Mathematical Programming for the Dynamics of Opinion Diffusion [PDF]

Physics, 2023
The focus of this paper is on analyzing the role and the choice of parameters in sociophysics diffusion models by leveraging the potentialities of sociophysics from a mathematical programming perspective. We first present a generalised version of Galam’s

A Model for the Formation of Beliefs and Social Norms Based on the Satisfaction Problem (SAT) [PDF]

Entropy
We propose a numerical representation of beliefs in social systems based on the so-called SAT problem in computer science. The main idea is that a belief system is a set of true/false values associated with claims or propositions. Each individual assigns

Unanimity, Coexistence, and Rigidity: Three Sides of Polarization [PDF]

Entropy, 2023
Political polarization is perceived as a threat to democracies. Using the Galam model of opinion dynamics deployed in a five-dimensional parameter space, I show that polarization is the byproduct of an essential hallmark of a vibrant democratic society ...

A Biased Review of Sociophysics [PDF]

Journal of Statistical Physics, 2012
Various aspects of recent sociophysics research are shortly reviewed: Schelling model as an example for lack of interdisciplinary cooperation, opinion dynamics, combat, and citation statistics as an example for strong interdisciplinarity.

Sociophysics: a personal testimony [PDF]

Physica A: Statistical Mechanics and Its Applications, 2004
The origins of Sociophysics are discussed from a personal testimony. I trace back its history to the late seventies. My twenty years of activities and research to establish and promote the field are reviewed. In particular the conflicting nature of Sociophysics with the physics community is revealed from my own experience.

The Trump phenomenon: An explanation from sociophysics [PDF]

International Journal of Modern Physics B, 2017
The Trump phenomenon is argued to depart from current populist rise in Europe. According to a model of opinion dynamics from sociophysics the machinery of Trump’s amazing success obeys well-defined counter-intuitive rules. Therefore, his success was in principle predictable from the start.

Hybrid Galam–Bass Model for Technology Innovation [PDF]

Entropy
This work proposes a hybrid model that combines the Galam model of opinion dynamics with the Bass diffusion model used in technology adoption on Barabasi–Albert complex networks.

Ratio-Dependent Contrarian Activation in Opinion Dynamics [PDF]

Entropy
I study the impact of mixed contrarians on the opinion dynamics of a heterogenous population with conformists using the Galam Majority Model. Activation of contrarians is a function of the majority/minority ratio in the local groups of discussion ...

Conformity and Mass Media Influence in the Sznajd Model on Regular Lattices [PDF]

Entropy
The polarization of opinions and difficulties in reaching a consensus are central problems of many modern societies. Understanding the dynamics governing those processes is, therefore, one of the main aims of sociophysics.
