Judges play a central role in the American legal system, but their behavior as decision-makers is not well understood, even among themselves. The system permits judges to be quite secretive (and most of them are), so indirect methods are required to make sense of their behavior. Here, a political scientist, an economist, and a judge work together to construct a unified theory of judicial decision-making. Using statistical methods to test hypotheses, they dispel the mystery of how judicial decisions in district courts, circuit courts, and the Supreme Court are made. The authors derive their hypotheses from a labor-market model, which allows them to consider judges as they would any other economic actors: as self-interested individuals motivated by both the pecuniary and non-pecuniary aspects of their work. In the authors' view, this model describes judicial behavior better than either the traditional “legalist” theory, which sees judges as automatons who mechanically apply the law to the facts, or the current dominant theory in political science, which exaggerates the ideological component in judicial behavior. Ideology does figure into decision-making at all levels of the federal judiciary, the authors find, but its influence is not uniform. It diminishes as one moves down the judicial hierarchy from the Supreme Court to the courts of appeals to the district courts. As The Behavior of Federal Judges demonstrates, the good news is that ideology does not extinguish the influence of other components in judicial decision-making. Federal judges are not just robots or politicians in robes.

A distinguished and experienced appellate court judge, Richard A. Posner offers in this new book a unique and, to orthodox legal thinkers, a startling perspective on how judges and justices decide cases. When conventional legal materials enable judges to ascertain the true facts of a case and apply clear pre-existing legal rules to them, Posner argues, they do so straightforwardly; that is the domain of legalist reasoning. However, in non-routine cases, the conventional materials run out and judges are on their own, navigating uncharted seas with equipment consisting of experience, emotions, and often unconscious beliefs. In doing so, they take on a legislative role, though one that is confined by internal and external constraints, such as professional ethics, opinions of respected colleagues, and limitations imposed by other branches of government on freewheeling judicial discretion. Occasional legislators, judges are motivated by political considerations in a broad and sometimes a narrow sense of that term. In that open area, most American judges are legal pragmatists. Legal pragmatism is forward-looking and policy-based. It focuses on the consequences of a decision in both the short and the long term, rather than on its antecedent logic. Legal pragmatism so understood is really just a form of ordinary practical reasoning, rather than some special kind of legal reasoning. Supreme Court justices are uniquely free from the constraints on ordinary judges and uniquely tempted to engage in legislative forms of adjudication. More than any other court, the Supreme Court is best understood as a political court.

What motivates judges as decision makers? Political scientist Lawrence Baum offers a new perspective on this crucial question, a perspective based on judges' interest in the approval of audiences important to them. The conventional scholarly wisdom holds that judges on higher courts seek only to make good law, good policy, or both. In these theories, judges are influenced by other people only in limited ways, in consequence of their legal and policy goals. In contrast, Baum argues that the influence of judges' audiences is pervasive. This influence derives from judges' interest in popularity and respect, a motivation central to most people. Judges care about the regard of audiences because they like that regard in itself, not just as a means to other ends. Judges and Their Audiences uses research in social psychology to make the case that audiences shape judges' choices in substantial ways. Drawing on a broad range of scholarship on judicial decision-making and an array of empirical evidence, the book then analyzes the potential and actual impact of several audiences, including the public, other branches of government, court colleagues, the legal profession, and judges' social peers. Engagingly written, this book provides a deeper understanding of key issues concerning judicial behavior on which scholars disagree, identifies aspects of judicial behavior that diverge from the assumptions of existing models, and shows how those models can be strengthened.

The Oxford Handbook of U.S. Judicial Behavior offers readers a comprehensive introduction and analysis of research regarding decision making by judges serving on federal and state courts in the U.S. Featuring contributions from leading scholars in the field, the Handbook describes and explains how the courts' political and social context, formal institutional structures, and informal norms affect judicial decision making. The Handbook also explores the impact of judges' personal attributes and preferences, as well as prevailing legal doctrine, influence, and shape case outcomes in state and federal courts. The volume also proposes avenues for future research in the various topics addressed throughout the book. Consultant Editor for The Oxford Handbooks of American Politics George C. Edwards III.

No sitting federal judge has ever written so trenchant a critique of the federal judiciary as Richard A. Posner does in this, his most confrontational book. He exposes the failures of the institution designed by the founders to check congressional and presidential power and resist its abuse, and offers practical prescriptions for reform.
