This chapter analyzes judicial decision making from the perspective of motivation. Students of judicial behavior have focused on judges’ motivations, but their inquiries into motivation could be broader and deeper. The chapter presents four issues on which scholarship in psychology can enhance our understanding of judges’ motivations: the linkage between proximate goals (such as achieving good public policy) and more fundamental motivations, the energizing dimension of motivation (the level of effort devoted to a task), variation in motivation across judges and situations, and the relationship between motivation and cognition. The chapter concludes by considering the implications of its inquiry into motivation for the key questions in the study of judicial behavior, including the relative importance of legal and policy considerations in judges’ decision making and the extent to which judges behave strategically.
