Hidden Brain

We generally think of pain as something to be avoided. But psychologist Paul Bloom says that as much as we're wired to avoid suffering, we also seek it out. This week, we begin a two-part mini series about the curious pleasure we take in certain forms of pain.

Revenge often feels sweet, but what price do we pay for seeking it out? Researcher James Kimmel, Jr. proposes a radical theory: our desire for vengeance operates like an addiction in the brain. This week, how “revenge addiction” plays out in our everyday lives — and on a global scale.

Have you ever encountered someone who clearly knows you, but you have no idea who they are? This week, we feature a classic Hidden Brain episode about people on opposite ends of the facial recognition spectrum. Then, in the second part of the show, we bring you another perspective on facial recognition from the Revisionist History podcast. Host Malcolm Gladwell struggles with identifying faces, while producer Lucie Sullivan is exceptional at it.

You probably know someone who thinks they know more about something than they really do. But you could never be described that way . . . could you? This week, cognitive scientist Phil Fernbach explains the "illusion of knowledge" — the fact that we think we understand the world in much greater detail than we actually do. He'll explore why this happens, and how to close the gap between what we know and what we think we know. Hidden Brain is about to go on tour! Join Shankar in a city near you as he shares key insights from the first decade of the show. For more info and tickets, go to https://hiddenbrain.org/tour/

Forgetting something — whether it's a colleague's name or where we put our keys — can be deeply frustrating. This week, psychologist Ciara Greene helps us explore the science of forgetting. We look at why our minds hold on to some memories for a lifetime, but discard others within seconds. And we grapple with a question many people ask themselves: Is my forgetfulness a sign that something is wrong with me?
