Hidden Brain latest podcasts.
It happens to all of us: someone recognizes you on the street, calls you by name, and says hello. You, meanwhile, have no idea who that person is. Researchers say this struggle to read other faces is common. This week on Hidden Brain, we revisit a favorite 2016 episode about "super-recognizers" and the rest of us.
Smarts matter. But other factors may play an even bigger role in whether someone succeeds. This week, we speak with Nobel Prize-winning economist James Heckman about the skills that predict how you'll fare in life. We'll also look at programs that build these skills in the neediest of children – and new research that suggests the benefits of investing in kids and families can last for generations.
If you've taken part in a religious service, have you ever stopped to think about how it all came to be? How did people become believers? Where did the rituals come from? And what purpose does it all serve? This week, we bring you a July 2018 episode with social psychologist Azim Shariff. He argues that we should consider religion from a Darwinian perspective, as an innovation that helped human societies to thrive and flourish.
Placebos belong in clinical trials, not in the doctor's office. At least, that's been the conventional wisdom for decades. This week, we ask whether placebos have more to offer than we've realized, and what they might teach us about healing. For research related to this episode, please visit: https://n.pr/2B9v2B0
If you've ever flown in economy class on a plane, you probably had to walk through the first class cabin to get to your seat. Maybe you noticed the extra leg room. The freshly-poured champagne. Maybe you were annoyed, or envious. Social psychologist Keith Payne says we tend to compare ourselves with those who have more than us, but rarely with those who have less. This week, we explore the psychology of income inequality, and how perceptions of our own wealth shape our lives.
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 revisit our 2017 episode about 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.
For generations, living openly as a gay person in the United States was difficult, and often dangerous. But there's been a dramatic change in public attitudes toward gay people. This week, we explore one of the most striking transformations of public attitude ever recorded. And we consider whether the strategies used by gay rights activists hold lessons for other groups seeking change.
Chaos is a part of all of our lives. Sometimes we try to control it. And other times, we just have to live with it. On this week's Hidden Brain, we bring you two of our favorite stories about coping with chaos. They come from our 2016 episodes "Panic in the Streets" and "Embrace the Chaos."
In December 1988, two pairs of twin boys were born in Colombia. One twin from each pair was accidentally given to the wrong mother — a mistake that wasn't discovered for decades. The twins' story is a tragedy, a soap opera, and a science experiment, all rolled into one. It also gives us clues about the role that genes and the environment play in shaping our identities. We talk with psychologist Nancy Segal about her work with twins, and her encounters with these now-famous brothers. For research related to this episode, please visit https://n.pr/2uvpvPe
All social classes have unspoken rules. From A-list celebrities to teachers, doctors, lawyers, and journalists — there are social norms that govern us, whether we realize it or not. This week on Hidden Brain, we look celebrity culture, as well as another elite group: the yoga-loving, Whole Foods-shopping, highly-educated people whom one researcher calls the new "aspirational class." This episode is from December 2017.
From stone statues to silicone works of art, we have long sought solace and sex from inanimate objects. Time and technology have perfected the artificial lover: today we have life-size silicone love dolls so finely crafted they feel like works of art. Now, with the help of robotics and artificial intelligence, these dolls are becoming even more like humans. This week we talk with researcher Kate Devlin about the history of the artificial lover, and consider what love and sex look like in the age of robots.
You own your body. So should you be able to sell parts of it? This week, we explore the concept of "repugnant transactions" with the man who coined the term, Nobel Prize- winning economist Al Roth. He says repugnant transactions can range from selling organs to poorly-planned gift exchanges — and what's repugnant in one place and time is often not repugnant in another.
Annie Duke was about to win $2 million. It was 2004, and she was at the final hand of the World Series of Poker Tournament of Champions. But as a woman at a table full of men, she wasn't sure she deserved to be there. In this week's Radio Replay, we tell the stories of two people who grappled with gender stereotypes on the job. Annie Duke shares her experiencing at the World Series of Poker, and then we hear the story of Robert Vaughan, a former Navy sailor who decided to pursue a new career as a nurse.
Our modern world is saturated with awards. From elementary school classrooms to Hollywood to the hallways of academia, there's no shortage of prizes — and people who covet them. Yet we rarely stop to ask, do they work? We pose that question to economist Bruno Frey, who argues that awards can have a powerful, positive effect on our behavior — but only if they're designed well.
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, we revisit a 2018 episode about the eugenics movement and one of the most tragic social experiments in American history.
Today, more and more of us are living through the people on our screens and in our headphones. It's a world just beyond our reach, where we can get the ocean without the seaweed and sunsets without clouds. Where we can experience love without the risk of rejection. It's not real, but for many of us, it's close enough. This week, we explore the dangers, and the delights, of living vicariously.
This week, we search for the answer to a deceptively simple question: why is the brain divided? Psychiatrist Iain McGilchrist explains why popular distinctions between the "left brain" and "right brain" aren't supported by research. He argues that one hemisphere has come to shape Western society — to our detriment.

What happens when we connect with people whose view of the world is very different from our own? In this month's Radio Replay, we bring you stories about the relationship between diversity, conflict, and creativity. This episode features reporting from our July 2018 podcast, "The Edge Effect," and from one of our 2016 shows, "Tribes and Traitors."
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. This episode originally aired in May 2018.
We like to think that science evolves in a way that is...rational. But this isn't always the case. This week, we look at how information and misinformation spread in the world of science, and why evidence is often not enough to convince others of the truth. We talk with philosopher and mathematician Cailin O'Connor. For more information about this episode, please visit https://n.pr/2S3onzK
