Agents with Moral Sentiments in an Iterated Prisoner’s Dilemma Exercise

Contents

We present the results of a simulation of the Iterated Prisoner’s Dilemma where some agents behave rationally and others have moral sentiments towards those from the same social group. They suggest that in societies where agents can possess such characteristics, to behave rationally, in the usual sense in Game Theory, is not the best attitude for good performance in the long run, both individually and for the group.
