Hidden Brain

There can be a lot of psychological noise involved in teaching. But what if we replaced all that mental chit chat....with a click? This week, we explore an innovative idea about how we learn. It will take us from a dolphin exhibit in Hawaii to a top teaching hospital in New York. It's about a method to quiet the noise. The sort of clutter that can turn learning into a minefield of misery.

Many parents think they can shape their child into a particular kind of adult. Psychologist Alison Gopnik says the science suggests otherwise. This week, we revisit our December 2017 conversation with Gopnik, who thinks we'd all be better off if we had a different understanding of the relationship between parents and kids.

All of us are time travelers. We go back in history to turning points in our lives, and imagine how things could have turned out differently. Psychologists refer to this as "counterfactual thinking." This week on Hidden Brain, we look at why some events prompt these "What if?" questions, while others do not. Hosted by Simplecast, an AdsWizz company.

Babies are speaking to us all the time, but most of us have no clue what they're saying. To researchers, though, the babbling of babies is knowable, predictable, and best of all, teachable to us non-experts. This week, we'll get a primer on how to decipher babbling — the unique dialect of tiny humans. Hosted by Simplecast, an AdsWizz company.

Olutosin Oduwole was an aspiring rapper and college student when he was arrested in 2007. He was charged with "attempting to make a terrorist threat." Prosecutors used his writings — which he maintains were rap lyrics — to build their case against him. The week, we revisit our June 2017 story about Oduwole, and explore how public perceptions of rap music may have played a role in his prosecution. Hosted by Simplecast, an AdsWizz company.

The Greek poet Archilochus wrote that "the fox knows many things, but the hedgehog knows one big thing." This week, we'll use the metaphor of the fox and the hedgehog as a way to understand the differences between tacticians and big-picture thinkers. We'll explore the story of a pioneering surgeon whose hedgehog tendencies led him to great triumphs, and a heartbreaking tragedy. This episode first aired in May 2017.

In 1924, a 17-year-old girl was admitted to the Virginia State Colony for Epileptics and Feebleminded. The superintendent of the colony classified her as "feeble-minded of the lowest grade, moron class." With that designation, this girl, Carrie Buck, was set on a path she didn't choose. What happened next laid the foundation for the forced sterilization of tens of thousands of people. This week, the story of the eugenics movement and one of the most tragic social experiments in American history. Hosted by Simplecast, an AdsWizz company.

Political correctness. Free speech. Terrorism. On this week's Radio Replay, we look at the language we use around race and religion, and what that language says about the culture in which we live.

How do you change someone's behavior? Most of us would point to education or persuasion. But what if the answer lies elsewhere? Today we explore a revolutionary insight about human nature, one that will take us on a journey from Budapest to the hills of Rwanda. Hosted by Simplecast, an AdsWizz company.

Editor’s note: Since this episode first aired, researchers have raised concerns about a number of studies authored by Dan Ariely, including one cited in this episode. That study included data from an insurance company that purported to show that people are more truthful when they sign an ethics declaration at the beginning of a form than at the end. In an independent review, a group of researchers found evidence of data fabrication in that study. You can read more about their findings here, along with Dan Ariely’s response. The insurance company that provided the data, The Hartford, released a statement to NPR’s Planet Money in July 2023. In that statement, the company said that it had done a review of its records and that “there appear to be significant changes made to the size, shape and characteristics of our data after we provided it and without our knowledge or consent.” You can hear the full Planet Money story and read the full statement from The Hartford here. Additionally, a second study cited in this episode – in which Ariely reported reduced cheating among test-takers asked to recall the Ten Commandments before taking the test – has not stood up to replication by other researchers. You can read more about that here. We all lie. But what separates the average person from the infamous cheaters we see on the news? Dan Ariely says we like to think it's character — but in his research he's found it's more often opportunity. Dan Ariely is a professor at Duke University and the author of the book The Honest Truth About Dishonesty: How We Lie to Everyone — Especially Ourselves. We spoke to him in March 2017.

When you're hungry, it can be hard to think of anything other than food. When you're desperately poor, you may constantly worry about making ends meet. When you're lonely, you might obsess about making friends. This week, we bring you a March 2017 episode about the psychological phenomenon of scarcity. Researchers say this form of tunnel vision can affect our ability to see the big picture and cope with problems in our lives. Hosted by Simplecast, an AdsWizz company.

Boys get the message at a young age: don't show your feelings. Don't rely on anyone. This week, we take a close look at misguided notions of masculinity in the United States. We explore how those notions create stressed-out romantic relationships, physical health problems, and a growing epidemic of loneliness. Plus, we consider how we might begin to tell a different story about what it means to be a man. Hosted by Simplecast, an AdsWizz company.

Do humans act rationally? Economic theory has long told us the answer is "yes." But a half century ago, two psychologists — Daniel Kahneman and Amos Tversky — began to challenge this notion. Their work laid the foundation for behavioral economics and influenced many scholars who've followed in their footsteps. This week, we mark our 100th episode by talking with Daniel Kahneman about his collaboration with Tversky, and how their work transformed our thinking about judgment, memory, and the mind itself.

