I'd prefer the phenomenon be called "saying the first thing that comes to your mind" instead, because humans do that a lot as well, and that happens to produce pretty much the same failures as LLMs do. IOW, humans "hallucinate" exactly the same way LLMs do - they just usually don't say those things out loud, but rather it's a part of the thinking process. See also: people who are somewhat drunk, or very excited, tend to lose inhibitions around speaking, and end up frequently just blurting whatever comes to their mind verbatim (including apologizing and backtracking and "it's not what I meant" when someone points out the nonsense).
