Recent evidence emphasizes pro-social behavior more than conflictuous behavior and thus gradually shifts the explanandum from why cooperation occurs to why cooperation breaks down. Being a basal configuration of social life, we should continue working on developing a better understanding of how individual decision making, social mechanisms and social organization are working together in bringing about social conflict. To this goal a multiagent research program contributes significantly, where agents can be equipped with rich cognitive architectures and empirically informed microbehavior; relationships between the micro and the macro can be made expressive; and socio-cognitive macropatterns can be generated. The talk will draw on many of these issues theoretically and by means of example. There will be a special emphasis on evidence-driven and stakeholder oriented modeling and simulation of social conflict. Short Bio (by himself): I am a Computational Social Scientist at Scensei. Before that I was a Computational Social Scientist at Group W, and a Research Assistant Professor at the Department of Computational Social Science and a Research Fellow at the Krasnow Institute for Advanced Study, both at George Mason University, where I was the PI of a project on studying irregular warfare using multiagent simulation. I have a doctoral degree in political science from the University of Zurich. My particular background is in conflict research and multiagent social simulation. I came to George Mason University in early 2009 after a two-year postdoctoral fellowship at the Centre for Policy Modelling in Manchester, UK. Before that I worked as a doctoral researcher at the Swiss Military Academy at the Swiss Federal Institute of Technology and as a teaching assistant at the University of Zurich. I closely collaborate with Maciek £atek. My view of the world is multiagent: Actors interact with each other in manifold contexts; from running to fighting to parenting. I am trained in political science and computational social science, so I am interested in analyzing and understanding the cultural, political and social dimension of context behaviors; how people and organizations make decisions and how they shape their environment. To do so I apply data collection, data analysis, and social simulation techniques, including participatory experiments, semantic concept mapping and multiagent modeling. I work both academically and provide commercial services at Scensei, an analytics enterprise. Our clients at Scensei use our services to improve their own analytics and to make more effective and sustainable decisions in complex adaptive environments.
