user43480: I came across this answer on looking at a question in the sidebar. The answer was accepted and upvoted 6 times. There is a linked study, but it is a counter example (it is cited as a demonstration of a case where the answer doesn't hold), and even so, it (the study) doesn't directly address the question or the statements made in the answer.
I've noticed a banner on some questions to the effect that an answer is not supported by sources and can be challenged. How would I request that banner for an unsourced answer?

user43480: As discussed in the comments, the resolution here is:
Users who would like to challenge an answer that doesn't have references should

downvote (this is particularly important)
leave a comment explaining the concern about references
flag as "in need of moderator intervention", with an explanation describing the lack of references and requesting a banner, (e.g. "needs citation banner", per @theforestecologist's comment)

I'd add a note that I'd encourage more users to vote on answers and challenge those without adequate references (or with references that don't support the answer). Generally, answers here are good, and many are excellent, but I'd personally like to see as much of a focus on voting on and cleaning up low quality answers as there is on voting on and cleaning up low quality questions. (Hence the bump today).
