Mistrust is a common cause of conflict between individuals belonging to different identity groups. When can such mistrust be overcome? We present a theoretical model of trust-building across social identity groups to address this question. Trust between groups increases when individuals in one group are willing to take a chance on engaging with members of the other group, their engagement is positively reciprocated, and they are able to credibly communicate the experience to their fellow group members, thereby increasing their belief that members of the other group are trustworthy. This process is made easier if the individuals are not too hostile to the out-group, are flexible enough to change their beliefs in response to new information, and are sufficiently attached to their own group to be honest about their experiences with out-group members.

不信任是属于不同身份群体的个人之间发生冲突的常见原因。什么时候可以克服这种不信任？我们提出了一个跨社会身份群体建立信任的理论模型来解决这个问题。当一个群体中的个人愿意冒险与另一个群体的成员互动时，群体之间的信任就会增加，他们的参与会得到积极的回报，并且他们能够可靠地将经验传达给其他群体成员，从而增加他们的信念：另一组的成员是值得信赖的。如果个人对外群体不太敌视，足够灵活以改变他们的信念以响应新信息，并且对自己的群体有足够的依恋以诚实地讲述他们与外群体成员的经历，这个过程就会变得更容易.
