Multidisciplinary Approach to the problem of social order-Examination of the effects of cognitive constraints and structures of social networks

为什么有可能在互不相关的自利个体之间实现大规模的相互合作，这是本研究的核心问题。虽然前人的研究没有从理论上解决这一问题，但本研究为解决这一问题找到了一定的未来方向。我们发现，我们需要建立一个包含两个因素的理论框架。首先，实现相互合作的情况与其他个人之间存在相互依存的情况不是独立的：它们相互影响。第二，试图保持相互合作的制裁人员在其他情况下可能会得到好处，尽管他们在目前的情况下必须支付制裁的代价。

Why it is possible to achieve a large-scale mutual cooperation among unrelated self-interested individuals is the core question of the current study. Although this question has not been solved theoretically in previous studies, the current study found certain future directions in order to resolve the problem. We found that we need to build a theoretical framework that incorporates two factors. First, the situation to achieve mutual cooperation and the other situations where interdependency exists among individuals are not independent : they influence each other. Second, sanctioners who try to maintain mutual cooperation may receive benefits in other situations although they have to pay the cost of sanctioning in the current situation
