This sort of thing is what made quant/math psych so intriguing to me as an undergrad. It was easy to become disillusioned with mainstream psych curriculum, when—by and large—classes functioned more to describe "popular effects" rather than to understand psychological capacities. https://twitter.com/psipear/status/1201818501998170113

One of my favorite undergrad classes ended up being "human motor control and learning". Not because we talked about interesting/surprising effects, but because we learned about general laws underlying learning and movement. Compared to rote memorization, it was enlightening!
