Story summary
- Two studies at the University of Southampton found that pronounced grandiose narcissism is linked to blunted error-related negativity (ERN) responses, indicating reduced sensitivity to mistakes.
- The blunted ERN persisted even with clear external feedback.
- The studies included 144 and 50 undergraduate participants, respectively, suggesting narcissism may hinder self-corrective learning and reinforce positive self-views.
- The research was published in the Journal of Personality and primarily involved white, British students.
