Il CREF promuove linee di ricerca originali e di grande impatto, improntate ai metodi della fisica, ma con un forte carattere interdisciplinare e in relazione con i principali problemi della moderna società della conoscenza.
CREF nasce con la duplice anima di Centro di Ricerca e di Museo Storico, con l’intento di conservare e diffondere la memoria di Enrico Fermi, oltre che favorire un’ampia diffusione e comunicazione della cultura scientifica.
In mid-January 2021, an unprecedented event took place: users of an online Reddit community called r/wallstreetbets could play a primary role in orchestrating the short squeeze of GameStop shares. This event represents a paramount example of collective coordination action on social media, resulting in large-scale consensus formation and significant market impact. In this work, researchers Anna Mancini, Antonio Desiderio, Riccardo Di Clemente, and Giulio Cimini characterize the structure and time evolution of Reddit conversation data, showing that the occurrence and sentiment of GME-related comments increased significantly before the short squeeze.
Starting from a hypothesis of peer imitation to qualitatively describe the phenomenon observed, they introduce a model of opinion formation simulating a situation where first neighbours and the global state of the community influence an individual’s opinion. This work provides insight into some of the key features of online processes concerning large-scale consensus formation.
