, in turn, improve their abilities and their cognitive and emotional performance. The pleasure of discussion, of having someone listen to your ideas, releases a “flood” of neurotransmitters that promote cerebral development. An atmosphere of kindness and benevolence in which the child feels heard produces neural connections and develops various kinds of intelligence. As the child learns through debate, putting effort into reflective thought and into verbal and bodily expression, the brain evolves and invests in the future. This results from cognitive stimulation paired with  joie de vivre  that comes from being heard by others and receiving their undivided attention.

Parents should not hold back from bringing children into discussions and debates.

3. gradually, the ability to argue with pertinence, on both familiar topics of reflection or debate and new ones, will increase..

Numerous recent studies show that doing well in school results more so from pleasure and the development of self-esteem than heavy exposure to graded exercises, which can create anxiety and belittle children. Children are vulnerable and quickly internalize the labels others place on them.

In short, parents should not hold back from bringing children into discussions and debates, keeping to the principles outlined above. Also, be sure to respond to their desire to start discussions within their frame of reference and be sure to take them seriously.

4. Gradually, with time, pleasure, learning, and cognitive and emotional development, it will be possible to encourage children to argue without pressuring them through open-ended questions.

  • An opinion is the expression of an idea that is not, in and of itself, true or false. Children are empowered to express their opinions early on by all the preliminary work on building up self-esteem. “I think they should close down all the schools, so we can be on holiday all the time” is an opinion. A child of five can easily express such an opinion.
  • An argument is an attempt to convince others by offering information and reasoning. A child of eight might argue: “If we close down all the schools, we can get up later. Then we’ll have more energy to learn things better at home.”
  • Evidence are the facts we use to try to prove a point in an argument. Evidence can be highly powerful but it rarely amounts to conclusive proof. When an unambiguous proof is presented, alternative opinions evaporate, provided that one can cognitively and emotionally assimilate the perspective of the person presenting the proof. Something can be proven in two ways. On the one hand, it can be proven through formal reasoning—attainable from the age of nine upwards in real-life situations and, later on, in l more abstract situations. On the other hand, it can be established through factual demonstration. If a child claims that “you can scare away a mean dog by running after it,” proof can be given through demonstration. This leaves no need for argument.

Critical thinking exercises for kids

Hunting—for or against? For a debate like this one, with considerable social implications, focus on these concepts: 1. Teach children to distinguish between: An opinion: I am against hunting… An argument: … because it entails animal suffering and human deaths. Evidence: Hunting significantly increases the production of stress hormones (such as hydrocortisone) in hunted animals. There are around thousands of hunting accidents each year. 2. Teach children to adopt a counter-argument for practice: An opinion: I am in favor of hunting… An argument: … because it allows us to control the size of animal populations. Evidence: Wild boar populations are high and cause a great deal of damage to farmland.

New Perspectives and Overcoming Biases

4. the importance of self-esteem, understanding the importance of self-esteem, the foundation of critical thinking.

Before children can learn to analyze and criticize complicated material or controversial opinions, they need to have a strong sense of themselves. Their capacity to question external sources of information depends on feelings of self-worth and security.

The terms “self-confidence” and “self-esteem” are often used interchangeably. There is, however, a difference between the two, even if they are related. Before we can have high self-esteem, we must first have self-confidence. The feeling of confidence is a result of a belief in our ability to succeed. 

Self-esteem rests on our conscious self-worth, despite our foibles and failures. It’s knowing how to recognize our strengths and our limitations and, therefore, having a realistic outlook on ourselves.

Children need self-esteem to think themselves worthy of expressing their opinions. Parents can strengthen their children’s self-esteem by encouraging them to try new things, stimulating their curiosity, and showing pride in their accomplishments.

Self-esteem requires an ability to recognize our strengths and weaknesses, and to accept them as they are.

For example, children can have high self-esteem even if they know that they struggle with math. Self-esteem can also vary depending on context. Children in school can have high social self-esteem, but a lower academic self-esteem.

Self-esteem requires an ability to recognize our strengths and weaknesses, and to accept them as they are. Children must learn to understand that they have value, even if they can’t do everything perfectly.

Self-esteem starts developing in childhood. Very young children adopt a style of behavior that reflects their self-image. From the age of five, healthy self-esteem is particularly important when it comes to dealing with the numerous challenges they face. Children must, among other things, gradually become more independent, and learn how to read, write, and do mental arithmetic. This period is key, and children need self-confidence as well. More than anywhere else, it is in the family home that children develop the foundations for self-esteem.

when does critical thinking fully develop

Children with high self-esteem:

have an accurate conception of who they are and neither over- nor underestimate their abilities;

make choices;

express their needs, feelings, ideas, and preferences;

are optimistic about the future;

dare to take risks and accept mistakes;

keep up their motivation to learn and to progress;

maintain healthy relationships with others;

trust their own thoughts and trust others.

As parents, developing our own self-esteem enhances the development of our children’s self-esteem, as their identity is closely entwined with our own. Our children learn a great deal by imitating us. Modeling self-esteem can therefore be a great help to them. Here are some examples of what we can do:

Be openly proud of our accomplishments, even those which seem minor to us.

Engage in activities just for fun (and not for competitive reasons).

Don’t pay too much heed to other people’s opinions about us.

Don’t belittle ourselves: if we’ve made an error or if we aren’t so good at a certain task, explain to children that we are going to start again and learn to do it better.

At mealtimes, prompt everyone around the table to say something they did well that day.

On a big sheet of paper, write down the names of family members; then, write down next to everyone’s name some of their strengths.

