We know that emotions matter in politics, but less is known about the role of individual affective styles (i.e., the individual way of processing and responding to emotions). Building on the Process Model of Emotional Regulation (PMER), we report on two studies exploring the relationship between affective style (i.e. tolerating, adjusting, and concealing) and social and political trust. First, based on large-n survey data from Denmark (N=1048) and the United States (N=1046), we show strong cross-country similarities that adjusting positively predicts trust, while concealing negatively correlates with trust. Second, in a laboratory experiment (N=152), we conclude that concealing individuals are most influenced by emotions and contribute significantly less in a public goods game. In sum, combining various methodologies, we pioneer conclusions, showing affective style is a salient predictor for trust. We conclude by setting a research agenda for the inclusion of affective style in future studies in politics.
