Kudos to Juan Castillo

6/ Policy implication: early, proactive interventions matter. To unlock a silenced group, it’s not enough to “undo” a setting; we may need targeted rewiring and the right behavioural noise to cross basins of attraction.

5/ Why platforms should care: algorithms that intensify triadic closure can tip discourse into a silent-minority regime that doesn’t recover just by dialing the knob back. The return path is different—classic hysteresis.

4/ Nuance: moderate clustering protects minority expression by creating supportive local pockets; excessive clustering entrenches asymmetries (homophily amplification → core–periphery), making silence stickier

3/ Monte Carlo confirms it: the hysteresis loop persists in the stochastic system, narrower than mean-field, but still there. Structural (irregular topology, core–periphery patches) and behavioural noise helps the system escape or traps in some metastable states

2/ Mechanism in a nutshell: as triadic closure + choice homophily shape exposure, the expression dynamics undergo saddle bifurcations, creating multiple attractors. That’s the seed of path dependence and history-locked outcomes.

1/ 🧵 New preprint!
“Modeling Public Opinion Dynamics: The Spiral of Silence in Clustered Homophilic Networks”

arxiv.org/abs/2510.14098

We couple a clustered homophilic network model with a Q-learning “spiral of silence” dynamic uncovering hysteresis in public expression.

These oscillations offer a practical diagnostic of endogenous criticality in social contagion.
We test the method on real Twitter data distinguishing intrinsic transmissibility shifts from external shocks.

Kudos to Eva Rifá and Julian Vicens

We show that:
🔹 Targeted spreaders can extend or shorten rumor lifetime
🔹 Autocorrelation acts as an early warning signal near criticality
🔹 Only endogenous growth yields oscillatory autocorrelation (captured analytically via NIMFA)

New extended version of our preprint!
“Control strategies and virality detection using early warning signals in rumor models”

👉 arxiv.org/abs/2505.24795

We revisit the Maki–Thompson model to study rumor control and how to tell organic virality from astroturfing.

Las acampadas por Palestina fueron un golpe de aire fresco. Un atisbo de resistencia y humanidad. Vista la situación, el curso académico no debería empezar con normalidad en ningún sitio.

Ay, si hubiéramos tenido el vibe coding al alcance cuando éramos jóvenes y hacíamos cosas

Las protestas contra Israel obligan a suspender el final de la etapa de la Vuelta en Bilbao Las diferentes protestas de los aficionados contra Israel obligan a la organización a acabar la jornada tres kilómetros antes de la meta

Hasta que ese equipo siga ahí hay que sabotear la vuelta. Kilometro a kilometro.... Bueno, tres.

Tras todo lo que pasó antes, el boicot a Israel en la vuelta en Aragón se resuelve con unas cuantas banderas de Palestina en el recorrido? Ya vale de actos simbólicos.

Bruchinas de enero, tronadas de agosto,
¡tocad el tambor sin parar!

Palestina libre. Aragón nación!

Camaradas Aragonés. Las banderas palestinas al paso de la vuelta bien. Pero hay que cortarle el paso al equipo de Israel. Ese es boicot y acción directa.

Just wrote down equations with a gazillion indices to define something in a multiplex network. Felt young again, like during my PhD days.
My daughter promptly reminded me I’m not that young anymore.

Multiplex nostalgia: 1
Reality check: 1

Stop Israel's impunity!

Ahora lo progre es defender los derechos de autor? Qué mal todo

On my way to #NetSci2025 by train: 11 hours of low-emission travel and high-level procrastination recovery.
Still finishing my talks.
Sustainable science for professional procrastinators

Looking forward to our satellite on "Understudied Networks in Computational Social Science" next Tuesday (June 3) from 9am at @netsciconf.bsky.social

Join us for 10 great talks discussing (Meta)Decidem, Tiktok, Bluesky, Wikidata, Painters, and more!

YouTube video by Centre d'Estudis Unitat Popular (CEUP) Extrema dreta i xarxes socials: un espai en disputa — Emanuele Cozzo i Anna Carulla

Charla en el ciclo Antifeixisme a l'ofensiva del Centre de estudis Unitar Popular. El resumen de la chapa es: la cuestión no es el algoritmo, son las normas formales e informales que rigen el espacio. Y éstas, son una cuestión de hegemonía.

#JornadaComplexitat

Las centrales nucleares son como la derecha gobernado: las primeras en desconectarse, las últimas en volver. No ayudan nada en la recuperación y además producen escorias tóxicas.

Esta foto la pueden usar contra los fachas y los rojipardos como el ajo con los vampiros. Viva la resistencia.

Aquí estarem

that moment when your response to fucking referee two already resembles a bibliographic review paper.

Honestly, we’ve had enough of political scientists dismissing structural polarization as a valid measure of polarization. Theoretical foundations? Solid. Empirical evidence? Abundant. Time to stop gatekeeping and protecting your little academic turf. Enough is enough.

Question for the statistical physicists in the room: What is the difference between thermodynamic temperature and temperature in statistical mechanics? And what aspect of the material world ensures they are the same?
