AIs say false things for the same reason you do

Scott Alexander at Astral Codex Ten:

I hate the term “hallucinations” for when AIs say false things. It’s perfectly calculated to mislead the reader – to make them think AIs are crazy, or maybe just have incomprehensible failure modes.

AIs say false things for the same reason you do.

At least, I did. In school, I would take multiple choice tests. When I didn’t know the answer to a question, I would guess. Schoolchild urban legend said that “C” was the best bet, so I would fill in bubble C. It was fine. Probably got a couple extra points that way, maybe raised my GPA by 0.1 over the counterfactual.

Some kids never guessed. They thought it was dishonest. I had trouble understanding them, but when I think back on it, I had limits too. I would guess on multiple choice questions, but never the short answer section. “Who invented the cotton gin?” For any “who invented” question in US History, there’s a 10% chance it’s Thomas Edison. Still, I never put down his name.
