For me it's more of is Sun going around the Earth, or the Earth around the Sun types of questions. Something very basic. I.e. is there a sex addiction or not? Is homosexuality a "disease" or not? I mean you do have whole movements like anti-psychiatry movement that basically are in total opposition to everything that psychiatry claims.
I can go to a psychiatrist and persuade him/her that I have a bipolar disorder. Or that I'm schizophrenic, or depressive. And that's because there is no way for psychiatrists to know. You can talk all day long about all types of brain imaging tests that could reveal the diseases. But if that in fact was true then psychiatry would use the tools in the diagnostic process. If nothing else then at least to shut up guys like me who laugh at that "science".
Do you think that I can't go to 3 doctors and persuade each of them that I have a psychiatric condition and that they wouldn't give me a diagnosis?
