Neorealism, neoclassical realism and the problem(s) of history

Abstract

Following scholarship on IR’s ‘historical turn’ as well as on neorealism and neoclassical realism, this article finds fault particularly in neorealism’s implicit reliance on the historically contingent but incompletely conceptualised transmission of systemic factors into state behaviour. Instead, it suggests that neoclassical realism (NCR) is well-suited to leveraging ‘history’ in systematic and general explanation. This article interrogates two routes towards a historically sensitive NCR (intervening variables and structural modifiers), and how they enable different operationalisations of ‘history’ as a sequence of events, cognitive tool or collective narrative. The first route suggests history underpins concepts and variables currently used by neoclassical realists. Here, history is more easily operationalised and allows a clearer view at learning and emulation processes. It is also more clearly scoped, and therefore less ‘costly’ in terms of paradigmatic distinctiveness. The second route, in which history modifies structural incentives and constraints, is more theoretically challenging especially in terms of differentiating NCR from constructivist approaches, but lends itself to theorising systemic change. Both routes provide fruitful avenues for realist theorising, can serve to emancipate NCR from neorealism in IR and foster cross-paradigmatic dialog. Examining how ‘history’ can be leveraged in realism allows interrogating how other ‘mainstream’, positivist approaches can and should leverage historical contingency, context and evidence to explain international processes and outcomes.
