Research suggests that different motivational dynamics underlie right-wing authoritarianism (RWA) and social dominance orientation (SDO). These differences may be framed in the theory of basic human values. RWA may trace back to conservation versus openness-to-change values, and SDO to self-enhancement versus self-transcendence values. Based on a large-scale German survey, associations of RWA a...

Research on intergroup ideologies (colorblindness, multiculturalism) has increased our understanding of intergroup attitudes. This article reports empirical tests of the relation between a newly studied ideology, polyculturalism (ideology focusing on interactions and connections among racial/ethnic groups), and intergroup attitudes. Across four studies (with racially/ethnically diverse U.S. und...

Psychologists know a lot about the political and ideological correlates of people scoring high on authoritarianism. However, psychologists have less knowledge about such people's everyday pursuits. In the present study, the authors examined authoritarian interest in film, live events, music, and reading. A predictable pattern of correlates emerged. For example, authoritarians enjoyed activities...

Research has shown that in-group favoritism is associated with concerns over the maintenance of social norms. Here we present two studies examining whether genetic factors underpin this association. A classical twin design was used to decompose phenotypic variance into genetic and environmental components in two studies. Study 1 used 812 pairs of adult U.S. twins from the nationally representat...

Are the sources of ethnocentrism rather more sociological than psychological in nature? In order to answer this question, we review a classic debate between sociologists and psychologists. From this debate we distil two implicit theoretical models which are transposed into explicit and competitive models. A number of lacunas are filled with recent theoretical contributions and, subsequently, th...

Citizens who expressed concerns about immigration to the U.K. were more likely to vote to leave. Two correlational studies examined the previously unexplored question of whether the Brexit vote and support for the outcome of the E.U....
