Renowned social psychologists Carol Tavris and Elliot Aronson are the co-authors of Mistakes Were Made (But Not By Me), a book which explores the science of cognitive biases and discusses how the human brain is wired for self-justification. In this episode, Carol and Elliot discuss how our desire to reconcile mental conflicts adversely affects many aspects of society. The two give real-world examples to demonstrate the pitfalls in attempts to reduce mental conflict, or dissonance. The examples reveal that no one is immune to dissonance reduction behavior, how intellectual honesty can be trained and lastly, how to think critically in order to avoid engaging in harmful dissonant behaviors.
