| Outline of Final Research Achievements |
We focused on friendships, which is the most fundamental of human relationships, and investigated the norms of non-reciprocal altruism in close friendships, in order to identify the mechanisms of social norm formation. We assumed that the mutual irreplaceability in friendship was a key concept predicting the formation of beliefs about non-reciprocal altruism. Helping friends with irreplaceable abilities or talents is an adaptive behavior, because such, mutual irreplaceable friends have a crisis management function of avoiding the risk of illnesses or injuries, by helping each other. Several studies have indicated that the formation of mutual irreplaceability increases the shared belief in non-reciprocal altruism. Also, it has been indicated that people use indirect requests for social support seeking, in order to assess whether their friends are true friends or not.