5. Promoting Self-Esteem

The most important thing of all in the development of young children’s self-esteem is our unconditional love for them..

Children must feel and understand that our love will never be dependent on their actions, their successes, or their failures. It is this state of mind that allows them to embrace the unknown and to continue to progress despite the inevitable failures that come along with learning new skills.

To promote healthy self-esteem in children, parents must strike a balance between discipline and encouragement.

Developing Self-Esteem

But be careful not to let unconditional love prevent the imposition of authority or limits. Instead of developing their self-esteem, the absence of limits promotes the feeling in children that they can do no wrong and renders them incapable of dealing with frustration. It is necessary to establish limits and to be firm (without being judgmental). The desired result is only reached if effort and respect are taken seriously.

Self-esteem means loving ourselves for who we are, for our strengths and our weaknesses, and it is based on having been loved this way since birth.

Advice: How to promote the development of a child’s self-esteem

As parents, we have a big influence on our children, particularly when they are young. Here are some ways to help build up children’s self-esteem:

Praise children’s efforts and successes. Note that effort is always more important than results. 

when does critical thinking fully develop

  • Don’t hesitate to reiterate to children that error and failure are not the same thing. Show them that you’re proud of them, even when they make mistakes. Reflect with them on how to do better next time.

Let children complete household chores; give them a few responsibilities they can handle. They will feel useful and proud.

Show children that we love them for who they are, unconditionally, and not for what they do or how they look.

Let children express their emotions and inner thoughts.

Assist children in finding out who they are. Help them to recognize what they like and where their strengths lie.

Encourage them to make decisions. For example, let them choose their own outfits.

Invite them to address common challenges (according to their abilities and age).

Pitfalls to avoid

Avoid being overprotective. Not only does this prevent children from learning, it also sends them a negative message: that they are incapable and unworthy of trust.

Don’t criticize them incessantly. If we’re always making negative comments about our children, and if we show ourselves to be unsatisfied with their work or behavior even when they’re doing their best, they will get disheartened. 

If children don’t act appropriately, stress that it is their behavior, rather than their personality, that must change. For example, it is better to explain that an action they may have done is mean, rather than that they are themselves mean.

Always be respectful towards children. Never belittle them. What we say to our children has a great impact on their self-image. 

Show them we’re interested in what they’re doing. Don’t ignore them. We are still at the center of their universe. 

Don’t compare them to their siblings or to other children their age. (“Your four-year-old sister can do it!”) Highlight how they are progressing without comparing them to anyone else.

Risk-Taking

6. the role of emotions, understanding the role of emotions in the development of critical thinking.

Young children may develop skills in language and argument, and benefit from a level of self-esteem allowing them to stand their ground and explore the unknown. Nonetheless, the development of their critical faculties will still be limited if they haven’t learned how to manage their emotions.

Emotions appear in a part of the brain called the  limbic system , which is very old in terms of human evolution. This system develops automatically at a very early stage. But very quickly, children experience the need to rein in the spontaneous and unrestricted expression of their emotions. These emotions are, of course, closely connected to basic relations to others (and initially most often to one’s parents) and to cultural norms. 

Emotions are an important part of children’s cognitive development, but if emotions become overwhelming they can be counterproductive. Parents should help their children learn how to express their feelings calmly and prevent emotions from becoming a distraction.

The prefrontal lobe contains the greatest number of neural networks that simultaneously regulate the scope of conscious emotions and their expression in verbal and non-verbal language, as well as in behavior. From the age of five or six, children start their first year of primary school, where they are forced to sit for hours on end each day. They must also listen to a curriculum designed more around societal needs and expectations, rather than around the desires and emotions of children. Frontal lobe development  enables the inhibition of urges and the management of emotions , two prerequisites for intellectual learning and for feelings of belonging in family and society.

The ability to manage emotions has a two-fold constructive impact on the development of children’s critical faculties.  First, it enables children to override their emotions, so they may focus their attention and concentrate. This is essential for both cognitive development in general and their argumentative, logical, and critical skills.

Management of emotions also allows us to feel settled and to convince and influence others when we speak. Paradoxically, children learn that, by managing their emotions (which is initially experienced as repression), they can have an impact on their peers, make themselves understood, and even be emulated. The pleasure they derive from this reinforces the balance between spontaneity and control, and both pleasure in self-expression and respect for others will increase. Self-esteem will therefore progress, also allowing the child to assert his or her will. 

when does critical thinking fully develop

Development of the critical faculties will benefit from a heightened level of self-esteem. But it’s important to remember that this is a balancing act.

If family or social pressures excessively inhibit emotional expression, feelings of uniqueness and self-worth are compromised. In this case, even with otherwise normal (and even excellent) cognitive development, children’s critical faculties can be impeded. A child won’t truly become an individual and the development of his or her critical faculties will therefore be stunted. Such a child is like a mere cell, rather than a whole organ. This lack of individuality is found in the social conventions and education systems established by totalitarian regimes. Highly intelligent, cultured, logical people can, under such regimes, remain devoid of critical thinking skills.

Emotion is the psychological motor of cognition. But in high and uncontrolled doses, emotion can override cognition.

