Valerio Capraro

Senior Lecturer


The conflict between cooperation and self-interest is one of the most important conflicts in human decision making. Self-interest is individually optimal, but may lead to war and destruction; cooperation leads to peaceful, healthy, and ultimately more successful societies, but it requires individuals to pay a cost for the benefit of others. I combine behavioral experiments, mathematical modelling, and numerical simulations to understand how people solve this and related conflicts, with the goal of helping institutions to create more collaborative societies.
