Social Dominance Orientation Scale

What it measures

Measures the general desire for hierarchical and unequal relationships between social groups — the belief that some groups are naturally superior to others and should dominate subordinate groups. The SDO7 revision distinguishes SDO-Dominance (active preference for group-based dominance and aggression) from SDO-Egalitarianism (opposition to equality). High SDO predicts prejudice toward outgroups, support for intergroup discrimination, and opposition to policies that reduce group inequality (affirmative action, welfare programmes). In consumer and marketing research, SDO moderates responses to diversity in advertising, inclusive marketing campaigns, LGBTQ+ brand positioning, and cause-related marketing. A critical variable for research on attitudes toward inclusive advertising.
