Worth noting here that editing has a
terrible success rate for duplicates. There's already edit guidance - the asker is asked to edit the question after the first vote or flag arrives, and this does a lot of good... But
after the question is closed, edits rarely do anything beyond clogging the reopen queue. Part of the problem here is that we don't give a lot of guidance specific to this situation to askers
when they're editing - but we
do provide this when they're asking! We'll review the data on this after its been live for a while & watch for unintended consequences. —
