Document Summary
Prosocial behaviour: any act performed with the goal of benefiting another person. You can act in a prosocial way of out self-interest. Altruism: the desire to help others, even if it involves a cost to the helper. People help others because of three factors that have become ingrained in our genes: kind selection, the norm of reciprocity, and the ability to learn and follow social norms. Kin selection: the idea that behaviour that helps a genetic relative is favoured by natural selection. More likely to help genetic relatives than nonrelatives in life-and-death situations but not when the situation was non-life threatening. The critical variable is the degree of closeness: participants were most likely to help the family members to whom they had the closest emotional ties, rather than those to whom they were most closely related. Norm of reciprocity: the expectation that helping others will increase the likelihood that they will help us in the future.
