Here, we study the emergence of joint opinion polarization and network segregation in online social media, specifically focusing on the interplay between the mechanisms of influence and unfriending. We say that a hashtag is adopted by a user if it is found either in tweets retweeted by the user (incoming edges), or in tweets by the user that were retweeted by someone else (outgoing edges).

It is tempting to use our model to reproduce a few stylized facts about empirical echo chambers. If you enjoyed this article, subscribe to receive more just like it. More work is certainly needed to understand the relationship between online echo chambers and misinformation. Adamic, L. A., & Adar, E. (2003). https://www.tandfonline.com/doi/full/10.1080/1369118X.2018.1428656. Social influence and unfollowing accelerate the emergence of echo chambers. For example, it does not help to promote content that will be disregarded [76]. Observing first in a group, frames of reference are set up which determine subsequent reports when the individual observes alone (illustrating the factual basis for the contentions that supra-individual qualities arise in group situations). Mason, D.J. The joint effect of social influence and rewiring accelerates the joint emergence of both polarization and segregation (Fig. bring together cutting-edge basic research that examines the processes underpinni, influence and applied research that tests the impact of social influence on real world, attitudes and actions. The statements, opinions and data contained in the journals are solely For example, a student may alter his or her behavior to match that of other students in a class. Asch’s, (1956) studies showed the power of social influence to change people’s perceptions of, obedience studies highlighted just how far individuals were willing to, orders of an authority figure, while Moscovici and Faucheux (1972) illustrated the wa, which minorities could change the opinions of a majorit, applied nature and “real world” focus of social influence research, Lewin’s (1947) action, research on promoting offal consumption among housewives highlighted the wa. The … processes can be harnessed to change behaviour is addressed by the next four contributions. For example, news feed algorithms favor stories with which users are more likely to engage in the future, based on past engagement [22]. w do people choose which types of charity to support and which to neglect? Help us to further improve by taking part in this short 5 minute survey, Special Issues and Collections in MDPI journals, Effectiveness of the Execution and Prevention of Metric-Based Adversarial Attacks on Social Network Data. In b, we use the same network density as in a and plot means and standard deviations across 10 simulation runs. Gentzkow, M., & Shapiro, J. M. (2011). Gudjonsson, G. & Sigurdsson, J. The study of social influence is central to social psychology and to understanding group processes and intergroup relations.

We wish to examine the conditions under which opinion polarization and network segregation coevolve. While the Web and social media have often been hailed as striking examples of this principle in action [4, 5], some of the assumptions upon which these systems are predicated may harm the very diversity that makes them precious sources of collective intelligence [6].
