Common sense is not common, maybe because critical thinking is not taught in schools.
And now, in the age of AI—when everything is served to us at the click of a finger—we need these skills more than ever.
Think about it: we all know the algorithm serves us what we’re most likely to interact with… so how are we ever supposed to be exposed to different viewpoints?
Actually, forget that.
Even when we’re just scrolling mindlessly, when was the last time any of us stopped and thought, “Wait, is this even the full picture?” Or is it just enough information to push a certain narrative?
Exactly.
Which is why, now more than ever, kids—and honestly, even we adults—need to equip ourselves with critical thinking skills.

30+ Critical Thinking Exercises
1. Practice First-Order vs Second-Order Thinking
Skill Developed: Consequence Analysis
First- and second-order thinking, coined by Howard Marks for investing, applies to everyone. First-order thinking is instinct—your gut reaction. Second-order thinking steps back, considers the ripple effects, and forms a wiser response.
For example, if someone asks, “Want to go out to eat?” your first thought might be, “Yes, sounds fun!” But second-order thinking pauses: “Do I want to spend money tonight? Will I be tired later? Or maybe I just want a quiet night at home?” It’s about thinking one step beyond the obvious.
The more you notice these patterns, the sharper your decisions become. Keep a journal: each day, reflect on one choice—was it first-order? How could second-order thinking have changed it? With consistent practice, thoughtful decisions become second nature.
Play this fast and slow thinking game to sharpen your thinking.
2. Identify Logical Fallacies in Arguments
Skill Developed: Argument Evaluation
Spot the sneaky tricks in reasoning so you’re not fooled by smoke and mirrors.
a. Getting to know the fallacies
Learn the classic traps like circular reasoning, straw man, and false dilemmas so you can call them out fast. Practice them with your friends and family, or reflect on where you may have used these fallacies yourself.

3. Play the Doubting vs Believing Game
Skill Developed: Perspective-Taking
Both the doubting and believing games were introduced by Peter Elbow in his book ‘Writing Without Teachers.’ While they were meant for writing, they work just as well for anything in life that requires critical thinking. The key is to play both—one after the other—so you get as complete a picture as possible.
The believing game
First, understand what the other person is saying. Then go a step further—try to understand their intentions, motivations, and the ideas shaping their thought process.
The doubting game
Next, switch gears. Now you actively look for flaws. Question the argument, look for inconsistencies, and use logical fallacies as a guide. You can even question their motives and intentions.
Let’s look at a real-life example
You come across a reel where an influencer talks about this “amazing” juice—how it keeps them refreshed and hydrated, boosts their energy, and helps them stay active and fit.
- Believing game: Okay, maybe there’s something here. It could be packed with nutrients, maybe it’s replacing junk drinks, maybe it genuinely helps them feel more energized.
- Doubting game: But is this actually proven? Or just good marketing? Are they being paid to say this? Is the “energy” just sugar? And is this working for them—or would it even work for you?
Same situation. Two ways of thinking. And somewhere in between—that’s where better decisions happen.
4. Use Socratic Questioning to Break Down Ideas
Skill Developed: Analytical Thinking
Socrates first introduced this style of questioning in the 5th century, and it’s just as relevant today. The idea is simple—start with an open mind and ask open-ended questions to truly understand the other person. Then, process what’s being said and follow it up with another question that goes one step deeper. You can even turn this inward and apply it to your own thinking. For example,
You think, “I should buy this—it looks really good.”
- Why do I think it’s good?
- Is it actually useful, or do I just like how it looks?
- Do I need it right now, or am I just in the mood to buy something?
- What will I gain from this a week from now?
Same thought. But each question takes you one layer deeper.
