He loves her, he loves her not.

A new study led by Joshua Hart, assistant professor of psychology, suggests that men's insecurities about relationships and conflicted views of women as romantic partners and rivals could lead some to adopt sexist attitudes about women.

The study was recently published in Personality and Social Psychology Bulletin, a peer-reviewed journal.

Hart and his co-authors, Jacqueline Hung '11, a former student of Hart's, and psychology professors Peter Glick of Lawrence University and Rachel Dinero of Cazenovia College, surveyed more than 400 heterosexual men to gauge their responses to questions about their attachment style, hostile and benevolent sexism, and views on romance.
