What It Means When AI Says 'I'm Not Sure'

Sometimes AI admits it doesn't know — that's actually a good thing.

5 min · Reviewed 2026

The big idea

If AI says 'I'm not sure' or 'I don't know,' that's honest! It's better than making something up. When AI is unsure, you definitely need a real source.

Some examples

'When was the last earthquake in my town?' AI: 'I don't have current info.'
'Who won the school spelling bee?' AI: 'I don't know that.'
'How tall is your dad?' AI can't know that.
'What's tomorrow's weather?' AI can't see the future.

Try it!

Try to ask AI 3 questions where it might say 'I'm not sure.' Notice what kinds of things AI doesn't know.

Practice this safely

Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about uncertainty, not to let it make the decision for you.

Ask AI to explain uncertainty in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "What It Means When AI Says 'I'm Not Sure'" and ask for two possible next steps plus one reason each step might be wrong.
Check honesty against a trusted source, teacher, adult, expert, or original document before you use it.
