@darkling@mstdn.social @cstross@wandering.shop It's the wrong question. The correct question is, "What proportion of answers to programming questions given by programmers who understand the language and the question are wrong."

Ask almost ANY question of someone who doesn't actually understand the question or the subject, and the answer you receive is overwhelmingly likely to be wrong. (This is doubly true in America, where it seems to be considered almost a mortal sin to ever be heard to say "I don't know".)
