I'm Number One! Does Narcissism Impair Ethical Judgment Even for the Highly Religious?

Can an assessment of individuals' narcissism help explain the quality of a respondent's ethical judgment? How is the relationship between religiosity and ethical judgment moderated by the effects of narcissism? With a sample of 385 undergraduate business majors, this study uses a taxonomic approach to examine the effects of intrinsic and extrinsic religiosity as well as orthodox Christian beliefs on ethical judgment. Three distinct clusters were identified: Skeptics, Nominals, and Devouts. Surprisingly, of the three clusters, Nominals and Devouts were the only groups impacted by narcissism, although Skeptics overall demonstrate the worst ethical judgment.
