OK, I think I have to start drawing conclusions in public. Some of them terrify me, but I'll try a few of the safer ones. Thanks. Actually I've just read Broda Barnes (I was originally assuming he was a lunatic who'd confirmation-biased and placebo-effected himself to death), and his clinical observations agree pretty much with my predictions, although I'm not sure yet what I think of his theory, which isn't the same as mine.
