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.

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

Looks at the different ways in which emotions influence beliefs.

Tell any smoker that his habit is unhealthy, and he most likely will agree. What mental process does a person go through when he or she continues to do something unhealthy? When an honest person tells a "white lie," what happens to his or her sense of integrity? If someone must choose between two equally attractive options, why does one's value judgement of the options change after the choice has been made? In 1954 Dr. Leon Festinger drafted a version of a theory describing the psychological phenomenon that occurs in these situations. He called it cognitive dissonance: the feeling of psychological discomfort produced by the combined presence of two thoughts that do not follow from one another. Festinger proposed that the greater the discomfort, the greater the desire to reduce the dissonance of the two cognitive elements. The elegance of this theory has inspired psychologists over the past four decades. Cognitive Dissonance: Perspectives on a Pivotal Theory in Social Psychology documents the on-going research and debate provoked by this influential theory.

In the fall of 1983, we began to organize a symposium entitled "General Social Psychological Theories of Group Behavior." Our goal was to encourage the extension and application of basic current social psychology to group behavior. The symposium was presented in the spring of 1984 at the Eastern Psychological Association convention in Baltimore and the interest that it generated led to discussions with colleagues and friends about similar efforts by social psychologists, eventually resulting in the present book. Some clarification about the contents is in order. First, the theories presented here are clearly social psychological in scope and level of analysis, as discussed in the Introduction (Chapter 1). However, we are not trying to encompass sociological, anthropological, political, or historical theoretical approaches to group behavior. Second, while the theories comprise a wide-ranging and representative, if not quite exhaustive, selection of social psychological theories of group behavior, there are some interesting and general perspectives that are not represented. For example, one perspective that is conspicuous by its absence is some variant of learning theory. Aside from the rare, notable exception (e.g., Buss, 1979), little work currently is being done on group behavior from a learning theoretic perspective. Our inclusion or exclusion of a theory reflects our judgment regarding its currency and accessibility to social psychological researchers.

Do traditional distinctions between "belief" and "knowledge" still make sense? How are differences between knowledge and belief understood in different cultural contexts? This book explores conflicts between various types of knowledge, especially between orthodox and heterodox knowledge systems, ranging from religious fundamentalism to heresies within the scientific community itself. Beyond addressing many fields in the academy, the book discusses learned individuals interested in the often puzzling spatial and cultural disparities of knowledge and clashes of knowledge.
