Belief perseverance biases are closely related to the psychological concept of cognitive dissonance, a bias I will review in the next chapter. Cognitive dissonance is the mental discomfort that one feels when new information conflicts with previously held beliefs or cognitions. To resolve this discomfort, people tend to notice only information of interest to them (called selective exposure), ignore or modify information that conflicts with existing beliefs (called selective perception), and/or remember and consider only information that confirms existing beliefs (called selective retention). Aspects of these behaviors are contained in the biases categorized as belief perseverance. The six belief perseverance biases covered in this book are: cognitive dissonance, conservatism, confirmation, representativeness, illusion of control, and hindsight.
