What is Cognitive Dissonance?

Cognitive Dissonance is when we feel a tension or uncomfortableness with ourselves when we have acted in a way that is unlike what we would normally accept as right or normal. For instance, if I were a person who is against telling lies or hurting people, and I go out and tell a great big whopper about an innocent waiter just to get a free dinner at a restaurant, I would feel really guilty about it, or uneasy and foolish.
