Most Saturday mornings I make a cup of coffee and listen to the week's "Point of Inquiry" interview. I admire D.J. Grothe, and wish I had his job. This week was particularly good. Carol Tavris studies my favorite subject- cognitive dissonance. Why do people conitune to believe things that are obviously false? Turns out the more evidence against the belief, the stronger someone tends to believe it. Turns out, people surround themselves in echo chambers of people who only say what they want to hear and they ignore counterpoint. They search selectively for a reason to bolster their preformed opinion. When evidence to the contrary comes up they do not seek to incorporate it, but to invalidate it. In the interview, Tavris delves into the unique human capacity for undaunted self-deception.