5. Apply the Six Thinking Hats Method
Skill Developed: Perspective Shifting
Slip on different “hats” to see a problem from every angle. Developed by Edward De Bono, 6 thinking hats is a technique that involves putting on six thinking hats to explore an idea completely. The hats are:
a. White Hat: What do I know about this topic? Is there anything else that I need to know?
b. Red Hat: What’s my gut feeling about it?
c. Black Hat: Think about whether there are any risks associated with it.
d. Yellow Hat: Explore opportunities and any pros associated with it.
e. Green Hat: Can we think outside the box and creatively explore more possibilities about it?
f. Blue Hat: Now that we have thought all of the above, what’s the best way to go forward?
6. Map Cause-and-Effect Chains
Skill Developed: Consequence Mapping
This critical thinking exercise is perfect for visual learners (not sure which type your child is? Check out our guide on learning styles and how to identify them).
At its core, this technique helps you trace the domino effect of actions—so surprises don’t catch you off guard later. Instead of jumping straight into a decision, you slow down and map it out.
Start by creating a simple flowchart of the decision you need to make, and then branch out into all the possible consequences you think you may face. Think of it as turning “What will happen?” into something you can actually see.
For younger children, you can keep it playful and simple—just a few options and outcomes. For older kids, you can go deeper, adding layers like “What might happen next?” or “How would that make you feel?”
And here’s the fun twist: this isn’t just for decision-making. You can also use it to break down everyday situations—like understanding a story, predicting what happens next, or even reflecting on something that already happened. It turns thinking into a visible, engaging process.
Example of the cause-and-effect chain
flowchart TD
A[Decision] --> B[Immediate Action]
B --> C[First Consequence]
C --> D[Next Effect]
D --> E[Final Outcome]
C --> F[Alternative Path]
F --> G[Different Outcome]7. Understand Correlation vs Causation
Skill Developed: Evidence Evaluation
Correlation is when the occurrence of one thing is linked to another, whereas causation means that one thing directly causes the other to happen. For example, hot weather causes people to feel hot. Because of that, they eat more ice cream and go swimming. So, eating ice cream and swimming often happen together (correlation), but they don’t cause each other; the hot weather is the real cause behind both (causation).
As an exercise, you or your child can look at everyday situations—like eating your favorite food and feeling happy—and ask: are these two things just happening together, or is one actually causing the other?
Try making a simple list of examples and discuss them together, questioning each one. This helps build the habit of pausing, thinking deeper, and not jumping to conclusions too quickly.
8. Run Thought Experiments to Challenge Assumptions
Skill Developed: Hypothesis Testing
Thought experiments are all about exploring an idea in its entirety. Start by asking yourself “what if…” and then follow that thought all the way through, without stopping halfway. There are many experiments you can try, and one of the most famous is the trolley problem, where a trolley is rushing down a track at full speed.
In its classic form, five people are tied to the track ahead. You’re standing near a lever that can divert the trolley onto another track—but there’s one person tied to it. What do you do? Do nothing and let five people be harmed, or pull the lever and actively choose for one person to be harmed instead?
The point isn’t to find the “right” answer. It’s to stretch your thinking—to notice how your choices change when the situation changes and to understand the values behind your decisions.
This is where critical thinking starts to take shape. When you walk through a thought experiment, you’re learning to slow down your judgment, look at a situation from multiple angles, and question your own assumptions. You begin to see that problems aren’t always black and white—there are trade-offs, consequences, and hidden factors to consider. Over time, this builds the habit of thinking deeper, asking better questions, and making more thoughtful decisions in real life—not just in imaginary scenarios.
9. Spot Cognitive Biases
Skill Developed: Bias Detection
The human brain is built for speed. It uses mental shortcuts to make quick decisions, which is helpful in everyday life. But these shortcuts can also lead to cognitive biases—systematic ways our thinking gets distorted.
For example, confirmation bias makes us focus on information that supports what we already believe. Anchoring bias makes us rely too heavily on the first piece of information we hear. Availability bias makes us judge how likely something is based on how easily examples come to mind, not reality.
These biases aren’t “bad thinking”—they’re just fast thinking that sometimes goes off track. The skill is learning to spot them.
