As a Psychiatrist and long-time Slashdot reader I feel really disappointed reading the reactions of people whose oppinion in technical matters I respect a lot.
But after > 20 years of "in-the-trench" psychiatry (public and private settings) I've seen (BY FAR) more good than harm as consequence of our practice. I can say I helped a number of people, lots of them using SSRI.
We are aware of the industry and its tactics, and the wax-and-wane of science. But most of my colleagues act in good faith following procedures tested in our gold-standard double blind placebo-controlled trials.
Medicine CAN do harm sometimes, that's not new. But when you add all up, there's a net benefit.
