Spontaneous Symmetry Breaking, Group Decision Making and Beyond 2. Distorted Polarization and Vulnerability
Serge Galam
This paper extends previous work on echo chambers modeled by an Ising-like system at zero temperature (1. Echo Chambers and random Polarization, Symmetry 2024, 16(12), 1566). There…
Ambiguities, Built-in Biases and Flaws in Big Data Insight Extraction
Serge Galam
I address the challenge of extracting reliable insights from large datasets using a simplified model that illustrates how hierarchical classification can distort outcomes. The mode…
Democratic Thwarting of Majority Rule in opinion dynamics: 1. Unavowed Prejudices versus Contrarians
Serge Galam
I study the conditions under which a democratic dynamics of a public debate drives a Minority-to-Majority transition. A landscape of the opinion dynamics is thus built using the Ga…
Spontaneous Symmetry Breaking, Group Decision Making and Beyond 1. Echo Chambers and Random Polarization
Serge Galam
Starting from a symmetrical multiple choice individual I build a sociophysics model of decision making. Reducing the choices to two and interactions to pairs recover the Ising mode…
