Existing research suggesting that humans cooperate if they know more about their own payoffs has been rebutted: In the long run, access to information about payoff distributions leads to less cooperative behavior, finds a recent study in Nature Communications by Steffen Huck, Johannes Leutgeb (both WZB Berlin Social Science Center) and Ryan Oprea (University of California, Santa Barbara). The study also shows that knowledge about earning possibilities leads to smaller earnings in the long-run.
