International Norms as Emergent Properties of Complex Adaptive Systems

Abstract

Abstract This theory note argues that international norms, as currently understood by scholars of international relations, can be seen as emergent properties of a complex adaptive system (the international political system). Arising from the microlevel interactions of agents within and across various levels of analysis, they have the potential to become system properties that (a) influence the constitution, relationships, and behavior of agents within that system and (b) are not analytically reducible to the sum of the interactions between those agents. They also exhibit evolutionary dynamics common to complex, rather than merely complicated, systems. Thinking of norms in this manner helps point norms scholars toward particular spaces and methodologies of research. After a brief resume of complexity theory in IR, the note proceeds with an introduction to complex systems theory. It then explores the conceptual nexus between norms theory and complexity. It finishes by suggesting the ways in which understanding norms as complex emergent phenomena might influence norms research more broadly.
