Heavy viewers are exposed to greater amounts of violence, and are accordingly more fearful of the world. Gerbner also explained that the overuse of TV has created a more fearful populace (uky.edu).

Cognitive dissonance is when you have two good choices, you make your choice, but then you have second thoughts about your choice, so you downplay the other so that yours sounds better (uky.edu).
