Abstract

This study examines the relationship between misinformation and political intolerance during the 2022 Brazilian Election. Using a three-wave survey, we show that citizens who believe false claims about electoral fraud become more intolerant toward political opponents over time. Beliefs in electoral misinformation consistently predicted increases in intolerance over the course of the election. We find an indirect effect for using messaging apps for news and intolerance, mediated by beliefs in electoral misinformation, suggesting that citizens who rely on messaging apps for news are not only more susceptible to believing misinformation but also to its detrimental effects on democracy. These findings highlight electoral misinformation as a key driver of intolerant attitudes in polarized democracies, operating not only by eroding trust in institutions but also by undermining citizens’ commitment to democratic norms.