Activity: Bias Detective Game
Pick a recent opinion you had (about a person, news story, or decision). Now answer:
- What did I already believe before forming this opinion?
- Did I only look for evidence that supported it? (confirmation bias)
- Was my judgment influenced by the first number/fact I heard? (anchoring bias)
- Am I overestimating something just because I’ve heard about it recently or often? (availability bias)
Rewrite your opinion after challenging at least one bias.
10. Use steelmanning to strengthen opposing arguments
Skill Developed: Argument Evaluation
Steelmanning is an exercise wherein you try to build the strongest argument against your belief. So, for example, if you believe ‘The sky is blue,’ you try to build a strong argument like ‘The sky is not blue; it’s the atmosphere.’ The blue we see is only because of how light scatters through it, and under different conditions, that blue can disappear.
The point is not to prove yourself wrong, but to make sure your belief can actually hold up when it is challenged properly.
11. Break Arguments into Premises and Conclusions
Skill Developed: Logical Analysis
Any argument has two parts: 1. a claim, 2. a justification of the claim. Your job is to separate the two to see if the justification actually makes sense.
For example, a fellow parent tells you, “More screen time makes kids less focused, so screens should be limited.”
Claim: Screen time should be limited.
Justification: More screen time is making kids lose focus.
Now ask yourself: Is this causation or just correlation dressed up as truth? What’s being ignored in between—sleep, routine, content type?
Another example, a friend says: “This cake has unique plant-based ingredients that let you indulge and still lose weight, so it’s a healthy dessert option.”
Claim: This is a healthy dessert option.
Justification: It has plant-based ingredients.
Now break it down. “Plant-based” sounds convincing, but it says nothing about calories, sugar, or overall impact. And “lose weight while indulging” is doing the heavy lifting without proof. The justification doesn’t actually carry the claim. Your next step is to be aware of arguments that come your way and practice breaking them up to see if it still holds up.
12. Evaluate Evidence: Anecdote vs Data vs Research
Skill Developed: Evidence Assessment
“I started waking up at 5 AM and became more productive.” (anecdote)
“In a survey of 1,000 people, 68% of early risers say they feel more productive.” (data)
“In a controlled experiment, researchers adjusted people’s sleep schedules and found productivity stayed the same when sleep duration was equal, suggesting wake-up time alone isn’t the cause.” (research)
Now the difference matters. An anecdote is one person’s experience. Data shows a pattern in many people. Research tests whether that pattern actually holds when other factors are controlled.
Critical thinking is knowing not to treat all three the same. It’s asking: Is this just one story? Is this a pattern? Or has this actually been tested? Instead of jumping to conclusions, you pause and weigh the strength of the evidence before deciding what to believe.
Activity: Take a common claim (like “waking up early makes you more productive”) and write one anecdote, one data point, and one research-style version. Then ask: which one explains why, not just what?
13. Ask “Compared to What?” for Better Judgments
Skill Developed: Comparative Analysis
“A $5 drink is expensive.”
On its own, that feels true.
But compared to what?
Compared to a $1 homemade drink, yes. Compared to a $12 café drink, it suddenly looks reasonable.
Same statement. Different comparison. Completely different judgment.
In fact, many marketers use this to push you towards buying more. They don’t change the product—they change the reference point. A higher-priced option placed next to what they want you to buy makes it feel “reasonable.” A “was $100, now $60” label makes $60 feel like a deal, even if you never intended to spend that much.
Critical thinking is simply noticing this pattern instead of absorbing it—asking what the comparison is before you accept the judgment.
Activity:
Take any statement that includes a judgment (like “expensive,” “good,” “bad,” “better”). Now rewrite it twice by adding two different comparison points. Notice how the meaning of the original statement changes depending on the comparison.
14. Practice Probabilistic Thinking (Think in % Likelihoods)
Skill Developed: Probabilistic Reasoning
Probabilistic thinking is an exercise where you assign a likelihood to your belief instead of treating it as certain. So, for example, if you believe “this will work,” you think of it as “this has a 70% chance of working,” and then consider what factors could increase or decrease that likelihood.
