Well, Freud was the first to say (or at least the first to popularise) ideas that - in retrospect - should be obvious, like that human behaviour is motivated by unconscious drives, or that past trauma influences your current behaviour. However most of his theories about how the unconscious works were basically unfalsifiable and based on nothing more that his own interpretation of what he’s noticed about his own patients (though to be fair, I think that’s mostly the case for most of psychology). I think a lot of the early psychology of Freud, Adler, and Jung is quite enmeshed with the philosophy of Nietzsche (who said some truly wild about human nature without providing a single source) and remains more popular than it should be for that reason.
Wasn’t Freud massively debunked?
