Hidden Brain

Sometimes we feel just one single feeling with overwhelming force. We're joyously happy. We're crushingly sad. But sometimes it's more complicated than that: We feel happy and sad at the same time. This week, we revisit a favorite 2022 episode with psychologist Naomi Rothman, who shares her research on the mixed emotion of ambivalence. She explores how being of two minds changes the way we think, and how it changes the way others see us.

For centuries, philosophers and theologians have warned about the dangers of hubris. It’s an emotion that can make us arrogant, egotistical, and reckless. But psychologist Jessica Tracy suggests this caution is too broad. She argues that when we see pride only as a negative emotion, we miss out on all the powerful ways it can also be a driver of creativity, altruism, and accomplishment.

This week, we kick off our new series, Emotions 2.0, with a special double episode about the emotions we experience with other people. We often think that emotions like happiness or sadness live inside our individual minds. But if you've ever gone to a music concert in a big stadium or attended a political rally with like-minded voters, you know that emotions can move through crowds in powerful ways. We begin with psychologist Amit Goldenberg, who studies how emotions spread and ratchet up in intensity as more people experience them. Then, we bring you a favorite 2022 conversation with anthropologist Dimitris Xygalatas, who takes us inside the world of fire walking to explore the emotional power of rituals.

We humans are a social species, and so it's not surprising that we care a lot about what other people think of us. It's also not surprising that many of us stumble when we try to manage others' views of us. This week, organizational psychologist Alison Fragale explains why that is, and offers better ways to win friends and influence people.

I. Me. My. You. He. She. They. It. To. Of. For. These are all words we use without a second thought. But psychologist James Pennebaker says if we pay close attention to the patterns in speech and writing, we can understand profound things about others, and even ourselves.

It can sometimes be exciting when we don't know what's coming next. Other times, the unknown can be deeply troubling. This week, we talk with researcher Dannagal Goldthwaite Young about how we respond to uncertainty, and why this psychological trait plays a surprisingly large role in shaping our behavior, perspectives — even our political beliefs.

Money worries are one of the biggest sources of anxiety in our lives. Psychologist Brad Klontz says these worries are shaped by more than the number in our bank accounts — they’re often driven by our unconscious beliefs. This week, we bring you a favorite 2022 conversation with Klontz, who says it’s possible to identify and change what he calls our “money scripts."

Every morning, you wake up and face the world. What does it look like to you? Do you see a paradise of endless opportunities, where people are friendly and helpful? Or a world filled with injustice, where people cannot be trusted? In the final installment of this year's You 2.0 series, we talk with psychologist Jamil Zaki about how we become disillusioned and distrustful of the world, and how to balance realism with hope.

It happens to the best of us — we blank on someone's name, or forget an important meeting, or bomb a test we thought we'd ace. In this week's installment of our You 2.0 series, we talk to cognitive scientist Daniel Willingham about the mysteries of memory: how it works, why it fails us, and how to build memories that stick.

Saying no to someone who asks for something is often easier said than done. Maybe it's a boss who wants you to take on a new assignment. Or your kid's teacher, seeking volunteers for a field trip. Or a friend who asks you to lend her money. How should we respond to these demands on our time, energy, and resources? This week, psychologist Vanessa Patrick explores why it's so hard to say no, and how we can set boundaries that will make it easier to do so.

Many of us feel like there aren't enough hours in the day. We struggle to make time for all the competing demands at work and at home, and inevitably feel like we're letting someone down. But what if there were a way to reclaim our time and, as a result, get more joy out of our lives? In the second episode of this year's You 2.0 series, psychologist Cassie Mogilner Holmes explains how we've fallen victim to the illusion of time scarcity, and what we can do to spend our time more wisely.

Are you someone who strikes up a conversation with the person next to you on the train? Or do you keep your eyes fixed on your phone? Do you offer gratitude to friends and family? Or do you assume that they already know how you feel? This week, in the kickoff to our annual You 2.0 series, we talk with psychologist Nicholas Epley about our interactions with other people, and how we can make them more rewarding.

