Objective

Throughout history, what has been causing tremendous suffering is groups of people fighting each other. While behavioral science research has advanced our understanding of such intergroup conflict, it has exclusively focused on micro-level processes within and between groups at conflict. Disciplines that employ a more historical perspective like climate studies or political geography report that macro-level pressures due to changes in climate or economic scarcity can go along with social unrest and wars. How do these macro-level pressures relate to micro-level processes? Do they both occur independently, or do macro-level pressures trigger micro-level processes that cause intergroup conflict? And if so, which micro-level processes are triggered, and how?

With unavoidable signs of climate change and increasing resource scarcities, answers to these questions are urgently needed. Here I propose carrying-capacity stress (CCS) as the missing link between macro-level pressures and micro-level processes. A group experiences CCS when its resources do not suffice to maintain its functionality. CCS is a function of macro-level pressures and creates intergroup conflict because it impacts micro-level motivation to contribute to one’s group’s fighting capacity and shapes the coordination of individual contributions to out-group aggression through emergent norms, communication and leadership.

To test these propositions I develop a parametric model of CCS that is amenable to measurement and experimentation, and use techniques used in my work on conflict and cooperation: Meta-analyses and time-series analysis of macro-level historical data; experiments on intergroup conflict; and measurement of neuro-hormonal correlates of cooperation and conflict. In combination, this project provides novel multi-level conflict theory that integrates macro-level discoveries in climate research and political geography with micro-level processes uncovered in the biobehavioral sciences
