Sex differences in attitudes and behavior are nowhere more evident than in politics. But they also exist at the level of the mass public. Survey data have shown that women, as compared to men, tend to be less politically efficacious, less politically interested, have less political information, and are less likely to participate in politics. The explanations usually advanced for this phenomenon are either preadult sex-role socialization, or situational and structural factors encountered in adulthood. Dominant in the literature has been the socialization model. As part of sex-role socialization, boys are encouraged to be “politically expressive,” while girls are discouraged. This orientation, it is argued, persists beyond adolescence. The situational model disregards early sex-role learning and attributes differences in gender related political behavior to the circumstances and life-experience of adulthood. Almost all previous empirical research has been designed to test the socialization model. Our purpose, in this paper, is to test for the effects of situational factors on sex-related political attitudes and behaviors.
