Hidden Brain

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...

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...

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...

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...

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. For more information about this episode, please visit https://n.pr/2SxITco

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

If you listen closely to giggles, guffaws, and polite chuckles, you can discern a huge amount of information about people and their relationships with each other. This week, we talk with neuroscientist Sophie Scott about the many shades of laughter, from cackles of delight among close friends to the "canned" mirth of TV laugh tracks.

In 2009, an old man died in a California nursing home. His obituary included not just his given name, but a long list of the pseudonyms he'd been known to use. In this episode, we trace the life of Riley Shepard, a hillbilly musician, writer, small-time con man and, perhaps, a genius.

Maya Shankar was well on her way to an extraordinary career as a violinist when an injury closed that door. This week, we revisit our December 2015 conversation with Maya, in which she shares how she found a new path forward after losing an identity she loved.

The adage "be kind to others" is simple enough that even young children can understand it. But that doesn't mean adults always remember the importance of being kind or understand how compassion might affect them. This week, we look at the science of compassion, and why doing good things for others can make a big difference in your own life.

Paul Rozin has been studying the psychology and culture of food for more than 40 years. And he's come to appreciate that food fills many of our needs, but hunger is just one. On this week's Radio Replay, we chew over the profound role that food plays in our lives. Then, we spit it all out — we study the ick factor that turns us off to cockroaches, skunks, and poop. Rachel Herz explains the sensation of disgust, and why it doesn't always come naturally. For more information about the research...

Arguments and bickering can sour family gatherings during the holiday season. This week, we share tips on how to avoid miscommunication from our January 2018 conversation with actor Alan Alda. You might know him from his roles on television shows like M*A*S*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. His book is If I Understood You, Would I Have This Look on My Face? My Adventures in the Art and...

When a newspaper shuts down, there are obvious costs to the community it serves: job losses, fewer local stories. But new research suggests there's another consequence that's harder to spot—one that comes with a hefty price tag for residents. This week on Hidden Brain we ask, who bears the cost when nobody wants to pay? For more information about the research in this episode, visit https://n.pr/2zSPraS.
