Depends on the school and professor I guess. My intro to psych class made it clear how much older paradigms are, basically, just flights of fancy, however there is a foundation of moving towards a system of discovery and diagnoses that was important, instead of literally super natural explanations. With new stuff they went over how difficult it is to create solid proofs and the reasons why. They also would do what they could to make sure we understood why they came to the conclusions they did and the short comings of those reasons and practices.
