In the field of psychology, cognitive dissonance is described as the mental phenomenon of people existing with unwittingly and fundamentally conflicting cognition. [1] Being confronted by situations that challenge this dissonance may ultimately result in some change in their cognitions or actions to cause greater alignment between them so as to reduce this dissonance.

Mistakes Were Made (but Not by Me) is a 2007 non-fiction book by social psychologists Carol Tavris and Elliot Aronson.It deals with cognitive dissonance, confirmation bias, and other cognitive biases, using these psychological theories to illustrate how the perpetrators (and victims) of hurtful acts justify and rationalize their behavior.

Dissonance is bothersome in any circumstance but it is especially painful when an important element of self ...
In Balcetis and Dunning's study, participants were given the choice of performing a task that induced cognitive dissonance, such as pushing themselves up a hill while kneeling on a skateboard. After choosing to complete this task (but prior to completing it), participants perceived the slope of the hill to be less steep than a control group who ...
If an individual can increase dissonance to the point where it is greater than the resistance to change, he will change the cognitive elements involved, reducing or even eliminating dissonance. Once dissonance is increased sufficiently, an individual may bring himself to change, hence eliminating all dissonance ( Festinger 1957 , pp. 127–131).
In psychology, cognitive dissonance is the mental stress or discomfort experienced by an individual who holds two or more contradictory beliefs, ideas, or values at the same time, or is confronted by new information that conflicts with existing beliefs, ideas, or values.
For example, Shultz and Lepper (1996) noted that in thinking about cognitive dissonance in terms of parallel constraint satisfaction processes, it becomes clear that cognitive consistency phenomena—such as those studied by dissonance researchers—are not the result of atypical or unusual cognitive processes but rather are the direct result ...