This matters because once you assign a %, you are forced to consider uncertainty, alternative outcomes, and missing information instead of assuming a fixed result. Once you assign a %, you are not just accepting a belief; you are evaluating how strong it actually is.
Activity:
Take any prediction you make today and assign it a % likelihood. Then list one factor that could increase it and one that could decrease it.
15. Use Counterfactual Thinking (“What If” Scenarios)
Skill Developed: Scenario Analysis
Take any event that has happened recently and play with “what if” scenarios. For example, what if I had woken up half an hour earlier today? Then actually try to answer it—what would have changed, what would stay the same, and what might have unfolded differently.
This simple exercise sharpens critical thinking because you’re not just replaying events—you’re examining cause and effect, spotting hidden assumptions, and understanding how small decisions can lead to very different outcomes.
16. Play The Facts or Opinion Game
Skill Developed: Information Evaluation
“That shirt does not look good on you.” That one line is enough to spiral a lot of us into our insecurities.
But is it actually a fact… or just an opinion?
This is where we often get stuck. We treat someone’s personal view as if it is a universal truth. But not everything said about us is a fact that applies to everyone.
Facts are things that can be proven. Opinions are personal judgments shaped by taste, mood, and preference. Play this fun fact-or-opinion game with your kids to sharpen their thinking.
17. Test Assumptions by Trying to Disprove Them
Skill Developed: Hypothesis Testing
Play devil’s advocate on your own thoughts to find weak spots. Take a belief or idea you’re holding onto and ask, “How could this be wrong? What evidence would go against it?”
This sharpens critical thinking because you’re not just defending your thinking—you’re stress-testing it. You start spotting gaps, questioning what you took for granted, and building stronger, more reliable conclusions.
18. Apply Systems Thinking to Understand Interconnections
Skill Developed: Systems Thinking
See the whole web, not just the single thread, to spot patterns. Instead of zooming in on one moment or one cause, widen the frame. Ask: what led to this, what is happening alongside it, and what might follow?
Think of it like pulling one string and watching what else moves. A small change rarely stays small—it connects to habits, people, timing, and environment. When you start asking “what else is connected to this?” you begin to notice hidden links. When you ask, “What might this affect next?” you start tracing ripple effects.
For example, your child is cranky in the evening. The “single thread” view is: they’re just in a bad mood. But the “whole web” view asks: Did they nap late? Eat less at lunch? Have more screen time? Miss outdoor play? Now look ahead—if they’re cranky, bedtime might get delayed, sleep might be poor, and tomorrow morning could start the same way.
Now you’re not just reacting to one moment—you’re seeing a pattern and understanding what’s feeding into it and what it leads to. That shift is what strengthens critical thinking.
19. Detect Emotional Reasoning in Decisions
Skill Developed: Emotional Awareness
Check if feelings are driving choices more than facts. When something feels strongly right or wrong, pause and ask: Am I reacting to the situation, or to how I feel about it?
For example, you get a message from someone that sounds a bit short, and you immediately feel offended and think they’re upset with you. That feeling is real—but is it the full picture? They could just be busy, distracted, or typing quickly. When you separate the feeling from the facts, the situation often looks different.
This sharpens critical thinking because you learn to notice when emotions are taking the lead. Instead of letting them decide for you, you step back, question them, and make choices based on a clearer, more balanced view.
20. Separate Signal vs Noise in Information
Skill Developed: Information Filtering
Not all information deserves equal attention. Some of it actually helps you understand what’s going on (signal), and some of it is just distracting, irrelevant, or misleading (noise). The challenge is learning to tell the difference.
Filter out the static and focus on what really matters. When you’re taking in information, ask: what here is actually useful for making a decision? What is just an extra detail that doesn’t change anything?
