Recent political trends and events have been marked by strong educational differences. In addition, education has also been shown to be a basis for group identity and group conflict. In this paper, we argue that educational groups are likely to understand their position in society and their inclusion or exclusion (in politics) as being related to their educational level. Thus, it is likely that education-based affective attitudes are related to evaluations of the societal and political status quo. Using data from nine European countries, this article charts the relationships of higher educated-bias (i.e., the preference for higher educated compared to less educated groups) with different political outcomes. In analyses of preregistered hypotheses, we demonstrate that the higher educated show ingroup bias, in particular those who identify strongly with their educational group. The less educated do not show (significant) ingroup bias. Those who have a stronger (positive) bias towards the higher educated display more political trust and satisfaction with democracy, and are less likely to be populist. We measured support for populism in four different ways with populist attitudes, populist voting, affective attitudes towards populist party supporters compared with mainstream party supporters, and identification with ‘the common people.’
