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...

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: ow.ly/hLrY50Y3KPk

New system states introduced with the parameter μ. The same parameterization except for different innovation probability μ can lead to consensus in a homogeneous topology or two polarized communities. On the left, the innovation probability μ = 1. On the right, μ = 0.1.

New paper out, “Edge-based reputation promotes cooperation in simplicial complexes,” (arxiv.org/abs/2511.22234). Here, we take a step forward by introducing a new reputation mechanism that operates in group contexts, not just pairwise ones. (1/4)

Now out: "Directionality-induced jamming in multiplex networks" (arxiv.org/abs/2510.22634). We uncover a previously unreported diffusion regime, termed directionality-induced jamming, in multiplex networks that arises solely from the directionality of interlayer couplings. (1/4)

Last of 2024: "Interplay of epidemic spreading and vaccine uptake under complex social contagion"(arxiv.org/abs/2412.11766). Here we investigate the interaction between disease dynamics (simple contagion), and human behavior in vaccine uptake (complex contagion). Results show a rich phase space.

Now out: "Contagion dynamics on higher-order networks" (arxiv.org/abs/2402.14938). This is a focused review of the topic that also proposes a unified formalism covering most of the functional forms used for the spreading dynamics and discusses a roadmap for empirical validation.
