T_4_15 — The Psychology of Cooperation and Trust: Game Theory, Reciprocity, and Institutions

Cooperation — acting in ways that benefit others at a cost to oneself — is both theoretically puzzling (why would natural selection favor organisms that sacrifice fitness for others?) and practically essential (every hum
