Here's at least the second instance in which I have flagged a question as a duplicate, and the canned comment text "Does this answer your question?" elicits from the author of the duplicate question a response along the lines of "uhh, no," but it's clear they didn't bother to study the answer. I find the choice of language here to be less than optimal for the following reasons:
- To the person asking the duplicate question, this response gives the impression that the person flagging the question as duplicate is uncertain that the question already has an answer. Because the person flagging as duplicate is far more likely to be more knowledgeable about the nature of the question and answer than the person asking it, this approach tends not to elicit a careful reading of the answer that was already provided.
- Because question closure either requires agreement from several users, or a flag from a single gold tag badge user on the tagged subject, it is unlikely that such flagging would be abused or incorrectly applied to the point where the question is closed.
- The essential meaning of the response is inconsistent with the flag. When I flag as a duplicate, I am communicating not just to the original poster that I believe the question already has an answer elsewhere, but also to other community members that this is a possible duplicate worth confirming. I'm not trying to enter into a discussion or debate with the original poster about it. That's like me writing an answer to their question and then asking them if it's correct. If I wasn't sure it was right, I wouldn't have bothered to respond.
I don't know why the previous language was unacceptable and it got changed to this weaker tone, which I find unnecessarily patronizing and a bit fake. If I was unsure about whether the question already had an answer, I wouldn't flag as duplicate (see reason 2 above). I'd directly post a comment with a link suggesting the author take a look.
