The concept describes a social expectation where individuals respond to a positive action with another positive action. It is a fundamental principle in social psychology, suggesting that people feel obligated to return favors, gifts, or services received. For example, if a person receives a birthday gift, they may feel compelled to give a gift to that person on their birthday.
This inclination is critical for maintaining social cohesion and cooperation within groups. It fosters trust and mutual support, contributing to the stability of social relationships. Historically, this behavior likely evolved to facilitate collaboration and resource sharing within communities, increasing chances of survival and prosperity for its members.
