Khái niệm cốt lõi
Reciprocity in humans is based on the idea of mutual benefit, but the evolutionary path to this behavior is complex and may require group cooperation.
Tóm tắt
Reciprocity in humans is a well-understood concept where individuals help each other with the expectation of receiving help in return. Efferson et al. challenge this notion by suggesting that for reciprocity to evolve, natural selection must also favor groups that cooperate. This highlights the complexity of the evolutionary path to reciprocal cooperation and questions its feasibility without group-level selection.
Thống kê
A rich body of theoretical work has confirmed the idea that reciprocal cooperation is advantageous as long as there is a high probability of interacting with the same person again.
Individuals preferentially help those who have previously helped them.
