NEW YORK UNIVERSITY LAW REVIEW VOLUM:E 73 NOVEMEBER 1998 NUMBER 5 CHARTING THE INFLUENCES ON THE JUDICIAL MIND: AN EMPIRICAL STUDY OF JUDICIAL REASONING GREGORY C. SISK* MICHAEL HEISE:** ANDREW P. MoRmss*** In 1988, hundreds of federal districtjudges were suddenly confronted with the need to render a decision on the constitutionality of the Sentencing Reform Act and the newly promulgatedcriminal Sentencing Guidelines. Never before has a question of such importance and involving such significant issues of constitutional lan, man- dated the immediate and simultaneous attention of such a large segment of the fed- eral trial bench. Accordingly, this event provides an archetypalmodel for exploring the influence of social background,ideology, judicialrole and institution,and other factors on judicial decisionmaking. Based upon a unique set of written dccisions involving an identical legalproblem, the authors have produced an unprecedented empiricalstudy of judicial reasoning in action. By exploiting this treasure trove of * Professor of Law, Drake University ([email protected]). B.A., 1981, Montana State University, J.D., 1984, University of Washington. In 1988, 1 was a member of a small team of attorneys in the United States Department of Justice leading the government's defense against constitutional challenges to the Sentencing Guidelines in district courts and courts of appeals throughout the nation. I want to thank several people whose support and generous contribution of time and information were essential to this project. John Steer, general counsel, and Mary McDowell, staff attorney, at the United States Sentencing Com- mission, provided thoughtful advice on background research and access to invaluable data, while securing my agreement to protect the confidentiality of judges who had reported oral rulings on the constitutionality of the Sentencing Guidelines in 19S8. Professor Sheldon Goldman of the University of Massachusetts at Amherst very kindly shared information on American Bar Association ratings and racial background of judges from his invaluable database of information, thereby encouraging a young scholar to persevere with this pro- ject. Bill Davis at the National Archives Legislative Records Center spent many hours locating legislative materials on judicial nominees. Others reviewed drafts, provided valua- ble comments on substance and technique, shared data or information, assisted in other ways, or offered encouragement, including Frank Bowman, Robert Carp, Frank Cross, Barry Friedman, Sheldon Goldman, Stanley Ingber, Douglas Letter, Bryan Liang, Deborah Jones Merritt, Thomas Millet, and Kevin Saunders.
