A lot of people (eg on Reddit) seem to believe that depression is caused by a "chemical imbalance" and that the solution is antidepressant drugs. That's a bit different from the "positive attitude" case but also something that might be disagreed with.
The drugs we have today are not a good solution. I've suffered from depression myself and have been prescribed many different drugs at times. The best match was still only a partial solution. I've read enough to know that this is pretty typical: few people get 'total remission' from depression on psychiatric drugs alone. Most have some degree of improvement, but have to try many drugs first (i.e. there's no good prediction of a drug will do to a person) and usually have at least minor side effects (i.e. the drugs are not very specific in their action).

I suggested recently that part of the problem with with LW was a lock of discussion posts which was caused by people not thinking of much to post about.
When I ask myself "what might be a good topic for a post?", my mind goes blank, but surely not everything that's worth saying that's related to rationality has been said.
So, is there something at the back of your mind which might be interesting? A topic which got some discussion in an open thread that could be worth pursuing?
