I wonder how much the source content is the cause of hallucinations rather than anything inherent to LLMs. I mean if someone posts a question on an internet forum that I don't know the answer to, I'm certainly not going to post "I don't know" since that wouldn't be useful.
In fact, in general, in any non one-on-one conversation the answer "I don't know" is not useful because if you don't know in a group, your silence indicates that.
