Cooperation and assortativity with dynamic partner updating
"[...] we report on a series of human subjects experiments in which groups of 24 participants played an iterated prisoner’s dilemma game where, critically, they were also allowed to propose and delete links to players of their own choosing at some variable rate. [...] we found that cooperators did punish defectors by severing ties, leading to higher levels of cooperation that persisted for longer." Full paper @ PNAS
