(Talk in English)
In this talk, I will raise (and try to answer) two questions regarding human cooperation: Why we cooperate the way we do (and not differently)? And why other species do not cooperate as much? I will first present models showing that the possibility to choose our social partner(s) constrains the way we cooperate, forcing us to give others as much as they could have obtained with a different partner. This simple principle explains some important properties of human cooperation —properties that human beings call fairness. I will then present further models, together with results from evolutionary robotics simulations, that explain why this form of cooperation, based on fair reciprocity, has not appeared more often in evolution, and that help make sense of the specific instances in which it occurs outside humans.
