An abundance of choices is a good thing, right? In the United States, where choice is often equated with freedom and control, the answer tends to be a resounding 'yes.' But researchers say the relationship between choice and happiness isn't always so clear-cut. This week, we talk with psychologist Sheena Iyengar about making better decisions, and how she's thinking about the relationship between c...

Amidst the confusion and chaos of the COVID-19 pandemic, many of us have sought out a long-trusted lifeline: the local newspaper. Though the value of local journalism is more apparent now than ever, newspapers are not thriving. They're collapsing. For many communities, this means fewer local stories and job losses. But new research suggests there's another consequence that's harder to spot — one t...

Confined to our homes, many of us are experiencing a newfound appreciation for our social relationships. What we may not realize — and what physicians and researchers have only recently started emphasizing — is the importance of these connections to our physical health. This week, we talk with former U.S. Surgeon General Vivek Murthy about why he considers loneliness a matter of public health, and...

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 revisit our 2019 story abo...

We all know people who prefer to follow the rules, and others who prefer to flout them. Psychologist Michele Gelfand defines these two ways of being as "tight" and "loose." She says the tight/loose framework can help us to better understand individuals, businesses, and even nations. This week, we look at the core traits of tight and loose worldviews, and how they may shape our...

A silver lining of social distancing: you may have more time and space to pursue the projects you've bookmarked on your web browser. Whether your goal is to build a barn door or to update your makeup routine, online tutorials have made it easier than ever to bring the world into your living room or kitchen or bedroom. But a curious thing can happen when we watch experts doing expert things. This w...

A virus is more than a biological organism. It's a social organism. It detects fissures in societies and fault lines between communities. Historian Nancy Bristow shares the lessons about human behavior that we can take away from a century-old pandemic. Hosted by Simplecast, an AdsWizz company.

It sounds like a movie plot: police discover the body of a young man who's been murdered. The body tests positive for a deadly infectious disease. Authorities trace the killing to a gang. They race to find the gang members, who may also be incubating the virus. This week on Hidden Brain , we revisit our 2016 story about disease, panic, and how a public health team used psychology to confront an ep...

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 co...

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. Hosted by Simplecast, an AdsWizz company. See pcm.adswizz.com for informatio...

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 AdsW...

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...

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 t...

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. Hoste...

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...

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 . Hosted by Si...

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? Hosted by...

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 th...

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. Hosted by Simplecast, an AdsWizz company. See pcm.adsw...

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...

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. Hosted by Simplecast, an AdsWizz company. See pcm.adswizz.com for informa...

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 diff...

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. Hosted by Simplecast, an AdsWizz company. See pcm.adswizz.com for information about our collection and use of person...

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. Hosted by Simplecast, an AdsWizz company. See pcm.adswizz.com for information about ou...

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. See pcm.adswizz.com...
