The Dynamics of Polarization
In social psychology, the concept of "group polarization" identifies the process by which a certain attitude or opinion tends to become more radical within a community after being debated.
If the evidence of this type of phenomenon is incontrovertible, its mechanisms are largely still to be clarified and are subject to interdisciplinary analysis.
I will review the most influential theories explaining polarization phenomena, focusing in particular on the one that identifies the circulation of "new and persuasive arguments" as the main driver of this type of process.
I will then illustrate some open research questions and point to others that can be rigorously addressed through the tools provided by linguistic analysis, formal argumentation and knowledge representation.
Carlo Proietti
Carlo ProiettiHe is currently a Researcher at the Institute for Computational Linguistics "A. Zampolli" of the National Research Council of Italy.
He comes from Concordia Sagittaria (VE) and studied philosophy at the University of Pisa as a student of the Scuola Normale Superiore of Pisa.
He received his PhD from the University of Paris I Panthéon-Sorbonne, in co-supervision with the University of Pisa, with a thesis on logic on the problem of future contingents and the paradox of knowability.
He was a PostDoc and then a Researcher at the University of Lund and, more recently, a Marie Curie Fellow at the Institute for Logic, Language and Computation of the University of Amsterdam.
He deals with argumentation theory, logic and epistemology.
Specifically, his research focuses on the application of formal methods of these disciplines to the analysis of information exchange processes within groups, with a particular interest in the dynamics that generate undesirable effects such as information cascades, echo chambers and polarization of opinions.
