Introduction
This chapter describes widespread skepticism regarding the value of assessing uncertainty in international politics. “Agnostics” argue that assessments of uncertainty in international politics are too unreliable to be useful for shaping major foreign policy decisions. “Rejectionists” argue that attempting to assess uncertainty in international politics can be counterproductive, surrounding foreign policy analyses with illusions of rigor or exposing foreign policy analysts to excessive criticism. “Cynics” claim that foreign policy analysts and decision makers have self-interested motives to avoid assessing uncertainty. The chapter explains how these ideas lead many scholars, practitioners, and pundits to avoid holding careful debates about the risks surrounding major foreign policy choices. The chapter describes how this aversion to probabilistic reasoning appears in several high-profile cases, such as President Kennedy’s decision to authorize the Bay of Pigs invasion and President Obama’s decision to raid Osama bin Laden’s compound in Abbottabad, Pakistan.
