TEORÍAS DE LA EVOLUCIÓN DEL COMPORTAMIENTO COOPERATIVO: UNA REVISIÓN CRÍTICA

In this paper we survey the theories of gratuitous cooperation, i.e., in favour of non-relatives and without repeated interaction. We also describe our work on the area, whose objective is to integrate the various theories of gratuitous cooperation into a self-contained framework. Our conclusions are as follows. First: altruistic punishment, conformism, and gratuitous cooperation coevolve, and group selection is a necessary for the coevolution to take place. Second: people do not cooperate by mistake, as most theories imply. On the contrary, people knowingly sacrifice themselves for others. Third: in cooperative dilemmas conformism is an expression of preference, not a learning rule. Fourth: group mutations are necessary to sustain cooperation in the long-run.
