Misinformation poses an important challenge for democracy, yet political debates appear to have polarized citizens’ perceptions and responses to misinformation. In a first experiment administered during the 2021 Canadian federal election, respondents were asked how acceptable it is for politicians to spread false information on climate change and COVID-19 for randomly assigned purposes. While most citizens considered misinformation unacceptable, opposing government action on these issues and having a right-wing ideology were associated with greater tolerance. I investigate these ideological differences further using observational and experimental data collected during the 2022 Quebec provincial election. I demonstrate that right-wing citizens are less likely to believe in the existence of an impartial truth, more indifferent to misinformation, and less supportive of measures to combat it than left-wing citizens. These patterns may partly reflect perceptions on the right that public discourses about misinformation are biased against them. The findings suggest that combatting misinformation has become a negatively valenced concept on the right and highlight how the politicization of misinformation debates can influence our ability to respond to it.
