An example apart from how Psychiatry profits from inserting itself into the legal system - we have society-wide acceptance of the chemical imbalance theory of depression - still without evidence. Because this model is a billions-of-dollars money pipeline for drug companies, who take the bad PR on the nose, and ...psychiatrists.
I have written much less than I could, but I find almost everything about psychiatry - it's influences from Freud, etc. to be problematic.
I know there's no chance of swaying anybody personally invested in the field towards this viewpoint. It's like telling a start-up founder they aren't actually changing the world for the better : /
