Dislike and Dialogue: Antagonistic Reply Patterns and Rising Polarization in Online Comment Sections
SymposiumTalk-04
Presented by: Gerrit Anders
Social media research often emphasizes users’ preference for congeniality, with users preferentially consuming attitude-consistent information. Yet much less is known about the dynamics that arise when users engage not just with content but with one another. Drawing on large-scale data from two major news outlets – Spiegel Online and the Huffington Post – we examine how reply behavior unfolds in polarized online environments and how such behavior relates to polarization.
Across both platforms (each with more than 20 million comments), we find a consistent uncongeniality bias: users are more likely to reply to comments that are collectively disliked and replies typically invert the evaluative tone of their parent comments, indicating antagonistic response patterns. Replies also receive more extreme evaluations than the comments they address, suggesting localized polarization within threads. Finding these results across both platforms with different language and audiences indicates generalizable behavioral tendencies.
To complement these interaction-level patterns, we also analyze the longitudinal development of polarization. Tracking the variance and fragmentation of opinions, we observe a growing polarization over time independent of specific news topics.
Together, these findings provide large-scale, cross-platform evidence that everyday online discourse is shaped less by homophily than by engagement with disagreement. This leaves an important question. How can digital spaces be designed so that encounters with opposing views can happen while the current tendency toward escalating polarization is restrained?
