由此衍生出一个间接互惠的循环网络，将3人或6人的群体组织成社会互动圈，其中第一个个体可以帮助第二个个体，第二个个体可以帮助第三个个体，以此类推，直到最后一个个体，后者反过来又可以帮助第一个个体。相互合作是通过假设一个人传递给下一个人的东西乘以3倍来触发的。参与者在搭档或陌生人的情况下反复游戏，先同时做出决定，然后依次做出决定。我们发现，纯粹的间接互惠使相互合作成为可能，尽管战略考虑和群体规模也很重要。(c) 2005 Elsevier B.V.版权所有
A cyclical network of indirect reciprocity is derived organizing 3- or 6-person groups into rings of social interaction where the first individual may help the second, the second the third, and so on until the last, who in turn may help the first. Mutual cooperation is triggered by assuming that what one person passes on to the next is multiplied by a factor of 3. Participants play repeatedly either in a partners or in a strangers condition and take their decisions first simultaneously and then sequentially. We find that pure indirect reciprocity enables mutual cooperation, although strategic considerations and group size are important too. (c) 2005 Elsevier B.V. All rights reserved.
