Analyzing political conservatism as motivated social cognition integrates theories of personality (authoritarianism, dogmatism-intolerance of ambiguity), epistemic and existential needs (for closure, regulatory focus, terror management), and ideological rationalization (social dominance, system justification). A meta-analysis (88 samples, 12 countries, 22,818 cases) confirms that several psychological variables predict political conservatism: death anxiety (weighted mean r ϭ .50); system instability (.47); dogmatism-intolerance of ambiguity (.34); openness to experience (-.32); uncertainty tolerance (-.27); needs for order, structure, and closure (.26); integrative complexity (-.20); fear of threat and loss (.18); and self-esteem (-.09). The core ideology of conservatism stresses resistance to change and justification of inequality and is motivated by needs that vary situationally and dispositionally to manage uncertainty and threat.Conservatism is a demanding mistress and is giving me a migraine.-George F. Will, BuntsFor more than half a century, psychologists have been tracking the hypothesis that different psychological motives and tendencies underlie ideological differences between the political left and the right. The practice of singling out political conservatives for special study began with Adorno, Frenkel-Brunswik, Levinson, and Sanford's (1950) landmark study of authoritarianism and the fascist potential in personality. An asymmetrical focus on right-wing authoritarianism (RWA) was criticized heavily on theoretical and methodological grounds (e.g., Christie, 1954;Eysenck, 1954;Rokeach, 1960;Shils, 1954), but it has withstood the relentless tests of time and empirical scrutiny (e.g., Altemeyer, 1981Altemeyer, , 1988Altemeyer, , 1996Altemeyer, , 1998Billig, 1984;Brown, 1965;Christie, 1991;Elms, 1969;Sidanius, 1985;W. F. Stone, 1980;W. F. Stone, Lederer, & Christie, 1993;Tetlock, 1984;Wilson, 1973c). A voluminous literature, which we review here, facilitates the comparison of cognitive styles and motivational needs of political conservatives with those of moderates, liberals, radicals, and left-wingers. In addition to classic and contemporary approaches to authoritarianism, we cover less obvious sources of theory and research on individual differences associated with dogmatism and intolerance of ambiguity, uncertainty avoidance, need for cognitive closure, and social dominance orientation (SDO) insofar as each of these psychological variables contributes to a deeper and more nuanced understanding of political conservatism.The study of authoritarianism and other personality theories of political attitudes is often dismissed a priori as an illegitimate, value-laden attempt to correlate general psychological profiles with specific ideological beliefs (e.g., Durrheim, 1997; J. L. Martin, 2001;Ray, 1988). The psychological study of ideological conservatism is one that invites controversy (e.g., Redding, 2001;Sears, 1994;Sidanius, Pratto, & Bobo, 1996;Sniderman & Tetlock, 1986;Tetlock, 1994;Tetlock & Mitchell,...
