Ninefingers asked: Ok, one from me. A question comes in and receives a highly up-voted answer that is technically wrong according to one or two members of the community. What action as a moderator, if any, do you take?
AviD answered: If it came in via our community, even if it's wrong, it is a viable answer. That said, commenting and downvoting are the tools here
AviD noted: I had a meta post on that a while back....
AviD continued: If it came with a migrated question, then in most cases the actions would be the same. In extreme cases, e.g. if the answer was migrated with already high nmber of wrong-votes, there has been a case that I encouraged the asker to close the original, and re-ask the question anew in the correct community.
AviD concluded: I did take some heat for that decision, but I stand by it.
- Jeff Ferland noted: I think that's a very fair thing and again in the realm of power-user (though the unspoken diamond word power...). We know that other sites do have cases where answers get upvoted with info we know to be wrong... and for that the general action of mods has historically been to dissuade migrating questions late.
Rory Alsop answered: Initially - wait for flags if unsure. Then discuss in chat. Then close, and be aware that it may be re-opened, altered, migrated or whatever. This happens a bit, especially on migrated-in questions
Rory Alsop continued: Flagging and voting are still key here
Jeff Ferland answered: You weigh in if you know it, you stay away if you don't. If you get somebody like @ThomasPornin being the one who points out that it's technically wrong and you know by reputation that he is the somebody who is a master of their domain, you point that out. If it's civil, this isn't a moderator role -- it's a user role. The mods on SO aren't running around fixing technical comments on code.
M'vy answered: Moderators are not here to correct the community but lead it. If the answer has at least some information which is correct, there is nothing to do, and the poster earned the reputation. However topic that shall be off-topic, or not suited to the site shall be removed. By the way, we can pinpoint the user that think answer are wrong to propose a new one or improve the existing.
Scott Pack answered: Much as @JeffFerland said. I see a moderator's role being that of responding to incidents and guiding the culture. In this situation, I do see it as, largely, a normal user issue to deal with. The problem, however, comes into play when you're dealing with a dangerously incorrect answer.
Scott Pack continued: In that situation I feel as though a mod may need to step in and possibly delete the post depending on how egregious it is. I do, however, feel that is should be strongly guided by user flags.
Hendrik Brummermann answered: This is a problem we often have with questions that are migrated from other sites such as StackOverflow and StartUps. I think this situation can be dealt with by normal users in most cases by adding comments.
Hendrik Brummermann continued: In some cases I have edited an answer to add a note at the beginning pointing out that this answer was migrated from another side and therefore was likely not written with security in mind. There may be cases which justify moderator involvement, but those have to be looked at on a case by case basis.
nealmcb answered: I agree with @JeffFerland that moderators aren't here to somehow "fix" technical errors, but judicious use of comments and discussion can usually deal with those issues also.
Graham Lee answered: Thankfully this problem has been rare on security.stackexchange (compared with, for example, security questions on stackoverflow), though I appreciate it could still happen. I wouldn't want to use my mod powers to obliterate or change the answer in case it's me that's in the wrong. I'd down vote, leaving a comment with references to explain why. I might bring it up in chat to see what everyone else thinks.
