Political advocacy groups 开始使用information services散布information，因为 many groups 因此可以超越传统资源直接发布政论，information services 因此展现了个比以往更和谐，更立体的画面 

假设： Information on political issues disseminated through information services does not come almost entirely from advocacy groups that share a single bias。争论来自不同群体，没有被某种偏见垄断。
