# Social Dominance Theory Social Dominance Theory (SDT) is a framework developed by [[Jim Sidanius]] and [[Felicia Pratto]] in the 1990s to explain why human societies reliably organize into group-based [[Dominance Hierarchies]]. The theory posits that all complex societies produce at least one dimension of group-based stratification — typically along lines of age, gender ([[Patriarchy]]), and an arbitrary-set distinction such as race, caste, or ethnicity. SDT asks not merely *whether* hierarchies exist but what psychological and institutional mechanisms maintain them across time. Unlike purely structural accounts, SDT integrates individual psychology (orientation toward dominance), cultural ideology (legitimizing myths), and institutional behavior (hierarchy-enhancing vs. hierarchy-attenuating organizations) into a single multilevel model. This makes it one of the most comprehensive theories in [[Political Psychology]] for explaining persistent group-based oppression — and for predicting who will support or resist it. ## Social Dominance Orientation The theory's key individual-difference variable is Social Dominance Orientation (SDO) — one's preference for inequality among social groups. High-SDO individuals endorse statements like "some groups are simply inferior" and resist egalitarian policies such as [[Affirmative Action]] or [[DEI]] initiatives. SDO reliably predicts support for [[Right-Wing Authoritarianism]], opposition to [[Immigration]] reform, endorsement of harsh policing (see [[War on Drugs]]), and comfort with [[White Supremacy]] as a structural reality. Whereas [[Bob Altemeyer]]'s RWA scale captures submission to authority, SDO captures the *desire to dominate* — and the two interact multiplicatively in predicting [[Moral Disengagement]] toward out-groups. ## The Dual-Process Model: SDO + RWA Altemeyer and Sidanius's dual-process model shows that SDO and RWA are relatively independent predictors that together account for most variance in generalized prejudice. RWA channels threat-sensitivity and conformity; SDO channels competitive dominance and [[Dark Triad]] traits (particularly [[Narcissism]] and [[Psychopathy]] at subclinical levels). People high in both are drawn to [[Fascism]]-adjacent movements — they want *both* authoritarian order *and* group supremacy. The [[Manosphere]], [[Red Pill]] communities, and [[Dark Enlightenment]] thinkers like [[Curtis Yarvin]] and [[Peter Thiel]] exemplify high-SDO ideology stripped of traditional RWA religiosity. ## Empirical Patterns SDO correlates negatively with empathy and agreeableness and positively with tough-mindedness and preference for competitive over cooperative social arrangements. It predicts opposition to the [[Civil Rights Movement]]'s legacy, hostility toward the [[Labor Movement]], and endorsement of [[Eugenics]]-adjacent arguments such as those in [[The Bell Curve]] and [[Race Realism]] discourse. Men consistently score higher than women on SDO — what Sidanius calls the "invariance hypothesis" — which helps explain gendered patterns in support for [[Patriarchy]] and resistance to feminist policy. SDO levels rise when people perceive [[Zero Sum Game]] resource competition, making economic downturns and [[Austerity]] politics reliable SDO amplifiers. Crucially, SDO is not merely attitudinal — it predicts *behavioral* discrimination in hiring, sentencing recommendations, and resource allocation in experimental settings. ## Legitimizing Myths SDT introduces the concept of hierarchy-legitimizing myths: consensual ideologies that justify why some groups deserve more resources than others. [[Meritocracy]] ("anyone can succeed if they work hard"), the [[Prosperity Gospel]] ("God rewards the deserving"), [[Trickle-Down Economics]], and [[Supply-Side Economics]] all function as hierarchy-enhancing myths. They activate [[Motivated Reasoning]] and [[Identity-Protective Cognition]] to insulate believers from contrary evidence like persistent [[Gender Wage Gap]] data or [[Environmental Racism]] patterns. Hierarchy-attenuating myths — socialism, liberation theology — push in the egalitarian direction but typically lack institutional amplification. ## Institutional Enforcement Hierarchies persist not through individual attitudes alone but through hierarchy-enhancing institutions. [[ALEC]] drafts legislation favoring corporate power; the [[Federalist Society]] shapes judicial appointments; the [[Koch Network]] and [[Dark Money]] infrastructure bankroll policy that widens the gap between dominant and subordinate groups. Media institutions like [[Fox News]] broadcast [[Propaganda]] that normalizes group-based inequality, while [[Voter Suppression]] prevents subordinate groups from exercising countervailing political power. The [[Heritage Foundation]] and [[Project 2025]] represent hierarchy-enhancement at