Conversely, if children’s emotions and expressions of emotion are badly managed or not curtailed at all, they will come to see themselves as almost omnipotent. The consequent behavior will be mistaken for high self-esteem . In reality, cognitive and intellectual development will be dampened due to a lower attention span caused by poor emotional management. Logical and argumentative skills will be less developed and what may appear to be “critical” thinking will, in fact, be nothing more than a systematic, unthinking opposition to everything. 

when does critical thinking fully develop

Critical thinking without cognitive and intellectual development does not truly exist. Real, constructive critical thinking requires listening, attention, concentration, and the organization of one’s thoughts. The development of these faculties itself requires good emotional management, which must intensify from around the age of five or six, in order to strengthen learning skills and social life. Above all, parents should not try to snuff out a child’s emotions. Emotions are what give children vital energy, the desire to learn, and the strength to exercise self-control. Emotion is the psychological motor of cognition. But in high and uncontrolled doses, emotion can override cognition.

7. Managing Emotions

How to help our children to control their emotions.

Our emotions are a part of who we are: we have to learn to manage and accept them. In order to help children manage their emotions, we must set limits (for example, by forbidding them to waste food or lie). However, setting limits on their behavior does not mean setting limits on their feelings.

We cannot stop children from getting angry even if they are forbidden from acting on that anger rather we can coach children in controlling their reactions. Sending them to their rooms to calm down will not prevent them from being upset and frustrated. On the contrary, by conveying to them the idea that they must face their emotions alone, we encourage them to repress their feelings. When children repress their emotions, they can no longer manage them consciously, which means they are liable to resurface at any moment.

Parents should not ignore or simply silence their children when they act out or are overcome with emotion. They should work with them on strategies for coping and discuss how they can more calmly and productively express their emotions.

An angry child is not a bad person, but a hurt person. When children lose control over their emotions, it is because they are overwhelmed.

These outbursts, when our children seem to have totally lost control of themselves, can frighten us as parents. Indeed, if children habitually repress their emotions, they become unable to express them verbally and rage takes over.

Failing to acknowledge children’s emotions can prevent them from learning to exercise self-control.

Advice: How do children learn to manage their emotions?

Children learn from us. When we yell, they learn to yell. When we speak respectfully, they learn to speak respectfully. Likewise, every time we manage to control our emotions in front of our children, they learn how to regulate their own emotions.

To help children manage their emotions, we should explicitly explain how to do so and discuss it with them.

Even older children need to feel a connection with their parents to manage their emotions. 

when does critical thinking fully develop

When we notice our children having difficulties controlling their emotions, it is important to reconnect with them. When children feel cared for and important, they become more cooperative and their feelings of joy cancel out bad behavioral traits.

The best way to help children become autonomous is to trust them and to entrust them with tasks and little challenges.

An angry child is not a bad person, but a hurt person. When children lose control over their emotions, it is because they are overwhelmed. Controlling their emotions is beyond their capacities at that particular moment in time and emotional control is something that they’ll build gradually as they mature.

If we continue treating them with compassion, our children will feel safe enough to express their emotions. If we help them to cry and let out their emotions, these feelings of being overwhelmed will go away, along with their anger and aggression.

Is it important to teach children specific language for expressing emotions?

Of course it is! But don’t try to force children to voice their emotions. Instead, focus on accepting their emotions. This will teach them that:

There is nothing wrong with emotions—they enrich human life.

Even if we can’t control everything in life, we can still choose how we react and respond. 

When we are comfortable with our emotions, we feel them deeply, and then they pass. This gives us the sensation of letting go and of releasing tension.

If we actively teach these lessons—and continue to work on resolving our own emotions—we will be happy to find that our children will learn to manage their feelings. It will eventually become second nature to them.

Emotional Management

8. critical thinking and social life, taking account of social norms and peer groups.

No child grows up in a vacuum. As they develop, children internalize many of the norms and ways of thinking that are dominant in their families, social lives, schools, and society more broadly. Parents should be aware of the positive and negative influences these different spheres can have on their children. They should know what they can do to expose their children to norms that will foster healthy and independent thinking.

It seems that the right, even the responsibility, to think for oneself and to exercise one’s critical faculties has become increasingly tied to notions of dignity and individuality. More and more we see factors that have historically determined who has the “right” to be critical—age, origin, gender, level of general knowledge, or other implicit hierarchies—fade in importance. 

Thus, it is becoming more and more common for students (with disconcerting self-assurance) to correct their teachers on aspects of history or other issues that are matters of fact. This raises some important questions, notably regarding the role of the educator, the goals of education, and the relationships between generations. 

Critical thinking is a positive social norm, but it requires the support of background knowledge and genuine reasoning skills. Without them, critical thinking can become an illusion.

Parents should balance their encouragement of children’s argumentative skills and self-expression with an emphasis on intellectual rigor.

Our society encourages critical thinking from a very early age. We have insisted on the fact that, for young children, although intellectual rigor is difficult to attain, it is crucial to develop self-esteem and self-affirmation. But we have also seen that from around the age of eight, it is necessary to move towards teaching them basic reasoning skills.

The risk of making the “right to critical thinking” a social norm from a young age is that we lower intellectual standards. If the encouragement of children to think critically is not paired with intellectual progress in other areas, critical thinking is rendered a mere simulation of free thought and expression. This is as true for children as it is for teenagers or adults.

The entire population may feel truly free and have high self-esteem. However, if the intellectual rigor that comes with arguing, debating, and reasoning, is missing from children’s intellectual and social education, the people will be easily manipulated. Giving our children the freedom to exercise their critical faculties must be paired with the demand for intellectual rigor and linguistic mastery, without which “critical thinking” would offer the mere illusion of liberty.

