The aim of this article is to present the studies that illustrate collective guilt- a common phenomenon observed in the context of intergroup relations as a consequence of harming another group and stems from sharing group membership with the harm-doers. First of all, collective guilt is defined. In this description some psychological processes used as alternatives for collective guilt are mentioned and differences of collective guilt from personel guilt and collective shame are presented. Then, whether collective guilt can be experienced on the world stage is discussed and four social psychological factors that are asserted by researchers to generate collective guilt are elaborated. These factors are self categorization as a member of a group that has harmed another group, accepting one’s group to be responsible for the harm done to another group, perceiving the damaging behaviours done by ingroup as illegitimate and the cost of making reperations in terms of ingroup. Findings related to collective guilt experienced depending on mentioned four main factors and consequences of feeling collective guilt are shared. Finally, a common conclusion and future directions are presented.
