Philosopher, neuroscientist, and psychologist, Joshua Greene tells us how the brain generates morality and how his research may have solved the infamous trolley problem, and in so doing created a way to encourage people to contribute to charities that do the most good, and, in addition, play quiz games that can reduce polarization and possibly save democracy.

Can intellectual humility be measured? What influences it and affects it, limits it and enhances it? What even is it, scientifically speaking? We explore all of this and then play an episode of How to Be A Better Human featuring psychologist Tenelle Porter telling comedian Chris Duffy how she is researching how to conduct better research into intellectual humility.

What is misinformation? How does it differ from disinformation or just plain ‘ole propaganda? How do we protect ourselves from people with nefarious intentions using all of these things to affect our thoughts, feelings, and behaviors? That’s what we discuss in this episode with Matthew Facciani, social scientist and author of Misguided: Where Misinformation Starts, How it Spreads, and What We Can Do About It.

In 1974, two psychologists, Daniel Kahneman and Amos Tversky, as the New Yorker once put it, “changed the way we think about the way we think.” Before their landmark research went viral (in the way things went viral in the 1970s), the prevailing wisdom was that human beings were, for the most part, rational optimizers always making the kinds of judgments and decisions that best maximized the potential of the outcomes under their control. This was especially true in economics at the time. The story of how they generated a paradigm shift so powerful that it reached far outside economics and psychology to change the way all of us see ourselves is a fascinating tale, one that required the invention of something this episode is all about: The Psychology of Single Questions.
