What Is Critical Thinking?
Slowing down before you react. The most underrated skill in any room.
The short answer
Critical thinking is the habit of slowing down before you react — asking whether something is actually true, whether the argument actually holds, and whether you're reacting to facts or feelings.
That's it. Everything else in this module is a tool for doing that more reliably.
It doesn't mean doubting everything or arguing with everyone. It means not letting your first reaction be your final answer — especially on things that matter.
Walk the fence before you open the gate. You don't know what you don't know until you look. Critical thinking is the mental version of walking the fence — checking things out before you act on them.
When critical thinking matters most
- Someone tells you something surprising or alarming. That's the moment to slow down, not speed up.
- You strongly agree with something. We check things less carefully when they confirm what we already believe.
- You're about to share something. If you're passing information along, you're responsible for it.
- Someone is asking you to do something based on a claim. Before you act, check whether the claim is solid.
- The stakes are high. The bigger the decision, the more it deserves careful thinking.
What it is NOT
- It is not being negative or suspicious of everyone
- It is not refusing to make decisions until you have perfect information
- It is not the same as being smart — it's a habit anyone can build
- It is not arguing for the sake of arguing
The five skills this module builds
| Lesson | Skill |
|---|---|
| 2 — Question the Source | Evaluate who said it and why |
| 3 — Logical Fallacies | Recognize arguments that sound good but aren't |
| 4 — Fact vs. Opinion | Separate what IS from what FEELS |
| 5 — Your Own Thinking | Know your own blind spots |
| 6 — The Challenge | Apply all five to a real situation |
Open with a recent local example — a rumor, a news story, a community debate. Ask: What did people do when they first heard this? What should they have done first? This grounds the lesson immediately in real stakes.

Question the Source
Who said it, why they said it, and whether it holds up — every time.
The problem with information today
We live in a world where anyone can publish anything, AI can generate convincing-sounding text in seconds, and a made-up story can spread farther in an hour than a correction will in a month. The volume of information is not the problem. Knowing what to do with it is.
The SIFT method gives you a four-step habit for evaluating any source — a social media post, a news article, an AI answer, a neighbor's claim at a county meeting.
The SIFT method
AI can help you find sources. It is not a source itself. Never cite "AI told me" as evidence for a claim. Always trace AI's answers back to verifiable, named sources. If it can't give you one, treat the claim with caution.
Red flags to watch for
- The headline makes you angry or scared. Strong emotions are a signal to slow down — not speed up.
- There's no author or no date. Credible sources name who wrote something and when.
- The URL looks almost right. Fake news sites often mimic real ones with small changes: abcnews.com.co instead of abcnews.com.
- No other source is covering it. If only one outlet has a major story, that's a red flag.
- It confirms exactly what you already believe. That's when you need to check most carefully.
Bring in two or three real examples — one reliable, one questionable, one outright false. Walk through SIFT together. The URL check and "find better coverage" steps are the ones most learners haven't tried before. Seeing them work in real time is the lesson.

