在线社交媒体上用户提供的大量内容促进了人们围绕共同的信仰、兴趣、世界观和叙事进行聚集。尽管人们热情洋溢地谈论所谓的集体智慧,但未经证实的谣言和阴谋论--例如化学痕迹、爬行动物或光明会--在在线社交网络(OSN)中随处可见。在这项工作中,我们对120万人的样本进行了研究,研究了与非常不同的叙事--即主流科学和阴谋新闻--相关的信息是如何被消费并塑造Facebook上的社区的。我们的结果表明,两极分化的社区出现在不同类型的内容周围,通常阴谋性新闻的消费者对其特定内容更加关注和独立。为了测试持续接触未经证实的谣言对用户内容选择造成的潜在偏见,我们总结了衡量用户对4709个巨魔信息的反应的分析--即对阴谋论的模仿和嘲讽。我们发现,77.92%的点赞和80.86%的评论来自通常与阴谋故事互动的用户。
The large availability of user provided contents on online social media facilitates people aggregation around shared beliefs, interests, worldviews and narratives. In spite of the enthusiastic rhetoric about the so called collective intelligence unsubstantiated rumors and conspiracy theories—e.g., chemtrails, reptilians or the Illuminati—are pervasive in online social networks (OSN). In this work we study, on a sample of 1.2 million of individuals, how information related to very distinct narratives—i.e. main stream scientific and conspiracy news—are consumed and shape communities on Facebook. Our results show that polarized communities emerge around distinct types of contents and usual consumers of conspiracy news result to be more focused and self-contained on their specific contents. To test potential biases induced by the continued exposure to unsubstantiated rumors on users’ content selection, we conclude our analysis measuring how users respond to 4,709 troll information—i.e. parodistic and sarcastic imitation of conspiracy theories. We find that 77.92% of likes and 80.86% of comments are from users usually interacting with conspiracy stories.
