evolutionary psychology

You are biologically tuned to catch social cheaters.

People consistently fail abstract logic puzzles but solve identical problems easily when they involve detecting rule-breakers in a social context.

Evolutionary psychology suggests the human mind evolved specific modules for social exchange. We are poor at raw deductive logic but highly efficient at identifying people who take benefits without fulfilling their obligations.

Your brain prioritizes fairness over pure reason.
