Schadenfreude is a joyful emotional response to the misfortune of others. Individuals' schadenfreude over the misfortunes of ingroup and outgroup members may vary depending on how groups interact. Accordingly, this study examines the effects of different social interaction patterns and group identity on schadenfreude and their mechanisms. The study participants were Chinese college students. Study 1 (n = 83) investigated whether there are differences in individuals' schadenfreude towards ingroup and outgroup members under two different patterns of social interaction: cooperation and competition. On the basis of this study, Study 2 (n = 73) focused on the mechanisms underlying the influence of individuals' Schadenfreude on ingroup and outgroup members in competitive situations, and the mediating role of disgust. It was found that there was an interaction between group identity and social interaction patterns, with people showing more schadenfreude over the misfortunes of outgroup members than ingroup members, and competitive situations increasing disgust and schadenfreude over outgroup members. However, no differences were found in individuals' schadenfreude towards ingroup and outgroup members in cooperative situations. This is instructive in terms of real-life intergroup relations as well as patterns of social interaction. This proves that cooperation and group contact is a way to reduce schadenfreude.
