Although dishonesty is often a social phenomenon, it is primarily studied in individual settings. However, people frequently collaborate and engage in mutual dishonest acts. We report the first meta-analysis on collaborative dishonesty, analyzing 87,771 decisions (21 behavioral tasks; k = 123; n_participants = 10,923). We provide an overview of all tasks used to measure collaborative dishonesty, and inform theory by conducting moderation analyses. Results reveal that collaborative dishonesty is higher (a) when financial incentives are high, (b) in lab than field studies, (c) when third parties experience no negative consequences, (d) in the absence of experimental deception, and (e) when groups consist of more males and (f) younger individuals. Further, in repeated interactions, group members’ behavior is correlated—participants lie more when their partners lie—and lying increases as the task progresses. These findings are in line with the justified ethicality theoretical perspective, suggesting prosocial concerns increase collaborative dishonesty, whereas honest-image concerns attenuate it. We discuss how findings inform theory, setting an agenda for future research on the collaborative roots of dishonesty.

合作不诚实：荟萃分析评论。

尽管不诚实通常是一种社会现象，但它主要在个人环境中进行研究。然而，人们经常合作并参与相互不诚实的行为。我们报告了第一个关于协作不诚实的元分析，分析了 87,771 个决策（21 个行为任务；k = 123；n 个_参与者= 10,923)。我们概述了用于衡量合作不诚实的所有任务，并通过进行适度分析来告知理论。结果表明，（a）当经济激励很高时，（b）在实验室中比在现场研究中，（c）当第三方没有受到负面影响时，（d）在没有实验性欺骗的情况下，（e）当群体由更多的男性和 (f) 年轻人组成时。此外，在重复的互动中，小组成员的行为是相关的——当他们的伙伴撒谎时，参与者撒谎的次数更多——并且随着任务的进行，撒谎的次数也会增加。这些发现与正当的伦理理论观点一致，表明亲社会关注会增加合作不诚实，而诚实形象关注会削弱它。我们讨论了研究结果如何为理论提供信息，
