Judging Better Together: Understanding the Psychology of Group Decision-Making on Panel Courts and Tribunals

While the psychological phenomena that affect group decision-making have been thoroughly investigated for decades, how these phenomena apply to decision-making by judges on panel courts is under-examined. This article examines the main psychological phenomena of group decision-making, both positive and negative, and considers their implications for panel courts and other groups of professional legal decision-makers such as adjudicators serving on tribunals. This article argues that experimental studies on judges and adjudicators testing the effects of these phenomena would improve understanding of legal decision-making by these groups and could help to devise ways to improve their decision-making processes to reach higher quality decisions. Some ideas and outlines for experimental studies are presented.
