ChatGPT sounds as confident as a person presenting an incorrect answer. Which is ironic, since it can probably calculate how confident it is. I have included part of a transcript where ChatGPT bounces between two answers (likely the two answers it has confidence in) even though it is told that both answers are incorrect. In other cases, it insisted upon a singular answer.
(Sorry about editing out blocks. ChatGPT is verbose. I limited the removal to background material about the book.)