Whether in your personal life or at work, you've probably experienced what it’s like to have people reject your requests. To be told that what you want is unfair, or heavy-handed. And you've likely been in the opposite position as well — pushing back against requests that step on your freedom. This week, we talk to psychologist Benjamin Rosenberg about how we respond to infringements on our sense of autonomy, and how we can avoid sparking this resistance in our interactions with other people.

When we meet new people, we’re often drawn to those with a commanding presence or a dazzling personality. But it turns out that a very different trait — humility — is important in the long term. This week, in the first of a two-part discussion, we talk with psychologist Daryl Van Tongeren about different kinds of humility, and how this overlooked quality can play a powerful role in workplace dynamics and romantic relationships.

When we think about misinformation, we often focus on blatant errors or deliberate attempts to deceive us. But in recent years, social scientists have found that misinformation comes in many flavors — many of which are far more subtle than obvious falsehoods. These forms of misinformation prey on our mental blindspots, and take advantage of our passions and loyalties. This week, economist Alex Edmans explores the many insidious forms of misinformation, and how we can all get better at separating fact from fiction.

We're always told to reach for that next ring, work that third job, go to that boisterous party after a long day at work. You only live once ... right? But psychologist Netta Weinstein says that when we constantly engage in achievement and distraction, we lose something essential about ourselves. This week, she makes a case for solitude, and examines what happens when we seek a quieter, more reflective interior life.

As we move through the world, it's easy to imagine we're processing everything that happens around us and then deciding how to respond. But psychologist and neuroscientist Norman Farb says our brains actually navigate the world by coming up with mental maps. These maps act like an autopilot system, allowing us to navigate our lives more efficiently. But sometimes, they can lead us astray, leaving us stuck on a path of negativity and unhappiness. This week, we talk with Norman Farb about how we can update our internal maps and see the world around us more clearly.

Cognitive scientist Nafees Hamid studies the minds of people drawn to radical or fringe ideas. This week, he takes us on a deep dive into the motivations of people on the brink of extremism -- and those who have already been radicalized. We examine what prompts people to turn to violence, and how to pull them back from the seductive appeal of extremist ideas.

You know that negative voice that goes round and round in your head, keeping you up at night? When that negative inner voice gets switched on, it’s hard to think about anything else. Psychologist Ethan Kross has a name for it: chatter. In this favorite conversation from 2022, we talk with Ethan about how to keep our negative emotions from morphing into chatter.

Across every domain of our lives, our minds have a tendency to get accustomed to things. In fact, the brain seems evolutionarily designed to focus on the new and unexpected, on novel threats and opportunities. In our daily lives, this means we take wonderful things for granted. We cease to appreciate amazing people, or the good fortune of being healthy. This week, neuroscientist Tali Sharot explains why we get used to things — and how to see with fresh eyes.

Some think of religious faith as just that: a leap of faith. But psychologists are increasingly filling in the gaps in our understanding of how beliefs shape — and are shaped by — the human mind. This week, psychologist Ara Norenzayan explores features in the brain that are tied to our capacity for faith. And he shows how all of us, both religious and non-religious people, can use this knowledge to find more meaning in our lives.

Have you ever had an unexplainable feeling of emptiness? Life seems perfect - and yet - something is missing. This week, sociologist Corey Keyes helps us understand where feelings of emptiness come from, how to navigate them and why they're more common than we might assume.

Thinking is a human superpower. On a daily basis, thinking and planning and effort bring us innumerable benefits. But like all aspects of human behavior, you can sometimes get too much of a good thing. This week, we talk with philosopher Ted Slingerland about techniques to prevent overthinking, and how we can cultivate the under-appreciated skill of letting go.

The human drive to invent new things has led to pathbreaking achievements in medicine, science and society. But our desire to create can keep us from seeing one of the most powerful paths to progress: subtraction. In a favorite conversation from 2022, engineer Leidy Klotz shares how streamlining and simplifying is sometimes the best path to innovation.

