Bio

Bear F. Braumoeller is a computational social scientist who studies international order and international conflict. He is the founder and director of the MESO Lab, a social science research lab dedicated to exploring the relationship between international order and international conflict. His most recent book, Only the Dead: The Persistence of War in the Modern Age (Oxford, 2019), evaluates the empirical support for the decline-of-war thesis advocated by scholars like Steven Pinker and argues that patterns of international order are better predictors of trends in warfare than the spread of empathy, morality, and reason. His current research combines theoretical, statistical, and case-study methods to explore the relationship between international order and international conflict. He is a Fellow of the American Association for the Advancement of Science, holder of the Baronov and Timashev Chair in Data Analytics, and Faculty Co-Lead of the Computational Social Science Community of Practice at the Translational Data Analytics Institute at The Ohio State University, where he serves as Professor in the Department of Political Science.

What I Do

I am a computational social scientist. In my case, that means that I use statistics, computational methods, and historical research to explore the causes and consequences of war, develop new social-science models, and understand international order.

International Conflict

Is war going out of style? When do Great Powers compete for influence in the international system, and how does their competition produce war?

Theoretical Models

How can social science domain knowledge best be captured in statistical, dynamic, strategic, networked, and agent-based theoretical models?

International Order

Why are people so extraordinarily cooperative? What drives collective action for the common good? How is order related to war?

Awards and Honors

I am a Fellow of the American Association for the Advancement of Science, and in 2016 I was a visiting fellow at the Norwegian Nobel Institute, where I took part in a Nobel Symposium on the causes of peace. I’ve also been honored to present my research at the National Academies of Sciences, Engineering, and Medicine.

MESO Lab

I am fortunate to have a group of brilliant collaborators in the MESO Lab (for Modeling Emergent Social Order), whose work has been funded by the National Science Foundation, the Carnegie Corporation of New York, the Mershon Center for International Security Studies, and the Department of Political Science at Ohio State.