the policy-blueprint level. SDT emphasizes that individuals self-select into hierarchy-enhancing vs. hierarchy-attenuating roles. High-SDO people gravitate toward policing, corporate law, finance, and politics; lower-SDO people toward social work, public defense, and activism. This sorting amplifies structural inequality beyond what any single actor intends — a [[Stanford Prison Experiment]]-style emergent dynamic at civilizational scale. ## Relationship to Other Frameworks SDT overlaps with but is distinct from [[Authoritarian Personality Theory]] (rooted in [[Theodor Adorno]]'s psychoanalytic model) and [[System Justification Theory]] (which emphasizes motivated acceptance of the status quo even by disadvantaged groups — see [[Status-Quo Bias]] and Just-World Hypothesis). [[Moral Foundations Theory]] from [[Jonathan Haidt]] captures the loyalty/authority/sanctity values that correlate with SDO. [[Henri Tajfel]]'s minimal-group research and [[Gordon Allport]]'s [[The Nature of Prejudice]] provide the social-identity scaffolding SDT builds upon. [[Ingroup Bias]] and [[Collective Narcissism]] are downstream psychological mechanisms. Where System Justification Theory asks "why do the oppressed accept the system?" SDT asks "who actively *builds* the system and why?" This makes SDT particularly useful for analyzing elite behavior — the architects of hierarchy, not just its victims. ## SDO and the Contemporary Right [[Movement Conservatism]], [[National Conservatism]], and [[Christian Nationalism]] each channel high-SDO dispositions into policy programs. The [[Southern Strategy]] and [[Lee Atwater]]'s coded racial appeals exploited SDO by offering hierarchy-legitimizing frames without explicit racial language. [[Donald Trump]]'s rhetoric activates SDO through [[Zero Sum Game]] framing, [[Great Replacement Theory]] narratives, [[White Grievance]] appeals, and attacks on [[Political Correctness]] and [[Woke]] culture. [[Charles Murray]]'s work on IQ and race gives [[Scientific Racism]] an academic veneer that high-SDO audiences treat as confirmation of natural hierarchy. [[Carl Schmitt]]'s friend/enemy distinction provides the philosophical architecture for dominance politics repackaged by modern [[Populism]]. Research consistently shows that SDO — more than economic anxiety, religiosity, or partisan identity — is the single strongest predictor of support for [[Immigration]] restriction, [[Cultural Marxism]] moral panics, and opposition to redistributive policy. ## Open Questions - How much of SDO is heritable vs. socialized, and at what developmental window is it most malleable? - Can hierarchy-attenuating myths achieve cultural dominance in an era of algorithmic media that rewards [[Confirmation Bias]] and Affect Heuristic engagement? - Does rising [[Oligarchy]] / [[Plutocracy]] feedback-loop with mass SDO levels — i.e., does visible inequality *raise* population-level SDO? - What is the relationship between SDO and [[Cognitive Dissonance]] when dominant-group members encounter undeniable evidence of systemic harm? - How does SDO interact with [[Collective Narcissism]] in fueling [[White Grievance]] narratives and [[Great Replacement Theory]] adoption? - Does the Dunning-Kruger Effect compound SDO — do high-SDO individuals overestimate the competence gap between dominant and subordinate groups? - As [[Populism]] blends left-economic and right-cultural appeals, does SDO predict which version captures a given voter? ## Connections SDT provides the psychological spine connecting [[Authoritarianism]] as a governance mode, [[Fascism]] as its endpoint, and [[Neoliberalism]] plus [[Austerity]] as its economic instrument. The theory helps explain why Scapegoat dynamics target subordinate groups during economic stress, why [[Military-Industrial Complex]] spending enjoys bipartisan support from high-SDO elites, and why [[False Consciousness]] (per [[Antonio Gramsci]]) is not merely ignorance but actively maintained through hierarchy-legitimizing institutions. The [[Republican Party]] coalition since the [[Southern Strategy]] has successfully bundled high-RWA evangelicals with high-SDO economic elites — a coalition held together by shared opposition to the [[Civil Rights Movement]]'s egalitarian legacy. [[White Nationalism]] represents the coalition's logical extreme: explicit hierarchy-enhancement stripped of legitimizing myth. Understanding SDO as a measurable trait — not a moral judgment — makes it one of [[Political Psychology]]'s most empirically productive constructs for diagnosing why equality-advancing policy generates such visceral backlash. ## See Also - [[Right-Wing Authoritarianism]] - [[System Justification Theory]] - [[Authoritarian Personality Theory]] - [[Stanford Prison Experiment]] - [[Dominance Hierarchies]] - [[White Nationalism]] - [[Social Conservatism]]
