The spread of misinformation about COVID-19 vaccines threatens to prolong the pandemic, with prior evidence indicating that exposure to misinformation has negative effects on intent to be vaccinated. We describe results from randomized experiments in the United States (n = 5,075) that allow us to measure the effects of factual corrections on false beliefs about the vaccine and vaccination intent. Our evidence makes clear that corrections eliminate the effects of misinformation on beliefs about the vaccine, but that neither misinformation nor corrections affect vaccination intention. These effects are robust to formatting changes in the presentation of the corrections. Indeed, corrections without any formatting modifications whatsoever prove effective at reducing false beliefs, with formatting variations playing a very minor role. Despite the politicization of the pandemic, misperceptions about COVID-19 vaccines can be consistently rebutted across party lines.

事实更正消除了对 COVID-19 疫苗的错误信念

有关 COVID-19 疫苗的错误信息的传播有可能延长大流行，先前的证据表明，接触错误信息会对接种疫苗的意图产生负面影响。我们描述了在美国 (n = 5,075) 进行的随机实验的结果，这些实验使我们能够测量事实校正对疫苗和疫苗接种意图的错误信念的影响。我们的证据清楚地表明，纠正消除了错误信息对疫苗信念的影响，但错误信息和纠正都不会影响疫苗接种意图。这些效果对于更正表示中的格式更改是稳健的。事实上，没有任何格式修改的更正证明在减少错误信念方面是有效的，格式变化起着非常小的作用。