Striking a balance:

For parents today, it is a matter of striking a balance between fostering critical thought from an early age, in spite of gaps in knowledge and logic, and developing our children’s cognitive faculties and knowledge base. Without these faculties of listening, attention, comprehension, expression, argument, and deduction, critical thinking is an illusion, a pseudo-democratic farce. This  can lead to a society plagued by ignorance and vulnerable to barbarism.

when does critical thinking fully develop

On the other hand, we cannot simply slip back into old social conventions whereby children were told to simply keep quiet and learn their lessons passively. The only thing this approach ensures is that the child won’t become a troublemaker.

What is needed is an approach that harmonize advances in philosophy and psychology, which consider children as fully fledged individuals, on the one hand, with an understanding of the intellectual immaturity of this child, on the other.

Disagreeing in a civilized manner, in the end, allows us to agree on what matters most.

when does critical thinking fully develop

With the help of an affectionate, attentive, but also sometimes restrictive and guiding parent—who is at once intellectually stimulating, indulgent, and patient with the child’s needs—early development of self-affirmation and critical thinking becomes compatible with growing intellectual aptitude.

This intellectual aptitude is crucial to a healthy social life as well. People lacking this intellectual maturity cannot even disagree with each other productively; they lack the ability to discuss subjects worthy of critical interest, as well as the social and cognitive skills of listening, argument, and logical deduction. Disagreeing in a civilized manner, in the end, allows us to agree on what matters most.

Consider this discussion between two eight year olds.  – “I saw a show on TV yesterday that proved that aliens really exist. Tons of people have seen them, and they’ve found marks left by flying saucers in the desert!” – “But there’s no real evidence. Those clues and eyewitness accounts weren’t very specific. Different witnesses described the aliens in very different ways—some said they were little green men, while others said they were big with glowing eyes. And the marks from UFOs could have been formed by strong winds.” – “Oh, so you think you’re smarter than the scientists on TV, is that it?” One child declares that a TV show they saw proves the existence of aliens. He or she takes it for granted that what we see on TV is true. The second is educated into a norm that calls claims into question and demands evidence. The first child doesn’t understand the second, because, to him or her, seeing it on TV is proof enough. From this point onward, the discussion can only go in circles. In this case, different social or family norms are incompatible.

Independent Thinking

Case Study 1

Metacognition.

Already at a young age children can begin to gain perspective on how they reason.  One good way to help them foster this metacognition is by pointing out the variety of different methods available for solving a particular problem. By, for example, seeing the multiple different methods available for solving a math problem, children can begin to think about their own thought processes and evaluate various cognitive strategies. This will gradually open up the world of reasoning to them. They will begin to pay more attention to how they solve problems or complete tasks involving reasoning, instead of focusing only on answering correctly or completing the task. 

when does critical thinking fully develop

How do children calculate 6 x 3, for example? 

There are several ways:

They could add 6 + 6 + 6;

They could recall that 6 x 2 = 12, then add six more to get 18;

They could simply memorize and recall the answer: 18;

They could draw a grid of 6 by 3 units and then count how many boxes are in the grid.

Or they could use one of various other techniques…

Our culture values accurate and precise results but tends to pay little attention to the route taken to arrive at those results. Yet, if children are aware of their train of thought, they will be in a better position to master the technique—to perfect it to the point where they may even decide to switch to another technique if they need to increase their speed, for example. That is why it is important to help children understand the method they are using to the point that they can explain it themselves.

In helping their children with schoolwork or other projects involving reasoning, parents should ask them to explain themselves, make explicit the steps they’re taking to solve a particular problem, and discuss the advantages and disadvantages of their method and alternative methods. The result will be a much deeper understanding not only of the particular task at hand, but also of the practice of reasoning itself.

Case Study 2

Logical proof and factual proof​​.

At this stage, we can begin to introduce rudimentary logical concepts and distinctions. In everyday conversation, children have already begun using what we might call “natural logic.” They may, for example, get in arguments, like the one below, in which they draw conclusions based on premises. When children present these types of arguments, parents can intervene to teach basic logical concepts and ask children how a given conclusion might be proven or disproven. 

One distinction appropriate to teach at this age is that between logical proof (proof that draws logical conclusions from certain premises) and factual proof (proof that uses actual facts to prove or disprove a given statement). The following anecdote provides the opportunity for such a lesson.

William and Eve, two children walking their dog in the park, are having a conversation about Labradors:

— “There are two kinds of Labradors—black and golden,” declares William.

when does critical thinking fully develop

— “That’s not true; there are also chocolate Labradors,” replies Eve. “My friend Adam has one.”

— “Well, his dog must not be a Labrador then,” William says.

How might we interpret this conversation?

In terms of logical proof, if Labradors are either black or golden, Adam’s chocolate “Labrador” cannot be a Labrador. That is a logically formulated proof. The reasoning is valid. It is the basic premise, William’s initial declaration that there are only two kinds of Labradors, that is false. It is, therefore, possible for William to draw a false conclusion even though his logic is technically correct.

In terms of factual proof, if we can prove that the chocolate-colored dog has two Labrador parents, we can factually prove that William’s premise is wrong: there are at least three types of Labrador.

There are many opportunities like this one to begin to make explicit the logical steps involved in everyday conversations with your children and to show them that they are already using logic, even if they may not know it. This serves to get them thinking about their own thinking, and it makes the topics of logic and reasoning less intimidating.

Case Study 3

What is bias.

A bias is a simply a preconceived and unreasoned opinion. Often biases are formed due to upbringing, larger societal biases, or particular subjective experiences. They exist in many forms and can persist into adulthood unless a child builds a firm foundation in critical thinking and reasoning.