More women are running for political office than ever before in American history. But in politics and many other fields, women still struggle to attain positions of power. Researchers say they're often trapped in a "double bind" — a series of unconscious, interlocking stereotypes we have about men, women and the nature of leadership. This week, we take a closer look at the double bind as we revisit a favorite episode from October 2016. Hosted by Simplecast, an AdsWizz company.

Envy is one of the most unpleasant of all human emotions. It also turns out to be one of the most difficult for researchers to study. And yet, there's mounting evidence that envy is a powerful motivator. This week, we explore an emotion that can inspire us to become better people — or to commit unspeakable acts.

Marriage is hard — and there are signs it's becoming even harder. This week on Hidden Brain, we examine how long-term relationships have changed over time, and whether we might be able to improve marriage by asking less of it.

Nearly a quarter century ago, a group of women accused a prominent playwright of sexual misconduct. For the most part, the allegations went nowhere. In 2017, in the midst of the #MeToo movement, more women came forward to accuse the same playwright of misconduct. This time, everyone listened. On this episode, we explore the story through the lens of social science research and ask, "Why Now?" What has changed in our minds and in our culture so that allegations of sexual harassment and assault are being taken so much more seriously than they were in the past? A note: This story includes descriptions of sexual harassment and assault. It may not be suitable for all listeners. Hosted by Simplecast, an AdsWizz company.

Call it adulation, adoration, idolization: we humans are fascinated by glamour and power. But this turns out to be only one side of our psychology — we also feel envious and resentful of the rich and powerful. In this Radio Replay, we explore the evolutionary history behind this ambivalence. Plus, we look at how we gain influence, and what happens to us once we have it.

We've all experienced miscommunications. Their consequences can range from hilarious... to disastrous. The actor Alan Alda — yes, THAT Alan Alda — wants to help us avoid them. You might know him from his roles on television shows like MAS*H, The West Wing and 30 Rock, but in recent years Alda has also focused on helping scientists, and the rest of us, communicate better.

Our airwaves are filled with debates about immigrants and refugees. Who should be allowed in the United States, who shouldn't, and who should decide?

The tone of American politics can be...nasty. But is this nastiness really worse than in previous eras, and if so, what does that mean for our democracy? Historian David Moss takes the long view — arguing that American democracy is much more resilient than we realize.

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.

All social classes have unspoken rules. From A-list celebrities to teachers, doctors, lawyers, and journalists — there are social norms that govern our decisions, whether we realize it or not. This week on Hidden Brain, the invisible qualities that all celebrities have in common, and how our interest in them builds because of cues we get from one another. Later in the episode, we look at another elite group: the yoga-loving, Whole Foods-shopping, highly-educated group that researcher Elizabeth Currid-Halkett calls the "aspirational class."

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.

The desire to find our tribe is universal. We like to know who we are and where we belong. This fascination has led to a thriving industry built on the marketing and sale of personality tests. These tests offer individuals — and, increasingly, employers — quick and easy insights that can be used to make some of life's biggest decisions. But most fail to stand up to scientific scrutiny. This week, we delve into the world of personality testing, and explore the many different ways we assess personality and potential — from the Chinese zodiac to Harry Potter houses to the Myers-Briggs test.

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. Hosted by Simplecast, an AdsWizz company.

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. Hosted by Simplecast, an AdsWizz company.

In moments of anger, it can be hard to take a deep breath or 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. Hosted by Simplecast, an AdsWizz company.

Randy Gardner broke a world record in 1963, when he was only 17 years old. His feat? Going 11 days without sleeping.

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.

The simple "to-do" list may be one of humanity's oldest tools for keeping organized. But checklists are also proving essential in many modern-day workplaces, from operating rooms to the cockpits of jumbo jets. This week, we explore the power of the humble checklist to help us stay on track and focus on what's important, particularly when pressure is intense and the stakes are high.

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. Hosted by Simplecast, an AdsWizz company.

We don't always do what we're supposed to do. We don't save enough for retirement. We order dessert — even when we're supposed to be dieting. In other words, we misbehave. That's the title of Richard Thaler's most recent book: Misbehaving: The Making of Behavioral Economics. If you've read Thaler's previous book, Nudge, you know he's an economist who studies why people don't really act the way traditional economists say they will. Thaler recently won a Nobel Prize for his contributions to the field of behavioral economics — so we thought we'd celebrate by giving you this encore episode. It's still one of our favorites.

Gender is one of the first things we notice about the people around us. But where do our ideas about gender come from? Can gender differences be explained by genes and chromosomes, or are they the result of upbringing, culture and the environment? This week, we delve into the debate over nature vs. nurture, and meet the first person in the United States to officially reject the labels of both male and female, and be recognized as "non-binary."

"Be the change you wish to see in the world." It's a popular quote that's made its way onto coffee mugs and bumper stickers — but it's not the easiest principle to live. On this week's Hidden Brain, we meet Royce and Jessica James, a couple who decided to raise their daughter in a gender-neutral way. It was far harder than they ever could have imagined.

We all know casual sex isn't about love. But what if it's not even about lust? Sociologist Lisa Wade believes the pervasive hookup culture on campuses today is different from that faced by previous generations.
