Two preregistered experiments investigated the role of perceived group superiority in third-party territory ownership attributions (i.e., regarding a group as the possessor of a land) in intergroup contexts. Experiment 1 (N = 288) tested the effect of different versus same-time arrival to a territory on territory ownership attributions. The first-arriver group to a territory was more likely to be perceived as physically powerful, morally strong, and the owner of the territory than a newcomer (in within-subject comparisons) and a sametime arrival group (in between-subject comparisons), whereas a newcomer group was more likely to be perceived as more threatening than first-arriver (in within-subject comparisons) and same-time arrival (in between-subject comparisons) groups. Path analysis partially confirmed the proposed serial mediation model with perceptions of relative power, relative threat, and relative social distance as serial mediators of the association between arriving first at a territory and relative ownership attribution. Experiment 2 (N = 279) tested whether perceived group superiority affects ownership attributions. Physically (high wealth) and morally (high righteousness) superior groups as well as morally inferior groups (low righteousness) were more likely to be perceived as the owner of the territory than the groups who were physically and morally equivalent with other groups in the environment (control group). Implications of the present work for immigration attitudes and intergroup conflicts are discussed.
Public Significance StatementDividing groups into first-comers and newcomers of a territory can lead to the perception that these groups are in competition. The increase in the perceived intergroup distance caused by the threat of power differences may increase the perception that first-arriver groups own the territory. Reducing the (perceived) differences between groups' strengths may reduce the exclusionary perception of ownership that fuels conflicts. In particular, the findings of this study suggest that increasing the perceived economic equality and the perceived moral equality between groups may decrease asymmetric territory ownership perceptions.
