A classic illustration of cognitive dissonance is expressed in the fable The Fox and the Grapes by Aesop (ca. 620–564 BCE). In the story, a fox sees some high-hanging grapes and wishes to eat them. When the fox is unable to think of a way to reach them, he decides that the grapes are probably not worth eating, with the justification the grapes probably are not ripe or that they are sour (hence the common phrase "sour grapes"). This example follows a pattern: one desires something, finds it unattainable, and reduces one's dissonance by criticizing it. Jon Elster calls this pattern "adaptive preference formation".
Perhaps the most famous case in the early study of cognitive dissonance was described by Leon Festinger and others in the book When Prophecy Fails.The authors infiltrated a religious group that was expecting the imminent end of the world on a certain date. When that date passed without the world ending, the movement did not disband. Instead, the group came to believe that they had been spared in order to spread their teachings to others, a justification that resolved the conflict between their previous expectations and reality.
Smoking is a common example of cognitive dissonance because it is widely accepted that cigarettes can cause lung cancer, and smokers must reconcile their habit with the desire to live long and healthy lives. In terms of the cognitive dissonance theory, the desire to live a long life is dissonant with the activity of doing something that is likely to shorten one's life. The tension produced by these contradictory ideas can be reduced by any number of changes in cognitions and behaviors, including quitting smoking, denying evidence linking smoking to lung cancer, or justifying one's smoking through rationalization. For example, smokers could rationalize their behavior by concluding that only a few smokers become ill, that it only happens to very heavy smokers, or that if smoking does not kill them, something else will.
This case of dissonance could also be interpreted in terms of a threat to the self-concept. The thought, "I am increasing my risk of lung cancer" can be dissonant with the self-related belief, "I am an intelligent, reasonable person who makes good decisions." As it is often easier to make excuses or pass judgment than it is to change behavior or values, cognitive dissonance research contributes to the abundance of evidence in social psychology that humans are not always rational beings.
