Liberal-conservative asymmetries in anti-democratic tendencies are partly explained by psychological differences in a nationally representative U.S. sample

Based on theory and research in political psychology, we hypothesized that liberal-conservative differences in right-wing authoritarianism, social dominance orientation, and political system justification would contribute to asymmetries in anti-democratic tendencies. These hypotheses were tested in a nationally representative survey of U.S. adults (N = 1557). Results revealed that conservatives were less supportive of political equality and legal rights and guarantees and more willing to defect from democratic "rules of the game" and vote for anti-democratic candidates, even after adjusting for political extremism. Mediational analyses suggested that conservatives' anti-democratic tendencies were partially attributable to higher levels of right-wing authoritarianism and social dominance orientation. Conservatives also scored higher in political system justification, which was associated with support for free speech and mitigated anti-democratic tendencies. Democrats and Republicans who approved January 6, 2021, insurrectionists were more conservative and higher in right-wing authoritarianism than those who did not. Implications for social psychology and society are discussed.
