Prosocial behavior

Prosocial behavior, or "voluntary behavior intended to benefit another", is a social behavior that "benefit[s] other people or society as a whole," "such as helping, sharing, donating, co-operating, and volunteering." Obeying the rules and conforming to socially accepted behaviors (such as stopping at a "Stop" sign or paying for groceries) are also regarded as prosocial behaviors. These actions may be motivated by empathy and by concern about the welfare and rights of others, as well as for egoistic or practical concerns, such as one's social status or reputation, hope for direct or indirect reciprocity, or adherence to one's perceived system of fairness. It may also be motivated by altruism, though the existence of pure altruism is somewhat disputed, and falls into philosophical rather than psychological realm of debate. Evidence suggests that prosociality is central to the well-being of social groups across a range of scales. Empathy is a strong motive in eliciting prosocial behavior, and has deep evolutionary roots.
