While scholars in the past several decades have made great progress in explaining what judges do, there remains a certain lack of depth to our understanding. This volume grew from a belief that close examination of the psychological processes underlying judicial decision making can greatlyenrich this understanding. The collected essays map ways of incorporating key concepts and findings from psychology into the study of judging.The first section of the book takes as its starting point the fact that judges make many of the same judgments and decisions that ordinary people make and considers how our knowledge about judgment and decision-making in general applies to the case of legal judges. In the second section, chaptersfocus on the specific tasks that judges perform within a unique social setting and examine the expertise and particular modes of reasoning that judges develop to deal with their tasks in this unique setting. Finally, the third section raises questions about whether and how we can evaluate judicialperformance, with implications for the possibility of improving judging through the selection and training of judges and structuring of judicial institutions. Together the essays will foster a better understand how judges make decisions, and open new avenues of inquiry into influences on judicialbehavior.
