Although religious identification often correlates positively with traditional gender role attitudes and ambivalent sexism (Mikołajczak & Pietrzak, Sex Roles, 70(9–10), 387–399, 2014), other work shows it has countervailing associations with related conservative views (Lockhart et al., Religion, Brain & Behavior, 10(4), 379–392, 2020). One reason these opposing effects emerge is that insecure (or narcissistic) and secure forms of religious identification may have differing impacts on ambivalent sexism. To test this possibility, we analysed data from a nationwide random sample of adults who identified as religious (N = 1116). Whilst religious identification alone was unassociated with hostile and benevolent sexism, religious narcissism correlated positively with both forms of sexism. After including both predictors in a regression, religious identification correlated negatively with both forms of sexism and religious narcissism became a stronger positive correlate of sexism. These findings demonstrate that secure and insecure forms of religious identification suppress the respective positive and negative associations religious identification and religious narcissism have with sexism.
