直接和间接的社会影响-同伴压力（PP）-对社会群体的集体决策有什么影响？我们提出了一个模型，捕捉PP作为一个社会群体中的个人之间的社会文化距离的函数。使用这个模型和来自15个真实世界社交网络的经验数据，我们发现PP水平决定了一个社会群体达成共识的速度。更重要的是，人民党的水平决定了领导者谁能够实现对社会群体的全面控制。人民党可以克服与地方领导人联系紧密的社区或意见凝聚力差的领导人对共识造成的障碍。适度的生产力水平也是解释创新在各种社会群体中扩散的速度所必需的。
What is the effect of the combined direct and indirect social influences—peer pressure (PP)—on a social group's collective decisions? We present a model that captures PP as a function of the socio-cultural distance between individuals in a social group. Using this model and empirical data from 15 real-world social networks we found that the PP level determines how fast a social group reaches consensus. More importantly, the levels of PP determine the leaders who can achieve full control of their social groups. PP can overcome barriers imposed upon a consensus by the existence of tightly connected communities with local leaders or the existence of leaders with poor cohesiveness of opinions. A moderate level of PP is also necessary to explain the rate at which innovations diffuse through a variety of social groups.
