On questions like this one that have a tendency to be answered by low-rep users who don't cite any sources, mods can add the following post-notice:
Want to improve this post? Provide detailed answers to this question, including citations and an explanation of why your answer is correct. Answers without enough detail may be edited or deleted.
It's a useful banner, but the issue is that the same notice is posted over answers that don't cite any sources. The wording of the notice, however, remains geared toward questions. One issue in the wording is that the 'your' implies that it's addressed to the post-owner, not any random editor. Here is a proposed rewording for the post-notice on sourceless answers:
Want to improve this answer? Add details and include citations to explain why this answer is correct. Answers without enough detail may be edited or deleted.