How to overcome bias

The following anecdotes demonstrate how parents can use everyday events to help their children better understand and relate to perspectives outside their own. In order to think critically, children must be able to imaginatively and empathetically put themselves outside their own experiences and perspectives. Children thereby begin to come to terms with the limitations their own upbringings and backgrounds necessarily impose on them.

This is a vital part of metacognition since it allows children to see themselves, their attitudes, and their views as if from the outside. They become better at overcoming biases, prejudices, and errors in thinking. This process also enables them to entertain the perspectives of others and thereby engage in argument and debate in the future with more charity and nuance. Finally, it encourages them to seek out new experiences and perspectives and to develop intellectual curiosity.

In this first anecdote, a child learns to broaden her horizons through an interaction with another child whose experience is different from her own. In the second, a child learns that his attitude toward particular objects can depend strongly on the context in which they are experienced. 

Overcoming Bias Example 1: Fear of Dogs

Jane is eight years old and lives in a small village. Her parents own several animals, including two Labradors. 

Jane’s cousin Max is nine and a half and lives in central Paris.

Max is always happy to visit Jane, and they play together outside, dreaming up adventures and climbing trees. But he is terribly afraid of Jane’s big dogs; whenever they come near him, he screams at the top of his lungs and runs indoors to hide. Jane finds this funny, calling her cousin a “fraidy cat” and devising ploys to lure Max close to the dogs

Jane does not realize that, unlike her, Max is not used to having animals in his daily environment. She interprets his attitude exclusively from the viewpoint of her own experience.

when does critical thinking fully develop

What would you do if you were Jane’s parents?

At the dinner table, Jane’s mom asks her to stop teasing Max and explains that he is not used to animals because he lives in different circumstances than she does.

She asks Max to tell them what it is like living in the city. Max talks about his daily life and, notably, how he takes the metro by himself to school in the mornings, two stations from home.

The blood drains from Jane’s face: “You take the metro all by yourself? I could never do that, I’d be much too scared of getting lost.”

Her mom says to her: “You see, Jane, you fell into a trap—thinking that your cousin was just like you. We are all different. You need to remind yourself of that in the future because it’s easy for you to forget!”

This focused discussion has given Jane the opportunity to overcome her own egocentrism by realizing that she and Max inhabit different worlds. She, therefore, realizes that even though Max is scared of dogs (whereas she is not), he is capable of things that intimidate her, like taking the metro alone. This allows her to re-examine her way of reasoning through a “meta” example of her own ideas about the world, eventually leading her to change her attitude toward her cousin.

As parents, we should look for and take advantage of opportunities to open up our children to new perspectives, especially with respect to unexamined biases they may have against peers or outsiders. They will gradually learn to identify and guard against the tendency we all have to generalize recklessly from our own limited experience. Moreover, they will develop the capacity to see things from other perspectives and interests outside their own narrow sphere.

Overcoming Bias Example 2: Fear of Nettles

Josh has recently been on a field trip with his class. Before a hike, the teacher warns the students to steer clear of the nettle plants in the area  These “stinging nettles” can cause a nasty itching and burning rash. 

A few days later, at dinner, Josh finds that his parents have prepared a nettle soup . Boiling water makes the nettles safe to touch and eat.  But he refuses to eat it, since his experience tells them to keep nettles as far away from his body as possible— especially his mouth.

Josh vehemently refuses to try the soup at first and insists on having a frozen pizza instead. But his parents are firm with him and show him that the soup poses no danger by eating it themselves. Finally, Josh relents and tries the soup. He finds that it causes him no harm, and, much to his surprise, he actually enjoys it.

Children who do not know that nettles are safe to eat formulate their prejudice against the soup based solely on their experience, which is limited to the nettle’s irritant qualities. 

when does critical thinking fully develop

These kinds of learning experiences can be good moments for parents to point out to their children how they may falsely generalize their own limited experiences and how those experiences can produce unwarranted biases. These prejudices may stop them from trying out new things that may very well enrich their lives. 

Case Study 4

Developing self esteem.

Climbing Esther and Ali, both five years old, are at a playground, looking at a climbing wall designed for five to 10 year olds.

when does critical thinking fully develop

Esther goes over to the wall, looks at it, and touches the climbing holds. She starts climbing, pulling herself up with her arms and putting her feet on the lower holds to relieve her arms.

When she is about six feet up the wall, Esther stops.

“Go on, Esther — you’re almost there! Come on, just one more push. You can do it!” calls out her father from the bench he is sitting on.

Esther looks at the top of the wall. She wants to make it all the way up, but her hands hurt from clutching the climbing holds. She lets go and lands on the soft covering of the playground.

“Oh—you almost made it,” her father calls out.

Ali’s father goes over to his son: “Do you want to try? Grab onto these with your hands, and then put your feet on the ones at the bottom. Then you move your hands up more, and then your feet—hands and feet… Go slowly; it’ll be tricky to start with. Check where the holds are before you start climbing.”

Ali goes to the foot of the wall and grabs the holds to see what they feel like. He starts climbing, following his father’s advice.

Ali climbs slowly. He is about halfway up the wall, far below where Esther reached. He asks to get down, and his father takes him in his arms and puts him on the ground.

 “Great job, son! That was really good for a first try! I’m proud of you. That wall isn’t easy—it’s for children up to 10.”

In these two examples of the same situation, what is the impact of each parent’s behavior on the child’s self-esteem? What will each child remember from their first try at climbing?

Esther will probably be left with a sense of failure, thinking that she disappointed her father because she didn’t reach the top of the wall on her first try. She may not be willing to try again in the future, and she may hesitate to take on other new challenges.

