Judging Science

Attempting to reconcile the law's need for workable rules of evidence with the views of scientific validity and reliability.

What is 'scientific knowledge' and when is it reliable? These deceptively simple questions have been the source of endless controversy. In 1993, the Supreme Court handed down a landmark ruling on the use of scientific evidence in federal courts. Federal judges may admit expert scientific evidence only if it merits the label 'scientific knowledge.' The testimony must be scientifically 'reliable' and 'valid.'

This book is organized around the criteria set out in the 1993 ruling. Following a general overview, the authors look at issues of fit--whether a plausible theory relates specific facts to the larger factual issues in contention; philosophical concepts such as the falsifiability of scientific claims; scientific error; reliability in science, particularly in fields such as epidemiology and toxicology; the meaning of 'scientific validity'; peer review and the problem of boundary setting; and the risks of confusion and prejudice when presenting science to a jury.

The book's conclusion attempts to reconcile the law's need for workable rules of evidence with the views of scientific validity and reliability that emerge from science and other disciplines.

Review text:

'Anyone, scientist, jurist, or layman, will better judge the reliability of scientific results from reading the mosaic of quotations from experts, with annotations and expansions by the authors, that make up the core of this important book.

-- Robert K. Adair, Sterling Professor Emeritus of Physics, Yale University

'Foster and Huber brilliantly illuminate the landscape of courtroom debates about the consequences and uncertainties of using science and technology in society. This *tour de force* is both a practical guide for citizens and journalists as well as a path-breaking clarification for judges and policy analysts.'

-- Rodney W. Nichols, President and Chief Executive Officer, New York Academy of Sciences
