"This scholarly volume tackles what may be the toughest dilemma facing courts in the twenty-first century: How do judges and juries separate genuine, reliable scientific evidence from political and social commentary masquerading as science? The answer to this question affects almost every aspect of human existence, including the quality of our doctors, the reliability of our drugs, and our ability to tell the guilty from the innocent. The book will serve as a beacon to judges and lawyers who must struggle to find their way in this wilderness." � Alex Kozinski, Circuit Judge, United States Court of Appeals for the Ninth Circuit
