I tend to think the person who can truly identify that the question is a dupe is the questioner. Not IME. It depends on whether the Q is a XY problem or if the asker is acquainted with the problem-domain. I engage with Qs on the use of a specific set of tools, and I see users pose the same problem (with incidental variation) with imprecise/vague terms or phrasing. Also, there are a couple of novice pain points for which I regularly see duplicates with similar description and terminology. I tend to think the users just didn't spend a lot of time looking through search results, if at all.
