You should my wife (a surgeon who originally studied to be a psychiatrist) about how the DSM (book on standard diagnosis) from the early 70s is far better than any of the current crap.
She now stays far away from any of that junk and sticks to intestines!
The intestines have far less dirt in the engine than either psychology or psychiatry as they are practiced in the mainstream. There are always exceptions, and some have been pure genius in helping wounded people live fully, such as Alice Miller's brilliant work on psychological child abuse by parents. But they are a statistical minority, IMHO.
