Opinions within Media, Power and Gossip
Walter Quattrociocchi, Rosaria Conte, Elena Lodi

TL;DR
This paper develops a socio-cognitive model to analyze how different sources and perceptions of information influence opinion formation and societal dynamics, using simulations based on Italian political campaign data.
Contribution
It introduces a novel computational model of opinion dynamics incorporating multiple information sources and cognitive mechanisms, validated through scenario simulations.
Findings
Different information sources impact opinion formation.
Perceived reliability influences acceptance of information.
Simulations reveal conditions leading to societal consensus or polarization.
Abstract
Despite the increasing diffusion of the Internet technology, TV remains the principal medium of communication. People's perceptions, knowledge, beliefs and opinions about matter of facts get (in)formed through the information reported on by the mass-media. However, a single source of information (and consensus) could be a potential cause of anomalies in the structure and evolution of a society. Hence, as the information available (and the way it is reported) is fundamental for our perceptions and opinions, the definition of conditions allowing for a good information to be disseminated is a pressing challenge. In this paper starting from a report on the last Italian political campaign in 2008, we derive a socio-cognitive computational model of opinion dynamics where agents get informed by different sources of information. Then, a what-if analysis, performed trough simulations on the…
