      abstract = {Intelligence affects the social outcomes of groups. A  systematic study of the link is provided in an experiment  where two groups of subjects with different levels of  intelligence, but otherwise similar, play a repeated  prisoner’s dilemma. Initial cooperation rates are similar,  but increase in the groups with higher intelligence to  reach almost full cooperation, while they decline in the  groups with lower intelligence. Cooperation of higher  intelligence subjects is payoff sensitive and not  automatic: in a treatment with lower continuation  probability there is no difference between different  intelligence groups.},
