We've discussed answers in comments (a no-no) and answers without references (also not within guidelines).
I don't think we've discussed "answers in chat". Should the same guidelines apply, i.e. if it can't be supported by sources, should it not be posted?
If I am discussing aspects of an answer that may imply a different answer, is that a matter that should concern me? What should the policy be?
Edited to add: My question isn't about espousing nonsense theories (like the effects of "energized water on Martian exposure syndrome") - in chat (although I have no major objection to that; chat is usually an informal place.) My question concerns having a place where discussion about how to improve answers on the site can take place.
If it is prohibited in chat, there is no actual way to help each other write better answers on this site.
Most sites will tolerate some discussion of an answer, but often that results in
Please avoid extended discussions in comments. Would you like to automatically move this discussion to chat?
The inability to write basically anything except a question without giving a source (though it's a policy I wholeheartedly agree with) is a burden evident on the main site.
One option is to post a "better answer", but when an already good one exists that can benefit from just some tweaking, that seems like an unnecessary duplication of efforts. It seems reasonable that having a place without all the restrictions already on the main site might - like chat - be a good thing.
I checked Meta, but am having a problem finding what is permitted and not permitted in chat (aside from swearing, etc.)
Skeptics, a site that is very similar to Health, has no such limitations on what can be discussed in chat.
