>The tradeoffs of Science vs everything else have proven to be worth it over and over.
I hate to invoke Godwin's law here but it is worth noting the key role "science" and psychiatry played in propagating the Holocaust[1]. If we're going to play the science card, we should make sure it's objective.

Edit: curious you spell Science with a capital "S"
The problem with psychiatry isn't that they aren't trying or that they're not going about it the best way that we know how. The problem is that the human mind is still too complex at the macro level to be easily testable. But Science has shown again and again that it's the best way to go about determining how reality works. We shouldn't abandon it now and prefer delusional thinking because it has a minor winner in making a patient feel better. That said, tell the patient whatever he may want to hear in the psychiatric ward. Just don't try to pass it off as legitimate outside of the mental institution.
Regarding capitalization: Sometimes I find it helpful capitalize schools of thought that embody more than just a casual set of principles. I can do some science in the lab, but not really have a lot of trust in Science as a way to live life, run society, and generally approach problem solving. I do the same thing when writing about being liberal vs being "a Liberal".
I agree this is the root problem, which is why I think psychiatry, if it wants to be a legitimate medical science, should adhere to medical ethics, i.e. primum non nocere. Otherwise, psychiatry patients are akin to lab rats.