Most of us love to brainstorm with colleagues. But so often, our idea-generating sessions don't lead to anything tangible. Teams fill up walls with sticky notes about creative possibilities and suggestions for improvement, but nothing actually gets implemented. Some researchers even have a name for it: "innovation theater." This week, we explore the science of execution. Psychologist Bob Sutton tells us how to move from innovation theater . . . to actual innovation.

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 continue our Innovation 2.0 series with a 2020 episode about a phenomenon known as as “egocentric bias.” We talk with psychologist Vanessa Bohns about how this bias leads us astray, and how we can use this knowledge to ask for the things we need.

Have you ever been in a situation where you felt that people wrote you off? Maybe a teacher suggested you weren't talented enough to take a certain class, or a boss implied that you didn't have the smarts needed to handle a big project. In the latest in our "Innovation 2.0 series," we talk with Mary Murphy, who studies what she calls "cultures of genius." We'll look at how these cultures can keep people and organizations from thriving, and how we can create environments that better foster our growth.

Why is it so hard to guess where we're meant to be? To predict where we'll end up? Nearly all of us have had the experience of traveling down one road, only to realize it's not the road for us. At the University of Virginia, Saras Sarasvathy uses the lens of entrepreneurship to study how we plan and prepare for the future. We kick off our new "Innovation 2.0" series by talking with Saras about how we pursue goals and make decisions.

If you're a parent or a teacher, you've probably wondered how to balance play and safety for the kids in your care. You don't want to put children in danger, but you also don't want to rob them of the joy of exploration. This week, we talk with psychologist Peter Gray about how this balance has changed — for parents and children alike — and what we can do about it.

We've all had those days when all we want is a little treat. Maybe it's a bag of chips, an ice cream sundae or a glass of wine. But sometimes, these desires become all-consuming. This week on the show, psychiatrist Judson Brewer helps us understand the science of cravings, and how we should respond to them.

Anthropologist Tom Pearson was devastated after his daughter Michaela was diagnosed with Down syndrome. When he began to examine that emotional response, he found himself wrestling with questions that have roiled his field for decades. Early anthropologists would often compare people of different backgrounds and abilities, asking questions like: How is one group different from another? Which one is stronger or smarter? And how do we understand people who don’t fit our expectations? This week, we talk with Pearson about his family’s story, and the evolution of our thinking on disability and difference.

If you've ever taken an economics class, you were probably taught that people are rational. But about 50 years ago, the psychologists Daniel Kahneman and Amos Tversky began to chip away at this basic assumption. In doing so, they transformed our understanding of human behavior. This week, we remember Kahneman, who recently died at the age of 90, by revisiting our 2018 and 2021 conversations with him.

Have you ever sat across from your spouse, colleague or friend and realized that while they may be hearing what you're saying, they aren't actually listening? Poor listening can lead to arguments, hurt feelings, and fractured relationships. But the good news is that active, thoughtful listening can profoundly benefit both people in the conversation. This week on the show, psychologist Guy Itzchakov helps us understand where interactions go awry, and how to become a more attentive listener.

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 revisit a 2019 episode featuring 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.

A little more than a decade ago, researchers began tracking an alarming trend: a dramatic uptick in anxiety and depression among young Americans. Psychologist Jonathan Haidt, like many other researchers, says the increase is related to our use of social media and devices. But he believes it’s also deeper than that — connected to our deepest moral beliefs and how they shape the way we view the world. He says there are simple steps we can take to improve the mental health of kids growing up in the smartphone era.

Fear is a normal and healthy response to things that may harm us. But fear can also hold us back from doing the things we want to do. This week, we talk to psychiatrist and neuroscientist Arash Javanbakht about the psychology of fear — how it helps us, how it hurts us, and what we can do to harness it.

Over the past few weeks, we've been exploring the psychology of partisanship, and how to effectively handle disagreements with those around us. This week, we conclude our US 2.0 series by turning to the past. We’ll explore how one of the most important leaders in American history — Abraham Lincoln — grappled with the pressing moral question of his time. When, if ever, is it worth compromising your own principles for the sake of greater progress?

