Political scientists generally agree that all individuals structure their cultural attitudes in the same unidimensional fashion. However, various populist radical right parties remarkably combine moral progressiveness with conservatism regarding immigration-related issues. This suggests that the structuring of cultural attitudes among the electorate may also be more complex than typically assumed. Applying Correlational Class Analysis to representative survey data, the study uncovers three cultural belief systems. For individuals adhering to an integrated one, all cultural attitudes are interdependent, as typically assumed. However, two alternative belief systems are also uncovered: intermediate and partitioned. In the latter, positions on one cultural attitude (e.g. ethnocentrism) are barely related to positions on others (e.g. rejecting Islam or opposing homosexuality). The existence of multiple cultural belief systems challenges the widely held assumption that all people organise their cultural attitudes similarly. Both political party agendas and individuals' education level and religion appear key to understanding variation in belief systems. KEYWORDS Belief systems; correlational class analysis; cultural issues; ethnocentrism; political attitudes; populist radical right parties; rejection of islam Political attitudes regarding cultural issues are an important focus in both scholarly and popular writing and feature prominently in contemporary political debates. Contrary to attitudes pertaining to the economic domain, cultural attitudes concern issues of individual freedom and cultural diversity. Economic issues differentiate parties and electorates that oppose redistribution from those supporting it, and consequently pit the economically strong against the economically weak in the so-called 'democratic class struggle' (Lipset 1960).
