While this community for the most part is pretty good about supporting their claims with evidence, occasionally we receive an answer that makes a broad, unsupported claim. Sometimes, those posts are downvoted and ignored, but particularly when they are close to the popular view, and when on HNQs, they sometimes get sufficient upvotes to avoid that fate.
On other sites I frequent, a post with a broad, unsupported claim that is challenged would receive a post notice from a moderator indicating that the user should support the claim with evidence or else the post will be deleted. I haven't noticed that on this site, even when flagging a post which seems to qualify.
Is that something we would ask our moderators to do on this site? If so, should they be fairly aggressive about it (and use notices whenever significant unsupported claims arise, even if they might be technically accurate), or should they primarily only do so when there is a dispute about the content (or when they themselves would dispute that content, of course)?
