Abstract
Ambivalent sexism theory recognizes that sexist attitudes maintain gender inequalities via sociocultural and close relationship processes. This review advances established work on sociocultural processes by showing how people’s need for relationship security is also central to the sources and functions of sexism. Men’s hostile sexism—overtly derogatory attitudes toward women—involves insecurities about women exploiting men’s relational dependence. Accordingly, men’s hostile sexism predicts relational aggression when their dependence on partners is risky. Men’s benevolent sexism—patronizing and protective attitudes toward women—offers men relationship security by idealizing traditional gender roles in romantic relationships. Benevolent sexism also appeals to women who seek the security of a devoted partner, but requires women to invest in their relationship at the expense of their independence. Our relationship science perspective reveals that romantic (in)security is critical to why people adopt sexist attitudes and why sexist attitudes create differential costs and benefits for women and men.
