Well, I too jump into threads where I think I know some part of what's being discussed.

But I'll often bookend a comment like that with points about what I don't know. And here, there are points I think someone might know - frame those as questions. But also there are point I doubt either myself or the person I'm replying to knows, frame those as problems of knowledge, statistics and so-forth.

Obviously, I think I know a general framework, that our beliefs are areas of semi-certainty bordered by heuristics, myth, ignorance and lack of awareness. But this is a belief that will often about what I or we, don't know.