For example, you’re reading reviews before buying something. A few people complain about delivery delays, while most reviews talk about the product quality. If your decision is about whether the product is good, the delivery complaints might be noise, while consistent feedback on quality is the signal.
Over time, this helps you avoid getting pulled in every direction. You start focusing on what actually influences outcomes, instead of getting stuck on information that just feels important but isn’t.
21. Practice Delayed Judgment (Wait Before Concluding)
Skill Developed: Reflective Thinking
Before reacting to a slight from a co-worker or a friend, pause. Don’t react immediately. Almost all thinking—critical thinking included—flies out the window when we respond impulsively. That brief pause gives your mind the space it needs to observe, analyze, and choose a wiser response.
22. Test Analogies (Where Do They Break?)
Skill Developed: Comparative Reasoning
Analogies are everywhere. They make things easier to understand by comparing one thing to another. But just because something sounds similar doesn’t mean it actually works the same way.
That’s where things can go wrong.
Imagine someone says, “The brain is like a computer.”
Sounds reasonable, right?
Both process information. Both store data.
So… are they the same?
Not quite.
A computer follows fixed instructions. The brain adapts, feels, forgets, rewires, and learns in messy, unpredictable ways. The analogy helps you understand one part—but if you stretch it too far, it starts to break.
This is where critical thinking comes in.
You ask:
- Where does this analogy work?
- And where does it stop making sense?
Activity Idea: “Break the Analogy” Game (Ages 5+)
- Step 1: Give your child a simple analogy:
“A teacher is like a YouTube video.” - Step 2: First, ask: How are they similar?
(Both explain things, both help you learn.) - Step 3: Then ask: Where does this break?
(A teacher can answer your questions. A video can’t. A teacher knows you. A video doesn’t.) - Step 4: Try a few more fun ones:
- “A heart is like a pump.”
- “Friends are like followers.”
- “The internet is like a library.”
End with: Does the analogy help… or does it hide something important?
23. Use Inversion Thinking
Skill Developed: Strategic Thinking
Sometimes the fastest way to understand something is to flip it.
Instead of asking, “How do I make this work?”
ask, “What would make this fail?”
Imagine you want to build a strong friendship. You could list what to do—be kind, listen, share.
Or you flip it: What would ruin a friendship?
Ignoring, lying, not showing up.
Now the path becomes clearer.
This is inversion thinking. You look at the opposite to see the truth more sharply.
Activity Idea: “Flip It” Game
- Step 1: Pick a goal: “Do well in a test.”
- Step 2: Ask: What would make you fail?
(Not studying, rushing, not reading questions.) - Step 3: Flip each one.
(Revise, slow down, read carefully.)
End with: Was it easier to see what to do by first seeing what not to do?
It usually is.
24. Make Fermi Estimates for Better Reasoning
Skill Developed: Estimation & Quantitative Reasoning
Not every question needs an exact answer. Sometimes, a good enough estimate gets you much closer to the truth than a random guess.
Imagine someone asks: How many people are in a mall right now?
You don’t know the exact number. But you can break it down.
How many floors?
How many shops per floor?
How many people per shop?
You start building the answer piece by piece.
This is called a Fermi estimate. You take a big, unknown question and turn it into smaller, guessable parts.
This is critical thinking in action. You’re not stuck because you “don’t know.” You’re reasoning your way forward.
Activity Idea: “Guess Like a Scientist”
- Step 1: Ask a fun question:
“How many cookies are eaten in our home in a month?” - Step 2: Break it down:
Cookies per day × number of days - Step 3: Make rough guesses together and calculate.
- Step 4: Compare with reality (check your pantry or track for a week).
End with: Was your estimate close? What would you change next time?
The goal isn’t being exact—it’s learning how to think your way through the unknown.
25. Apply Occam’s Razor to Choose Simpler Explanation
Skill Developed: Explanatory Reasoning
Overthinkers, this one’s for you.
How many times have we built a full story in our head… when the answer was simple?
You can’t find your keys.
