Collective rationality

from Wikipedia, the free encyclopedia

Collective rationality is a term from game theory . The solution to a game is collectively rational if it maximizes the sum of the individual benefits of all available players. A collectively rational solution is also Pareto-optimal , i. That is, no player can be better off without another being worse off. The opposite of collective rationality is individual rationality .

Collective and individual rationality are not mutually exclusive, but neither are they mutually dependent. The difference between individual and collective rationality becomes particularly clear in the prisoner's dilemma .
