获得多样化的新闻可以加强民主公民身份。数字技术是缩小了还是扩大了新闻的范围，这引发了激烈的争论。先前的研究表明，数字新闻来源的丰富可能会导致受众更加分散、意识形态隔离和回音室。我们的研究采用了前所未有的数据组合来表明，移动访问新闻的增加实际上导致了更多的内容多样性，而意识形态的自我选择只能解释一小部分新闻共同曝光。我们还发现，在美国，超过一半的互联网用户不使用在线新闻。未来的研究应避免仅从桌面数据进行概括，并关注知情公民和新闻回避者之间日益扩大的鸿沟。丰富的媒体选择是当今信息环境的一个主要特征。许多通常基于对纯桌面新闻使用的分析的报告表明，这种增加的选择导致了受众的分裂、意识形态的隔离和没有交叉曝光的回音室。与许多这样的说法相反，本文使用观察性的多平台数据来捕获桌面和移动设备的使用情况，以证明共同接触各种新闻的情况正在上升，而意识形态的自我选择并不能解释大部分的共同接触。我们的研究表明，主流媒体提供了一个共同点，让意识形态各异的受众在网上汇聚在一起，尽管我们的分析还显示，超过一半的美国网民不消费在线新闻，这突显了信息不平等加剧的风险，这种风险是由根据兴趣进行的自我选择所驱动的。在这项研究中，我们使用了来自美国的前所未有的观测数据组合，包括一个5 y的时间窗口，涉及数万名小组成员。我们的数据集追踪了不同设备上的新闻消费，并揭示了使用多平台或仅使用桌面访问时新闻饮食的重要差异。我们讨论了我们的研究结果对我们如何看待当前的传播环境、新闻曝光以及正在进行的限制错误信息影响的尝试的影响。
Access to diverse news strengthens democratic citizenship. Whether digital technologies have narrowed or widened news diets fosters contentious debates. Previous research shows the abundance of digital news sources might be leading to more fragmented audiences, ideological segregation, and echo chambers. Our study resorts to an unprecedented combination of data to show that the increase in mobile access to news actually leads to higher exposure to diverse content and that ideological self-selection explains only a small percentage of co-exposure to news. We also find that more than half of Internet users in the United States do not use online news. Future research should avoid generalizations from desktop-only data and pay attention to the increasing divide between informed citizens and news avoiders. The abundance of media options is a central feature of today’s information environment. Many accounts, often based on analysis of desktop-only news use, suggest that this increased choice leads to audience fragmentation, ideological segregation, and echo chambers with no cross-cutting exposure. Contrary to many of those claims, this paper uses observational multiplatform data capturing both desktop and mobile use to demonstrate that coexposure to diverse news is on the rise, and that ideological self-selection does not explain most of that coexposure. We show that mainstream media outlets offer the common ground where ideologically diverse audiences converge online, though our analysis also reveals that more than half of the US online population consumes no online news, underlining the risk of increased information inequality driven by self-selection along lines of interest. For this study, we use an unprecedented combination of observed data from the United States comprising a 5-y time window and involving tens of thousands of panelists. Our dataset traces news consumption across different devices and unveils important differences in news diets when multiplatform or desktop-only access is used. We discuss the implications of our findings for how we think about the current communication environment, exposure to news, and ongoing attempts to limit the effects of misinformation.
