Sociophysics: a new approach of sociological collective behaviour. I. Mean-behaviour description of a strike

TL;DR

This paper introduces a physics-inspired mean-behaviour model to analyze collective behaviour in sociological systems, specifically applying it to model and understand the dynamics of strikes in a plant.

Contribution

It presents a novel sociophysical model that captures phase transitions and metastability in collective behaviour, linking physical critical phenomena to social dynamics.

Findings

Identification of two phases: collective and individual.

Existence of a critical point with high sensitivity to parameters.

Metastability explains irreversibility in strike transitions.

Abstract

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 mean-behaviour model and applying it to a strike process in a plant. The model comprises only a limited number of parameters characteristic of the plant considered and of the society. A dissatisfaction function is introduced with a basic principle stating that the stable state of the plant is a state, which minimizes this function. It is found that the plant can be in one of two phases: the "collective phase" and the "individual phase". These two phases are separated by a critical point, in the neighbourhood of which the system is very sensitive to small changes in the parameters. The collective phase includes a region of parameters for which the system has two possible states: a "work state" and a "strike state". The actual state of the system depends on the parameters and on the "history of the system". The irreversibility of the transition between these two states indicates the existence of metastable states. For these particular states, the effect of small groups of workers or of a small perturbation in the system results in drastic changes in the state of the plant. Other non-trivial implications of the model, as well as possible extensions and refinements of the approach, are discussed.
