My background




Welcome to Barry O'Neill's website 4

I study decision-making in social contexts.  My main work uses game theory to study the prevention of war.  My approach views the international system as a society, and considers honour, prestige, face, norms, et al.

A more general topic is mediation, negotiation, fairness and conflict resolution. I'm also interested the basics of game theory, to extend it to new problems and apply it more effectively.

I also study long-repeated myths about public policy, to understand how they arise and spread.

I'm a professor in the Political Science Department at UCLA, where I teach courses on international negotiation and mediation, game theory, and the political aspects of nuclear weapons.
