In a new study, researchers demonstrate that the updated verification system at X has indeed increased polarization and triggered the formation of echo chambers. Manipulating others and their opinions is now easier, scientists say.
After Elon Musk, a self-proclaimed free speech absolutist, bought Twitter and quickly changed its verification system, enabling almost anyone to acquire the cherished blue chip for money, he said he was hoping this would turn the platform into “a common digital town square.”

“There is currently great danger that social media will splinter into far right wing and far left wing echo chambers that generate more hate and divide our society,” wrote Musk back in 2022.
However, this is not how it has worked out – on the contrary, the side effect of allowing almost anybody to become verified has actually further increased polarization on X, say the researchers who published a modeling study in the Cell Press journal iScience on Tuesday.
“Our findings confirm that ideologues and verified users play a crucial role in shaping the flow of information and opinions within the social network,” said author Henrique Ferraz de Arruda, a computer scientist at George Mason University.
“When verified people post things, it can reach more people, which allows them to have a significant impact on the formation and reinforcement of echo chambers.”
Studying essentially anything on X, including the impact of changes in its verification system, is difficult because the platform no longer allows researchers to access its data.
Sure, in April 2023, when X was still called Twitter, NewsGuard, a startup that scans the web and rates the reliability of news sources, did say that the platform has allowed bad actors and peddlers of disinformation to spread fake or misleading content by purchasing a blue check mark.
But that’s an accusation rather than proper research. For the new study, researchers used a computational model simulating how people post and receive messages on social media platforms to investigate how having a larger number of verified users might impact polarization and the formation of echo chambers.
Within the model, they tweaked the number of verified users and also varied how stubborn these individuals were in their opinions.

The research showed that verified users can actually facilitate consensus on X if they are not stubborn in their opinions. However, if verified users are “ideologues” with entrenched opinions that they hope to disseminate, their presence can drive polarization.
What’s more, when verified user ideologues held extreme views, their presence triggered the formation of echo chambers in addition to driving polarization.
“When the number of ideologues in the network becomes sufficiently large, regardless of whether they exhibit centrist or extremist behavior, we observed that a significant portion of the messages exchanged in the network are either sent to or received from these influential users,” said Arruda.
“This suggests that, when social network algorithms prioritize visibility over content control, the users may be able to reach others to reinforce their opinions in groups, which could entrench echo chamber structures.”
The study was based on X’s framework but the researchers say that the results are probably also relevant to other social media platforms. However, Meta’s apps are now limiting political content as Mark Zuckerberg aims to avoid controversy.
