SOCIOPHYSICS: A REVIEW OF GALAM MODELS
  • S. Galam
  • Political Science, Computer Science
  • 12 March 2008
TLDR
Using a series of models of sociophysics introduced by Galam and Galam et al. several major real political events were successfully predicted including the victory of the French extreme right party in the 2000 first round of French presidential elections, the voting at fifty–fifty in several democratic countries, and the defeat of the "no" to the 2005 French referendum on the European constitution.
Minority opinion spreading in random geometry
Abstract:The dynamics of spreading of the minority opinion in public debates (a reform proposal, a behavior change, a military retaliation) is studied using a diffusion reaction model. People move by

Part 1: Sociophysics: setting the frame.- What is sociophysics about?.- The question: do humans behave like atoms?.- Sociophysics: the origins.- Sociophysics: weaknesses, achievements and
Modelling rumors: the no plane Pentagon French hoax case

  • 25 November 2002
Abstract The recent astonishing wide adhesion of French people to the rumor claiming ‘No plane did crash on the Pentagon on September 11’, is given a generic explanation in terms of a model of
Sociophysics: A new approach of sociological collective behaviour. I. mean‐behaviour description of a strike
A new approach to the understanding of sociological collective behaviour, based on the framework of critical phenomena in physics, is presented. The first step consists of constructing a simple
Contrarian deterministic effects on opinion dynamics: “the hung elections scenario”
  • S. Galam
  • Mathematics, Physics
  • 16 July 2003
We study the effects of contrarians on the dynamics of opinion forming using the 2-state Galam opinion dynamics model. In a single update step, groups of a given size are defined and all agents in
Towards a theory of collective phenomena: Consensus and attitude changes in groups
This study presents the outline of a model for collective phenomena. A symmetry-breaking model combines a number of well-established social psychology hypotheses with recent concepts of statistical
Application of statistical physics to politics
  • S. Galam
  • Mathematics, Physics
  • 1 December 1999
The concept and technics of real space renormalization group are applied to study majority rule voting in hierarchical structures. It is found that democratic voting can lead to totalitarianism by
Sociophysics: a personal testimony
  • S. Galam
  • Sociology, Physics
  • 25 March 2004
The origins of Sociophysics are discussed from a personal testimony. I trace back its history to the late 1970s. My 20 years of activities and research to establish and promote the field are
Square-lattice site percolation at increasing ranges of neighbor bonds.

  • 18 January 2005
TLDR
The existing Galam-Mauger universal formula for percolation thresholds does not reproduce the data showing dimension and coordination number are not sufficient to build a universal law which extends to complex lattices.
