Abstract
Right–left political views can be decomposed into distinct economic and social dimensions that bear differing relations with external criteria. In three community samples (total N = 1,487), we identified replicable suppressor situations in which statistically controlling for either social or economic political ideology increased the other ideology dimension’s relations with variables reflecting cognitive rigidity, authoritarianism, dangerous worldview, and lethal partisanship. Specifically, positive bivariate relations between social conservatism and these outcomes were enhanced after controlling for economic conservatism, whereas, after controlling for social conservatism, positive bivariate relations between economic conservatism and external criteria became negative and negative bivariate relations were enhanced. We identified similar, albeit less consistent, suppressor phenomena for general personality. Taken together, our results suggest that social and economic conservatism differ substantially in their psychological implications, and that following statistical control, these differences emerge in samples in which social and economic conservatism are highly positively correlated.
