International relations theory long relied on classical mechanistic physics, treating sovereign nations as hard, billiard-ball states bouncing off each other; quantum social theory models global politics as an entangled, non-local web of shared consciousness and identity.

For centuries, realism and liberalism in international relations borrowed their mental models from Newtonian mechanics: nation-states are independent, self-contained entities with fixed interests, colliding like billiard balls on a geopolitical table.
This classical reductionism fails to explain modern global crises—nuclear deterrence psychology, ideological contagion, viral misinformation, and collective climate paralysis—where human consciousness, emotion, and identity are deeply entangled across borders.
Published in International Studies Review, this theoretical paper bridges quantum social theory with international politics. Drawing on Alexander Wendt's quantum paradigm, the author demonstrates that diplomatic relations and global governance exhibit quantum-like properties: wave-particle duality of state identity, non-local institutional entanglement, and observer effects in treaty negotiations.
Adopting a quantum social lens transforms international diplomacy, moving beyond zero-sum military balances toward holism, mutual empathy, and cooperative global conflict de-escalation in an interconnected world.
International Relations, Quantum Social Theory, and Scientific Reductionism
Alex Wendt’s Quantum Mind and IR has sparked a new debate among scholars of international relations about the nature of the objects studied. Wendt points out that other disciplines’ adoption of a quantum framework has enabled them to gain explanatory power. He describes two assumptions that he admits are far from obvious but defends them by detailing the significant intellectual gains and explanatory power they add. Wendt thus argues for the quantum framework by means of an intellectual cost-benefit calculation. Quantum Mind details the benefits but attends less to the costs; the latter are the focus of this paper.
