Hidden Brain

We know that we live in an ever-changing world, but one thing we often overlook is demographic change. Whether the world's population is growing or shrinking can affect many aspects of our lives, from the number of kids we have to the likelihood that we'll live to old age. This week on Hidden Brain, we explore how our planet's population is changing, and what that means for us in the century to come. Hosted by Simplecast, an AdsWizz company.

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, which we originally released in 2019, we trace the life of Riley Shepard, a hillbilly musician, writer, small-time con man and, perhaps, a genius.

Think about the last time you asked someone for something. Maybe you were nervous or worried about what the person would think of you. Chances are that you didn't stop to think about the pressure you were exerting on that person. This week, we explore a phenomenon that psychologists refer to as "egocentric bias," and look at how this bias can lead us astray. 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.

Many Americans feel an obligation to keep up with political news. But maybe we should be focusing our energies elsewhere. Political scientist Eitan Hersh says there's been a rise in "political hobbyism" in the United States. We treat politics like entertainment, following the latest updates like we follow our favorite sports teams. Instead, he says, we should think of politics as a way to acquire power and persuade our neighbors to back the issues we support. Hosted by Simplecast, an AdsWizz company.

There can be a lot of psychological noise involved in teaching. But what if we replaced all that mental clutter...with a click? This week, we bring you a 2018 episode exploring 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 that can turn learning into a minefield of misery. Hosted by Simplecast, an AdsWizz company.

Where is the line between what is real and what is imaginary? It seems like an easy question to answer: if you can see it, hear it, or touch it, then it's real, right? But what if this way of thinking is limiting one of the greatest gifts of the mind? This week, we meet people who experience the invisible as real, and learn how they hone their imaginations to see the world with new eyes. Hosted by Simplecast, an AdsWizz company.

After a disaster happens, we want to know whether something could have been done to avoid it. Did anyone see this coming? Many times, the answer is yes. So why didn't the warnings lead to action? This week, we revisit a favorite 2018 episode about the psychology of warnings. We visit a smelly Alaskan tunnel, hear about a gory (and fictional) murder plot, and even listen to some ABBA.

What's the point of money? The answer might seem obvious: we need it to get paid for our work, and to buy the things we need. But there's also a deeper way to look at the role of money in our lives. This week we explore an anthropologist's take on the origin story of money. What if the cash and coins we carry are not just tools for transactions, but manifestations of human relationships?

What would drive someone to take another person's life? When researchers at the University of Chicago asked that question, the answer was a laundry list of slights: a stolen jacket, or a carelessly lobbed insult. It made them wonder whether crime rates could be driven down by teaching young men to pause, take a deep breath, and think before they act. In this 2017 episode, we go inside a program that teaches Chicago teens to do just that. We also explore what research has found about whether this approach actually works.

At the beginning of the year, many of us make resolutions for the months to come. We resolve to work out more, procrastinate less, or save more money. Though some people stick with these aspirations, many of us fall short. This week, psychologist Wendy Wood shares what researchers have found about how to build good habits — and break bad ones.

Why do we fall for surprise endings? It turns out that our capacity to be easily fooled in books and movies is made possible by a handful of predictable mental shortcuts. In this 2018 conversation, we talk with Vera Tobin, one of the world's first cognitive scientists to study plot twists. She says storytellers have been exploiting narrative twists and turns for millennia — and that studying these sleights of hand can give us a better understanding of the contours of the mind.

Our memories are easily contaminated. We can be made to believe we rode in a hot air balloon or kissed a magnifying glass — even if those things never happened. So how do we know which of our memories are most accurate? This week, psychologist Ayanna Thomas explains how memory works, how it fails, and ways to make it better.

There's a core belief embedded in the story of the United States — the American Dream. Today we look at the state of that dream as we revisit our 2018 conversation with economist Raj Chetty. We'll ask some questions that carry big implications: can you put an economic value on a great kindergarten teacher? How is it that two children living just a few blocks from each other can have radically different chances in life? And what gives Salt Lake City an edge over Cleveland when it comes to offering people better prospects than their parents? Hosted by Simplecast, an AdsWizz company.

In a fit of anger or in the grip of fear, many of us make decisions that we never would have anticipated. This week, we look at situations that make us strangers to ourselves — and why it's so difficult to remember what these "hot states" feel like once the moment is over.

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.

Many of us believe we know how we'd choose to die. We have a sense of how we'd respond to a diagnosis of an incurable illness. This week, we have the story of one family's decades-long conversation about dying. What they found is that the people we are when death is far in the distance may not be the people we become when death is near. Hosted by Simplecast, an AdsWizz company.

Anyone who's tried (and failed) to follow a diet knows that food is more than fuel. This week, we revisit our 2018 episode about the psychology behind what we eat, what we spit out, and when we come back for more. Hosted by Simplecast, an AdsWizz company.

Can we affect the rise and fall of the economy? This week on Hidden Brain, we talk with Nobel Prize-winning economist Robert Shiller about the powerful ways in which stories and psychology shape our economic lives.

