some LW posters are confident in both (1) and (2), some are confident in neither of (1) and (2) while others are confident in exactly one of (1) and (2)

Logically, this is tautological. I think you're saying that there don't seem to be many who are completely convinced that both (1) and (2) are untrue. I think that's right; both claims are somewhat plausible.

Curious: do people prefer "neither A nor B" or "neither of (A and B)"?

The problem is that "confident in" has an ambiguous negation. "not confident in A" is different than "confident in not-A".

Right, but the quoted text is consistent, so, if you grant me that "some" means >=0, my original statement would have been correct. Of course, "some" implies >0, which I missed.
