Partisan and non-partisan conspiracy theories’ diverging effects on political participation

What role do conspiracy theories play in mobilizing political action? Both historical and contemporary accounts have written on the role of conspiracy theories (CTs) in mobilizing various movements, including during the process of nation-building, regime consolidation, and in challenges to liberal democracy in more recent years. In contrast, recent empirical research suggests that beliefs in CTs might reduce participation in politics. However, both research genres have only analyzed a limited number of CTs. This article explores how belief in different CTs affects people’s likelihood to participate in politics, particularly in relation to partisan narratives. Using two surveys conducted in the United States (n=1200) and Turkey (n=1500) -two cases that approximate a most different system design-, it finds that beliefs in partisan CTs encourage citizens to participate in politics while the effect of beliefs in non-partisan CTs on political participation varies depending on the individual’s political affiliation.
