How does gender equality relate to men's and women's value priorities? It is hypothesized that, for both sexes, the importance of benevolence, universalism, stimulation, hedonism, and self-direction values increases with greater gender equality, whereas the importance of power, achievement, security, and tradition values decreases. Of particular relevance to the present study, increased gender equality should also permit both sexes to pursue more freely the values they inherently care about more. Drawing on evolutionary and role theories, the authors postulate that women inherently value benevolence and universalism more than men do, whereas men inherently value power, achievement, and stimulation more than women do. Thus, as gender equality increases, sex differences in these values should increase, whereas sex differences in other values should not be affected by increases in gender equality. Studies of 25 representative national samples and of students from 68 countries confirmed the hypotheses except for tradition values. Implications for cross-cultural research on sex differences in values and traits are discussed. (PsycINFO Database Record (c) 2009 APA, all rights reserved).
