This study explores the influence of education and religiosity on sexist attitudes towards women and rape myth acceptance in two samples totaling 399 participants from the United States and Italy. Both samples completed a demographic questionnaire that assessed age, area of residence, and racial and gender identification. Three questions about religiosity and three about education were included, as well as the Attitudes Towards Women Survey and the Acceptance of Modern Myths about Sexual Aggression. In the Italian pool, 44 held at least a bachelor’s degree, 108 had completed some college, and 29 completed high school at most, while the United States pool consisted of 83, 123, and 12, respectively. Average self-reported levels of religiousness were M = 3.87 (SD = 3.05) in Italy and M = 5.10 (SD = 2.76) in the United States. In both samples, religiosity was a strong predictor of both sexism and rape myth acceptance, while education was only related to rape myth acceptance and with less strength than religiosity. Moreover, country of residence was an important influence for sexist beliefs along with both religiosity and education; however, for rape myth acceptance, country did not have a significant impact.
