Partner Selection Shapes the Strategic and Topological Evolution of Cooperation
Coevolution of individual strategies and social ties, in which individuals not only adjust their strategies by social learning but also switch their adverse partners to search for potential beneficial ones, has attracted increasing attention very recently. It is found that the interplay of strategic updating and partner network adaptation can facilitate the escape from the stalemate of cooperat...
متن کاملPartner Choice in Raven (Corvus corax) Cooperation
Although social animals frequently make decisions about when or with whom to cooperate, little is known about the underlying mechanisms of partner choice. Most previous studies compared different dyads' performances, though did not allow an actual choice among partners. We tested eleven ravens, Corvus corax, in triads, giving them first the choice to cooperate with either a highly familiar or a...

Policy actors seek network contacts to mitigate collective action problems endemic in all policy arenas. The Risk Hypothesis argues that actors seek contacts that maximize information transmission when cooperation involves low risks, but seek transitive, reciprocal relationships when risks of defection increase. We apply this risk hypothesis to 10 estuaries in the U.S, using survey data from 19...
متن کاملPartner selection supports reputation-based cooperation in a Public Goods Game
In dyadic models of indirect reciprocity, the receivers’ history of giving has a significant impact on the donor’s decision. When the interaction involves more than two agents things become more complicated, and in large groups cooperation can hardly emerge. In this work we use a Public Goods Game to investigate whether publicly available reputation scores may support the evolution of cooperati...

The natural tendency for humans to make and break relationships is thought to facilitate the emergence of cooperation. In particular, allowing conditional cooperators to choose with whom they interact is believed to reinforce the rewards accruing to mutual cooperation while simultaneously excluding defectors. Here we report on a series of human subjects experiments in which groups of 24 partici...
