The Age of Expert Testimony: Science in the Courtroom - Report of a Workshop THE NATIONAL ACADEMIES National Academy of Sciences National Academy of Engineering Institute of Medicine National Research Council The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Bruce M. Alberts is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Wm. A. Wulf is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Kenneth I. Shine is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Bruce M. Alberts and Dr. Wm. A. Wulf are chairman and vice chairman, respectively, of the National Research Council.

The Age of Expert Testimony: Science in the Courtroom - Report of a Workshop Preface A dozen years ago, the Carnegie Corporation of New York established the Commission on Science, Technology, and Government to explore the increasing importance of scientific understanding to decision making in government. Reports issued under the auspices of that commission called attention to the interdependence of science and all three branches of the federal government, including its legal rules and institutions. Events over the past decade have confirmed the importance of the Carnegie Commission’s work by dramatizing the connections, and sometimes the tensions, between science and the law. In response to these connections and tensions, the National Academies created the Science, Technology and the Law Program (STL) in 1998 to more fully explore these issues. The STL Program initiated its work with a two-day meeting in March 2000. A major topic of that meeting, Scientific Evidence, was explored more fully in a workshop on September 7, 2000. This topic has drawn substantial current attention because of three recent Supreme Court cases that address the admissibility of scientific and other technical evidence in civil litigation. The purpose of the Scientific Evidence Workshop was to air fully all points of view about the controversial issue of admitting scientists and their testimony into the courtroom. The goal of the workshop was not to reach conclusions or recommendations, but to hear and consider all view-points from both legal and scientific leaders with long experience in the field of expert testimony. The current report attempts to be faithful to that

The Age of Expert Testimony: Science in the Courtroom - Report of a Workshop original intention by summarizing the proceedings and organizing them by topic; it does not advocate the kinds of specific recommendations commonly seen in reports of the National Academies. It should be pointed out that, while workshop participants did hold strong opinions about the admissibility of evidence and expert testimony, this summary does not attribute views to specific speakers. Issues of admissibility often become extremely complex in tort litigation, notably in the “toxic tort” litigation where a plaintiff may claim damage by a chemical or product produced by the defendant. Thus, it is anticipated that defendants will generally seek restrictions on the evidence that is admitted to establish liability, while plaintiffs will prefer more lenient standards for admitting such evidence. These points of view, which are central to issues of admissibility, can be perceived throughout the workshop summary. In light of the difficulties of deciding how to admit expert testimony in cases that often have great economic and personal consequences, the legal system itself must work as effectively as possible. Thus a primary goal of this workshop was to seek ways to improve communication between scientists, lawyers, judges, and juries. It is important to inform the scientific community about how and why science is presented in a certain manner in court, revealing why some points of view that find their way into the courtroom may seem “extreme” or outside the prevailing scientific community consensus. It is equally important to inform the legal community about the scientific method, the scientific concept of the “truth,” and the reasons why some of the most qualified scientists may be reluctant to testify in a courtroom. To these ends, this report does discuss a series of techniques—such as court-appointed witnesses, technical advi-sors, short courses, and other educational tools—that are being used to improve communication and understanding between the worlds of scientists and lawyers. Improved communication and understanding are fundamental to more effective litigation in an age when science and technology underlie many of the customs, decisions, and assumptions of our culture.
