Analysis of Social Media Posts Reveals User Preference for Echo Chambers

We’re aware that communication extends beyond mere words. Facial expressions, intonations, hand gestures, and other nuances enrich our expressions. Yet, in the realm of social media, these subtleties are absent.

To date, there has been limited exploration into social media communication compared to traditional offline channels. In a recent study, Boleslaw Szymanski, Ph.D., and his team discovered that while the dynamics are akin, they yield distinct outcomes, contributing to the proliferation of polarized perspectives.

Szymanski, the Claire & Roland Schmitt Distinguished Professor of Computer Science and Director of the Network Science and Technology Center (NeST) at Rensselaer Polytechnic Institute, collaborated with postdoctoral research associate James Flamino and graduate student Mohammed Shahid Modi at Rensselaer for this research.

In-depth Analysis of Social Media Posts

The team scrutinized approximately 183 million posts on Parler, a social media platform catering to right-leaning users seeking an alternative to Twitter, and 702 million Twitter posts. Both datasets covered posts from September to December 2020.

On both platforms, users tended to gravitate towards popular opinions (a phenomenon known as homophily). Moreover, when confronted with dissenting views, users often abandoned the platforms altogether.

“In our earlier research, we examined the political perspectives of students on university campuses,” remarked Szymanski. “We found that student groups dominated by majority opinion holders exhibited greater stability and longevity. Similarly, in our recent study, we observed that Parler users aligned with the majority opinion tended to have more enduring membership and remained active on the platform for longer durations. These users typically represented the extreme right.”

“Content with liberal leanings represented a negligible portion of the overall content. However, Twitter users initially displayed a diverse range of political affiliations before gravitating towards either end of the political spectrum. The common trend observed was that users tended to align with like-minded groups or disengage entirely.”

High Dropout Rates on Social Media Platforms

The dropout rates on social media platforms, which carry lower social costs compared to universities, are significantly higher—approximately 80 to 100 times—highlighting the ease with which individuals can disengage from these platforms without risking long-term relationships.

This comparison holds significance in understanding trends in public opinion, shifts in perspectives, and the impact of social media on political discourse. Moreover, the absence of offline communication nuances complicates the assessment of online content authenticity.

“It is crucial not only to mitigate the shortcomings of social media but also to amplify its advantages,” emphasized Szymanski. “While social media facilitates the democratization of information, the propensity of users to seek out echo chambers exacerbates social divisions.”

Specifically, the study revealed that Twitter users segregated into two large groups, one favoring liberal news and the other conservative news. Conversely, Parler users predominantly belonged to a single, conservative-biased group.

Propensity for Fake News Engagement among Parler Users

Parler users were also more inclined to engage with or gravitate towards fake news, indicating a propensity to persist along the same path if initially exposed to misinformation.

Furthermore, Parler users with dissenting viewpoints were more susceptible to adopting and propagating fake news themselves, indicative of an echo chamber effect. Conversely, the fake news cohort on Twitter failed to attract a significant user base.

“As we anticipate another election cycle, it is imperative to consider the disruptive potential of unverified and biased news, especially in light of the impending surge in generative AI-generated ‘deep fake’ audio and video content, which reinforces existing biases,” noted Curt Breneman, Ph.D., Dean of Rensselaer’s School of Science. “Dr. Szymanski’s research provides valuable insights into this critical issue, and I hope his findings are taken into account by both social media users and regulators.”
