This meta discussion is sort of a spin-off from this recent meta discussion about whether or not an asker's age is relevant to a question, and whether or not it should be edited out. Since the issue of age is fraught with multiple issues, I thought it would be good if we isolated this one specific issue and debated it separately here:
If two questions ask for essentially the same thing, and the only difference between them is that the asker of one question specifies they know no physics or math beyond the very basics at all, and the other is a graduate student of physics, are these two questions duplicates?
Obviously there are precisely two positions here, namely "yes" or "no" (excluding a spectrum of "yes in the following cases, no in other cases" positions, of course) which each have some issues we should address:
If yes, how should users without the understanding required for currently present answers to a question request answers suited to their level?
If yes, should requests for particular levels of explanation in a question be edited out?
If no, how finely-grained should we go here? Is "explain like I'm five" substantially different from "explain like I'm ten", or is "I'm an undergraduate physics student" different from "I'm just starting to study physics at university"? What about incommensurable qualifiers of the level of sophistication (e.g. "I'm in Xth grade" vs. "I know only basic physics", with the added bonus of not knowing Xth grade in which country)?
(I'm not seeking for a discussion of whether these incommensurable qualifiers are actual or good measures of "physics level", just what we do with them when askers make them. If it turns out we don't really care for the specified level, discussions about how to specify it are moot, anyway.)
If no, do answers that substantially miss the required level of sophistication in either direction constitute not-answers, meaning they should be flagged and deleted? What do we do if someone posts the same answer with the same level to all questions asking about the topic regardless of the specified level?
If no, is specifying a level required? If it isn't, is the question without any specified level a duplicate of either of the versions where it is specified, or vice versa?
Previous related discussion on meta (please add if you fine more!):
How should I ask a question to understand the answer I will get?, which is basically subquestion 1 here, where I wrote the sole answer with the assumption that "yes" was our site's implicit consensus as an answer to the overarching question here.
Gauging prefered expertise level for answering questions, which is more about whether any particular level of expertise is required to answer questions.
Should posts targetted at different complexity levels be marked as duplicate?, which is more specifically about the question of level in resource-recommendation questions
Respondents' consideration of the level of question, discussing whether or not answerers should respect the level requested in a question, making it similar to subquestion 4 here
Liberal definition of duplicate questions and the health of physics stack exchange., where...I'm not completely sure how to judge its relevance to this discussion.