Spotting Logical Fallacies
Naming them breaks the spell. Ten patterns that make bad arguments sound good.
Why this matters
A logical fallacy is an argument that feels convincing but has a flaw in its reasoning. The frustrating thing is that fallacies often sound perfectly logical — especially when delivered with confidence.
The moment you can name a fallacy, its power over you drops significantly. You stop reacting to the argument and start evaluating it. That's what this lesson is for.
Ten fallacies worth knowing
Fallacies are not always used on purpose. Most people use them without realizing it — including you, and including AI. The goal of this lesson is not to catch others in a gotcha. It's to recognize the pattern, name it, and redirect the conversation to actual evidence.
Present 6–8 real-sounding statements (draw from local issues, news headlines, social media posts). Have participants work in pairs to name the fallacy and explain what's actually wrong with the argument. The post hoc and straw man tend to spark the most discussion in rural settings.
1. "Either we approve this new road or kids won't be able to get to school." This is an example of...
2. "We planted a new crop variety and had our best yield in years — the new variety must be the reason." This is an example of...
3. The main reason to learn fallacy names is...
Fact vs. Opinion
Separating what IS from what FEELS — and everything in between.
Three categories, not two
Most people think of this as a simple split: facts are true, opinions are not. Real life is more complicated. There are actually three categories worth knowing:
| Type | What it is | Example |
|---|---|---|
| Fact | A claim that can be verified as true or false | "Daniels County has a population under 2,000." |
| Opinion | A judgment or belief that reflects values, not just data | "Daniels County is the best place to raise a family." |
| Inference | A conclusion drawn from facts — may be reasonable, but is not itself a fact | "Because the population is declining, the county may face budget pressure." |
The hard middle
Most real-world statements mix all three. A news headline might state a fact, imply an inference, and carry a value judgment — all in one sentence. The skill is separating the layers, not just labeling the whole thing.
Language signals to watch for
| Opinion signals | Fact signals |
|---|---|
| should, must, ought to, best, worst | according to, data shows, the study found |
| I think, I believe, in my view | on [date], in [year], the record shows |
| clearly, obviously, everyone knows | verified by, confirmed by, measured at |
| terrible, wonderful, outrageous | increased by %, declined to, equals |
The sorting exercise works well as a group activity with printed cards. Encourage debate — especially on the inference statements, where reasonable people disagree. The goal is not always a single right answer but the habit of asking "what kind of claim is this, and what would it take to verify it?"
1. "Everyone clearly agrees this policy is a disaster." The word "clearly" is a signal that this is most likely...
2. An inference differs from a fact because...
3. Most real-world statements — news headlines, public comments, social media posts — are...
Thinking About Your Own Thinking
The hardest lesson — and the most valuable. Knowing your own blind spots.
Why this lesson is the hardest
Every other lesson in this module is about evaluating things outside you — sources, arguments, claims. This one is about evaluating what's happening inside you. That's harder. But it's also where the biggest gains are.
Our brains take shortcuts. They have to — we make thousands of decisions a day and can't think deeply about all of them. Those shortcuts are called cognitive biases, and they affect everyone. Including you. Including the smartest people you know.
Five biases worth knowing
Knowing about bias doesn't make you immune to it. But it gives you a pause point — a moment where you can ask: Am I evaluating this based on evidence, or am I responding to something familiar, comfortable, or threatening? That question changes outcomes.
Three questions to ask yourself
- Would I evaluate this claim the same way if it came from someone I disagreed with?
- Am I looking for reasons this is true, or am I actually testing whether it's true?
- What would it take to change my mind on this? If nothing could, that's worth noticing.
This lesson works best with low stakes, relatable examples. Ask participants to share a time they changed their mind about something — not a political issue, but anything. What made them change? That story usually contains a bias they overcame. Celebrate it. That kind of intellectual honesty is rare and worth naming.

The Challenge: Real World, Real Stakes
Apply all five skills to one real situation. This is where it becomes yours.
How this lesson works
This final lesson is a synthesis. You'll take one real-world scenario and apply every skill from this module to it — slowing down, evaluating sources, spotting fallacies, separating fact from opinion, and checking your own bias.
There's no single right answer. What matters is the process: Can you walk through each step, identify what you know vs. what you're assuming, and build a reasoned position you can actually defend?
The scenario
A neighboring county is considering a wind energy development proposal. Supporters say it will bring jobs and tax revenue. Opponents say it will damage the landscape, hurt property values, and change the character of the community. A county commissioner has received several emails and social media posts about it — some presenting statistics, some sharing personal stories, some making strong predictions about what will happen if it's approved or rejected.
Apply the five skills
| Skill | Questions to ask about this scenario |
|---|---|
| Slow down | What's my gut reaction? Am I reacting to a fact or a feeling? |
| Question the source | Who's providing the statistics? What do they gain from the outcome? Can I verify their numbers? |
| Spot the fallacies | Are any arguments using fear, false dilemmas, or personal attacks instead of evidence? |
| Fact vs. opinion | Which claims are verifiable? Which are predictions? Which are value judgments about what the community "should" be? |
| Check your bias | Do I already have an opinion on wind energy? How is that affecting how I'm reading each argument? |
After working through those five questions, write a short paragraph: Based on what I can verify, here is my current position — and here is what I'd need to see to change it. That paragraph, with the reasoning behind it, is critical thinking in action.
A note on changing your mind
If you go through this exercise and end up with a different position than when you started — that is not a failure. That is critical thinking working exactly as intended. The willingness to follow evidence rather than defend a starting position is one of the rarest and most valuable intellectual habits a person can have.
If a student says "I changed my mind during this exercise because of what I found" — celebrate it loudly. That kind of intellectual honesty is rare and worth honoring. It signals the whole module has landed.

2. Someone says: "If we allow one wind turbine, the whole county will be covered in them within five years." This is most likely a...
