I've noticed this blind spot — people pay more attention to a good answer than a good question — in forums. Specifically forums with post-level voting like reddit/twitter/hn. There are many cases where a downvoted question has an excellent answer in response, sometimes the best post in the whole thread. I think people perceive the questioner as annoying, obnoxious, petulant, or some such and the answer as "correcting" their foolishness. The key is recognizing that, while the answerer had to follow through, they got the perfect layup by the questioner.
I realized this a while ago so I just invert the bias: If every excellent answer was set up by a good question, I take the question to be good by definition if the answer is good, even if the question seems mediocre from my perspective. The question has to have some kind of inner spark that makes the answer possible or fuel that makes the answer brighter, something in it that enabled the answer to shine, whether I happen to see it or not. Practically this means that whenever an answer post is good enough to upvote, I seek out the parent question post for consideration and evaluate it generously.
