"My vote doesn't count." Or does it? Millions of people vote when the odds of their individual vote are a drop in the bucket, so why do we feel the need to do it? In this special mini-episode ahead of the US Midterm Elections, we explore the science behind voter turnout and the surprising power of social pressure. So, how much of our decision to vote comes from what we believe, and how much comes from the groups we belong to and the expectations of those around us? We unpack what this reveals about human behavior and why the same social forces influence everything from volunteering to recycling. The last day to vote is Tuesday, November 3rd. Make sure your voice is heard.

Happy Halloween! We're throwing it back as we dive into the spooky science of superstition—why we knock on wood, wear lucky socks, and believe in things that defy logic. From the psychology of control and uncertainty to research on how superstition both stresses and strengthens us, we mix science, humor, and a dash of Stevie Wonder to show why “superstition ain’t the way.” Topics [0:00] Happy Halloween from Behavioral Grooves!

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?

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.
