所谓的“假新闻”再次引发了人们对政治竞选中错误信息的普遍性和影响的担忧。鉴于这种材料广泛传播的可能性，我们研究了2016年美国总统竞选期间与分享虚假文章相关的个人层面特征。为此，我们将原始调查与Facebook个人资料数据中记录的受访者分享活动进行唯一关联。首先，我们发现分享这些内容是一个相对罕见的活动。保守派比自由派或温和派更有可能分享来自假新闻领域的文章，这些领域在2016年基本上是亲特朗普的。我们还发现了一个强烈的年龄效应，在控制了党派和意识形态之后仍然存在：平均而言，65岁以上的用户分享的来自假新闻领域的文章是最年轻年龄组的近7倍。
So-called "fake news" has renewed concerns about the prevalence and effects of misinformation in political campaigns. Given the potential for widespread dissemination of this material, we examine the individual-level characteristics associated with sharing false articles during the 2016 U.S. presidential campaign. To do so, we uniquely link an original survey with respondents' sharing activity as recorded in Facebook profile data. First and foremost, we find that sharing this content was a relatively rare activity. Conservatives were more likely to share articles from fake news domains, which in 2016 were largely pro-Trump in orientation, than liberals or moderates. We also find a strong age effect, which persists after controlling for partisanship and ideology: On average, users over 65 shared nearly seven times as many articles from fake news domains as the youngest age group.
