Past research has already considered how social values may affect inter-group decision making (Van Avermaet & McClintock, 1988; Rabbie, Schotm & Visser, 1989; Platow, McClintock & Liebrand, 1990). Within the context of the minimal group paradigm it has been observed that competitive and selfish people tend to maximize ingroup gain over fairness in their inter-group allocations, while prosocial oriented people are expected to prefer fair gains over intergroup biased allocations (Platow et al., 1990). However, basing on this literature, it is unclear whether people will maintain their preference over allocation of resources even after having discovered the presence of a cheater inside the group. Furthermore, the reaction to rule-breaking behaviors may also affect people¿s attitude over egalitarianism and belief in a just world (i.e., people who believes in a just world would reserve harsher treatment to the cheater). Thus, we are also interested in investigating whether reactions to ingroup (vs. outgroup) cheater are affected not only by preexisting social values, but also whether the relationship between deviant derogation and pro-self allocations is moderated by people¿s attitude over egalitarianism and belief in a just world.