Even though he didn’t reach as high as Esther, Ali’s first climbing experience will likely be gratifying to him. His efforts have been recognized and encouraged by his father. He may be motivated now to make new efforts in the future, both in climbing and in other challenging new activities.

Case Study 5

Risk taking.

An important part of supporting the development of critical thinking skills at this age is encouraging children to take risks. Parents should beware of being hypercritical when their children make mistakes. They should also be proactive in exposing their children to new and potentially challenging situations. Finally, they should encourage their children to put themselves at risk in these situations, especially when it comes to putting forward arguments or answering questions. When they are (inevitably) wrong, children should be encouraged and supported rather than criticized. Being wrong should not become a source of shame for the child, but an opportunity to learn and grow. Consider the following anecdote.

Eight-year-old classmates Laura and Adam sit next to each other in a theater. Some 60 children, including Laura and Adam’s class, are on a field trip to see a historical reenactment. 

when does critical thinking fully develop

Before the curtain rises, the activity leader presenting the show asks the children: ″Who can tell me the name of the Roman emperor who conquered Gaul?”

Adam, who happens to be an avid reader of a cartoon about history, knows the answer immediately (Julius Caesar) and wants desperately to say it—but is afraid of making a mistake in front of everyone and, as a result, remains silent.

Laura hesitates. Several names spring to mind as she thinks back to what she learned in history class: Nero, Caligula, etc. Finally, a few seconds later, no longer able to restrain herself, she blurts out, “Julius Caesar!”

The activity leader congratulates her and then gets the show started.

In this situation, we see two different attitudes toward the risk of being wrong:

Adam would rather keep quiet than risk giving a wrong answer. We can deduce from this that Adam associates mistakes with something negative that could earn him disapproval or lead to him being mocked—even punished. He has thus pressured himself into thinking that only perfection is acceptable and has therefore reduced his ability to try things out.

Laura, on the other hand, would rather risk being wrong than remain silent. We can deduce from this that she does not feel shame about making mistakes; in any case, her desire to try and the excitement of taking risks outweigh the drawbacks of being wrong.

We learn through trial and erro r , which is necessary for the development of the ability to reason. Risk-taking and trial and error are vital.

Children’s environments, and notably their parents’ attitudes regarding mistakes, are determining factors in how they approach risk-taking and in whether they allow themselves to make mistakes.

Case Study 6

In addition to acquiring perspective on their own experiences and their own reasoning, children should, at this age,  begin to acquire perspective on their own emotions and to learn strategies for managing their emotions.  Without these management skills, children will be continually overwhelmed by their emotions and allow them to compromise their reasoning. The anecdote below can be used as a model to help parents guide their children in learning to express and manage their emotions, and to think clearly in spite of strong emotional reactions.

Seven-year-old Eddie is on vacation by the sea with his parents, who suggest that they all go out and take a boat to a nearby island for a few hours. They can visit the lighthouse there.

Eddie, who is busy playing with his figurines, refuses to get ready for the trip as his parents have asked.

“I haven’t finished playing! I want to stay here,” he exclaims.

when does critical thinking fully develop

“You can play with your figurines at home whenever you want, Eddy, but this boat trip is special. It’s something we can only do on vacation,” argues his mother. “Come on now, hurry up and put your shoes on, and then go and get your bag. Take a jacket as well, please—it can be cold out at sea.”

Eddie’s parents are all ready, and he still has not budged. He carries on playing with his back to them.

“That’s enough now, Eddy. Get up and get ready so we can leave,” orders his father, raising his voice slightly.

Without looking at them, Eddy bursts into tears.

“I don’t want to go on a boat! I’m scared of falling in the ocean! And what if the boat sinks? There are sharks out there! Plus I get scared of swimming if I can’t touch the bottom—if the water is too deep for me,” he says with a quavering voice.

“Oh, Eddy, why didn’t you say so before? I didn’t realize you were worried about the boat. I didn’t even think of that. But you know what? It’s normal to be scared the first time. And the ocean is daunting, that’s for sure. Listen, I’ll tell you what: let’s look at the shipping forecast together. I checked it earlier and it’s going to be a really nice day, with a very calm sea. As for swimming offshore, that’s out of the question! We’ll go swimming at our usual beach when we get back later this afternoon. And we’ll all be wearing life jackets on the boat, so there’s no way you can drown! Are you less worried now?”

“Yes… But I don’t want you to think I’m a wimp…”

“Being scared is nothing to be ashamed of! It’s a normal feeling which helps to protect us from danger. You should always say if you’re scared. I can’t always guess how you’re feeling—you’ve got to tell me!”

In this scenario, after a bit of hesitation, Eddie was able to express his fears. His parents accepted this emotion and drew on it to reassure him with clear, objective facts, helping him to understand the unfamiliar circumstances. This way he could feel completely safe on the boat.

If Eddie had not expressed his fears—because he was afraid of his parents being judgmental, angry, or perhaps even making fun of him—the situation could have taken one of the following turns:

Eddie could have categorically refused to go on the trip, and his parents would either have had to force him to come, or drop the plan entirely.

Eddie could have obeyed them without saying anything, but the trip would have been ruined by his anxiety.

Although dealing with and expressing emotions may seem far afield from critical thinking, it is a vital precondition of critical and independent thinking that children have the confidence to recognize and acknowledge their emotions. Otherwise, children will be unable to set their emotions aside in order to  consider complicated questions or scenarios in a clear and unbiased way.

Case Study 7

What is independent thinking.

