cognitive dissonancethe experience of competing, opposing or contradictory thoughts, attitudes or actions leading to a feeling of tension and the need to achieve consonance. The term was introduced by Festinger (1957). In his definition dissonant cognitions exist when Belief A implies the negation of Belief B. For example, ‘Smoking causes lung cancer’ is dissonant with ‘I smoke’. The dissonance can be reduced in a variety of ways, either by adjusting Belief A or Belief B. Belief A could be adjusted by disregarding medical reports that confirm the belief and by paying particular attention to sceptical reports. Belief B can be adjusted by smoking less, or smoking tobacco of a low carcinogenic type.
