Abstract

Recently, substantial attention has been paid to the spread of highly partisan and often factually incorrect information (i.e., so-called “fake news”) on social media. In this study, we attempt to extend current knowledge on this topic by exploring the degree to which individual levels of ideological extremity, social trust, and trust in the news media are associated with the dissemination of countermedia content, or web-based, ideologically extreme information that uses false, biased, misleading, and hyper-partisan claims to counter the knowledge produced by the mainstream news media. To investigate these possible associations, we used a combination of self-report survey data and trace data collected from Facebook and Twitter. The results suggested that sharing countermedia content on Facebook is positively associated with ideological extremity and negatively associated with trust in the mainstream news media. On Twitter, we found evidence that countermedia content sharing is negatively associated with social trust.

人们为什么在社交媒体上分享意识形态上极端，虚假和误导性的内容？基于自我报告和跟踪数据的Facebook和Twitter上反媒体内容传播的分析

摘要

近来，已经高度关注社交媒体上的高度党派和通常事实不正确的信息（即所谓的“假新闻”）的传播。在本研究中，我们试图通过探索意识形态极端性，社会信任和对新闻媒体的信任的各个级别与反媒体内容或基于网络的意识形态极端性的传播相关联的程度，来扩展有关该主题的当前知识。使用虚假，有偏见，误导性和超党派主张的信息来反驳主流新闻媒体产生的知识。为了调查这些可能的关联，我们使用了自报告调查数据和从Facebook和Twitter收集的跟踪数据的组合。结果表明，在Facebook上共享反媒体内容与意识形态极端性正相关，而与主流新闻媒体的信任度负相关。在Twitter上，我们发现证据表明，反媒体内容共享与社会信任度负相关。
