The traditional theory of social choice offers no good solution to the problems of how to elect, to judge, or to rank. We propose a new and more realistic model where voters evaluate the candidates in a common language of ordinal grades. This small change leads to a new theory and method « majority judgment ». It is at once meaningful, resists strategic manipulation, and is not subject to the paradoxes encountered in practice, notably Condorcet’s and Arrow’s. We offer theoretical, practical, and experimental evidence—from national elections to figure skating competitions—to support the arguments.
