This new book introduces a new generation to the important insights of Paul Meehl. In addition to selected papers from the classic reader, Psychodiagnosis, this book features new material selected from Meehl's most influential writings. The resulting collection is a tour de force illustrating quantitative analysis of life science problems, an examination of the inadequacy of some methods of analysis, and a review of the application of taxometrics. A Paul Meehl Reader is organized into five content areas: Theory building and appraisal–how we discover and test the true causal relations of psychological constructs. Specific etiology–an examination of genetic, behavioral, and environmental etiology in psychopathology. Diagnosis and prediction–a review of the appropriate use of base rates in psychopathological research. Taxometrics–A look at Meehl's development of the method he invented. Thinking effectively about psychological questions–A critique of correlation research and the power of quantitative thinking in psychology. The Reader features section introductions to orient the reader and provide a context and structure for Paul Meehl's work. The section on diagnosis and prediction features problem sets with solutions to guide the reader through practical applications of the principles described. The accompanying DVD contains footage from Paul Meehl's engaging seminar on clinical versus statistical prediction. This book appeals to advanced students and professionals in psychology, sociology, law, education, human development, and philosophy. Equations and formulas are kept to a minimum. A prerequisite of algebra is required.
