The association between system-justifying ideologies and attitudes toward the social market economy in Germany

Although the legitimacy of an economic system is often dependent on citizen support, psychological research has paid little attention to attitudes toward economic systems. In the present study, we examined the link between two system-justifying ideologies, namely, right-wing authoritarianism (RWA) and social dominance orientation (SDO), and attitudes toward the social market economy in Germany. Drawing on system justification theory, we hypothesized that RWA would be positively and SDO negatively associated with support for the social market economy because the social component of the German economic system conflicts with beliefs inherent in SDO favoring a group-based hierarchy. Based on a quota sample of German adults (N = 886), we found support for the predicted associations of both system-justifying ideologies with economic system support, except that RWA was negatively associated with support for the welfare component of the social market economy. However, the positive relationship of RWA with support for the social market economy only emerged after SDO was statistically controlled, suggesting a suppressor situation. These findings demonstrate that system-justifying ideologies bear different relations to pro-market attitudes depending on the type of economic regime. Implications for system justification theory are discussed. SUPPLEMENTARY INFORMATION: The online version contains supplementary material available at 10.1007/s12144-023-04483-7
