Questions about this section should probably go in the open thread. Posts on psychology and/or useful advice are both welcome in Discussion.

If reading past discussion posts does not give you an idea of what is suitable, then try posting and see how people react. Also note that the stated rules and preferences are not necessarily the actual ones, so consider whatever people tell you (including this comment) with some skepticism.

I have my own opinions as to what is appropriate, but as a matter of fact it's very hard to be downvoted in a discussion post. Looking through discussion you'll be able to see that almost none of the posts are voted down. The main thing that will cause downvotes is being low quality, the subject matter is almost irrelevant.

Yes.
