IBSEN has published in Nature interesting results regarding models of the dynamics of social behavior for large groups taking different types of behaviors (the hawk or the dove, aggressive versus cooperative). This will help in the future to develop large human behaviour simulators that will have important consequences like policy testing for pressing societal issues.

The Future and Emerging Technologies-Open  project IBSEN is designed to provide a breakthrough in our understanding of large scale human behaviour. IBSEN is a high-risk project with a high-degree of interdisciplinarity; the team consists of physicists, economists, social psychologists, and computer scientists.

The project's aspiration is to develop a large scale human behavior simulator, a technology providing a basis for socio-economic simulations that would radically change many fields with technological and societal impacts. The project wants to kick start a new way of doing social science for the problems arising in a technologically highly connected society.

In this Nature results paper the project makes inroads to its final goal by generaling  a model of groups behaviour (agressive and cooperative) to any number N of individuals, making it applicable to large groups.

They derive and numerically solve an exact equation for the evolution of the system in both finite and infinite well-mixed populations, finding the conditions for all different types of dynamics including  stable coexistence between both types of group behavior or dominance of one of the groups, depending on a number of controllable parameters.
