Abstract

The spread of fake news on social media became a public concern in the United States after the 2016 presidential election. We examined exposure to and sharing of fake news by registered voters on Twitter and found that engagement with fake news sources was extremely concentrated. Only 1% of individuals accounted for 80% of fake news source exposures, and 0.1% accounted for nearly 80% of fake news sources shared. Individuals most likely to engage with fake news sources were conservative leaning, older, and highly engaged with political news. A cluster of fake news sources shared overlapping audiences on the extreme right, but for people across the political spectrum, most political news exposure still came from mainstream media outlets.

摘要

2016年总统大选后，社交媒体上虚假新闻的传播成为美国公众关注的问题。我们调查了注册选民在推特上接触和分享虚假新闻的情况，发现与虚假新闻来源的互动极为集中。仅1%的人占了虚假新闻来源曝光量的80%，而0.1%的人占了虚假新闻来源分享量的近80%。最有可能与虚假新闻来源互动的人倾向保守、年龄较大且高度关注政治新闻。一群虚假新闻来源在极右翼拥有重叠的受众，但对于政治光谱上的所有人来说，大多数政治新闻曝光仍来自主流媒体。
