Prisoner's Dilemma
Cooperate or defect against a rational stranger you'll never meet.

You each independently choose one of two actions: COOPERATE (stay silent) or DEFECT (testify against the other). The outcomes are: - Both cooperate: each serves 1 year - Both defect: each serves 5 years - One defects, one cooperates: the defector goes free, the cooperator serves 10 years The other person is a rational stranger making the same choice in isolation.
