Usually once or twice a day in the close queue, I find a question that is a PSQ (Problem Statement Question) and also a duplicate. Sometimes another reviewer explicitly links to the dupe, other times I do it myself.
My question is: what is the preferred reason to close these type of questions?
From a pedagogical standpoint I'd side with not linking dupes, as even the act of searching or clarifying what you are looking for is sometimes instructive to hone your focus. But I guess I'm asking from a more site-specific view; that is, is it somehow better for the site to either have a linked dupe or a PSQ in isolation, or are they both about the same?
