Opinion dynamics is an opinion evolution process of a group of agents, where the final
opinion distribution tends to three stable states: consensus, polarization, and fragmentation …

Statistical physics has proven to be a fruitful framework to describe phenomena outside the
realm of traditional physics. Recent years have witnessed an attempt by physicists to study …

Models of continuous opinion dynamics under bounded confidence have been presented
independently by Krause and Hegselmann and by Deffuant et al. in 2000. They have raised …

Polarization is a topic of intense interest among social scientists, but there is significant
disagreement regarding the character of the phenomenon and little understanding of …

We propose a continuous-time multioption nonlinear generalization of classical linear
weighted-average opinion dynamics. Nonlinearity is introduced by saturating opinion …

After an introductory section, this article will focus on four questions: How should the Kyoto
School be defined? What is meant by its central philosophical concept of “absolute …

This paper seeks to make a theoretical and empirical case for the importance of
differentiated identities for group function. Research on groups has found that groups …

We compare patterns of extremism propagation yielded by 4 continuous opinion models,
when the main parameters vary, on different types of networks (total connection, random …

The paper analyzes the chances for the truth to be found and broadly accepted under
conditions of cognitive division of labour combined with a social exchange process …

The book requires only rudimentary physics knowledge but ability to program computers
creatively and to keep the mind open to simple and not so simple models, based in …
