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. | 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.

Cognitive dissonance also results in people reading information that affirms their already established opinions, rather than referencing material that contradicts them. For example, a person who is politically conservative will only read newspapers and watch news commentary that is from conservative news sources. This bias appears to be particularly apparent when faced with deeply held beliefs, i.e., when a person has 'high commitment' to his or her attitudes. | Cognitive dissonance also results in people reading information that affirms their already established opinions, rather than referencing material that contradicts them.
