Men are more narcissistic than women, study says

CHICAGO (WLS) -- When it comes to who's more vain, a new study says men top women.

Researchers at the University of Buffalo analyzed three decades worth of studies, involving nearly 500,000 people.

They were looking for gender differences in narcissistic behavior, typically defined as excessive self-interest or acting very self-centered.

They found that men - regardless of age - consistently showed higher levels of the trait than women.

Scientists said the biggest difference was men felt more entitled to privileges than women did.
