Do judges impose harsher sentences on Friday afternoons? In this episode, Dr. Cass Sunstein, law professor, former administrator of the White House Office of Information and Regulatory Affairs, and co-author of Nudge: Improving Decisions about Health, Wealth, and Happiness, joins host Annie Duke, co-founder of the Alliance for Decision Education. They discuss the concept of noise, inconsistencies in human judgment that can arise even when people are presented with the same information. Annie and Cass talk about how we are more likely to believe things we hear repeatedly, even when they’re not true, and how “nudges” can positively influence our choices without us realizing it. Cass also sheds light on the surprising impact group polarization has on everyday decision-making, including the tendency of juries to impose harsher sentences collectively than any individual jurors would choose alone. This has big implications for the group decisions we make every day at work, at home, and in our families!
