This chapter describes the majority judgment method used to elect officials; to classify wines; and to judge Olympic competitors in skating, diving, and gymnastics. It also provides ways to counteract cheating and strategic manipulation of the judges or the voters. The desirable properties of classical social choice theory are satisfied by the majority judgment method. The chapter also explains several key ideas, including majority-grade, majority-ranking, majority-value, majority-gauge, abbreviated majority-value, and kth-order function. It demonstrates the superiority of the majority judgment to any other method of voting and judging competitions by comparing the basic principles of the traditional theory of social choice.
