Abstract
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.
Highlights
The World Wide Web has changed the dynamics of information transmission as well as the agenda-setting process [1]
According to literature on opinion dynamics [37], in particular the one related to the Bounded confidence model (BCM) [51]—two individuals are able to influence each other only if the distance between their opinion is below a given distance—users consuming different and opposite information tend to aggregate into isolated clusters. We measure their commenting activity on the opposite category finding that polarized users of conspiracy news are more focused on posts of their community and that they are more oriented on the diffusion of their contents—i.e. they are more prone to like and share posts from conspiracy pages
Usual consumers of scientific news result to be less committed in the diffusion and more prone to comment on conspiracy pages
Summary
The World Wide Web has changed the dynamics of information transmission as well as the agenda-setting process [1]. In particular when related to social relevant issues, mingle with half-truths and untruths to create informational blends [2, 3]. In such a scenario, as pointed out by [4], individuals can be uninformed or misinformed and the role of corrections in the diffusion and formation of biased beliefs are not effective. We address users consumption patterns of information using very distinct type of contents—i.e., main stream scientific news and conspiracy news The former diffuse scientific knowledge and the sources are easy to access. Conspiracy theses tend to reduce the complexity of reality by explaining significant social or political aspects
