Cognitive Dissonance

There will be lots of this going on up until the election...


In psychology, cognitive dissonance is an uncomfortable feeling or stress caused by holding two contradictory ideas simultaneously. The theory of cognitive dissonance proposes that people have a fundamental cognitive drive to reduce this dissonance by modifying an existing belief, or rejecting one of the contradictory ideas.

Often one of the ideas is a fundamental element of ego, like "I am a good person" or "I made the right decision." This can result in rationalization when a person is presented with evidence of a bad choice, or in other cases. Prevention of cognitive dissonance may also contribute to confirmation bias or denial of discomforting evidence.
