Truth Detective

You have learned so much in this module! You know how we come to know things. You can tell facts from opinions. You look for evidence. You pause before believing surprising things. You check your sources. You listen to more than one side. You are honest about what you are sure of. And you know how to check what AI tells you. Now it is time to put all of those skills together. Today you are going to become a Truth Detective.

The Truth Detective Toolkit

A Truth Detective is someone who investigates whether claims are true before they believe or share them. It sounds serious — but it is actually a lot like being a curious explorer. You ask questions, follow clues, and dig until you find out what is really going on. Here is your complete Truth Detective Toolkit — all the skills you have built in this module: Tool 1: Know how you know. Ask yourself: did I experience this directly, or did someone else tell me? How reliable is that chain of knowing? Tool 2: Fact or opinion check. Is this something that can be checked, or is it what someone feels? Tool 3: Evidence search. What clues back this up? Can you find real, observable evidence? Tool 4: Pause and question. Does this seem possible? Is it surprising enough to deserve a check? Tool 5: Source check. Who said this? Do they know the topic? Can you confirm it elsewhere? Tool 6: Hear all sides. Is there another viewpoint you have not considered? Tool 7: Certainty check. How sure are you, really? Do you have enough evidence to be confident? Tool 8: AI awareness. If AI told you this, have you confirmed it with another trustworthy source?

The Big Idea

A Truth Detective uses all eight tools — not just one or two. The more tools you use on a claim, the more confident you can be about whether it is true.

Truth Detective Case Files

  1. You are going to investigate THREE mystery claims using your full Truth Detective Toolkit. For each claim, work through as many of the eight tools as you can.
  2. CLAIM 1: 'Elephants are afraid of mice.'
  3. CLAIM 2: 'Our school cafeteria is serving pizza every day next week.'
  4. CLAIM 3: An AI helper told you that a famous person said something surprising.
  5. For EACH claim:
  6. Step 1 — Write down the claim.
  7. Step 2 — Is it a fact-type claim or an opinion-type claim?
  8. Step 3 — What evidence would you need to confirm or disprove it?
  9. Step 4 — What source would you check?
  10. Step 5 — After investigating, what do you think? Write your verdict: Probably True, Probably False, Need More Evidence, or This Is an Opinion.
  11. Bonus challenge: Use at least one real source (a book, a trusted website, a teacher) to check Claim 1 — the elephant and mouse claim. What did you find?
  12. Share your three case files with a friend or family member. Did they agree with your verdicts?

Let us walk through what a Truth Detective does with Claim 1 together. Claim: Elephants are afraid of mice. Tool 2 check: This is a fact-type claim. It could in theory be observed and tested. Good — it is the right kind of claim to investigate. Tool 4 check: Does it seem possible? Elephants are enormous animals. Mice are tiny. A little unusual — worth checking! Tool 5 check: Where did this claim come from? It is a very old folk saying that has been repeated for centuries in cartoons and stories. Tool 3 check: What does the evidence say? Wildlife researchers who have studied elephants in the wild have not found reliable evidence that elephants are scared of mice. Elephants have poor near-vision and might startle at any small, quick-moving creature — but a fear of mice specifically is not supported by strong scientific evidence. Verdict: This popular claim is likely a myth — interesting, funny, but not supported by solid evidence! Notice how the tools worked together to get there. That is what a Truth Detective does.
