Recently I answered a question on ELU, and later found that my answer was actually incorrect. I wasn't sure whether it was worth it to correct it, or delete since a proper answer was already chosen.

Should one delete his answer if it's found to be incorrect?

    You answer doesn't seem wrong to me. Also, there isn't an accept on that question. Did you link to the right one?

  • There wasn't an accepted question, but it got the most votes, and is on the top of the page. The comments show the OP acknowledging the answer, so I assume it as the accepted one. It was downvoted by a member saying it was incorrect, but it was actually upvoted some more now, so I'm not actually sure if it's correct or not.

  • Just an update: As I write this, Zolani13's answer is the top scorer, and the "de facto accepted" answer is now marked as accepted, though it's not even the 2nd highest scorer. (The meta question asked here is still relevant and good in general, as are the answers below. Just the details surrounding the linked-to example have since changed somewhat.)

If you wrote an answer that you found to be wrong, you could edit it to make it correct; in the case there is another answer, and your answer would become too similar to the existing one, then you can delete it. In this case, deleting it (if editing is not worth doing it) would avoid that future users, seeing it has a score of 3 (as it actually has), would think the answer is correct.
If you provide links to different resources or you quote different resources, then I would think it's worth editing it. If the text would be too similar even in this case, I would delete it.

Don't edit the answer to replace its text with a placeholder, such as "This is not longer applicable." or "Wrong answer." If you keep doing it for your answer, this would be considered vandalism of own posts. At least, it would be flagged as "not an answer," and moderators could do one of the following actions:

  • Delete your answer.
  • Revert the post to the last revision.

Between the two, it's not said the first is the preferred one, especially if moderators notice you have recently edited your post.
The other reason I would not do it is that your post could attire down-votes.


One of the goals of Stack Exchange sites is to make the internet better by providing good answers to real questions. Retaining an incorrect answer is something of a dis-service to future readers; even if it's voted down to the bottom of the page, it's still there contributing misinformation. If the correct answer has not yet been posted then you can correct yours; if it is, why add a duplicate? Just delete in that case.

I have deleted my own answers when they turn out to be wrong, or do not address the question (e.g. I misunderstood what was being asked), or (on rare occasion) when a later, better answer completely deprecates mine.

Sometimes there is valuable information in a comment thread that will be lost if you delete your answer. Something I've seen in that case is to delete the body of the answer (replacing it with something like "no longer applicable") so the comments still have a place to live. I don't know if that's considered good practice, though.

Whether you should delete any particular answer is your own judgment call, but it is certainly permitted.

  • If you change the answer text to "no longer applicable," that could be considered vandalism of own post. The answer could be flagged as "not an answer," and at that time moderators could just delete it (which would mean also comments are deleted), or revert your last edit.

    If you are willing to put in the effort, you could also preserve information from the comments by editing the question or other answers depending on where the material fits. If you're not deleting your answer at that time, once you have added the info from comments, you can flag those comments for cleanup (there is an "obsolete" option, or use the text field to explain).
