Yes, there is discussion around what a person can do when there is a blatantly accepted wrong answer:
And so on.
However, I couldn't find a formal feature-request, so here it goes.
It sprung from a question on Database Administrators:
Note that the accepted answer is commented on multiple times, and is blatantly wrong (and is proven so empirically). It's currently being downvoted, which is fine, but it really shouldn't be at the top of the page because it is an accepted answer.
- Allow moderators to remove the accepted flag from the answer which has been empirically proven to be incorrect
- Moderators must provide a comment and a reference to an answer for the same question (in the form of a link) proving that the answer is incorrect. This provides accountability and would be made visible to other moderators and possibly high-rep users in some fashion
- The user that accepted the answer may not re-accept the answer as "the answer" unless there is an edit to the answer
Some things of note:
- The moderator doesn't have the ability to specify another answer as correct
- Yes, people can edit the answer, but one of the tenants of SO is that you maintain the intent of the original post; if the answer is blatantly wrong, changing it to be right violates this and constitutes a bad edit, IMO
It's been suggested that the answer bit is just a flag for the original poster to help them remember what helped them (emphasis mine), but that's not completely correct.
The answer bit does serve that purpose, but not only that purpose. It places the answer at the top of the page. This in turn affects SEO (given that it is higher in the page). Additionally, if another person comes across the page through an organic search and then goes with the accepted wrong answer and then experience a setback because of it, that impacts their impression of the site and it's ability to deliver information that is of benefit to them.
If that wasn't the case, then organic search wouldn't be a priority for the site (which it most definitely is).
It's also been suggested that the user change the default ordering to affect the order of the answers to find the "right" answer.
There are two reasons that this doesn't work.
First, Google gets the default ordering for indexing, so it doesn't solve the SEO issue.
Second, first-time users of Stack Overflow are given the default ordering, and seeing the big green checkbox is an instant indicator to them that it's the "right" answer, and don't bother doing the research to make sure it's right. Sure, it's easy to say "well, they want to shoot their foot off, let them" but that's fairly harsh considering the mandate of SO.
ChrisF indicated in the comments that a moderator can delete a post outright. Yes, this does solve the problem, but I think this is more egregious than removing the tick. More often than not, posts with low/negative votes serve as a bellwether showing what not to do.
- What kind of edit needs to be performed before the answer can be re-accepted? A significant edit by the original poster? An edit by someone else? I don't like the latter, given that an edit by a user other than the one who answered the question would have to change the intent of the post, which violates a fundamental tenant of SO.
- Impact of reputation on the answer that is unticked
