One important driver of citizens’ political trust is opinion congruence, i.e., the extent to which citizens’ political preferences are in line with those of their representatives. Previous research on this relation has focused on either egocentric congruence (congruence with a citizen’s own position) or sociotropic congruence (congruence with the electorate overall). Departing from research on group-based representation deficits, we propose another possibility that has been overlooked so far: When evaluating trustworthiness, citizens rely on the extent to which their social group is substantively represented. In this contribution, we study the effect of such group-based congruence with regard to social classes in the European context. We hypothesize that the more distant the government is to the preferences of one’s social class, the lower an individual’s political trust. To study this relation, we combine individual-level data from the European Social Survey (ESS) with elite-level data from the Chapel Hill Expert Survey (CHES), measuring congruence on the left-right scale and on specific policy issues. Beyond adding a new perspective to research on congruence and political trust, we contribute to research on unequal congruence and responsiveness. This research has revealed how the preferences of socioeconomically disadvantaged classes are typically less well represented and influential than those of advantaged classes. Here, we ask whether this has implications for affected citizens’ political support in that members of classes whose preferences are not well represented have lower levels of political trust—and whether such class-based congruence matters above and beyond egocentric congruence.
