It is interesting how powerful the meme is which prevents discussion of psychology and psychiatry amongst the laity. Multiple threads started and died on the theme of being a layperson and not an expert, despite the fact that any science should be examinable on its premises, observations, models, and theories.
Meanwhile, the Dodo Bird theory [0] has yet to be disproven, and there are good reasons to suspect that humans are merely smart mammals, rather than special animals who have no peers throughout the rest of the kingdom, which means that psychology and psychiatry are only the tip of a much bigger comparative discipline which handles humanity as a special case rather than as the main system of study.
