Topics of Interest:

What determines whether conflict will move in a destructive or constructive direction?

This is the overarching question that has driven decades of research at the ICCCR. While the answers to such questions are complex, we seek to identify the most fundamental factors that lead to qualitative differences in dynamics of conflict and peace.
