Title
Lexical convergence inside and across echo chambers.
Abstract
Recent studies, targeting Facebook, showed the tendency of users to interact with information adhering to their preferred narrative and to ignore dissenting information. Confirmation bias seems to account for user decisions about consuming and spreading content and, at the same time, aggregation of favored information within groups of like-minded people (echo chambers) reinforces selective exposure and group polarization. To gain a deeper understanding of the perspectives of these clustered communities, in this work we analyze the language of users engaged in the echo chambers emerging on Facebook around two distinct and conflicting narratives -- i.e., Science and Conspiracy news. Despite the high level of segregation of such communities, we show that users from both the echo chambers adopt very similar vocabularies and use the same word with almost the same frequency in their commenting activity, both at the individual and the collective level. Moreover, zooming in at the conversation level, we observe the emergence of lexical convergence between users who consistently interact with each other through co-commenting activity not only inside, but also across the echo chambers. Thus, the fact that even users with opposite views gradually coordinate their linguistic behavior when joining a discussion, suggests that users always aim to achieve communication when engaging in a conversation.
