Sarah 's attitude towards her parents' nighttime ban was changed by the advice of a friend who was with her. Some of the factors that led Sara 's decision was that she wanted to join the party with her friends yet, although she knew that she would break parents' nighttime ban. Another factor is that Sarah thinks that if you do not go with your friends that night, you will lose something important at the party. Cognitive dissonance is a person who feels uncomfortable by having two or more opposing ideas.
In the 1950s, social psychologist Leon Festinger researched cognitive dissonance in the observational study of the first final judgment cult. Festinger explains cognitive dissonance as discomfort of two contradictory ideas. In the face of inconsistent evidence, faith becomes more permanent. Cults are extreme examples of everyday phenomena. Even if you should work before the project deadline, you think you will also experience cognitive dissonance if you think you can not stop the carnival of YouTube videos. The degree of cognitive disharmony is directly related to your importance to faith
The great social psychologist Festinger has created the term cognitive dissonance. Cognitive dissonance is caused by tension between desire and belief. This discrepancy can cause discomfort and anxiety. Discomfort (incongruity) encourages individuals to alleviate discrepancies between personal wishes and beliefs. People do their best to eliminate or alleviate this discomfort. After all, in violation of human wishes and intentions, we violate the fundamental needs of human beings, we consider ourselves as a reasonable and consistent person.
In 1956, American psychologist Leon Festinger introduced a new concept in social psychology: cognitive dissonance theory. If two concurrent cognitions are inconsistent, this creates a state of cognitive disagreement. Because disharmony experience is uncomfortable, this person tries to reduce it by changing their beliefs. Festinger started with a very simple proposition. If a person has two psychologically contradictory perceptions, he experiences dissonance: negative driving conditions (unlike hunger and thirst). Because disharmony experience is unpleasant, people will try to reduce it - by usually trying to find a way to change one or two perceptions to make them more coordinated. Festinger's achievement is a dynamic marriage between cognition and motivation. "