We typically divide the country into two distinct groups: Democrats and Republicans. But what if the real political divide in our country isn’t between “left” and “right”? What if it’s between those who care intensely about politics, and those who don’t? This week, we bring you a favorite 2020 conversation with political scientist Yanna Krupnikov, who offers an alternative way to understand Americans’ political views.

Conflicts are inevitable — both at a global scale and in our personal lives. This week, in the latest in our US 2.0 series, psychologist Peter Coleman explains how minor disagreements turn into major rifts, and how we can defuse even the most salient of disputes in our lives.

There's a saying that's attributed to the Dalai Lama: in the practice of tolerance, one's enemy is the best teacher. It's a nice idea, but in reality, when people don't share our values, it's hard for us to tolerate theirs. This week, we talk with sociologist Robb Willer about the common mistakes we make in trying to persuade others of our point of view — and how we can break out of our echo chambers.

The United States, we’re told, is increasingly a house divided. Conservatives and progressives are so alienated from each other that conversation is virtually impossible. But are we really as divided as we’re led to believe? As we begin what promises to be a pivotal election season, we're kicking off a new series about how we form our political beliefs. We're calling it "US 2.0." We begin with psychologist Kurt Gray, who studies how we think about our political allies and opponents — and how these insights can help us to chart a new path forward.

We rely on our memory to understand the world. But what if our memories aren't true? This week, we talk to psychologist Elizabeth Loftus about the malleability of memory — what we remember, and what we think we remember.

We spend more and more of our lives staring at screens. Our cellphones, smartwatches and laptops allow us to communicate instantly with people across the globe, and quickly look up obscure facts. But our digital devices are also altering our brains in profound ways. This week, psychologist Gloria Mark explores how our ability to focus is shrinking, and offers ways to protect our minds in a world filled with endless distractions.

Most of us feel that our emotions are reactions to those outside of us. Someone cuts us off in traffic, and we say that the other driver made us upset. A friend brings over food when we're sick, and we say the friend offered us comfort. But psychologist and neuroscientist Lisa Feldman Barrett argues that our feelings are not, in fact, responses to the world — they're really predictions about the world. And she says we can exercise more control over those predictions than we realize.

When we're learning, or trying new things, mistakes are inevitable. Some of these mistakes provide us with valuable information, while others are just harmful. This week, we kick off the new year with researcher Amy Edmondson, who explains the difference between constructive failures and those we should try to avoid.

Humans have wrestled with questions about identity and purpose for millennia. So it’s no surprise that the insights of people who lived hundreds or even thousands of years ago have stood the test of time. This week, philosopher Tamar Gendler explores how three great thinkers from ancient Greece understood the human psyche, and what we can still learn from their wisdom today.

When was the last time you set a goal and struggled to reach it? Perhaps you're trying to write a novel but can't seem to get started. Or maybe you want to master a sport, but you keep making the same mistakes over and over again. This week, organizational psychologist Adam Grant guides us through the science of human potential, and teaches us how to uncover our own abilities.

We like to tell kids, “Don’t judge a book by its cover.” But from a very early age, we humans are doing just that — judging others based on how they look. This week, we bring you the second part of our look at the science of beauty and talk with psychologists Vivian Zayas and Stefanie Johnson about how appearances can often lead us astray.

Think about the last time you were struck by a gorgeous painting in a museum, or heard a song that brought you to tears. All of us know what it’s like to be stopped in our tracks by a beautiful sight. But scientists are still puzzling over why this is the case. What’s the point of beauty? Why is it seemingly so important to us? This week on the show, neuroscientist Anjan Chatterjee explains the function of beauty in our daily lives. Then, Nobel laureate Frank Wilczek describes how beauty served a purpose in some of the biggest scientific breakthroughs of our time.

