Since this site is more subjective than some, we occasionally get answers that are solely based on personal opinion or make claims with no justification/references. Even subjective questions should invite facts (instead of opinions), so such answers are less than ideal.
What should we do with these answers? Here are a few options (though feel free to propose alternatives not in this list):
- Just leave them alone and let them be downvoted/ignored
- Flag them for immediate deletion
- Flag them for the application of a post notice (e.g. "citation needed"), with deletion being the next course of action if the answer is not filled out
If you'd like some ideas on how this is handled on other sites, I refer you to a Skeptics FAQ.
