概要 Humans form complex societies in which we routinely engage in social decision-making regarding the allocation of resources among ourselves and others. One dimension that characterizes social decision-making in particular is whether to prioritize self-interest or respect for others-proself or prosocial. What causes this individual difference in social value orientation? We propose and experimentally test the hypothesis that differences in social preferences stem from which learning system is dominant in an individual. The results showed that proselfs depended more on model-based learning, whereas prosocials depended more on model-free learning. These findings support the learning hypothesis on what makes differences in social preferences and have implications for understanding the mechanisms of prosocial behavior.