Why is it so hard to say 'I'm sorry?' In the final episode of our Healing 2.0 series, we talk with psychologist Tyler Okimoto about the mental barriers that keep us from admitting when we've done something wrong, as well as the transformative power of apologies

In 2019, Justin Harrison's mom was diagnosed with terminal cancer. But by the time she died, he had figured out how to keep a part of her alive...forever. This week, the strange and provocative story of a man who believes that grief is not inevitable — that we can, in a way, cheat death.

You've probably heard that people who lose a loved one may go through what are known as the "five stages" of grief: denial, anger, bargaining, depression, and acceptance. But many people find that their grief doesn't follow this model at all. In the latest installment of our Healing 2.0 series, we revisit our 2022 conversation with resilience researcher Lucy Hone. Lucy shares the techniques she learned to cope after a devastating loss in her own life.

We’ve all heard the saying, “What doesn’t kill you makes you stronger.” But is there any truth to this idea? This week, we explore the concept of post-traumatic growth with psychologist Eranda Jayawickreme. He finds that pain can have benefits — but not necessarily the ones we expect.

We all tell stories about ourselves, often without realizing we’re doing so. How we frame those stories can profoundly shape our lives. In the kickoff episode to our month-long series on healing, psychologist Jonathan Adler shares how to tell our stories in ways that enhance our wellbeing.

One of the mysteries of human behavior is that it’s often easier for us to focus on what’s going wrong than on what’s going right in our lives. Why is that? Psychologist Thomas Gilovich studies the barriers that prevent us from feeling gratitude, and how we can overcome them.

As we move through our lives, we have to make decisions both big and small. Some are banal: What will I eat for breakfast today? Should I drive or bike to work? Others are more complicated: How much should I contribute to my 401k? What career should I pursue? Today on the show, behavioral economist Richard Thaler explains why our decision making is often far more nuanced than economic models would suggest.

We like to think that con artists only prey upon the weak, or gullible. But psychologist Dan Simons says all of us can fall victim to scams, because the best scammers know how to take advantage of our biases and blindspots.

Perfectionism is everyone’s favorite flaw. It’s easy to assume that our push to be perfect is what leads to academic, athletic, and professional success. But psychologist Thomas Curran says perfectionism has a dark side, and that there are much healthier ways to strive for excellence.

It's easy to think that the best teams are collections of highly accomplished or talented individuals, working under a skilled leader. But that's no guarantee of success. Psychologist Anita Woolley says the best teams are far more than the sum of their parts, and they share certain basic characteristics.

After we make a decision, we often tell ourselves a story about why our choice was the right one to make. It's a mental process that psychologist Elliot Aronson calls self-justification. These rationalizations can sometimes lead us to excuse bad behavior or talk ourselves out of a poor choice. But are there also times when self-justification can be used for good?

Think about the last time you did something you knew was wrong. How did you explain your actions to yourself? All of us tell stories about why we do the things we do. We justify our failures, and come up with plausible explanations for our actions. This week, Elliot Aronson explains the mental processes behind this type of self-justification, and shares how he helped develop one of the most widely-known concepts in psychology: cognitive dissonance. Humans are full of contradictions. We want to stay healthy, yet we smoke and loathe to exercise. We want to be honest, but we cheat and tell lies. In other words, we want to think of ourselves as good people, yet sometimes we don't act like it. Why is that? This week, psychologist Elliot Aronson shares his research on how we figure out those contradictions.

How often do you say something negative to yourself that you'd never utter to someone else? Self-criticism can often feel like a way to hold ourselves accountable. But psychologist Kristin Neff says there’s a better path to personal growth: self-compassion. In a favorite conversation from 2021, Kristin remembers the painful moment when she learned to show herself self-compassion, and shares how being kind to ourselves can improve our wellbeing and relationships with others.

Sorrows have a way of finding us, no matter how hard we try to avoid them. Joys, on the other hand, are often hard to notice and appreciate. This week, we continue our conversation with psychologist Fred Bryant about the science of savoring, and how to make the most of the good things in our lives.