What does independent thinking mean? Independent thinking is when an individual forms their own thoughts rather than just going along with what others are thinking. They apply their personal experiences, knowledge, and observations to form a personal viewpoint.

Independent thinking vs critical thinking

We can think independently without thinking critically, but we can’t think critically without thinking independently. That is, independent thinking is a precondition of critical thinking. In order to begin assessing information and making judgments objectively, we must first prevent ourselves from being unduly influenced by our peers’ views.

Example of independent thinking

In certain scenarios, children’s developing perspectives on their own beliefs, reasoning, and emotions can combine in the analysis of a challenging source of information.  The wealth of media to which children are exposed today can be overwhelming, but these media can also provide opportunities for learning and practicing the skills of critical analysis. Parents can help guide their children in these situations by prompting them with questions and asking children to make their beliefs and reasoning explicit. At this young age, preparation for independent and critical thinking need not interfere with the fantasy life of the child, as the example below shows. 

Six-year-old Tom has just written a letter to Santa Claus. Now he is watching television, flipping between channels until a show about Christmas catches his attention.

The TV presenter explains that nowadays children do not believe in Santa Claus the way they used to. Christmas has been totally commercialized. What’s more, red only became the color of Christmas due to the branding of the Coca-Cola company. 

First part of the program: “What do those concerned say?” A journalist standing outside a school asks several children their opinion. The children interviewed say that their parents have told them about Santa Claus, but that he does not really exist, at least no more than witches and ghosts do. They say that they know exactly what they are going to get for Christmas and how much it will cost. Their little brothers or sisters may still believe in Santa, but they themselves are not babies anymore. Regardless of whether they’re “naughty or nice,” they know there will always be gifts for them under the tree.

Second part of the program: “Santa Claus: salesman.” Images in the background show check-out lines in toy stores, parents with shopping carts full to the brim, others taking photos of the shelves on their phones. We see Santa Clauses of all shapes and sizes in shopping malls, day care centers, in the street, and even sitting in donkey-drawn carriages. A narrator provides statistics on the average amount spent by families on gifts, as well as the percentage of gifts purchased in-store versus online.

Finally, the presenter comes back on the screen and concludes with, “Christmas has lost its magic!” before going to a commercial break.

Tom’s father came into the room while the show was on air and has seen part of it. He can tell that his son is both confused and unsettled.

“Why do you believe in Santa Claus, Tom? What are your reasons?”

“Because he’s come every year since I was little. And because he comes at nighttime. Who else could come in the middle of the night? Because he always drinks the hot chocolate we leave him under the tree, and he eats the cookies. Because I’ve seen him more than once, near the Christmas tree at school and in stores. Because no one else could make toys for every kid and deliver them all.”

“Yes, those are very good reasons to believe in him, Tom. And what about at school? Do you talk about Santa with the other kids?”

“The big kids say the same thing as the people on the TV: that he doesn’t exist and that their parents made him up. When I told them there was no way presents could just appear under the tree overnight, they said I was a baby. I don’t talk about Santa anymore because of that.”

“I think you’re right to assert yourself and say what you really think. There’s what they say on TV, what your friends say, and then there’s your own opinion. And it’s important for you to say what you think and defend your point of view. It’s important to listen to other people too, of course, because no one is right all the time. But having your own ideas and expressing them is really important all through your life.”

What would you have done if you were Tom’s father?

Would it have been better to admit the truth about Santa Claus to Tom and contradict his beliefs and imagination? If Tom’s dad had done that, what value would his son have placed on his own reasoning? Would he have dared to defend his opinion in the future? 

During this conversation, the father chose to give weight to Tom’s arguments by giving credit to them and praising the way he expressed his personal thoughts. He did not state his own opinion on the matter, but instead focused the discussion on dealing with clashing points of view and on arguing. He hopes that Tom will now see the value in his own arguments, even if they go against what was said on the television show. Now, the next time he finds himself in a similar situation, Tom will probably be confident enough to express his own opinion on the information he receives.

The repetition of situations such as this should allow Tom’s critical thinking skills to develop. They will reinforce and strengthen his self-esteem and build his confidence in his ability to develop his own thoughts.

This situation may seem counter-intuitive. We usually associate the development of critical thinking with questioning certain beliefs, in this case the belief in the existence of Santa Claus. 

This viewpoint, though, projects our own adult understanding onto Tom. Children of his age should instead be encouraged to express themselves, to be creative in their arguments, and to believe in the value of their own points of view—rather than in the truths that are thrust on them by adults, media, or their friends.

Critical thinking: what is it and how can you develop this skill.

Founder and Head of the international IT recruitment company Lucky Hunter .

I have already raised the issue of the importance of developing emotional intelligence in previous pieces, and today I would like to talk about why critical thinking also matters for employees—especially top managers of companies.

First of all, let's define what critical thinking is. In general, it is the ability to objectively analyze events, incoming information and arguments; approach an issue from different sides; and form conclusions based on the analysis. Developing critical thinking is relevant not only for work but also for life—today we're inundated with huge amounts of information every day, and in order to be able to analyze this information and determine our position based on balanced facts, it is important to look at situations critically.

Critical thinking allows you to always soberly assess the situations taking place in your work, give an objective assessment, including your own actions and the actions of others, effectively negotiate and find the best way out of ambiguous situations. That is why large companies, when hiring employees, pay close attention to the soft skills of a candidate, especially if they are applying for top positions.

So, how can you develop critical thinking?

Practice analyzing.

