Cognitive Dissonance Definition. Cognitive dissonance occurs when tension arises between a person's attitudes or beliefs and a decision that contradicts those pre-existing modes of thinking. The psychological phenomenon also occurs when a person chooses between two equally attractive or equally unappealing options. According to the Business Dictionary's website, the most common example of cognitive dissonance in the business world is the occurrence of buyer's remorse..
For example, an augmented second and a minor third are identical as sounds in equal temperament, but in the Western notation tradition, the former is considered a dissonance, the latter a consonance. It should also be noted that the concepts consonance and dissonance are highly context-related.
