论文摘要
在社交媒体平台上增加了不信任信息的共享是我们现代信息社会的主要挑战之一。由于已知政治精英传播的信息会塑造公民和媒体的话语，因此检查政客共享的信息质量尤为重要。在这里，我们表明，从2016年开始，美国国会的共和党成员越来越多地与不信任的来源分享联系。共和党人与民主党人发布的不信任信息的比例正在以加速率分歧，自从拜登总统当选以来，这种分歧加剧了。政党之间的这种差异似乎是美国独有的，因为在德国和英国等其他西方民主国家无法观察到，左右差异较小，并且在很大程度上保持恒定。
Increased sharing of untrustworthy information on social media platforms is one of the main challenges of our modern information society. Because information disseminated by political elites is known to shape citizen and media discourse, it is particularly important to examine the quality of information shared by politicians. Here we show that from 2016 onward, members of the Republican party in the U.S. Congress have been increasingly sharing links to untrustworthy sources. The proportion of untrustworthy information posted by Republicans versus Democrats is diverging at an accelerating rate, and this divergence has worsened since president Biden was elected. This divergence between parties seems to be unique to the U.S. as it cannot be observed in other western democracies such as Germany and the United Kingdom, where left-right disparities are smaller and have remained largely constant.
