The evolutionary rationality of social learning

We have analyzed the long-term success of various social learning heuristics. Specifically, we have examined their ability to persist and to replace other heuristics, and we have done this in two broadly different kinds of environments: environments in which the optimal behavior varies across space, or through time. Because each social learning heuristic also shapes its environment as individuals use it, our analysis has been at the same time ecological, game-theoretic, and evolutionary: The performance of each social learning heuristic depends on assumptions about the environment and population structure in which it is used. The use of a particular social learning heuristic will affect the success of this and other social learning heuristics over time. Therefore, our analysis is directed at the long-term survival and reproduction of each social learning heuristic.
