Leon Festinger’s 1957 A Theory of Cognitive Dissonance is a key text in the history of psychology – one that made its author one of the most influential social psychologists of his time. It is also a prime example of how creative thinking and problem solving skills can come together to produce work that changes the way people look at questions for good. Strong creative thinkers are able to look at things from a new perspective, often to the point of challenging the very frames in which those around them see things. Festinger was such a creative thinker, leading what came to be known as the “cognitive revolution” in social psychology. When Festinger was carrying out his research, the dominant school of thought – behaviorism – focused on outward behaviors and their effects. Festinger, however, turned his attention elsewhere, looking at “cognition:” the mental processes behind behaviors. In the case of “cognitive dissonance”, for example, he hypothesized that apparently incomprehensible or illogical behaviors might be caused by a cognitive drive away from dissonance, or internal contradiction. This perspective, however, raised a problem: how to examine and test out cognitive processes. Festinger’s book records the results of the psychological experiments he designed to solve that problem. The results helped prove the existence for what is now a fundamental theory in social psychology.

In 1954 Leon Festinger, a brilliant young experimental social psychologist in the process of outlining a new theory of human behavior - the theory of cognitive dissonance - and his colleagues infiltrated a cult who believed the end of the world was only months away. How would these people feel when their prophecy remained unfulfilled? Would they admit the error of their prediction, or would they readjust their reality to make sense of the new circumstances?

′Dr. Joel Cooper has been at the very forefront of research on dissonance theory for decades now. In this book, he provides a brilliant and engagingly-written review of the 50-year history of dissonance research and a masterful account of the ensuing developments in the theory. The book will be an outstanding resource for readers familiar with dissonance research and an enlightening introduction for those who are not′ - Professor Russell H. Fazio, Ohio State University Why is it that people who smoke continue to do so knowing how bad it is for them? What drives people to committing adultery even though they inherently believe this is wrong? What′s the outcome of this contradiction in the mind? Cognitive dissonance has been an important and influential theory since Leon Festinger published his classic work in 1957. It is known by every social psychologist, most psychologists of any stripe, and the lay public, making its way into such mainstream publications as The New York Times with increasing frequency and accuracy. Ultimately, dissonance has become one of the most popularly known expressions of social psychological insights, making its way into the literature in consumer, health and economic behavior, and has become a frequently used explanation of political behavior in the popular press and magazines. In marking the 50th anniversary of the theory′s inception, Joel Cooper - arguably the scholar most associated with dissonance research in the past few decades - has presented a beautiful, modern and comprehensive analysis of the state of dissonance theory. This book charts the progress of dissonance theory, assessing its impact not only within our understanding of psychology but in everyday experiences as well. It should be important reading for students in social psychology, either undergraduate or graduate, but equally relevant to a host of other readers who need to understand or share the same passions for appreciating the significance of cognitive dissonance in the human psyche.

Leon Festinger's forty-year scrutiny of that "curious animal, the modern human being" fundamentally transformed psychological thinking and shaped an entire scientific field, that of social psychology. The twenty-four papers brought together for the first time in Extending Psychological Frontiers encompass the classic contributions and critical turning points of Festinger's long career. Spanning the post-war decades, this unprecedented volume reveals the full scope, diversity, and import of Festinger's work. Its thematic arrangement clarifies the complex network of problems that preoccupied Festinger and the unique imaginative style that characterized his intellect. Whether examining the voting behavior of Catholics and Jews, the meaning of minute eye movements, the decisions of maze-running rats, or the proselytizing behavior of cultists, Festinger consistently transcended the traditional bounds of the discipline. His theory of cognitive dissonance, which describes how people attempt to resolve the tensions that result when they hold simultaneously two inconsistent beliefs, challenged preexisting psychological theories and produced more important ideas and experimentation than any other development in social psychology. Major writings on group dynamics, decision making, and perceptual processes further underscore the impact of Festinger's research not only on psychology, but also on a wide range of intellectual fronts, from literary theory to ethnology and from historical studies to contemporary political analysis. Extending Psychological Frontiers is an invaluable resource, providing a comprehensive and coherent picture of an extraordinary body of work.

This volume describes advances in the theory of cognitive dissonance, from its origination in 1954 to the present day.

Through ten examples of ingenious experiments by some of psychology's most innovative thinkers, Lauren Slater traces the evolution of the century's most pressing concerns—free will, authoritarianism, conformity, and morality. Beginning with B. F. Skinner and the legend of a child raised in a box, Slater takes us from a deep empathy with Stanley Milgram's obedience subjects to a funny and disturbing re-creation of an experiment questioning the validity of psychiatric diagnosis. Previously described only in academic journals and textbooks, these often daring experiments have never before been narrated as stories, chock-full of plot, wit, personality, and theme.
