Some other comments already discussed the issue that often neither A nor B are necessarily correct. I’d like to add that there are many cases where the truth, if existent in any meaningful way, depends on many hidden variables, and hence A may be true in some circumstances, and B in some other circumstances, and it’s a mistake to look for “the one static answer”. Of course the question “when are A or B correct?” / “What does it depend on?” are similarly hard questions. But it’s possible that this different framing can already help, as inquiring why the two sides believe what they believe can sometimes uncover these hidden variables, and it becomes apparent that the two sides’ “why”s are not always opposite sides of a single axis.
