"I'm not sure" — when AI says it
30-second gist~30s read
Most chatbots are built to sound confident. So when one says "I'm not sure", "I might be wrong about this", or "you should verify this with a professional", that's a real signal. Listen to it.
Especially listen if the AI is uncertain about a question you needed a confident answer to. That's the moment to not rephrase and try again.

Why uncertainty is rare
The training process pushes models toward decisive answers. Vague answers got worse ratings from test users — so the model learned to commit, even when committing wasn't honest. Uncertainty has to be deliberately tuned back in, and even then a confident-sounding wrong answer can sneak through.
The newer "reasoning" models are noticeably better at flagging genuine uncertainty than chatbots from a couple of years ago. But they're still imperfect. Treat any "I'm not sure" as informative, not exhaustive.
