Social media sites can bring people together or push them further apart. A modeling study shows how small changes in posting or recommendation rules can flip a system from consensus to polarization. In PNAS Nexus: https://ow.ly/hLrY50Y3KPk

Para quienes habláis español: si queréis saber más sobre la polarización y la difusión de información en redes sociales, aquí tenéis una nota de prensa sobre nuestro estudio reciente. www.unizar.es/actualidad/v... @ymoreno.bsky.social and @kleber-ao.com www.unizar.es/actualidad/v...

We link virality and polarization. An ABM calibrated on Brexit and Vaccine debates shows the same parameters that generate cascades also generate polarized opinions. Thanks to @ymoreno.bsky.social and @kleber-ao.com academic.oup.com/pnasnexus/ar...

Mechanistic interplay between information spreading and opinion polarization

Abstract. We investigate how information-spreading mechanisms affect opinion dynamics and vice versa via an agent-based simulation on adaptive social netwo

Verified users on social media networks drive polarization and the formation of echo chambers, study finds

When X (formerly Twitter) changed its verification system in 2022, many foresaw its potential to impact the spread of political opinions on the platform. In a modeling study published October 22 in iS...

What happens when a policy changes but the data is no longer available? We need to look at the mechanisms instead. In our newest pre-print (arxiv.org/abs/2312.09358), we study the effects of inadvertent social media content promotion on polarization & formation of echo chambers 1/4
