It's obvious why these findings are troubling for women, and not just because women don't want to worry that their partners are secretly begrudging them professional successes, poker winnings, and accomplishments in pub trivia. The results also might speak to the roots of some domestic abuse, as men who have the greatest need to "win" the relationship could be more motivated to undermine and control their partners. (The study isn't suggesting this—I am.) But these findings should also be troubling to men. Feeling insecure and competitive with your partner is no way to live. The researchers suggest that these kinds of feelings might be mediated by relearning how to think about gender roles, i.e. becoming more feminist. So add one more study to a growing pile that shows that feminism, despite conservative claims to the contrary, is actually good for couples and for harmony between the sexes.
