This research examines how false beliefs shape perceptions of government transparency in times of crisis. Measuring transparency perceptions using both closed- and open-ended questions drawn from a Canadian panel survey, we show that individuals holding false beliefs about COVID-19 are more likely to have negative perceptions of government transparency. They also tend to rely on their false beliefs when asked to justify why they think governments are not being transparent about the pandemic. Our findings suggest that the inability to successfully debunk misinformation could worsen perceptions of government transparency, further eroding political support and contributing to non-compliance with public health directives.
