Religious individuals assert superior, but false, knowledge on domains highly relevant to religiosity (e.g., international health charities, humanitarian aid organizations)

Do Religious People Self-Enhance? Constantine Sedikides, Jochen E Gebauer. Current Opinion in Psychology, August 10 2020. https://doi.org/10.1016/j.copsyc.2020.08.002

We ask if and when religious individuals self-enhance more than non-believers. First, religious individuals self-enhance on domains central to their self-concept. Specifically, they exhibit the Better-Than-Average Effect: They rate themselves as superior on attributes painting them as good Christians (e.g., traits like “loving” or “forgiving,” Biblical commandments) than on control attributes. Likewise, they exhibit the Overclaiming Effect: They assert superior, but false, knowledge on domains highly relevant to religiosity (e.g., international health charities, humanitarian aid organizations) than on control domains. Second, religious individuals self-enhance strongly in religious (than secular) cultures, which elevate religion to a social value. Finally, Christians may self-enhance in general, perhaps due to their conviction that they have a special relationship with God.
