The text relates questions of personality psychology to questions of social psychology, and focuses on questions which the authors consider to be outside the mainstream of social psychology.

This book is divided into five sections, each of which elucidates and extends these theoretical conceptions. Part 1 provides a historical background and analytical framework for the rest of the book.

Thinking: A Memoir is both a personal history and an intellectual autobiography describing how people reason and make inferences about the world, why errors in reasoning occur and how much you can improve reasoning.
