Short Summary: In a study of 475 MBA program executives organized into 105 study groups, this paper finds that people perform better on individually graded, group-dependent tasks when their own trait narcissism is closer to their group's average narcissism level. The results challenge the assumption that narcissists uniformly harm their teams, suggesting instead that narcissists (and non-narcissists alike) thrive when surrounded by similarly-natured teammates due to shared working norms and culture fit.
