One study of high school students found very high rates of “rape supportive beliefs”, that is, acceptance of rape myths and violence against women. The boys who were the most frequent consumers of pornography and/or who reported learning a lot from it, were more accepting of rape supportive beliefs than their peers who were less frequent consumers and/or who said they had not learned as much from it.
A full 25% of girls and 57% of boys indicated belief that in one or more situations, it was at least “maybe okay” for a boy to hold a girl down and force her to have intercourse. Further, only 21% of the boys and 57% of the girls believed that forced intercourse was “definitely not okay” in any of the situations. Forced intercourse was most accepted was that in which the girl had sexually excited her date. In this case 43% of the boys and 16% of the girls stated that if was at least “maybe okay” for the boy to force intercourse. - Kristin Maxwell and James Check, “Adolescents’ rape myth attitudes and acceptance of forced sexual intercourse.” Paper presented at the Canadian Psychological Association Meetings, Quebec, June 1992.
