how do I get ChatGPT to fact-check itself?
Get ChatGPT to fact-check itself by asking something specific and checkable, not a vague “are you sure?” A vague challenge reads as social pressure, so the model often caves and changes something that was already right.
Includes side-by-side runs of the same wrong answer — one challenged with "are you sure?", one given a specific check. Only one of them catches the actual error.
