>>81624712 (OP)He was right about a lot of things and misguided on others but perhaps his biggest discovery was how much the pleasure and pain principle defines what we do and how early experiences shape and predict future pathologist.
He gets a lot of flak in modern times but its important to remember that he was basically on the ground floor with a lot of this.
Watson, Pavlov, and Skinner are also some big names that dont get enough recognition largely because behaviorism as a school of thought in psychology still causes a lot of booty hurt by people who insist on having metaphysics in psychology.
I would go so far as to say that the main reason people like Freud and to a lesser extent Jung are more popular is because people WANT there tk be metaphysics involved. They want psychology to be a quasi-religion instead of a hard science.
But as technology advances with our understanding of neurology it is behaviorism that is being vindicated in the end. Almost all modern therapy is based on behaviorism and psychoanalysis is now a very small fringe practice.
