The big idea
A hallucination is when AI confidently makes up facts that don't exist — a fake quote, a fake citation, a fake person. Spotting it early is the most important AI literacy skill.
How to use it
- Ask AI for a citation and check if the paper actually exists
- Ask AI for a quote from a famous person and verify it
- Ask AI to explain why hallucinations happen (next-token prediction)
- Ask AI which topics it hallucinates most on (recent events, niche people)
Try it
Ask AI for 3 citations on a topic. Check if all 3 papers exist. Report back what you find.
