The prisoner’s dilemma (PD) is a two-player game where there is a conflict between individual and group interests. Overall, both players do better if they both cooperate, yet each individual player does better if they defect. However, if both players defect then they do worse than if they both cooperate, hence the dilemma. This deceptively simple game has been used extensively to explore the conditions under which cooperation can evolve.
