Introduction
In his introductory chapter, Münsterberg summarizes the history of experimental psychology and its theoretical and practical contributions. In his opinion, the field had matured enough for the legal system to sit up and take notice. In a sense, Münsterberg’s entire book is an indictment of the legal profession for this neglect—an indictment that did not go unanswered. The response of John Henry Wigmore, a prominent American legal scholar, was so scathing that it almost single-handedly quelled the incipient law-psychology movement for a number of years. The chapter covers Wigmore’s criticisms in depth. The introductory chapter provides a historical sketch of the field of law-psychology as it has developed over the past 110 years, focusing particularly on the courts’ use (or lack thereof) of psychological research on legal topics.
