“…For example, Guala and Filippin () found that people altruistically allocated more money towards an ingroup member victim and were more likely to punish an outgroup perpetrator (Guala & Filippin, ). This finding is further supported by previous research which has observed that ingroup members who violate social norms will be less harshly punished than outgroup members due to ingroup favouritism (DeSmet et al, ; Guala & Filippin, ; Guo, Xu, Wu, & Hu, ; McAuliffe & Dunham, ; Wang et al, ). What remains less known, however, is whether the identity of the perpetrator (as an ingroup or outgroup member) moderates or is moderated by other factors (e.g., empathy, perceived injustice) in the dictator game and influences altruistic behaviour choices.…”
