Group-centrism in the absence of group norms: The role of need for closure in social projection

The need for closure (NFC) promotes group-centrism, referring to the pursuit of a shared reality in a group, commonly achieved through conformity to and introjection of group norms. The present study expands this perspective by examining how NFC motivates projection of one’s own norms on groups, as an alternative means to achieve epistemic security in the absence of clear group norms. In Study 1 (N?=?261), individual differences in NFC predicted social projection onto an incidental crowd, providing evidence for the generic effect of NFC on social projection. In line with the assertion that the epistemic value of a collectivity is a function of the degree to which the collectivity matters for the individual, Study 2 (N?=?239) and Study 3 (N?=?223) revealed that NFC effects on social projection were strengthened for in-groups and disappeared for out-groups. Furthermore, mediation analyses demonstrated that essentialist entitativity beliefs mediate the relationship between NFC and in-group projection.
