The Confident Guesser

Here is a weird thing about AI chatbots. They always sound sure of themselves. Even when they are completely wrong. Even when they are making stuff up.

Scientists call this a hallucination, which is a fancy word for when an AI invents a fact that is not true. The AI is not lying on purpose. It does not know it is wrong. It is just guessing the next most likely thing to say, and sometimes the guess is fake.

When AI is most likely to be wrong

Exact numbers (dates, populations, sports scores)
Names and who said what
Very new things (the AI may not know about last week)
Things only a few people have written about online
Lists that feel too neat or too long

Warning signs

The answer feels too perfect or too fast
The AI names a book, article, or website you cannot find
Two AIs give you different answers to the same question
The AI gets super specific with a number it has no way to know

Your fact-checking toolkit

Look up the fact on a site you trust (Wikipedia, a real news site, a real book)
Ask the AI how sure it is, or to cite its source
Ask a second AI the same question and see if they match
If it is important, ask a real human who knows the topic

AI is the most confident liar I have ever met, and it does not even know it is lying.
— A middle school librarian

The big idea: AI sounds sure even when it is wrong. Always check the important stuff. Treat AI like a smart friend who makes things up sometimes.
