TL;DR: In this paper, a simple Ising spin model is proposed to describe a mechanism of making a decision in a closed community and it is shown via standard Monte Carlo simulations that very simple rules lead to rather complicated dynamics and to a power law in the decision time distribution.

Abstract: A simple Ising spin model which can describe a mechanism of making a decision in a closed community is proposed. It is shown via standard Monte Carlo simulations that very simple rules lead to rather complicated dynamics and to a power law in the decision time distribution. It is found that a closed community has to evolve either to a dictatorship or a stalemate state (inability to take any common decision). A common decision can be taken in a "democratic way" only by an open community.

TL;DR: In this paper, the authors propose a model to simulate the process of opinion formation in a society where the traditional division into leftists and rightists is not enough any longer, based on the Ashkin-Teller idea to assign two Ising spins to each site (agent).
