Game Theory

Roles: player, strategy, payoff, equilibrium, defection, cooperation, round, information-set

The mathematical study of strategic interaction between rational agents. Encompasses zero-sum and non-zero-sum games, iterated and one-shot encounters, and the tension between individual rationality and collective welfare. As a source domain, it provides the vocabulary of Nash equilibria, dominant strategies, and payoff matrices that has colonized economics, political science, evolutionary biology, and AI alignment discourse.
