For more than a million years, man's utter dependence on technology has been producing a host of intricate problems. For example, we steadily reduce the need for human labor while finding ways to increase life expectancy. We mass produce the automobile without grasping the harsh effects it leaves on the environment. The Human Legacy concerns the evolution and development of man-physically, socially, psychologically-into the latest version of the species we see around us today. The author paints an intriguing picture of man, living in complex societies and trying to solve the unanticipated consequences of action.

Leon Festinger's theory of cognitive dissonance has been widely recognized for its important and influential concepts in areas of motivation and social psychology. The theory of dissonance is here applied to the problem of why partial reward, delay of reward , and effort expenditure during training result in increased resistance to extinction.The author contends that a state of impasse exists within learning theory largely because some of its major assumptions stand in apparent opposition to cetain well-established experimental results. The book puts forward a new theory that seems to reconcile these data and assumptions. This new theory can account for data with which other theories have difficulty: it integrates empirical phenomena that have been regarded as unrelated, and it is supported by the results of experiments designed specifically to test its implications. These experiments are fully described in the text.

Tillfälligt slut
In 1954 Leon Festinger, a brilliant young experimental social psychologist in the process of inventing a new theory of human behavior - the theory of cognitive dissonance - and two of his colleagues, Henry Riecken and Stanley Schachter, 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, as Festinger predicted, readjust their reality to make sense of the new circumstances?Not only is When Prophecy Fails of great historical importance as the first test of a powerful theory, but it is also a surprisingly touching account of what happens to ordinary people under extraordinary circumstances.
