New paper out in Plos One !

By integrating group identities and affective polarization in opinion dynamics, we show that out-group intolerance is the main driver of ideological polarization.

One year in the making, eight authors, a truly collaborative effort. It's been a lot of work, but we hope the community will like it.

Comments welcome, RT appreciated!

[Valentin KILIAN @valentin_kilian]

Yesterday, I had the pleasure of presenting my work on "Anytime-valid, Bayes-assisted, Prediction-Powered Inference" at the @NewtonInstitute. This collaborative work is gaining significant attention.

The preprint is already available online: https://t.co/oK7gNo9mzQ.

Also featured in @PhysicsMagazine 😀

Happy to present my latest article in @PhysRevE ! In this paper, I show that the Voter Model can predict individual opinions in a large, heterogeneous online population.

[Antoine Vendeville @avdeville]

I study a retweet network collected during the 2017 French presidential elections where accounts of political entities are fixed as reference points. I show that in its equilibrium state, the Voter Model correctly identifies ground-truth opinions of more than 92% of the users.

Last week I presented our (@GiulioRossetti) open #Bluesky dataset @NetSciConf.
We release augmented, anonymized content and network data from 81% of users over a year.
The #dataset is available at https://t.co/hX4HKXH1jk

It turns out that the APS highlighted our work on echo chambers in signed networks almost a month ago, and I did not find out about this until today 🫢

[American Physical Society @APSphysics]

A new study using models based on disease spread shows both positive and negative interactions can drive #EchoChamber formation — where people only hear ideas that reinforce their own beliefs.

Read it in @PhysRevE: https://t.co/skpggADZCU

🌐 Don't miss the opportunity to submit your abstract at CCS25!

[Guillermo Romero @JuillermoRomero]

Happyly co-chairing 2 organised sessions with @TVGsociologist at the #Sunbelt2025 conference @SocNetAnalysts in Paris June 23-29

Our sessions are "Elite Networks" and "Network approaches to political dynamics". Only 4 days left to submit an abstract! https://t.co/8RYfjlqKsE

The elections have closed, the votes have been counted, and the new members are... 🥁🥁

@MarikaSa_ , Yasaman Asgari and Miguel A. González-Casado! We are excited to work with you the coming year! 🎉

[Fernando Díaz Díaz @FernandoDazDaz6]

🚨 New paper alert! 🚨 How do echo chambers form in signed networks? 🤔 A new study by @avdeville and myself explores the role of structural balance in shaping information flows and inducing echo chambers. 🧵👇

[Antoine Vendeville @avdeville]

Super proud of this work !

I show that the ubiquitous voter model can effectively predict individual opinions of Twitter users 😎

This marks a new step in the study of the empirical validity of theoretical models for opinion dynamics !
