Persuasion in Politics
构建了一个通过讨论和相互说服形成社会网络（如政党、工会）的模型，网络形成后可被政治家租用以争取选票，导致政党纲领不向中间选民收敛，而是分离信息并隔离成员。
We present a model of the creation of social networks, such as political parties, trade unions, religious coalitions, or political action committees, through discussion and mutual persuasion among their members. The key idea is that people are influenced by those inside their network, but not by those outside. Once created, networks can be “rented out” to politicians who seek votes and support for their initiatives and ideas, which may have little to do with network members' core beliefs. In this framework, political competition does not lead to convergence of party platforms to the views of the median voter. Rather, parties separate their messages and try to isolate their members to prevent personal influence from those in the opposition.
