The Luck of the Draw

A prominent scholar once noted that lotteries in politics and society-to break vote ties, assign students to schools, draft people into the military, select juries-are "at first thought absurd, and at second thought obvious." Lotteries have been part of politics since the Greek and Roman times, and they are used frequently in American politics today. When there is a two-to-two vote tie for prospective school board members, officials will often resort to flipping acoin (as happened recently in California). And in military drafts, the conventional wisdom is that random selection is far more just than non-lottery drafts. Northerners rioted against the perceived injustice of the non-random draft during the Civil War, and Americans by and large believed thatstudent deferments subverted the justice of the draft during the Vietnam War. Over the years, people who study and practice politics have devoted considerable effort to thinking about the legitimacy of lotteries and whether they are just or not under certain circumstances. Yet they have really only focused on lotteries on a case-by-case basis, and no one has ever developed a substantial and comprehensive political theory of lotteries. In The Luck of the Draw, Peter Stone does just that. Examining the wide range of arguments for and against lotteries, Stone comesto the startling conclusion that lotteries have only one crucial effect relevant to decision-making: they have the "sanitizing effect" of preventing decisions from being made on the basis of reasons. Stone readily admits that this rationale might sound absurd to us, but contends that in many instances it isvital for people to make decisions without any reasoned rationale to compel them. Sometimes, justice can only be carried out through random selection-a fundamental principle of the practice of lottery that Stone comes to call "The Just Lottery Rule." By developing innovative ways for interpreting this pervasive form of political practice, Stone provides us with a foundation for understanding how to best make use of lottery when making political decisions both large and small.
