Judgment and decision making researchers have produced many insights to improve the capacity to decide. Decades of research have yielded an array of debiasing strategies that can improve judgments and decisions across settings in fields such as business, medicine, and policy. This chapter provides a guide to these strategies. It begins with a brief discussion of the sources of bias in decision making. The chapter explains decision readiness, which refers to whether an individual is in a position to make a good decision in a particular situation. It then turns to a review of debiasing techniques, organized according to whether they modify the person or the environment. The treatment of debiasing includes addressing both coherence-based biases that reflect logical inconsistencies and correspondence-based biases that reflect systematic misperceptions or misjudgments of reality. Finally, the chapter examines how organizations might alter the work environment through cognitive repairs to encourage better decisions.
