user1908: Suppose that question X and question Y are both identification-request questions, and suppose that it turns out that in both cases, the thing to be identified was anime Z. Should question X be marked as a duplicate of Y (or vice versa)?
For example, the question https://anime.stackexchange.com/questions/9949/a-comedy-manga-about-a-guy-who-protects-his-house-from-a-girl-that-comes-from-th was marked as a duplicate of the earlier question https://anime.stackexchange.com/questions/4405/comedy-manga-with-a-16-year-old-boy-from-a-poor-family; both questions were looking for the manga Sakuratetsu Taiwahen. In this case, the answers were the same, but the questions were different. 
Contrast this with the question https://anime.stackexchange.com/questions/6721/who-is-this-character, which was closed as a duplicate of What anime is this winking girl from? - in this case, the questions themselves were obviously the same, so I think we all agree that this closure-as-duplicate was correct and appropriate. This is not the type of situation I am talking about in this question.
Relevant discussions elsewhere:

Why would VTC as duplicate be appropriate for a story identification question? at meta.scifi
Should story-identification requests that turn out to be about the same story be marked as duplicate? at meta.scifi


user27: 
Here's my take on this, it doesn't represent some community consensus but my own personal opinion.

Yes.
There are two cases of closing as a duplicate:

The question was exactly asked before, generally posted again by the same author.
The question is answered elsewhere on the site. 

Identification questions with anime already identified match the second rule, so I argue that they should be closed as duplicates.
It can be preferable to add details not found on the original question from the asked duplicate back to the original, to make the question more complete.
