Fact-checking Trump’s election lies can improve confidence in U.S. elections: Experimental evidence

As the 2020 campaign unfolded, with a mix of extraordinary embellishments and outright falsehoods, President Trump’s attacks on the integrity of the U.S. electoral system grew louder and more frequent. Trump-aligned Republican candidates have since advanced similar false claims in their own campaigns in the lead-up to the 2022 midterm elections. Scholars, election officials, and even fellow Republican leaders have voiced concerns that Trump’s rhetoric represents a profound threat to the well-being of U.S. democracy. To investigate the capacity for fact-checking efforts to repair the damage incurred by election-related misinformation, in the weeks before the 2020 election, we fielded a survey experiment on a nationally representative sample to test whether exposure to fact-checks of Trump’s false claims increased participants’ confidence in the integrity of the U.S. election and affected their voting behavior. Although our pre-registered analysis offered no evidence that corrections affect voting behavior, our findings do show that exposure to these fact-checks can increase confidence in the integrity of the 2020 U.S. election. However, the effects varied significantly by partisanship, with these changes concentrated among Democrats and Independents.
