Title: Deplatforming Right-Wing Extremists on Twitter Following the 
January 6 Insurrection

Abstract:

What happened when Twitter deplatformed 70,000 right-wing extremists 
following the January 6 insurrection? Using a panel of over a half 
million active Twitter users and a sharp regression discontinuity 
design, we test the causal effects of this intervention on the 
circulation of misinformation by those deplatformed, and by users from 
adjacent groups such as misinformation supersharers, QAnon traffickers 
and deplatformed users’ followers. We show that Twitter's intervention 
reduced misinformation on the site substantially by preventing the 
deplatformed users from spreading it. We also show that similar, 
non-deplatformed users exited the platform in response to the 
intervention. The results inform the historical record of the 
insurrection, a momentous event in U.S. history, and show the capacity 
of social media platforms to control public discourse.

* Joint work with Stefan D. McCabe, Diogo Ferrari, Jon Green and David 
M.J. Lazer.



------------------------------------
Sponsored by the UCR Data Science Center, the purpose of the Data 
Science talks is to foster collaborations between "core" Data Science 
faculty (from CSE/ECE/Stat Departments) and faculty/visitors from other 
sciences that face Data Science problems in their research. These 
informal gatherings are open to interested faculty and graduate 
students. Each meeting will start with a talk describing research 
problems and then a discussion will follow for questions, open problems, 
ideas for possible collaborations etc.

Please forward this email to other colleagues or graduate students in 
your lab that may be interested.

Moreover, if you are interested in giving a Data Science related talk, 
please contact me.

Sincerely,
Vassilis Tsotras
Professor, CSE Department
Director, Data Science Major
