Here in Canada, you basically can't say "Fuck Freud" if you're a practicing psychotherapist, as there is something in the ethics code about respecting your peers. I can say it as I didn't make it to the PHD, but it's a bit frustrating to realize the field is self-regulating and at least 25% of its members basically don't believe in the power of... evidence.

Not unrelated, epistemology classes are not mandatory, despite the field being in the rare position of accepting (or at least tolerating) several vastly different epistemological viewpoints. Kind of like studying homeopathy and epidemiology in the same program.
