Abstract
This research investigates the ways in which (un)shared religious group memberships contribute to individual helping responses through perceived similarity in the context of a refugee emergency. Across three studies (N = 762), we examined religious sub-groups of British people’s helping responses to religious subgroups of Syrian refugees, in quasi-experimental and experimental designs. Overall findings suggest that sharing a religious group membership with refugee targets increases perceived similarity, political support, and helping intention, but not charitable donation—regardless of shared group membership being subtle or salient. However, when refugee targets’ religious identity is that of a salient unshared group membership, not sharing a religious group membership reduces perceived similarity, political support, and helping intention, among those who are religious—with again charitable donation remaining unchanged. These results provide critical insights into developing more effective and unique strategies to promote and mobilize support for refugees among different groups of potential helpers.
