The Judgment and Decision Making Laboratory conducts research in several areas including the understanding of basic trade-off mechanisms used to resolve the inherent problem of choosing among conflicting options; the dynamics of preference evolution; the dynamics of decisions over time with changing references; decisions about time and money, and judgments of nutrition and their effect in healthy eating.
