Investigating motivations underlying collective narcissism and in-group identification
Abstract
We draw on self-determination theory and research on religious orientations to investigate motivations associated with collective narcissism—a belief in in-group greatness that is underappreciated by others—versus secure in-group identity, an unpretentious positive regard for the in-group. Four surveys examined these associations focusing on different social identities: personally important groups (Study 1, N = 212), nationalities (Study 2, N = 196), and religious groups (Study 3, N = 1,690; Study 4, N = 399). In Studies 1, 2, and 4, self-determined motivations were associated with secure in-group identity, whereas non-self-determined motivations were related to collective narcissism. In Studies 3 and 4, intrinsic religiosity was related to collective narcissism and secure in-group identity, while extrinsic personal religiosity was associated with collective narcissism only. Results indicate that collective narcissism is motivated by seeking external and internal rewards.
