Gender Differences in Social Dominance Orientation: Gender Invariance May Be Situation Invariance

Most studies of gender differences in social dominance orientation (SDO) have investigated settings more or less hierarchy-enhancing. The aim of this study was to explore gender differences in SDO (1) within social structures varying in equality-enhancement, i.e., communities differing in political equality between men and women, and (2) settings where equality was maximized and held constant, i.e., democratic, voluntary associations, but varying in gender composition, using survey data from a random sample of 831 Swedish adults (median age = 47 years). There was a significant interaction effect between gender and membership in voluntary associations dominated by women, with men and women displaying equally low levels of SDO. In all other instances the main effect of gender remained statistically significant.
