Beyond the Wisdom of the Crowd: How Network Topology Distorts Collective Perception
Giovanni Palermo, Vittorio Loreto, Giulio Cimini
Cognitive biases are often attributed to heuristics or limited information. Yet the structure of social networks is a key, often-overlooked source of perceptual bias. When informat…
Polarization and echo chambers in Reddit's political discourse
Daniele Cirulli, Antonio Desiderio, Giulio Cimini +1
Political debate nowadays takes place mainly on online social media, with election periods amplifying ideological engagement. Reddit is generally considered more resistant to polar…
Geometric Criticality in Scale-Invariant Networks
Lorenzo Lucarini, Giulio Cimini, Pablo Villegas
Dimension in physical systems determines universal properties at criticality. Yet, the impact of structural perturbations on dimensionality remains largely unexplored. Here, we cha…
How Large Language Models play humans in online conversations: a simulated study of the 2016 US politics on Reddit
Daniele Cirulli, Giulio Cimini, Giovanni Palermo
Large Language Models (LLMs) have recently emerged as powerful tools for natural language generation, with applications spanning from content creation to social simulations. Their…
Evolution and determinants of firm-level systemic risk in local production networks
Anna Mancini, Balázs Lengyel, Riccardo Di Clemente +1
Recent crises like the Covid-19 pandemic and geopolitical tensions have exposed vulnerabilities and caused disruptions of supply chains, leading to product shortages, increased cos…
Maximum entropy modeling of Optimal Transport: the sub-optimality regime and the transition from dense to sparse networks
Lorenzo Buffa, Dario Mazzilli, Riccardo Piombo +3
We present a bipartite network model that captures intermediate stages of optimization by blending the Maximum Entropy approach with Optimal Transport. In this framework, the netwo…
