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.

What We Got Wrong About the Stanford Prison Experiment
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?