Turn the events happening around you into facts. Learn to separate them from emotions. Emotions often prevent us from thinking critically, because they reduce everything to the emotional component, which cannot be relied on. Study different points of view on a specific topic. Read more, broaden your horizons and work with information—the more you “dissect” any information material, the more chances you have to get to the bottom of it.

Pay attention to self-criticism.

There should always be a certain amount of healthy self-criticism in your actions and behavior. The keyword here is healthy because it is important to maintain balance and not slip into self-flagellation. Learn to adequately evaluate yourself and your actions, and determine your strengths and growth areas. I work in recruiting, so I will give an example from my practice: In the work of a recruiter, self-criticism is vital for an objective assessment of a candidate, because, in order to evaluate others, you must first be able to objectively evaluate yourself.

Build productive communication.

If you conduct a dialogue calmly and kindly, without insults and rudeness, truly listening and hearing the interlocutor, you thereby increase the chances of getting some useful insight into the process of interaction. It can give you the opportunity to look at the situation from a new angle and come to a conclusion that you would not have come to otherwise. Therefore, the ability to conduct effective, productive communication also affects the development of critical thinking.

Develop your forecasting skills.

This point is quite closely related to the first one. Analyze information and build forecasts based on the analysis, think over the likely development of events and try to answer for yourself why it will be exactly like this. Such forecasting, again, allows you to study a specific situation from different sides, get certain insights into the process and come to an objective conclusion.

Today, it's crucial for employees and managers to develop the skill of thinking critically—all you need to do is start. The result could have a positive impact on all fields of your life, both personal and professional, because a high level of critical thinking has a good effect on communication (including business). It allows you to form objective conclusions and cut off the excess of information garbage, focusing on facts and analyzing them.

A deep dive into critical thinking (part 1) – what is it and how is it taught?

when does critical thinking fully develop

Life Competencies   Adult Learners   Teens   Young Learners   Insights, Research and Linguistics  

We all agree that critical thinking is important, but there is a lack of consensus about what critical thinking is and how to approach the teaching of it. In this post, we get critical about critical thinking and look at the biases that can affect your thoughts without you even realising! 

Some believe that critical thinking skills can be generalised and applied to different contexts and subjects, and can be taught in a generic way. For example, understanding the links between ideas can be applied to any area of knowledge. Others believe that critical thinking skills can only be taught in the context of a specific subject. For example, the skills used with an opinion article (analysing the arguments, evaluating the evidence, identifying facts etc.) are different from those used with a scientific article, where the skills mentioned may not be as relevant as the application of the scientific method – establishing facts after making an observation, forming a hypothesis, making a prediction, conducting an experiment and analysing the results etc. There are also those who believe some skills are general while others are specific.  

Breaking it down

So, before we can think of how education can help students to develop this skillset, we need to define what we believe critical thinking is and how to best teach it. The general principles are related to the ability of receiving, collecting and analysing information effectively. That is: 

  • identifying links between ideas,  
  • analysing and evaluating arguments,  
  • identifying patterns and relationships,  
  • separating what’s necessary from what’s irrelevant in a discussion, 
  • identifying gaps in reasoning,  
  • and using these skills to form an argument, solve a problem, or reach a conclusion.  

Critical thinking in schools 

In schools, critical thinking is mostly treated as a general skill that can be taught in a generic way. The academic load sure makes adding the teaching of critical thinking a challenge, let alone teaching the specific skills for each subject and area of knowledge. However, there is evidence that it’s very difficult for students to transfer the skills that they apply in one context to another. This supports the idea that there are different critical thinking skills for different areas of knowledge.  

Daniel Willingham, professor of Psychology at the University of Virginia, published a paper in 2019 called ‘How to teach Critical Thinking’, which he wrote for the Department of Education in Australia. He believes that critical thinking is domain-specific – a specific skill related to a specific area of knowledge. He says that different areas of knowledge have different definitions of what it means to know something, and they apply analysis, synthesis, and evaluation in different ways.  

So, does that mean that we can’t teach it as a general skill? Well, according to cognitive scientist Tim Van Gelder, that’s not necessarily true. He wrote an article called ‘Teaching Critical Thinking: Some Lessons From Cognitive Science’. Here, he talked about 6 lessons that summarised all the insights he had while studying critical thinking. 

Without going into the specifics of the first 5 lessons, he explains that becoming an expert in critical thinking is hard and improving these skills takes time. Additionally, we need to have at least some theoretical knowledge about something to be able to think critically about it.  

Van Gelder also said that students improve their critical thinking skills faster when they learn how to present their arguments in maps. Create a visually simple way to see the connections of ideas, reasons, assumptions and objections. This is effective because it helps learners to understand how arguments are constructed.

Critical thinking must be learned 

Personally, I believe thinking critically is not natural. We can’t assume people know how to get information, understand it, question it, and use it effectively. It’s something that can be learned with life experiences and examples from the world around us. And we need to have discipline to incorporate it in our lives. I also believe that we need to have knowledge about something before we can think critically about it.  

As for teaching this honed skill, it’s important to teach students about common sense, open-mindedness, skepticism, reasoning, logic, generalisation, correlation, causality – anything that can help them to develop critical thinking skills. Students must reflect on how their opinions are formed. They should know how they connect and combine assumptions, objections, and facts to form arguments. And finally, I firmly believe that we can’t really think critically unless we are aware of our biases. They can alter our perception of reality, our judgment, and our capacity to make impartial observations. 

In part 2 of this blog, we will explore the different types of biases. What biases should you look out for? How can you avoid them? And what does this mean when applied to critical thinking? Be sure to check it out!
