Understanding Social Dominance Orientation: The Psychology Behind Social Hierarchy

Have you ever wondered why some societies seem inherently structured around power dynamics, with certain groups consistently holding more influence and resources than others? Or why some individuals readily accept, and even champion, these disparities, while others vehemently oppose them? The answers often lie within a fascinating psychological concept known as Social Dominance Orientation (SDO).

What is Social Dominance Orientation (SDO)?

Social Dominance Orientation (SDO) is a personality trait that measures an individual's support for social hierarchy and their desire for their own in-group to be superior to out-groups. It reflects a fundamental preference for group-based inequality and dominance over principles of equality and inclusion. Essentially, people high in SDO believe that society should be structured hierarchically, with some groups naturally at the top and others at the bottom.

This concept was first proposed by psychologists Jim Sidanius and Felicia Pratto as a core component of their broader Social Dominance Theory (SDT). SDT posits that human societies, particularly those producing an economic surplus, tend to organize themselves into group-based hierarchies. These hierarchies are often stratified by factors such as age, gender, and "arbitrary-set" distinctions like race, ethnicity, social class, or religious affiliation.

The Two Faces of SDO: Dominance and Anti-Egalitarianism

While SDO is often discussed as a single construct, research suggests it has two complementary sub-dimensions:

• SDO-Dominance (SDO-D): This dimension reflects an individual's desire for active oppression of subordinate groups. It's associated with more overt, aggressive forms of intergroup phenomena like old-fashioned racism and support for war.
• SDO-Anti-Egalitarianism (SDO-E): This refers to a preference for inequality or a strong opposition to policies and practices that aim to reduce inequality. It's often linked to more subtle legitimizing ideologies, conservatism, and opposition to redistributive social policies.

Both dimensions contribute to an individual's overall SDO, but they can manifest differently in attitudes and behaviors.

Characteristics of Individuals with High SDO

Individuals who score high on measures of Social Dominance Orientation tend to exhibit several distinct characteristics and beliefs:

• Preference for Hierarchy: They desire to maintain and often increase the differences in social status between various groups and individuals.
• "Dog-Eat-Dog" Mentality: They often strongly adhere to the belief that the world is a competitive place where only the strongest survive, and one must assert power to succeed.
• Seekers of Power: High-SDO individuals are typically more inclined towards positions of power and tend to be driven by a desire for control. They may gravitate towards "hierarchy-enhancing" jobs and institutions like law enforcement or the military.
• Less Empathy for Outgroups: They tend to show less empathy or concern for groups perceived as subordinate.
• Support for Inequality-Maintaining Policies: They are more likely to endorse policies that reinforce existing social hierarchies and oppose those that promote equality, such as affirmative action or social welfare programs. They may also support autocratic leadership styles.

Conversely, individuals with low SDO scores tend to be more egalitarian, believing that all groups should be treated equally and supporting policies that promote social justice and human rights. They often show positive biases towards outgroup members and are better at detecting inequalities applied to low-status groups.

Where Does SDO Come From? Origins and Influences

The development of an individual's SDO is influenced by a complex interplay of factors:

• Temperament and Personality: SDO is considered a relatively stable personality trait. Research indicates a genetic component, suggesting that a predisposition towards hierarchical thinking can be partly inherited. SDO has been negatively correlated with personality traits like agreeableness and openness to experience, and with empathic concern.
• Socialization: The environments in which individuals are raised and the social groups they belong to significantly shape their SDO. Exposure to competitive social environments or particular societal structures can influence an individual's embrace of hierarchical views.
• Group Status: Members of high-status groups generally tend to exhibit higher SDO than members of low-status groups, as maintaining hierarchy aligns with their group's interests. However, SDO can also be context-dependent; even members of low-status groups may support hierarchical systems if they perceive potential advantages or if the hierarchy is seen as unstable and susceptible to change that could benefit their group.

The Real-World Impact of Social Dominance Orientation

SDO is not just an abstract psychological concept; it has profound implications for how individuals interact with society and how social structures are maintained or challenged.

SDO and Prejudice & Discrimination

Perhaps the most direct and well-documented impact of high SDO is its strong link to various forms of prejudice and discrimination. SDO is a robust predictor of:

• Racism, Sexism, and Ethnocentrism: Individuals with high SDO are more likely to hold discriminatory attitudes against racial, ethnic, and gender minority groups.
• Prejudice Against Subordinate Groups: SDO specifically predicts prejudice against groups that are low in status or perceived as subordinate.
• Support for Discriminatory Policies: This orientation translates into support for policies that actively disadvantage certain groups or justify their lower status.

Research suggests that SDO can mediate the effect of a person's social position on their level of prejudice, meaning that one's place in the social hierarchy can influence their SDO, which in turn influences their prejudiced attitudes. High-SDO individuals may use stereotypes as "legitimizing myths" to justify negative attitudes and discrimination.

SDO and Political Attitudes

SDO correlates robustly with a wide range of political and social attitudes, particularly those related to the distribution of power and resources:

• Conservatism: High SDO is consistently tied to more conservative political ideologies, especially economic conservatism.
• Hierarchy-Enhancing Policies: People with high SDO tend to support policies that reinforce societal hierarchies, such as harsh punishment for criminals, increased military spending, and policies that restrict civil rights for certain groups.
• Opposition to Social Equality Initiatives: They are less likely to support initiatives aimed at reducing inequality, such as social welfare programs or affirmative action.

It's important to note that SDO is distinct from Right-Wing Authoritarianism (RWA), another psychological construct related to prejudice. While both predict negative attitudes towards outgroups, SDO is more about maintaining group-based dominance, whereas RWA is more about adherence to traditional norms and submission to authority.

Can SDO Change?

While SDO is considered a relatively stable individual difference, there's ongoing research into its flexibility. Some studies suggest that:

• Contextual Influences: While an individual's rank order on SDO tends to be stable across contexts, situational factors can influence the salience of dominance motives and their predictive power.
• Interventions: Preliminary evidence suggests that certain experiences, like service-learning, might potentially reduce levels of SDO. Challenging legitimizing ideologies can also lead to rejection of these views, particularly for those already low in SDO.

Ultimately, understanding SDO is crucial for comprehending the psychological roots of inequality and intergroup conflict. While it describes a deeply ingrained individual preference, recognizing its influence can help us better understand societal dynamics and work towards more equitable and inclusive communities.
