概要	The Political Tolerance Scale measures willingness to permit unpopular groups to exercise civil liberties and political rights, including free speech, assembly, and voting rights even for groups the respondent strongly opposes. Pioneered by Stouffer (1955) measuring tolerance of communists during McCarthyism and extended by Gibson (1989) and Sullivan, Piereson, and Marcus (1982), the scale assesses fundamental democratic commitment—that pluralism and minority rights supersede majoritarian preference. It addresses the paradox: can democracy survive if majorities vote to restrict minority rights? Tolerance is essential for democratic stability, particularly as polarization increases.	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.
