Mistakes Were Made - Carol Tavris [6]
At midnight, with no sign of a spaceship in the yard, the group felt a little nervous. By 2 A.M., they were getting seriously worried. At 4:45 A.M., Mrs. Keech had a new vision: The world had been spared, she said, because of the impressive faith of her little band. “And mighty is the word of God,” she told her followers, “and by his word have ye been saved—for from the mouth of death have ye been delivered and at no time has there been such a force loosed upon the Earth. Not since the beginning of time upon this Earth has there been such a force of Good and light as now floods this room.”
The group’s mood shifted from despair to exhilaration. Many of the group’s members, who had not felt the need to proselytize before December 21, began calling the press to report the miracle, and soon they were out on the streets, buttonholing passersby, trying to convert them. Mrs. Keech’s prediction had failed, but not Leon Festinger’s.

The engine that drives self-justification, the energy that produces the need to justify our actions and decisions—especially the wrong ones—is an unpleasant feeling that Festinger called “cognitive dissonance.” Cognitive dissonance is a state of tension that occurs whenever a person holds two cognitions (ideas, attitudes, beliefs, opinions) that are psychologically inconsistent, such as “Smoking is a dumb thing to do because it could kill me” and “I smoke two packs a day.” Dissonance produces mental discomfort, ranging from minor pangs to deep anguish; people don’t rest easy until they find a way to reduce it. In this example, the most direct way for a smoker to reduce dissonance is by quitting. But if she has tried to quit and failed, now she must reduce dissonance by convincing herself that smoking isn’t really so harmful, or that smoking is worth the risk because it helps her relax or prevents her from gaining weight (and after all, obesity is a health risk, too), and so on. Most smokers manage to reduce dissonance in many such ingenious, if self-deluding, ways.
Dissonance is disquieting because to hold two ideas that contradict each other is to flirt with absurdity and, as Albert Camus observed, we humans are creatures who spend our lives trying to convince ourselves that our existence is not absurd. At the heart of it, Festinger’s theory is about how people strive to make sense out of contradictory ideas and lead lives that are, at least in their own minds, consistent and meaningful. The theory inspired more than 3,000 experiments that, taken together, have transformed psychologists’ understanding of how the human mind works. Cognitive dissonance has even escaped academia and entered popular culture. The term is everywhere. The two of us have heard it in TV newscasts, political columns, magazine articles, bumper stickers, even on a soap opera. Alex Trebek used it on Jeopardy, Jon Stewart on The Daily Show, and President Bartlet on The West Wing. Although the expression has been thrown around a lot, few people fully understand its meaning or appreciate its enormous motivational power.
In 1956, one of us (Elliot) arrived at Stanford University as a graduate student in psychology. Festinger had arrived that same year as a young professor, and they immediately began working together, designing experiments to test and expand dissonance theory.3 Their thinking challenged many notions that were gospel in psychology and among the general public, such as the behaviorist’s view that people do things primarily for the rewards they bring, the economist’s view that human beings generally make rational decisions, and the psychoanalyst’s view that acting aggressively gets rid of
