Contributions to Psychology:

Leon Festinger is perhaps best known for his theory of cognitive dissonance. According to this theory, people experience tension or discomfort when their beliefs do not match their behaviors. People tend to seek consistency in their beliefs and perceptions. So what happens when one of our beliefs conflicts with another previously held belief? When there is a discrepancy between beliefs or behaviors, something must change in order to eliminate or reduce the dissonance.

Festinger is also know for his social comparison theory, which describes the process through which people come to know themselves by evaluating their own attitudes, abilities and beliefs in comparison with others.
