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.
