Podsumowanie	The System Justification Scale operationalizes system justification theory, introduced by Jost and Banaji (1994), which holds that people are motivated to defend, bolster, and rationalize the existing social, economic, and political status quo, even when doing so runs against their personal or group interest. The general version, refined by Kay and Jost (2003), is an 8-item self-report measure on which respondents rate agreement with statements such as 'In general, the American political system operates as it should' on a 7- or 9-point Likert scale.	The Social Dominance Orientation Scale (SDO) is a self-report measure developed by Pratto, Sidanius, Stallworth, and Malle in 1994 to assess individual differences in preference for group-based hierarchy and inequality. The scale measures the extent to which individuals support dominance of some groups over others, reject egalitarianism, and accept hierarchical social organization. It has become central to social dominance theory and is widely used in political psychology and intergroup relations research.
