The short version
Treat AI like a very fast, very confident colleague who sometimes gets things wrong. For anything that matters, ask for sources, open them, and cross-check the key facts elsewhere.
Why AI gets things wrong
An AI produces plausible text, not guaranteed truth. A confident but false answer is called a hallucination. The riskiest areas are specific facts: numbers, dates, quotes, names, laws, medical advice and web links.
The five-step check
- Spot the checkable claims. Names, numbers, dates, quotes, prices, “studies show…”.
- Ask for sources. “Give me links to where each of these facts comes from.”
- Open the links. Make sure they exist and really say that. Made-up links are a common failure.
- Cross-check. Search the key fact yourself, or ask a second AI: “What might be wrong with this answer?”
- Match risk to effort. Brainstorming needs a glance. Health, money, legal and safety need a professional.
Review your answer above. List every factual claim it contains, mark each as "well established", "uncertain" or "you may have guessed", and give a source I can open for each. If you can't source something, say so.
Common mistakes
- Trusting a tidy layout or confident tone.
- Asking the AI “are you sure?” and taking “yes” as proof.
- Forgetting that AI may not know recent events unless web search is on.
