The malpractice of “rationality” in international relations

Abstract

This article investigates the misuse of "rationality" in academic and political discourses, focusing on the Iranian nuclear project. The concept of rationality is ubiquitous; scholars, pundits, and practitioners turn to it, sometimes unwittingly, to describe, explain, and predict. When concerning concrete security and foreign policies, however, this praxis borders on malpractice: rationality-based descriptions are largely either false or unfalsifiable; many observers fail to explicate the meaning of "rationality" they employ; and the concept is frequently used politically to distinguish between "us and them." Empirically, I show that rationality has played an opaque and excessive role in the Western accounts of Iranian nuclear policy. Both "optimists" and "pessimists" have frequently, but faultily, turned to rationality/irrationality to explain Iran's moderate/belligerent nuclear policy and its susceptibility/resistance to nuclear deterrence. The malpractice of "rationality" in discussing such matters has become a bad habit, which is best uprooted.
