Why It Is Not Unreasonable to Fear Terrorism

Abstract

A common view has it that since we are far likelier to be killed in some road or household accident than in a terror attack, our fear of the latter is exaggerated. I argue that terrorism's relatively limited death toll need not mean that fearing it is unreasonable, nor does it immediately imply that counter-terrorism policies are unjustified – whatever other, legitimate concerns these policies give rise to. First, I argue that in the special case of terrorism, it is misleading to focus on risk per capita, as critics typically do. Second, while terrorism has a probabilistic component which should be relevant to decision-making, risk is not entirely or even primarily what terrorism is all about. Third, I argue that fearing terrorism may be reasonable even while recognizing the small probability of personal harm. Due to terrorism's random character, the belief that one will escape harm rests on little more than statistical evidence. As I explain, this leaves some room for reasonable doubt, and a justified level of fear.
