How can cognitive dissonance help you as a communicator

First I would like to explain cognitive dissonance. Cognitive dissonance is the tension which comes from holding two conflicting thoughts in the mind at the same time. Mastering the principals of cognitive dissonance help you to better communicate by bringing to light the thought process needed to determine what will make an encounter with another more positive or a product or service more enticing to the consumer. Cognitive dissonance makes you think and feel one way when you had already thought and felt another. As a communicator I would use cognitive dissonance to persuade an audience to feel and think as I do and continue to perceive me as being right. This may seem arrogant to some but consider it, each writer or story teller is doing the same thing. They are trying to influence the reader or listeners thoughts. They want you to agree with them, and if you don't in the beginning, they want to convince you to do so by appearing to be more knowledgeable than you on the subject.
