Verified user algorithms on X increase polarization and echo chambers
A computational modeling study by researchers at George Mason University found that X's verification system, which prioritizes verified users' posts in algorithms, can increase polarization and trigger echo chambers, particularly when verified users hold entrenched ideological views. The researchers warn that the system could be exploited by users wishing to manipulate others' opinions.
What happened
Researchers at George Mason University used computational modeling to study how X's verification system, changed in 2022 to allow almost anyone to become verified, affects the spread of political opinions on the platform.
The study found that when verified users with entrenched opinions post content that is prioritized by X's algorithms, the system can increase polarization and trigger the formation of echo chambers.
Reported impact
The findings suggest that the side effect could be taken advantage of by users wishing to manipulate others' opinions, and indicate that verified users with ideological views play a crucial role in shaping the flow of information and opinions within the social network.
The researchers note that social media companies should be aware of the possible impact they have on political polarization and attempt to mitigate this within their algorithms.
Index analysis
The modeling showed that verified users can facilitate consensus if they are not stubborn in their opinions, but if verified users are ideologues with entrenched opinions, their presence can drive polarization.
When verified user ideologues held extreme views, their presence triggered echo chamber formation in addition to polarization, while verified centrist ideologues decreased polarization.
Governance controls
X's verification system has been open to almost anyone since 2022, and the platform has stopped providing researchers access to its data, limiting independent study of the system's actual impact on polarization.
