How the cohesion of a social network is being maintained in spite of having different layers of social interaction is an important question. I argue that the evolution of both (political) hierarchy and social identity play a crucial role in scaling up and bonding social networks. Together they are missing links in the social brain hypothesis, and further research is needed to understand the functions of leadership and social identity.
尽管存在不同层次的社会互动，但社会网络的凝聚力是如何维持的，这是一个重要的问题。我认为，（政治）等级制度和社会认同的演变在扩大和加强社会网络方面起着至关重要的作用。它们共同构成了社会大脑假说中的缺失环节，需要进一步研究来理解领导力和社会认同的功能。
