We design a novel experiment to examine the role of inertia in choosing partners, that is, a preference for staying with one’s original partner when offered an opportunity to switch. Our data show that the majority of participants who are offered the choice to play a new game with their original partner or a new partner will choose the original partner, even when they deceived their original partner in order to gain selfish profits. The results may suggest the importance of considering inertia in partner selections, in addition to economic incentives.

伙伴关系中的惯性。

我们设计了一个新颖的实验来检验惯性在选择合作伙伴中的作用，也就是说，当有机会转换时，他偏爱与原来的合作伙伴呆在一起。我们的数据显示，大多数被允许选择与原始合作伙伴或新合作伙伴玩新游戏的参与者会选择原始合作伙伴，即使他们欺骗了原始合作伙伴以获取自私利润。结果可能表明除了经济激励外，在选择合作伙伴时考虑惯性的重要性。
