How Not to Evaluate Theories

Abstract

The recent decline in the United States' economic fortunes does not vindicate any prediction made by any balance-of-power realist, has no implications for any theoretical proposition about the functioning of a unipolar system, and has not caused a structural shift to bi- or multipolarity. Things can be made to seem otherwise only when scholars use inconsistent measures of capabilities, do not define terms with precision, forward inherently unfalsifiable arguments, and fail to clarify causal mechanisms. © 2012 International Studies Association.
