I think you have some misconceptions about psychology in general. E.G. you name Stanford Prison, and then explain that it has not been replicated. The act of trying (and failing) to replicate those results is psychological research, and then you reference this research as argument against psychology. Also, you seem to suggest like psychology is deterministic (A happens to someone, so they react in way B), while it is a probabilistic science (if A happens to someone, the chance that they will react in way B increases by X% to Y% with a probability of 95%).

One comment on your example: The prisoner’s dilemma (the way I know it) is not a psychological, but a game theoretical concept and is usually applied with the assumption of rational actors a one-shot interaction, which means that it doesn’t apply to your situation with your friend.

In general, it seems that your disdain for psychology stems from laypersons’ broad and biased understanding of psychological concepts.

Disclaimer: I am not a psychologist.

Do you work at the Carnival?

I lived in New York! (Not really though, just quoting Britta from Community - in the first comment, too)
