In this article, we investigate how being socially excluded (vs. included) affects people's distributive fairness judgements and their willingness to cooperate with others in subsequent interactions. For this purpose, we conducted three experiments in which we assessed individual differences in having experienced being socially excluded (Experiment 1, N = 164), and manipulated social exclusion (Experiment 2, N = 120; Experiment 3, N = 492). We studied how this impacted fairness judgements of three different outcome distributions (disadvantageous inequality, advantageous inequality, and equality) both within‐participants (Experiments 1 and 2) and between‐participants (Experiment 3). To assess behavioural consequences, we then also assessed participants' cooperation in a social dilemma game. Across the three experiments, we consistently found that social exclusion impacted fairness judgements. Compared to inclusion, excluded participants judged disadvantageous inequality as more unfair and advantageous inequality as less unfair. Moreover, compared to socially included participants, socially excluded participants were more willing to cooperate after experiencing advantageous rather than disadvantageous inequality, and feelings of acceptance served as a mediator in these associations.

社会排斥对分配公平判断和合作行为的影响


在本文中，我们研究了被社会排斥（与被包容）如何影响人们的分配公平判断以及他们在后续互动中与他人合作的意愿。为此，我们进行了三个实验，其中我们评估了经历被社会排斥（实验 1，N = 164）和操纵社会排斥（实验 2，N = 120;实验 3，n = 492）。我们研究了这如何影响参与者内部（实验 1 和 2）和参与者之间（实验 3）的三种不同结果分布（不利不平等、有利不平等和平等）的公平性判断。为了评估行为后果，我们还评估了参与者在社交困境游戏中的合作情况。在这三个实验中，我们一致发现社会排斥影响了公平性判断。与纳入相比，被排除在外的参与者认为不利的不平等更不公平，而有利的不平等认为不公平程度较低。此外，与社会包容的参与者相比，被社会排斥的参与者在经历有利而不是不利的不平等后更愿意合作，而被接受的感觉在这些关联中起到了中介作用。