It’s understandable that we sometimes dwell on things that upset us. But our negative emotions can keep us from savoring the good things in our lives. This week, we continue our You 2.0 series with psychologist Fred Bryant. We’ll discuss the many benefits of savoring, and how we can turn even the smallest of moments into an opportunity for pleasure.

Have you ever set a goal and had a really difficult time sticking to it? Maybe you decide you want to save more money, or go to the gym more often. This week on the show, psychologist Hal Hershfield explains why it can be difficult to set our "future selves" up for success. Plus, he shares tools to help us make commitments that will benefit us in the years to come.

There are times in life when the challenges we face feel insurmountable. Authors succumb to writer's block. Athletes and artists hit a plateau. People of a certain age fall into a midlife crisis. These are all different ways of saying: I'm stuck. This week, in the kickoff to our annual You 2.0 series, psychologist Adam Alter shares his research on why we all get stuck at various points in our lives, and how to break free.

Think about how often you hold back honest opinions of someone else because you don’t want to hurt their feelings. But there are times when this well-intended restraint can be a mistake. This week, in the second part of our series on failure and feedback, psychologist Taya Cohen helps us understand when — and how — to be honest.

No matter who you are, it's guaranteed that at some point in life you'll make a mistake. Many of us find failures to be uncomfortable — so we try our best to ignore them and move on. But what if there was a way to turn that discomfort into an opportunity? This week, we begin a two part mini-series on the psychology of failure and feedback. Psychologist Lauren Eskreis-Winkler teaches us how to stop ignoring our mistakes, and instead, start to learn from them.

This week, we bring you the second part of our conversation on the perils of too much pleasure. Psychiatrist Anna Lembke explains the neuroscience behind compulsive consumption, and how it alters our brains. She also shares techniques she’s learned from her patients to overcome the lure of addictive substances and behaviors.

All of us think we know what addiction looks like: it’s the compulsive consumption of drugs, alcohol, or nicotine. But psychiatrist Anna Lembke argues that this definition is far too narrow — and that a broader understanding of addiction might help us to understand why so many people are anxious and depressed. This week, we begin a two-part series that explains how and why humans are wired to pursue pleasure, and all the ways the modern world tempts us with addictive substances and behaviors.

It's not easy to know how we come across to others, especially when we're meeting people for the first time. Psychologist Erica Boothby says many of us underestimate how much other people actually like us. This week, we revisit one of our most popular episodes to look at how certain social illusions give us a distorted picture of ourselves.

Aging isn’t just a biological process. Our outlooks and emotions also change as we age, often in ways that boost our well-being. Psychologist Laura Carstensen unpacks the science behind this surprising finding, and shares what all of us can learn from older people.

Think about the last time you resisted watching yet another episode of your favorite TV show, or decided not to have a second piece of cake at a friend's birthday party. In many societies, self-discipline is seen as an invaluable trait. But we often overlook what makes it possible to hold back in those moments of temptation. This week, psychologist Celeste Kidd offers a new way to think about self-control. Then, we talk with researcher Jacqueline Rifkin about how to find the right balance between indulgence and restraint.

Determination, hard work and sacrifice are core ingredients in the story of the American dream. But philosopher Jennifer Morton argues there is another, more painful requirement to getting ahead: a willingness to leave family and friends behind. This week, we revisit a favorite 2020 conversation about the ethical costs of upward mobility.

In the second part of our series on the science of meditation, Richard Davidson continues his endeavor to unite seemingly opposite ways of understanding the mind. Plus, he shares the latest research on mindfulness, and the unexpected ways it can benefit us.

In graduate school, neuroscientist Richard Davidson learned to use scientific tools as a way to examine the brain. At the same time, he also started studying under master meditators — who deeply contemplated their internal and external lives. This week, two ways of understanding the mind.

There are plenty of talented people in the world. So why do only a tiny percentage of us reach the highest peaks of achievement? This week, we conclude our "Success 2.0" series by talking with researcher Justin Berg about whether there's a secret recipe for finding — and sustaining — success.

