Social media users drive the spread of misinformation online by sharing posts
that include erroneous information or commenting on controversial topics with
unsubstantiated arguments often in earnest. Work on echo chambers has suggested
that users' perspectives are reinforced through repeated interactions with
like-minded peers, promoted by homophily and bias in information diffusion.
Building on long-standing interest in the social bases of language and
linguistic underpinnings of social behavior, this work explores how
conversations around misinformation are mediated through language use. We
compare a number of linguistic measures, e.g., in-/out-group cues, readability,
and discourse connectives, within and across topics of conversation and user
communities. Our findings reveal increased presence of group identity signals
and processing fluency within echo chambers during discussions of
misinformation. We discuss the specific character of these broader trends
across topics and examine contextual influences.

社交媒体用户通过分享包含错误信息的帖子或对有争议的话题发表无根据的论点来推动在线上的错误信息传播，在回声室中，由同质性和信息传播中的偏见推动，用户的观点通过与志同道合的同伴重复交互得到加强，本研究探讨了如何通过语言使用来调解围绕错误信息的对话，比较了对话和用户社区内外的多种语言度量，如内外群暗示、可读性和话语连接词，我们的研究发现，在讨论错误信息的回声室中增加了群体身份信号和处理流利度，我们还讨论了这些广泛趋势在不同话题和环境影响下的特点。
