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.

“大谎言”：事实核查如何影响对起义的支持

这项实验性调查探讨了选举舞弊事实检查和认知处理方式对参与者对 2020 年美国总统大选合法性的信心以及 1 月 6 日国会山袭击事件特征的影响。结果表明，事实核查、准确性动机推理和系统处理对参与者的合法性水平产生了积极影响，尤其是在共和党人中。我们还发现，参与者的系统处理、与民主党的联系以及对唐纳德特朗普的负面态度与他们将 1 月 6 日国会山袭击事件描述为暴力和极端有关。总体而言，这些结果支持动机推理和双重过程模型，但党派动机推理发挥了最大的作用。更远，