We all have times when we feel like a fraud. In the latest installment of our Success 2.0 series, we revisit a favorite 2021 conversation with psychologist Kevin Cokley. We'll explore the corrosive effects of self-doubt, and how we can turn that negative voice in our heads into an ally.

Think about the last time you tried to bring up an idea at work, and it was shot down. What did you do? Most of us think the best way to win people over is to push harder. But organizational psychologist Loran Nordgren says a more effective approach is to focus on the invisible obstacles to new ideas. In this episode of our Success 2.0 series, we revisit a favorite 2021 interview about overcoming the obstacles that hold back innovation.

We all rely on incentives to get people to do things they might otherwise avoid. Parents reward kids for doing their homework. Companies offer bonuses to their high-performing employees. Charities send gifts to their donors. In the second episode in our "Success 2.0" series, economist Uri Gneezy shares how incentives can help us to achieve our goals, if we know how to avoid their pitfalls.

American culture celebrates those who persevere in the face of adversity. So how do we know when to walk away from something that's not working? Today, we kick off our new "Success 2.0" series with economist John List. He says in every domain of our lives, it's important to know when to pivot to something new.

We all have moments in our lives when we see someone who could use a helping hand. It could be a friend who recently went through a breakup, an elderly person trying to load groceries into their car, or a stranger on the street who looks a little lost. We tell ourselves we should help, but then something stops us. This week, psychologist Amit Kumar helps us understand what keeps us from taking a moment to be kind, and how to overcome these barriers to create stronger, happier connections.

It happens to the best of us — we blank on someone's name, or forget an important meeting, or bomb a test we thought we'd ace. Today on the show, we talk to cognitive scientist Daniel Willingham about the mysteries of memory: How it works, why it fails us, and how to build memories that stick.

It used to be that we tried our best to conceal disadvantages, hardships, and humiliations. But new research explores a curious shift: some people are flaunting limitations that don't exist. This week, we talk to psychologists Karl Aquino and Jillian Jordan about the strange phenomenon of wanting to seem worse off than we really are.

Why do some companies become household names, while others flame out? How do certain memes go viral? And why do some social movements take off and spread, while others fizzle? Today on the show, we revisit a favorite 2021 conversation with sociologist Damon Centola, who studies social contagion and how it can be harnessed to build a better world.

At every stage of life, there are moments when we need buy-in from other people. Yet most of us make a fundamental error when we try to persuade others to see things our way. This week, we talk with Niro Sivanathan of the London Business School about how to make a convincing argument. Then, we learn about what happens to our brains and bodies when we are the recipients of information. Bryan McLaughlin of Texas Tech University shares why it's so hard, but so important, to unplug from the news.

When James and Donovan first met, they knew little about each other, except that Donovan had stolen James' bike. Donovan got caught, and spent a month in jail. It was a story with a happy ending, as far as James was concerned. But then he found out, nearly a decade later, what happened to Donovan after his conviction. This week on the show, we look at the unexpected aftermath of a crime, and what happens when adversaries meet in conversation instead of a courtroom.

Stories help us make sense of the world, and can even help us heal from trauma. They also shape our cultural narratives, for better and for worse. This week, we revisit a favorite 2021 conversation with psychologist Ryan Brown, who explores the phenomenon of “honor culture” and how it dictates our beliefs and behaviors.

In the second part of our series on implicit bias, we explore the relationship between beliefs and behaviors. We also talk with psychologist Mahzarin Banaji about whether research on implicit bias tells us more about groups than it does about individuals.

Would you consider yourself to be prejudiced against people who are different from you? Most of us would say no. But in the late 1990s, researchers created a test to measure biases that may be hidden from our conscious minds. Millions of people have taken it since, and not everyone likes what they've discovered. This week, we launch a two-part look at implicit bias with psychologist Mahzarin Banaji. We ask how is it that we can hold negative stereotypes — without being aware of them.

As you move through the world, it's inevitable that your way of seeing things won't always align with the people around you. Maybe you disagree with the way your neighbor raises her kids, or find your brother's politics to be troubling. But you may not realize how much your core beliefs shape your perception of the world.
