意见和社会结构的动态

Dynamics of Opinions and Social Structures

M. Rosvall, K. Sneppen

摘要:

从极端的亚文化到主流的大众文化,音乐品味、政治信念和宗教信仰大相径庭的社会群体层出不穷。基本的社会结构和意见的形成都是动态的,其中一个的变化会影响另一个。已经提出了一些积极的反馈机制,以推动社会和经济制度的多样性,但很少有人致力于查明一个动态变化的社会网络和网络上的信息传播和收集之间的相互作用。在这里,我们分析这种现象的社会网络模型,明确地模拟信息组装和社会结构的出现之间的反馈:不断变化的信念是耦合到不断变化的关系,因为代理自组织的动态网络,以促进他们的狩猎采集行为在信息空间。我们的分析表明,部落组织和模块化的社交网络可以出现作为一个结果,接触寻求代理人,加强他们的信念之间志同道合。我们还发现,有声望的人可以将社会网络简化为围绕自己的等级结构。

英文摘要:

Social groups with widely different music tastes, political convictions, and religious beliefs emerge and disappear on scales from extreme subcultures to mainstream mass-cultures. Both the underlying social structure and the formation of opinions are dynamic and changes in one affect the other. Several positive feedback mechanisms have been proposed to drive the diversity in social and economic systems, but little effort has been devoted to pinpoint the interplay between a dynamically changing social network and the spread and gathering of information on the network. Here we analyze this phenomenon in terms of a social network-model that explicitly simulates the feedback between information assembly and emergence of social structures: changing beliefs are coupled to changing relationships because agents self-organize a dynamic network to facilitate their hunter-gatherer behavior in information space. Our analysis demonstrates that tribal organizations and modular social networks can emerge as a result of contact-seeking agents that reinforce their beliefs among like-minded. We also find that prestigious persons can streamline the social network into hierarchical structures around themselves.
