“The Big Lie”: How Fact Checking Influences Support for Insurrection

This experimental investigation explores the influence of election fraud fact-checking and cognitive processing styles on participants’ confidence in the 2020 U.S. presidential election’s legitimacy and characterizations of the January Sixth Capitol Hill Attack. The results indicate fact-checking, accuracy motivated reasoning, and systematic processing exerted positive effects on participants’ legitimacy levels, especially among Republicans. We also found that participants’ systematic processing, affiliation with the Democratic Party, and negative attitudes toward Donald Trump were associated with their characterizations of the January Sixth Capitol Hill Attack as violent and extreme. Overall, these results support both motivated reasoning and dual process models, but partisan motivated reasoning exerted the greatest effects. Further, these findings suggest Republican and pro-Trump participants who rely on heuristic processing may find violent, extra-political actions acceptable means of attempting to achieve their goals.
