This research examined reactions towards female rape victims from a system justification perspective. Study 1 demonstrated that gender-related system justification motivation (Modern Sexism) predicted the propensity to blame a female rape victim among men, but not among women. Modern sexism predicted rape victim blaming among men even when statistically controlling for a general antipathy towards women, and the results were unaffected by social desirability concerns. Consistent with previous study on system justification theory, we demonstrated in Study 2 that system justification motivation can predict victim blaming also among women, provided that complementary stereotypes about women have been activated. By contrast, system justification motivation predicted men’s propensity to blame a rape victim irrespective of whether complementary stereotypes about women had been experimentally activated.
