Vasopressin increases human risky cooperative behavior.

ABSTRACT: The history of humankind is an epic of cooperation, which is ubiquitous across societies and increasing in scale.

Here we show that arginine vasopressin (AVP), a neuropeptide that mediates complex mammalian social behaviors such as pair bonding, social recognition and aggression causally increases humans' willingness to engage in risky, mutually beneficial cooperation.
