Do We Become More Prosocial as We Age, and if So, Why?

Older adults contribute—through charitable donations or volunteering—more to the common good than younger adults, an age difference that has profound society-level implications. Yet the reasons for this difference are not well understood. Evidence suggests that a purely altruistic concern for the common good is a major motivation for prosocial behavior and that this concern increases across adulthood. We argue that this finding, and prosocial behavior in general, is better understood using a value-based decision framework than through traditional dual-process accounts. Following the value-based decision approach, we derive specific hypotheses about life-span changes in motivation or resources as factors that explain why older adults show an increased concern for the well-being of other people.
