经济决策取决于我们的社会环境。人类对亲密关系中的不平等往往会做出不同的反应，但我们对其他物种中这种差异的可能性知之甚少。我们研究了几组黑猩猩（Pan troglodytes）对不平等的反应，其范式类似于之前在卷尾猴（Cebus apella）中使用的范式。我们证明，像卷尾猴一样，黑猩猩对奖励不公平的反应是基于伙伴收到奖励，而不是仅仅基于奖励的存在。然而，我们还发现测试群体之间存在很大差异，这表明黑猩猩和人类一样，对不平等的反应也各不相同，我们推测这可能是由群体规模、群体的社会亲密程度（反映在群体在一起的时间长度）和特定群体的传统等变量引起的。
Economic decision-making depends on our social environment. Humans tend to respond differently to inequity in close relationships, yet we know little about the potential for such variation in other species. We examine responses to inequity in several groups of chimpanzees (Pan troglodytes) in a paradigm similar to that used previously in capuchin monkeys (Cebus apella). We demonstrate that, like capuchin monkeys, chimpanzees show a response to inequity of rewards that is based upon the partner receiving the reward rather than the presence of the reward alone. However, we also found a great amount of variation between groups tested, indicating that chimpanzees, like people, respond to inequity in a variable manner, which we speculate could be caused by such variables as group size, the social closeness of the group (as reflected in length of time that the group has been together) and group-specific traditions.
