The relationship between social dominance orientation and gender: The mediating role of social values

Invariance hypothesis posits that, across cultures and contexts, men are higher in SDO than women. Social Dominance Theory (SDT) suggests that this difference is biologically determined and resulting from the differences in reproductive strategies between sexes. In this study we tested the hypothesis that values can explain gender-SDO differences. SDT suggests that SDO mediates gender differences in values. The contrasting hypothesis suggests that gender-SDO differences are mediated by values. Using SEM with a sample of Italian University students (N= 162, 80 men), the results provided strong support for the hypothesis of a mediation effect of values. Indeed, when controlling for values, gender difference in SDO disappear. Very similar findings were obtained for both GBD and OEQ. Results are discussed.
