Cognitive dissonance is a state in which the mind holds two or more incompatible thoughts or beliefs. These thoughts or beliefs are referred to as cognitions, which is a general term for evaluating, integrating, and interpreting thoughts or beliefs.
We want our beliefs and our thoughts to be consistent, and we want the way we behave to be consistent with how we feel we should behave.
When that doesn't happen, we find ourselves in the unpleasant state of being out of sync. We then try to alter that unpleasant state by integrating, justifying, or in some cases, rejecting one of these thoughts or beliefs because it is incompatible with the others.
EXAMPLE
You work at an office, and you've been going into the supply room to take some office supplies that you need; you brought these supplies home. You haven't taken very many things, but you keep going back every week to take a little bit more.EXAMPLE
You believe that health is very important, so you want to have a good diet. You pride yourself on eating healthy foods, such as fruits, vegetables, grains. However, you have a bad habit of eating chips and chocolate on cold winter nights.When we choose to express this dissonance, whether by justifying it, rejecting it, or in some way trying to integrate it, we can either escalate or de-escalate a conflict.
EXAMPLE
Taylor lives in a neighborhood where everyone is of the same cultural background. But new neighbors, an immigrant family, just moved in next door to her. They're from a culture that's different than that of everybody else who lives on the block, and Taylor's neighbors hold a few prejudices. Taylor notices that people are shunning the new family, making fun of them and being unwelcoming, and making snide comments about the family's different clothing and mannerisms.EXAMPLE
You find yourself competing with a coworker for a promotion; it's just between the two of you. You know that there's a very important project this coworker is involved with.Source: Adapted from Sophia tutorial by Marlene Johnson.
