I generally provide the source for my information. Even if I already know the answer, I will generally provide a reference on the web or in a document. If I asked an LLM, I will provide that as part of my answer, and I'll generally chip in whether the answer makes sense to me or not; in some cases I'll say that I have no clue if the LLM response makes sense.

Needless to say, I have probably not advanced as far as someone who hoards information, because companies tend to value the information hoarders, but this is just the way I'm designed to operate. I despise information hoarding.
