On average, men are more narcissistic than women, report researchers, who say the findings apply across multiple generations and regardless of age.
Forthcoming in the journal Psychological Bulletin, the study compiles 31 years of narcissism research, including over 475,000 participants.
“Narcissism is associated with various interpersonal dysfunctions, including an inability to maintain healthy long-term relationships, unethical behavior, and aggression,” says lead author Emily Grijalva, assistant professor of organization and human resources in the University at Buffalo School of Management.

“At the same time, narcissism is shown to boost self-esteem, emotional stability, and the tendency to emerge as a leader,” she says. “By examining gender differences in narcissism, we may be able to explain gender disparities in these important outcomes.”
The researchers examined more than 355 journal articles, dissertations, manuscripts, and technical manuals, and studied gender differences in the three aspects of narcissism: leadership/authority, grandiose/exhibitionism, and entitlement.
They found the widest gap in entitlement, suggesting that men are more likely than women to exploit others and feel entitled to certain privileges.
The second largest difference was in leadership/authority. “Compared with women, men exhibit more assertiveness and desire for power,” Grijalva says. “But there was no difference in the exhibitionism aspect, meaning both genders are equally likely to display vanity or self-absorption.”
Narcissism and Stereotypes
In addition, the study looked at data from college students between 1990 and 2013, and found no evidence that either gender has become more narcissistic over time.

Research has shown that personality differences, like narcissism, can arise from gender stereotypes and expectations that have been ingrained over time. The authors speculate that the persistent lack of women in senior leadership roles may partially stem from the disparity between stereotypes of femininity and leadership.
“In particular, women often receive harsh criticism for being aggressive or authoritative, which creates pressure for women, more so than for men, to suppress displays of narcissistic behavior.”
Future research could further investigate the social, cultural, or biological factors that contribute to these gender differences.
