How it works
1 · Mark the claims
Each round shows a short fictional AI answer and a set of evidence cards. Mark every claim: Supported, Unsupported, or Not enough evidence.
2 · Check your answers
Hit Check my answers to see each verdict — the correct call, the exact evidence card that decides it, and where you went wrong. False alarms cost you.
3 · Learn the tells
Read What gave it away? for the tricky claims: vague numbers, confident tone with no source, and citations that say something adjacent — but not the claim.
Under the hood
What this teaches
AI can sound confident while being wrong. Fluency and confidence are generated the same way truth is — the tone tells you nothing. A hallucination reads exactly like a fact until you check it.
A citation existing doesn’t mean it supports the claim. The sneakiest hallucinations borrow real details — a real journal, a real prize, a real study — and then say something the source never said. Always ask: does this source actually say this?
“Not enough evidence” is a real answer. When the evidence only covers half a comparison, or the sources themselves disagree, the honest verdict isn’t a guess — it’s admitting you can’t tell. That skill works on every AI answer you’ll ever read.
