 \n\nHow to stop the emergence of segregation in cooperative networks\n\nDav
 id Melamed\, The Ohio State University\n\nAbstract: Cooperation among anima
 ls is a paradox because individuals are better off not cooperating with oth
 ers. One prevalent explanation for the high levels of cooperation we observ
 e among humans is the effect of the network structures in which we are embe
 dded. Clustering structurally insulates cooperators\, enabling high rates o
 f cooperation within network communities or clusters. At the same time\, we
  know that networks are clustered by demographic attributes. Taken together
 \, the result is demographically similar clusters with high rates of cooper
 ation. That is\, these two processes generate the emergence of cooperative 
 but segregated clusters. Here we present two studies on these processes. St
 udy 1 documents the results described above\, and study two systematically 
 varies types of reputations. We find that we can eliminate the emergence of
  segregation by altering the types of reputations that are used in the netw
 orks. I conclude with a discussion of reducing segregation in polarized con
 texts.
