• The impact of dark tetrad traits on political orientation and extremism: an analysis in the course of a presidential election

In the present research (N = 675), we focus on the relationship between the dark side of human personality and political orientation and extremism, respectively, in the course of a presidential election where the two candidates represent either left-wing or right-wing political policies. Narcissism, Machiavellianism, psychopathy, and everyday sadism were associated with right-wing political orientation, whereas narcissism and psychopathy were associated with political extremism. Moreover, the relationships between personality and right-wing political orientation and extremism, respectively, were relatively independent from each other.

• Bad News for Conservatives? Moral Judgments and the Dark Triad Personality Traits: A Correlational Study

We found eleven significant correlations between conservative [Moral Intuition Survey] judgments and the Dark Triad – all at significance level of p<.00001 – and no significant correlations between liberal [Moral Intuition Survey] judgments and the Dark Triad. We believe that these results raise provocative moral questions about the personality bases of moral judgments. In particular, we propose that because the Short-D3 measures three “dark and antisocial” personality traits, our results raise some prima facie worries about the moral justification of some conservative moral judgments

• Does Lower Cognitive Ability Predict Greater Prejudice?

[T]here exists a solid empirical paper trail demonstrating that lower cognitive abilities (e.g., abstract-reasoning skills and verbal, nonverbal, and general intelligence) predict greater prejudice. We discuss how the effects of lower cognitive ability on prejudice are explained (i.e., mediated) by greater endorsement of right-wing socially conservative attitude. […]

Right-wing ideologies offer well-structured and ordered views about society that preserve traditional societal conventions and norms (e.g., Jost, Glaser, Kruglanski, & Sulloway, 2003). Such ideological belief systems are particularly attractive to individuals who are strongly motivated to avoid uncertainty and ambiguity in preference for simplicity and predictability (Jost et al., 2003; Roets & Van Hiel, 2011). Theoretically, individuals with lower mental abilities should be attracted by right-wing social-cultural ideologies because they minimize complexity and increase perceived control (Heaven, Ciarrochi, & Leeson, 2011; Stankov, 2009). Conversely, individuals with greater cognitive skills are better positioned to understand changing and dynamic societal contexts, which should facilitate open-minded, relatively left-leaning attitudes (Deary et al., 2008a; Heaven et al., 2011; McCourt, Bouchard, Lykken, Tellegen, & Keyes, 1999). Lower cognitive abilities therefore draw people to strategies and ideologies that emphasize what is presently known and considered acceptable to make sense and impose order over their environment. Resistance to social change and the preservation of the status quo regarding societal traditions—key principles underpinning right-wing social-cultural ideologies—should be particularly appealing to those wishing to avoid uncertainty and threat.

Indeed, the empirical literature reveals negative relations between cognitive abilities and right-wing social-cultural attitudes, including right-wing authoritarian (e.g., Keiller, 2010; McCourt et al., 1999), socially conservative (e.g., Stankov, 2009; Van Hiel et al., 2010), and religious attitudes (e.g., Zuckerman, Silberman, & Hall, 2013).
