A Nash equilibrium is a set of strategies, one for each player, such that no player can improve their outcome by changing their strategy while the other players keep their strategies unchanged.

A prisoner's dilemma is a situation where two or more players have common interests, but each player is tempted to defect from the cooperative strategy in order to improve their own outcome, even though this leads to a worse outcome for all players.

A tragedy of the commons is a situation where two or more players have conflicting interests and each player's best strategy is to exploit the common resource, even though this leads to a worse outcome for all players.

A zero-sum game is a situation where two or more players have conflicting interests and the outcome of the game is determined by the sum of the players' payoffs, such that one player's gain is exactly offset by the other player's loss.

Game theory can be used in sociology to analyze social interactions in a variety of ways, including predicting the behavior of individuals in social groups, understanding the dynamics of social networks, and modeling the evolution of social norms.

Game theory can be used in anthropology to analyze cultural practices in a variety of ways, including understanding the origins of cultural practices, explaining the persistence of cultural practices, and predicting the evolution of cultural practices.

A social dilemma is a situation in which individuals have conflicting interests and the outcome of the game is determined by the sum of the players' payoffs, such that one player's gain is exactly offset by the other player's loss. The tragedy of the commons, the prisoner's dilemma, and the ultimatum game are all examples of social dilemmas.

A cultural norm is a shared belief or expectation about how people should behave in a particular situation. Shaking hands when you meet someone, saying "please" and "thank you", and wearing clothes in public are all examples of cultural norms.

Game theory can be used to model the evolution of cultural norms using a variety of methods, including replicator dynamics, diffusion models, and learning models.

The Boyd and Richerson model of cultural transmission, the Henrich and Boyd model of prestige-biased transmission, and the Durham model of conformist transmission are all examples of game theoretic models of cultural evolution.

Game theory can be used to analyze the dynamics of social networks using a variety of methods, including network formation models, network diffusion models, and network learning models.

The Jackson and Wolinsky model of network formation is an example of a game theoretic model of network formation.

The DeGroot model of social influence, the Friedkin and Johnsen model of social influence, and the Granovetter model of the strength of weak ties are all examples of game theoretic models of network diffusion.

The Axelrod model of cultural diffusion, the Ellison model of social learning, and the Glaeser and Scheinkman model of social learning are all examples of game theoretic models of network learning.

Game theory can be used to predict the behavior of individuals in social groups using a variety of methods, including rational choice models, bounded rationality models, and social identity models.
