Individuals that participate in exchanges with delayed rewards can be exploited if their partners don't reciprocate. In humans, friendships are built on trust, and trust enhances cooperation. New evidence suggests that close social bonds also enhance trust in chimpanzees.
如果个体与延迟奖励的伙伴进行交流时没有得到回报，那么他们可能会被利用。在人类中，友谊建立在信任的基础上，而信任则增强了合作。新的证据表明，紧密的社会关系也增强了黑猩猩之间的信任。
