社会制度缺乏共识

Lack of consensus in social systems

I. J. Benczik, S. Z. Benczik, B. Schmittmann, R. K. P. Zia

摘要:

我们提出了一个完全可解的模型,在两党制的选民的动态。意见形成过程是一个随机网络的代理人。人际关系的动态本质也反映在模型中,因为网络中的联系随着选民的动态而演变。在无限的时间限制,一个精确的解决方案预测出现的共识,任意的初始条件。然而,在达成共识之前,两种不同的亚稳态可以持续指数级长的时间。一种状态反映了意见的完美平衡,另一种状态反映了完全静止的情况。对相关寿命的估计表明,缺乏共识是大型系统的典型特征。

英文摘要:

We propose an exactly solvable model for the dynamics of voters in a two-party system. The opinion formation process is modeled on a random network of agents. The dynamical nature of interpersonal relations is also reflected in the model, as the connections in the network evolve with the dynamics of the voters. In the infinite time limit, an exact solution predicts the emergence of consensus, for arbitrary initial conditions. However, before consensus is reached, two different metastable states can persist for exponentially long times. One state reflects a perfect balancing of opinions, the other reflects a completely static situation. An estimate of the associated lifetimes suggests that lack of consensus is typical for large systems.
