How Doctors Think defines the nature and importance of clinical judgment. Although physicians make use of science, this book argues that medicine is not itself a science but rather an interpretive practice that relies on clinical reasoning. A physician looks at the patient's history along with the presenting physical signs and symptoms and juxtaposes these with clinical experience and empirical studies to construct a tentative account of the illness. How Doctors Think is divided into four parts. Part one introduces the concept of medicine as a practice rather than a science; part two discusses the idea of causation; part three delves into the process of forming clinical judgment; and part four considers clinical judgment within the uncertain nature of medicine itself. In How Doctors Think, Montgomery contends that assuming medicine is strictly a science can have adverse side effects, and suggests reducing these by recognizing the vital role of clinical judgment. "This is a book that will be read with pleasure by anyone interested in how medicine is done and it is a book that should be required reading for all students starting their clinical training."--Journal of the Royal Society of Medicine "Montgomery has certainly written a piece that will stimulate people to think more deeply about medical and wider health professional practice. It is a text I will recommend to students and colleagues."--PsycCRITIQUES
