According to a new research at the University at Buffalo School of Management, men are indeed more narcissistic than women as they have greater senses of entitlement, making them more likely to exploit others.

A large study in the US that analysed more than 475,000 people concluded that men are indeed more narcissistic than women as is said several times. The findings of this study were in line among multiple age groups and generations, according to the researchers. They authors pointed out that narcissism may also have some positive effects and not only negative impact.

"Narcissism is associated with various interpersonal dysfunctions, including an inability to maintain healthy long-term relationships, unethical behaviour and aggression. At the same time, narcissism is shown to boost self-esteem, emotional stability and the tendency to emerge as a leader,"Emily Grijalva, assistant professor of organisation and human resources, and the paper's lead author.

The researchers analysed more than 355 journal articles, dissertations, manuscripts and technical manuals, and studied gender differences in what was described as three aspects of narcissism: leadership/authority, grandiosity/exhibitionism and entitlement. The researchers analysed reactions to statements, "If I ruled the world, it would be a much better place," and "I know that I am good because everyone keeps telling me so."
