In her response to our article, Mette Eilstrup-Sangiovanni replaces balance-of-power theory (threat of hegemony begets balancing, which produces a tendency of international systems toward equilibria of power) with a complex congeries of competing and contingent conjectures about when states might balance. While these are certainly part of the extensive literature on the balance of power, lumping them together and calling them a `theory' invites a comedy of errors rather than an empirical test. The `ado' in our article was a novel empirical test of a theory that has been central to centuries of IR theorizing. As our review of the evidence confirms, this theory can indeed be evaluated in ancient and non-European international systems, and it is wrong: international systems do not tend toward equilibria of power, and balancing is relatively unimportant in explaining the equilibria that do occur. We end up agreeing with the gist of Sangiovanni's response: there is no empirically valid systemic balance-of-power theory, and it is time to turn to contingent middle-range hypotheses about balancing behavior.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
