When ChatGPT gives me a wrong answer, and I point out that it is wrong, ChatGPT immediately apologizes, every time. I have not seen it argue that it's actually right.

I've also seen it give different answers when asked the same question in a different way. Usually, one of the answers will be correct.

It has no idea if it's answers are right or wrong. It only knows that it's putting words in a common order.
