I was reading [this](https://movies.stackexchange.com/questions/72045/identify-a-movie-about-boys-imprisoned-after-injured-killed-a-men-with-an-hot-do) question and its answer, where OP misremembered something and when he found out the correct "thing" from the answer, corrected it. So I'm wondering, is it better to correct it or leave it as it is?

For me, I think the question shouldn't be changed to match the answer, but is there's anything in the rules/guidelines suggest one way or the other?
