The Importance of Self-Interest in Psychology

There's this huge emphasis on self-interest, which I do think is rational, like, to the belief, but just annoys me. There are all these psychologists who I just like, hey, John Watson and Bea Skinner, an example. And it's that general issue where I'm getting very frustrated that in a lot of my university courses, they only teach about white male researchers. It feels like there are so many more creative ideas that have come out in the last like, hundred years or fifty years that are actually provided better explanation than these experiments.
