摘要

当今的高选择性数字媒体环境允许公民完全不接触网络新闻，即使使用新闻，也会选择与其意识形态偏好一致的新闻来源。然而，由于测量问题和跨国差异，最近的研究对意识形态自我选择到志同道合的网络新闻的普遍性还没有定论。我们引入了一种多方法设计，将来自六个主要民主国家的 7000 多名参与者的网络浏览历史和调查反馈与监督文本分类相结合，将政治新闻与非政治新闻的接触区分开来。我们发现，与非政治性网络新闻相比，政治性网络新闻的曝光率要低得多，而且受到更强的意识形态自我选择的影响，尤其是在美国。通过强调政治新闻内容的特殊作用，研究结果加深了人们对网络新闻曝光率和数字媒体在民主中作用的理解。

Ideological self-selection in online news exposure: Evidence from Europe and the US

Today’s high-choice digital media environments allow citizens to completely refrain from online news exposure and, if they do use news, to select sources that align with their ideological preferences. Yet due to measurement problems and cross-country differences, recent research has been inconclusive regarding the prevalence of ideological self-selection into like-minded online news. We introduce a multi-method design combining the web-browsing histories and survey responses of more than 7000 participants from six major democracies with supervised text classification to separate political from nonpolitical news exposure. We find that political online news exposure is both substantially less prevalent and subject to stronger ideological self-selection than nonpolitical online news exposure, especially in the United States. By highlighting the peculiar role of political news content, the results improve the understanding of online news exposure and the role of digital media in democracy.
