Communal Quirks and Circlejerks: A Taxonomy of Processes Contributing to Insularity in Online Communities

Abstract

Online communication offers the potential for bridging con-nections, exposing users to new views and experiences by fostering socially heterogenous communities. However, in the absence of deliberate attempts to promote diversity, communities may tend towards insularity: a state where members and content are similar or homogenous, and where deviation from these norms is discouraged. This paper presents a taxonomy of processes contributing to insularity, synthesizing findings from a broader longitudinal interview study on engagement with online communities over time with previous literature. Using thematic analysis, sixteen processes were identified which were associated with four broad stages: formation (selective connections, network homophily, shared interests, audience segmentation); propagation (circlejerking, upholding community standards, avoiding conflict, tailoring content); reaction (individual avoidance, collective reaction, mocking deviance, derogating outsiders); and perpetuation (modelling, prior feedback, echo chambers, gatekeeping). These findings highlight the need to consider more diverse mechanisms by which communities become insular, and the role that platform features play in facilitating these processes.

Political Bias and Factualness in News Sharing across more than 100,000 Online Communities

“…Others have examined bias in moderation of content, as opposed to biased content or news sources themselves Wilson 2019, 2020). Echo chambers are a major consideration in understanding polarization, with papers focusing on their development (Allison and Bussey 2020) and the role of news sources in echo chambers (Horne, Nørregaard, and Adali 2019). Others have examined who shares what content with what political bias, but did so using implicit community structure (Samory, Abnousi, and Mitra 2020b).…”

Making Online Communities ‘Better’: A Taxonomy of Community Values on Reddit

“…One member of /r/Seattle wrote that "too many people from outside Seattle comment on posts in this subreddit." In any community with a specific subject, some degree of boundaries for membership are natural, yet too much insularity in online communities can be harmful (Allison and Bussey 2020).…”
