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

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.

AI is not smart enough for science
AI can only know things that existed when it was trained
The student asked wrong
The discovery must not be real
What makes a question hard for AI to answer correctly?
Questions about specific people, places, or recent events
Questions with long answers

An AI answers a question about a topic you know well, but gives wrong details. This might happen because:
The AI doesn't like you
You should have asked a longer question
You asked the question in a confusing way
The AI is confident but actually wrong — which is why checking sources matters
Why do researchers recommend verifying AI answers, even when the AI sounds certain?
