This project examines how political elites — drawing on a dataset of tweets by Donald Trump and members of the U.S. Congress — amplify conspiratorial narratives, and whether audiences exposed to such content display the patterns predicted by the monologicality thesis: the tendency for conspiracy believers to adopt mutually reinforcing beliefs across unrelated domains. We operationalize both conspiratorial narratives and monologicality to test these dynamics causally, addressing a gap in empirical research on elite-driven dissemination and contributing to ongoing debates about the conditions under which conspiracy beliefs take hold and spread in online environments.
