概要	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 Democratic Support Scale measures citizen commitment to democracy as a regime type, including beliefs that democracy is the best system of government, willingness to defend democratic institutions, and rejection of non-democratic alternatives. Pioneered by Norris (1999) and Dalton (2004) in comparative research, the measure distinguishes regime support (belief in democracy's superiority) from performance support (satisfaction with current government). It addresses the paradox of 'critical citizens'—in advanced democracies, people often express dissatisfaction with current government performance while maintaining deep commitment to democratic principles.
