Interesting academic papers about comment sections


Great list. Excuse me if I duplicate, but here are a few additions:

Many from the Engaging News Project by Stroud et al test how to improve comments sections (

e.g., Stroud, N. J., Scacco, J. M., Muddiman, A., & Curry, A. L. (2015). Changing deliberative norms on news organizations’ Facebook sites. Journal of Computer‐Mediated Communication, 20(2), 188-203.

There’s also some work on how comments influence perceptions of news content, e.g.,

Anderson, Ashley A., et al. “The “nasty effect:” online incivility and risk perceptions of emerging technologies.” Journal of Computer‐Mediated Communication 19.3 (2014): 373-387.

Kümpel, A. S., & Springer, N. (2016). Commenting quality: Effects of user comments on perceptions of journalistic quality. Studies in Communication|Media, 5(3), 353-366.

Prochazka, F., Weber, P., & Schweiger, W. (2016). Effects of civility and reasoning in user comments on perceived journalistic quality. Journalism Studies, 1-17.

And the reverse, how other content influences perceptions of comments and commenters (full disclosure, this is my work; hopefully it has some relevance here):

Veenstra, A. S., Park, C. S., Lyons, B. A., Kang, C. S., & Iyer, N. (2015). Intramedium interaction and the third-person effect: how partisans respond to youtube ads and comments. Cyberpsychology, Behavior, and Social Networking, 18(7), 406-410.

Lyons, B. A., & Veenstra, A. S. (2016). How (Not) to Talk on Twitter: Effects of Politicians’ Tweets on Perceptions of the Twitter Environment. Cyberpsychology, Behavior, and Social Networking, 19(1), 8-15.

Here’s a paper analyzing 126 submissions on how to improve comment spaces on news articles: FROM PUBLIC SPACES TO PUBLIC SPHERE by Rodrigo Zamith & Seth C. Lewis.

“Four main themes emerged in the submissions: a need to (1) better organize content, (2) moderate content more effectively, (3) unite disjointed discourse, and (4) increase participation while promoting diversity. We find in these proposed solutions the possibility for relatively low-cost, easy-to-build systems that could moderate comments more efficiently while also facilitating more civil, cohesive, and diverse discourse; however, we also find the lingering danger of designing new systems that could perpetuate old problems such as fragmentation, filter bubbles, and homogenization.”

Constructing the cyber-troll: Psychopathy, sadism, and empathy
Natalie Sesta and Evita March, Federation University, School of Health Science and Psychology, Australia

• Trolling is an online antisocial behaviour with negative psychological outcomes.
• Current study predicted trolling perpetration from gender and personality.
• Trolls more likely to be male with high levels of trait psychopathy and sadism
• Trolls have lower affective empathy, and psychopathy moderates cognitive empathy.
• Results have implications for establishing education and prevention programs.


A low standard of comments increases the reading by those who already participate but “non-users are even more frustrated by the low quality of discussions. They consider such participation activities to be a waste of time, and are not willing to register.”

Using eight months of online comments on New York Times articles, we find that only 28% of commenters of identifiable gender are female, but that their comments receive more recommendations from other readers…We discuss the implications of these gender differences for democratic discourse and suggest ways to increase gender parity.

You Can’t Stay Here: The Efficacy of Reddit’s 2015 Ban Examined Through Hate Speech

This paper looks at the success of Reddit’s closing of communities filled with hate speech in reducing hate speech across the platform.

Key points:

The empirical work in this paper suggests that when narrowly applied to small, specific groups, banning deviant hate groups can work to reduce and contain the behavior.

The banning of r/fatpeoplehate and r/CoonTown led to the rise of alternatives on, for example, where the core group of users from Reddit reorganized. For instance, in another ongoing study, we observed that 1,536 r/fatpeoplehate users have exact match usernames on The users of the Voat equivalents of the two banned subreddits continue to engage in racism and fat-shaming [22, 45]. In a sense, Reddit has made these users (from banned subreddits) someone else’s problem. To be clear, from a macro persepctive, Reddit’s actions likely did not make the internet safer or less hateful. One possible interpretation, given the evidence at hand, is that the ban drove the users from these banned subreddits to darker corners of the internet.
