"In 2012, a series of studies compared men in more "modern" marriages (whose wives worked outside the home full-time) to men in more "traditional" marriages (whose wives worked at home). The researchers wanted to determine if a man's home arrangement affected his professional behavior. It did. Compared to men in modern marriages, men in more traditional marriages viewed the presence of women in the workforce less favorably. They also denied promotions to qualified female employees more often and were more likely to think that companies with a higher percentage of female employees ran less smoothly. The researchers speculated that men in traditional marriages are not overtly hostile toward women but instead are "benevolent sexists" ---holding positive yet outdated views about women (another term I have heard is "nice guy misogynists")."
