几个狂热分子能影响一个社会大部分人的意见吗?

Can a few fanatics influence the opinion of a large segment of a society?

Dietrich Stauffer, Muhammad Sahimi

摘要:

模型,提供洞察如何极端的立场,任何社会现象可能会在一个社会或在全球范围内传播的当前极大的兴趣。一个现实的模型必须考虑到这样一个事实,即全球化和互联网已经产生了人与人之间的无尺度互动网络。我们提出了一个新的模型,它考虑到了互动网络的性质,并提供了一些关键的见解,这一现象,包括:(1)有一个层次网络之间的根本区别,即人们受到那些在层次上更高,但不是由那些低于他们,和一个对称的网络,人对人的影响相互作用。(2)少数“狂热分子”可以暂时(在等级网络中)或永久(在对称网络中)影响大部分人口。即使“狂热分子”消失了,民众仍可能容易受到他们所主张的立场的影响。然而,这一模式具有普遍性,适用于人口中有一定程度热情或易感性的任何现象。

英文摘要:

Models that provide insight into how extreme positions regarding any social phenomenon may spread in a society or at the global scale are of great current interest. A realistic model must account for the fact that globalization and internet have given rise to scale-free networks of interactions between people. We propose a novel model which takes into account the nature of the interactions network, and provides some key insights into this phenomenon, including: (1) There is a fundamental difference between a hierarchical network whereby people are influenced by those that are higher on the hierarchy but not by those below them, and a symmetrical network where person-on-person influence works mutually. (2) A few "fanatics" can influence a large fraction of the population either temporarily (in the hierarchical networks) or permanently (in symmetrical networks). Even if the "fanatics" disappear, the population may still remain susceptible to the positions advocated by them. The model is, however, general and applicable to any phenomenon for which there is a degree of enthusiasm or susceptibility to in the population.
