We introduce the distinction betwee

We introduce the distinction between perceiving the group as Intra-Generational (IG; including only the present generation of group members) and Trans-Generational (TG; including all past, present, and future generations of the group). In four studies (N = 1,265) administered to Jewish Israeli, Palestinian Israeli, American, and Swedish samples, we demonstrate that a tendency to perceive the group as TG is related to willingness to endure ingroup suffering and that this relationship is mediated by the degree to which the interest of the group as a whole is given primacy over the interest of the group as a collection of group members (Primacy of Interest).