What makes the mind of a human different from that of other animals? Psychologist Laurie Santos says we can't know the answer to that question if we only study humans. This week, we turn to Laurie's work with monkeys to understand which parts of human behavior are distinct, and which we share with other species. 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 bring you a favorite 2018 episode about misguided notions of masculinity in the United States.

Turn on the news or look at Twitter, and it's likely you'll be bombarded by outrage. Many people have come to believe that the only way to spark change is to incite anger.

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 revisit our May 2018 primer on how to decipher the secret language of babies and young children. Hosted by Simplecast, an AdsWizz company.

Last week, we spoke with psychologist Sheldon Solomon about the fear of death and how it shapes our actions. This week, we pivot from psychology and politics to religion and history as we explore how people have tried to resolve these fears. We talk with philosopher Stephen Cave about the ways we assure ourselves that death is not really the end. Hosted by Simplecast, an AdsWizz company.

Social media sites offer quick and easy ways to share ideas, crack jokes, find old friends. They can make us feel part of something big and wonderful and fast-moving. But the things we post don't go away. And they can come back to haunt us. This week, we explore how one teenager's social media posts destroyed a golden opportunity he'd worked for all his life.

For the last episode in our You 2.0 series, we bring you a favorite conversation with Harvard researcher Dan Gilbert. He explains why we're bad at predicting our future happiness, how that affects our decision making, and why we're actually happier after making a decision that feels irrevocable.

When your phone buzzes or a notification pops up your screen, do you stop what you're doing to look and respond? That's what many of us are doing. Even though we think we should be less distracted by technology, we haven't admitted the true cost of these interruptions. This week, we revisit our 2017 conversation with computer scientist Cal Newport, and consider ways we can all immerse ourselves in more meaningful work. Hosted by Simplecast, an AdsWizz company.

Editor's note, December 6, 2024: Since we first published this episode with Francesca Gino in 2018, other researchers have raised concerns about the integrity of her work. In 2023, a group of scientists publicly alleged that she had fabricated data in some of her studies. You can find more information about their analysis at Data Colada.org. Gino has denied these allegations.A number of Francesca Gino’s studies have been retracted by the journals that published them, including a study about karaoke that is referenced in this episode. Francesca Gino studies rebels — people who practice "positive deviance" and achieve incredible feats of imagination. They know how, and when, to break the rules that should be broken. So how can you activate your own inner non-conformist? This week, we ponder the traits of successful rebels as we revisit our 2018 conversation with Gino. Hosted by Simplecast, an AdsWizz company.

If you live in a big city, you may have noticed new buildings popping up — a high-rise here, a skyscraper there. The concrete jungles that we've built over the past century have allowed millions of us to live in close proximity, and modern economies to flourish. But what have we given up by moving away from the forest environments in which humans first evolved? This week, we revisit our 2018 conversation about the healing power of nature with psychologist Ming Kuo. Hosted by Simplecast, an AdsWizz company.

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, as part of our You 2.0 series, we bring you a favorite 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.

Sometimes when we believe something, we resist data that can change our minds. This week, we look at how we rely on the people we trust to shape what we believe, and why emotions can be more powerful than facts.

At some point in our lives, many of us realize that the way we hear our own voice isn't the way others hear us. This week on Hidden Brain, we look at the relationship between our voices and our identities. Plus, we hear how advances in technology might help people with vocal impairments, and consider the ethical quandaries that arise when we can create personalized, customized voices.

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.

All of us are surrounded by brands. Designer brands. Bargain-shopper brands. Brands for seemingly every demographic slice among us. But have you ever stopped to ask yourself how brands influence you? This week, we look at how companies create a worldview around the products they sell, and then get us to make those products a part of who we are. Hosted by Simplecast, an AdsWizz company.

More than 70,000 people died of drug overdoses in 2017 — many of them from heroin and other opioids. One of the most widely-used tools to confront this crisis is a drug called naloxone. It can reverse an opioid overdose within seconds, and has been hailed by first responders and public health researchers. But in 2018, two economists released a study that suggested naloxone might be leading some users to engage in riskier behavior — and causing more deaths than it saves. This week, we talk with researchers, drug users, and families about the mental calculus of opioid use, and why there's still so much we're struggling to understand about addiction.

Does living with animals really make us healthier? Why do we eat some animals and keep others as pets?

Are women named Virginia more likely to move to Virginia? Are people with the last name of Carpenter more likely to be carpenters? This week on Hidden Brain, we bring you a favorite 2017 episode about our preference for things that remind us of ourselves, and why this tendency can have larger implications than we might at first imagine.

Many of us intuitively feel that the bitter partisanship of American politics is bad for our nation. So should we be concerned about the health of our democracy? This week on Hidden Brain, we revisit two of our favorite conversations about U.S. politics. We start by talking with political scientist John Hibbing about the psychological differences between liberals and conservatives. Then, we explore the role of conflict in democracy with historian David Moss. Hosted by Simplecast, an AdsWizz company.

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. Hosted by Simplecast, an AdsWizz company.

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. Hosted by Simplecast, an AdsWizz company.

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.
