Hidden Brain

There are some topics about which it seems no amount of data will change people’s minds: things like climate change, or restrictions on gun ownership. Neuroscientist Tali Sharot says that’s actually for good reason. As a general rule, she says, it’s better to stick to your beliefs and disregard new information that contradicts them. But this also means it’s very difficult to change false beliefs. In this favorite episode from earlier this year, we look at how we process information, and why it’s so hard to change our views.

In this week’s Radio Replay, we bring you stories of fakes, phonies, and con men — and the people who fall for the false worlds they create. First, the tale of a middle-aged man who impersonates a series of women and gets thousands of men to fall in love with his creations. Then, we’ll hear about a painter who tricks the world’s greatest art experts into believing they’re looking at masterpieces.

How do you spend your money? On shoes, cars, coffee, fancy restaurants? You might think you use money just to, you know, buy stuff. But as Neeru Paharia explains, the way we spend often says a lot about who we are, and what we want to project. We use money to express our values — by going to the local coffee shop instead of Starbucks, or by boycotting — or buycotting — Ivanka Trump shoes. In this April 2017 episode of Hidden Brain, we explore the way we use money to tell stories about ourselves, and to ourselves.

All countries have national myths. The story of the first Thanksgiving, for example, evokes the warm glow of intercultural contact: European settlers, struggling to survive in the New World, and Native American tribes eager to help. As many of us learned in history class, this story leaves a lot out. This week on Hidden Brain, we explore a national secret: that from the time Christopher Columbus arrived in the New World until 1900, there were as many as five million Native American people enslaved. We’ll learn about this history, and the psychological forces that kept it unexamined for so long.

In moments of anger, it can be hard to take a deep breathor count to ten. But public health researcher Harold Pollack says five minutes of reflection can make all the difference between a regular life and one spent behind bars. This week, we visit a Chicago program that helps young men learn how to pause and reflect. Plus, we ask whether we should think of violence as a disease, similar to a blood-borne pathogen in its ability to spread from person to person.

What does the song “Satisfaction” by The Rolling Stones have in common with the periodic table of elements? Both are the products of dreams. The sleeping brain is far more active than we realize, argues neuroscientist Matthew Walker in this second part of our series on sleep.

Randy Gardner broke a world record in 1963, when he was only 17 years old. His feat? Going 11 days without sleeping. Randy, now 71, shares his wisdom about staying up past your bedtime — and why none of us should attempt to recreate his teenage stunt — on this week’s Hidden Brain.

Discussions about healthy living usually revolve around diet and exercise. Social interaction is often left out of the conversation, even though research shows that it’s critical to our well-being. On this week’s radio replay, we’ll explore research on the extremes of social interaction: from the consequences of constant connection, to the high cost of solitary confinement.

Coincidences can make the everyday feel extraordinary. But are they magical, or just mathematical? On this week’s Radio Replay, we explore our deep fascination with these moments of serendipity. New research suggests they reveal important things about how our minds work, and have a far more powerful effect on our lives than any of us imagine. We’ll also explore the phenomenon of “implicit egotism” — the idea that we’re drawn to people and things that remind us of ourselves.
