The Psychology of Judgment and Decision Making


Author: Scott Plous

Scott Plous focuses on the social aspects of decision making and includes everyday examples from medicine, law, business, education, and nuclear arms control, among other areas. Intended for non-specialists, this book highlights experimental findings rather than psychological theory and presents information in descriptive prose rather than through mathematics.

In a "Reader Survey" preceding the first chapter, readers are asked to answer questions that are taken from studies discussed later in the book. This brief (and entertaining) exercise allows readers to compare their answers with the responses people gave in the original studies and to better understand their own processes of choosing.

Plous explores the building blocks of judgment and decision making and contrasts historical models of decision making with recent models that take into account various biases in judgment. In addition, he examines judgments made by and about groups and discusses common traps in judgment and decision making.
