Every day, we leave small traces of ourselves online. And we might not realize what these traces say about us. This week, computational social scientist Sandra Matz explores how understanding what we actually do online ?  not just what we think we do ? can help us improve our lives.

What makes ordinary people do evil things? It was a question that long fascinated the psychologist Philip Zimbardo, who died in October. Zimbardo was best known for the controversial Stanford prison experiment, in which he created a simulated prison in the basement of a university building and recruited volunteers to act as prisoners and guards. This week, we explore how Zimbardo came to create one of psychology's most notorious experiments ? and inadvertently became the poster child for the human weaknesses he was trying to study.

There's a tradition around many Thanksgiving dinner tables that's as consistent as stuffing and pumpkin pie: the family stories that get told year after year. Sometimes these stories are funny; sometimes they make us roll our eyes. No matter how we feel about these tales, we rarely pause to consider how they shape who we are and how we view the world. This week, we talk to psychologist Robyn Fivush about the profound impact that family stories can have on our lives.

Many of us go to great lengths to be happy. But is our singular focus on feeling good actually making us miserable? This week, psychologist Jordi Quoidbach explores what happens when we try to live in an emotional monoculture, and makes a case for letting it all in ? the ups ... and the downs.

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 pride and 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. 

Did you catch last week's conversation about collective emotions? It's the episode in this feed called "Emotions 2.0: When I Feel What You Feel."  

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.

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. 

For more of our You 2.0 series, listen to our episode on how to say no.

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.

You 2.0: Taking Control of Your Time 

Thanks for listening! 

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. 

If you enjoy today's episode, check out last week's kick-off to our series, "You 2.0: The Gift of Other People."

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.

Relationships 2.0: An Antidote to Loneliness

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. 

If you like today's episode, be sure to check out part two of our conversation, exclusively for Hidden Brain+ listeners.

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 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.

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.

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.

You can find all the episodes in our Innovation 2.0 series in this podcast feed, or on our website, hiddenbrain.org. 

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.

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.

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.

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.

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.

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 talk with journalist Steve Inskeep about 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?

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.

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.
