Abstract: This paper introduces the "Culling Hypothesis," a model for understanding the rise and fall of nations' martial capacities. It posits that major wars act as a powerful selective pressure, disproportionately culling individuals possessing a "warrior archetype" profile (characterized by high aggression and low empathy). The hypothesis argues that this archetype is not essential for warfare but acts as a powerful accelerator, increasing a nation's capacity, efficiency, and probability of waging war. The demographic reduction of this archetype through conflict leads to two primary consequences: a diminished geopolitical capacity for external power projection and a more docile, governable domestic population (the "Governability Corollary"). Through comparative case studies of Post-WWII Germany, Japan, the USSR, France, and the United States, the paper demonstrates how this demographic mechanism, in a "tug-of-war" with cultural forces, provides a powerful and overlooked explanation for the long-term trajectories of nations. Finally, the paper extends this model to explain the recalcitrance of modern non-state actors, arguing that they represent a purified concentration of this very archetype.
