While I love how usually quickly you can get answer on this forum, sometimes it leads to problems, when the person asking forgets/fails to ask precisely the question they want answered and someone meanwhile already answered... unfortunately not exactly on the topic that question's author had in mind.

Lets say I'd like to ask about the hair loss problems among elves:

Has there been any description of bald elf in literature?

For which I get answer that

Yes, there was an X in book Y that lost his hair after meeting the fire-breathing dragon Z

Uh, yes... it is right, but I really meant "natural baldness", so I should I now:

  • Edit my question pointing that I had in mind "natural causes" such as age - this invalidates the answer which is (apparently) frowned upon
  • Point my correction in the comment to the answer - which in turn (since not everyone reads the comments) won't stop another person from describing yet another case of elf that lost hair in accident
  • Drop the question completely and re-edit it - this would kinda put the work of people that already answered to waste.

Well, of course I should clarify everything perfectly at the first time, but after all, I'm just a human prone to make mistakes.

When you want to follow up with the author of a post, the best solution is always to leave a comment. The reason why is at the core of why we dislike edits that invalidate answers: that's the only way answerers get notified of something changing. There was a to change this back in 2009, but it never got an official response; it seems like this is a feature that's not coming in the near future, if ever.

Having said that, I don't personally think there's necessarily anything wrong with making clarifying edits to a question; it depends a great deal on the specifics of the edit, and how drastically it changes the parameters of the question.

The specific example you give, for example, is a bit drastic in my opinion; it excludes a huge number of answers (which is, of course, your intention). A better edit might have been to add:

Edit: I have a special interest in natural baldness

The idea is to narrow your meaning without excluding the efforts of prior answerers. This might feel a bit weaselly, because it is a bit weaselly, but that's the game we play.

It's also worth pointing out that "Existing answers are outdated" is a bounty reason1, though it wasn't intended for this use case:

That reason is intended to address old questions where new information may have been released that the existing answers don't address.

In this case

I don't think this specific instance (that is, Has anyone gotten married more than once in the LOTR universe?) is a good example of this policy in action; I would have answered both versions of the question (the one you posted and the one you meant to post) in exactly the same way. Likewise, I would answer both versions of your "bald elf" example he exact same way2.

However, I want to caution against narrowing down your questions, but for a different reason: you'd be surprised the things you can learn. Ideally, a good answer to a slightly overbroad question will include the answer to the question you wanted answered (and if it doesn't, you can always ask in a comment), but you'll gain a little bit of extra trivia along the way. And that's why we're really here, isn't it?

According to Meta Meta:

In general, any edit that changes the question should be rolled back, but for a question without answers, sometimes I think the OP can be given a little leeway as long as they aren't trying to get around a question ban and/or completely changing the question.

However, any edit to a question, other than clarifying the original question, that invalidates any answer should be rolled back and a comment should be left indicating what they did wrong. Sometimes it is possible to edit the question in such a way as to integrate the new info added by the OP without invaliding answers and the editor should try to make an effort to do that.


Users are encouraged to clarify and improve existing questions, if they are under-specified or otherwise incomplete. That's not the same thing as asking a new question that renders the existing answers invalid.

This meta answer suggests that the OP should ask for clarification in comments rather than by editing the question.

    This Meta topic refers to questions that very completely change the question to a new one. Though in the realm of programing that doesn't take much adjustment to warrant a completely new question. @yasskier seems to be talking about adding further clarification to a question. Which I would say every member should encourage.

  • @S.Fruggiero - It invalidated two existing answers. That's a no-no.

    @WadCheber please notice that both answers have been updated to match the REAL meaning of my question, hence the edit (that I've retracted) has't invalidated any of them.

  • @Yasskier - Your edit came before theirs did, so yes, the edit invalidated the answers. They edited their answers, so the edit was also unnecessary.

    @WadCheber and if I wouldn't edit my question (and pointing to what I really had in mind) they wouldn't edit their answers hence not really answering my intended question. And thats why I'm asking about proper procedure here on meta.

  • @Yasskier - See my answer. You should ask for clarification in comments rather than by editing the question.

  • @WadCheber fair enough, but like I've mentioned it might lead to multiple answers in the future pointing to incorrect unedited question.

    @Yasskier - Then you should just accept the fact that you're not allowed to edit questions in such a way that existing answers become invalid.

In the event that the OP makes the change and it keeps with the spirit of the question and does not result in a very different question all together, then leave the edit so it best gets across the point of your question and draws out the best answers to it.

So long as the OP is the one making changes to the question to ensure they get the answer they are looking for, then I see no problems here. If someone has answered the question and then they are wrong because of your changes, they can modify their answer or pull it. The OP should only care that their question is clear and draws out the type of answers they are looking for.

The OP is welcome to modify their question by adding a remark about the further clarification they are making. Such as:

Edit: To clarify, I am looking for instances of "naturally occurring baldness".

  • I upvoted this because I like your point about the original author being the one who should make the changes. If somebody else did, the original author could comment with, "That's not what I said!" And that just embarrasses whomever edited the question. Who better would understand the author's intent than the original author?
