The consequences of political disagreement in interpersonal communication: New insights from a comparative perspective

Political disagreement in interpersonal communication increases attitudinal ambivalence and can depress voter turnout. These effects seem to be driven by a wish to avoid social controversy rather than informational gains from encountering other opinions. This article shows that political disagreement in interpersonal communication increases the difficulty of deciding for which party to vote. Moreover, this effect is a result of social disapproval of one's party preference, while political expertise in interpersonal communication has no effect. For voter turnout, no direct effect of social disapproval of one's party preference is found. However, disapproval has an indirect influence on turnout via difficulty of vote choice. In sum, both political attitudes and political behaviour are affected by social pressures. Students of political attitudes and behaviour should try to include interpersonal discussion in their models in greater detail than is common practice today.
