Jia et al. experimentally show that when individuals can tailor their actions to each neighbour - a freedom termed social networking agency - they display higher cooperation, trust and fairness in economic games. @ivanromic.bsky.social @pholme.bsky.social www.nature.com/articles/s41...

New paper in NHB 📄🚨 We ran extensive experiments to show that making the rules of some canonical economic games looser, makes people more cooperative www.nature.com/articles/s41...
