Social norms and the indirect evolution of conditional cooperation

Open Access
Article

Abstract

We develop a model of social norms and cooperation in large societies. Within this framework we use an indirect evolutionary approach to study the endogenous formation of preferences and the co-evolution of norm compliance. The multiplicity of equilibria, which emerges in the presence of social norms, is linked to the evolutionary analysis: individuals face situations where many others cooperate as well as situations where a majority free-rides. The evolutionary adaptation to such heterogenous environments favors conditional cooperators, who condition their pro-social behavior on the others’ cooperation. As conditional cooperators react flexibly to their social environment, they dominate free-riders as well as unconditional cooperators.
