What does it really take to change a habit? Charles Duhigg, journalist and author of The Power of Habit, joins us to explore how our understanding of habits has evolved and why lasting change may start with changing how we see ourselves. From the “habit window” and keystone habits to habit chaining and identity shifts, we challenge long-held assumptions about willpower and explore how small changes in behavior and perspective can lead to lasting transformation.

Have we misunderstood two of psychology’s most famous experiments? We revisit the Stanford Prison Experiment and the Robbers Cave experiment with science historians Thibault Le Texier and Gina Perry, who uncovered a much messier story behind the research we learned about in school. What can these experiments actually tell us about human behavior, and what happens when researchers become more invested in a specific conclusion than challenging their own assumptions?

Why do we do what we do? Behavioral Grooves explores the science of human behavior with researchers, authors, and thinkers who help us make sense of ourselves, each other, and the world around us.

Horse meat, kidneys, prostitution. What happens when the things people want to buy, sell, and trade collide with what society has deemed “off-limits”? Nobel Prize-winning economist Alvin “Al” Roth joins us to explore the behavioral science behind controversial markets, from repugnance and social norms to black markets, incentives, and informed consent. We also dig into his work redesigning the kidney exchange market and how asking a different question can open up new possibilities for solving seemingly impossible problems.
