The scenario: a question has been asked "does A=B?". An answer is given that is wrong. And the questioner has accepted it. My questions:
This is math so there is (for many and this particular question) a definite right or wrong answer. The difficulty could be a misuse of definitions, or a typo in calculation that goes astray, or any number of things. But how do you communicate this to the answerer in a non-confrontational way.
The 'rational' way would be to say "No, that is incorrect, here is the correct answer.". But that is inflammatory even in private, and stackexchange is pretty public. But to say 'Here is an alternate answer', or "Here is a better way to word it, by removing your 'not'", is either annoyingly postmodern or aggressively passive-aggressive.
it seems strange, in some instances, that the questioner, who is often asking out of (self-proclaimed ignorance) is the one expected to judge correctness of the answer. An approved answer tends to stop voting on other answers, even if the approved answer is wrong.
Do you have any thoughts/suggestions on either of these points?
