This text, written by a philosopher and a social psychologist, emphasizes concrete applications of decision research to problems of everyday living, as well as to business, social, and political issues. The text contains scores of interesting examples and problems for analysis, ranging from personal decisions about medical treatment to Truman's decision to use the atomic bomb. There is no other text with such a wide-ranging coverage, with so practical an orientation, with such clear descriptions of the steps to effective decision making, and with so many end-of-chapter problems for analysis and practice.
