The Discomfort of Contradiction

In 1957, social psychologist Leon Festinger proposed the theory of "Cognitive Dissonance." This theory describes the mental discomfort (dissonance) experienced by a person who holds two or more contradictory beliefs, values, or ideas simultaneously. This discomfort is particularly acute when a person's behavior conflicts with their beliefs. For example, a person who cares deeply about the environment but drives a gas-guzzling car will likely experience cognitive dissonance.

Festinger argued that humans have an inner drive to hold all their attitudes and beliefs in harmony and avoid disharmony (dissonance). When dissonance occurs, people are motivated to reduce it. They can do this in three ways: changing their behavior, changing their belief, or justifying their behavior by adding a new cognition. In the case of the environmentalist driver, they might sell the car (change behavior), decide that climate change is a hoax (change belief), or convince themselves that their car is necessary for their job and they recycle to make up for it (justification).

One famous experiment illustrating this involved paying students to perform a boring task and then lie to another student, saying it was fun. Students paid $20 to lie felt little dissonance because the money was sufficient justification. However, students paid only$1 to lie felt significant dissonance; to resolve it, they actually convinced themselves that the task was enjoyable. This demonstrated that we often change our beliefs to match our actions when external justification is low.