Maybe someone moved them. Maybe something unusual happened.
And then you find them… right where you usually keep them.
This is Occam’s Razor. When there are many explanations, start with the simplest one—the one that needs the fewest assumptions.
The goal is simple: check what’s most likely before you jump to what’s dramatic.
This is where critical thinking steadies you. You pause and ask: Am I adding extra layers here?
26. Explain Reasoning Step-by-Step (Think Aloud Method)
Skill Developed: Metacognition
We often rush to answers without showing how we got there.
But real thinking becomes clearer when we slow it down and explain each step.
Imagine solving a problem in your head, but instead of jumping to the answer, you say your thinking out loud:
“I see this… then I notice that… so this might mean…”
Each step builds on the last.
This is the think-aloud method. You make your reasoning visible, one step at a time.
This is where critical thinking becomes structured. You’re not just giving answers—you’re showing the path to the answer.
And when the path is clear, mistakes are easier to spot.
27. Apply Bayesian Thinking to Update Beliefs
Skill Developed: Belief Updating
We don’t think in fixed truths. We think in updates.
Something feels true today. Then new information shows up tomorrow. The question is—do we adjust, or do we hold on tightly to what we already believe?
Imagine you believe a restaurant is great. Then you hear a bad review. Then another. Then you try it yourself and notice the food is average.
Each new piece doesn’t erase the old one. It adjusts your understanding step by step.
This is Bayesian thinking. You start with a belief, then keep updating it as new information comes in.
28. Use Outcome vs Process Thinking for Reflection
Skill Developed: Reflective Evaluation
Someone got the highest marks.
Was it luck? Or was there a strategy behind it?
Sometimes we only look at the result and stop there. But the result alone doesn’t explain everything.
A student may score well because they prepared consistently. Another may score well because the questions happened to match what they already knew. Same outcome, very different paths.
This is where outcome vs process thinking comes in. You don’t just look at what happened. You also look at how it happened.
This is critical thinking in reflection. You separate luck from effort, and result from reasoning.
Activity Idea: “Result or Reason?”
- Step 1: Say a situation:
“Someone won a game.” - Step 2: Ask: Was it skill, practice, or luck?
- Step 3: Break it down together:
Did they practice before? Did something unexpected help them win? - Step 4: Try another example where someone tried hard but didn’t win.
End with: Does the result always tell the full story?
29. Decode Hidden Motives Using Transactional Analysis
Skill Developed: Behavioral Analysis
People don’t always say what they mean directly. Sometimes the message is on the surface, and sometimes it’s underneath.
A child says, “I don’t care,” but actually wants attention. A friend says, “It’s fine,” but feels disappointed.
This is where transactional analysis helps. You look at what is said, and what might be driving it underneath: needs, fears, or expectations.
Activity Idea: “What’s Behind the Words?”
Say this: “I don’t want to play.”
Now pause and explore what might be going on underneath it.
Maybe they’re tired. Maybe they feel shy. Maybe they just want a different game.
Try a few more everyday lines like this and see how many different meanings you can find behind the same sentence.
The point is simple: words are only the surface.
Do words always show what someone is actually feeling?
30. Ensure you don’t fall for the power of a single story
Skill Developed: Perspective Broadening
As they say, there are three sides to a story: your side, their side, and what actually happened in between.
But most of the time, we only hear one version—and treat it like the full picture.
A single experience starts to define everything. One awkward interaction becomes “they are rude.” One disappointing visit becomes “that place is bad.”
This is the power of a single story. When one moment quietly expands into a full judgment.
This is where critical thinking expands perspective. You pause and ask: Is this the whole story, or just one frame of it?
Activity Idea: “One Moment vs Whole Picture”
Pick a simple scenario:
“Someone didn’t respond when called.”
Now explore:
- What are 2–3 different reasons this could have happened?
- Which ones are based on facts, and which are guesses?
- What would you need to know to be sure?
End with: Can one moment describe the whole person or situation?
