• What Are The Odds?

  Coincidences can feel like magic. When we realize that a co-worker shares our birthday or run into a college roommate while on vacation, it can give us a surge of delight. Today, we revisit a favorite episode about these moments of serendipity. Mathematician Joseph Mazur explains why coincidences aren't as unlikely as we think they are, and psychologist Nicholas Epley tells us why we can't help but find meaning in them anyway.

• Tribes and Traitors

  In the past weeks, headlines around the world have focused on the violent conflict between Israelis and Palestinians. In this favorite episode from our archive, we hear from a former Israeli soldier and a Palestinian man who asked a radical question: what happens when you empathize with your enemy?  They found that showing such empathy can be powerful — but also carries risks.  If you like our work, please consider supporting it!

• Josh Gitelson: My Unsung Hero

  At the end of every episode, we take a moment to thank an Unsung Hero: someone who’s not on the staff of the show, but who went above and beyond in helping us out. In recent weeks, we've been asking you to share your own examples of someone who's made an impact on your life. This time, Josh Gitelson of State College, Pa., recalls a small gesture of kindness from a stranger on a plane. Do you have a story of an unsung hero you want to share with our listeners? Tell us about it! Please email us at ideas@hiddenbrain.org, with the subject line "Unsung Hero." For some guidelines on what we're looking for, go to hiddenbrain.org/unsunghero.

• One Head, Two Brains

  Your brain is divided in two: a left hemisphere and a right hemisphere. In this 2019 episode of Hidden Brain, we dive into Iain McGilchrist's research on how the left and right hemispheres shape our perceptions. Iain argues that differences in the brain — and Western society's preference for what one hemisphere has to offer — have had enormous effects on our lives.

• Humor Us

  Hahaha! The average four-year-old child laughs 300 times a day. By contrast, it takes more than two months for the average 40-year-old adult to laugh that many times. This week, we talk with behavioral scientist Jennifer Aaker of Stanford University about why so many of us fall off a “humor cliff” as we become adults. Plus, how we can inject more laughter into our lives, even during the most difficult of times.

• An Unfinished Lesson

  More than a century ago, millions of people around the world died in a massive influenza pandemic. The so-called "Spanish flu" outbreak of 1918 revealed a truth about viruses: they don't just infect us biologically. They also detect fissures in societies and fault lines between communities. Historian Nancy Bristow says this remains true today, as we continue to grapple with the COVID-19 pandemic.This week, we revisit our 2020 conversation with Bristow, and consider what history can tell us about human behavior during public health crises.

• Useful Delusions

  Podcast hosts are used to being the ones asking the questions. This week, though, we’re going to flip that script, and put Shankar in the guest seat. We’ll hear a recent interview he did with Krys Boyd of the public radio show Think from KERA in Dallas. The discussion revolves around Shankar's latest book, Useful Delusions, and how self-deceptions can bind together marriages, communities, and even entire nations.

• Made of Honor

  Stories help us make sense of the world, and can even help us to heal from trauma. They also shape our cultural narratives, for better and for worse. This week on Hidden Brain, we conclude our three-part series on storytelling with a look at the phenomenon of "honor culture," and how it dictates the way we think and behave.

• The Story of Your Life

  We can’t go back and change the past. We can’t erase trauma and hardship. But what if there was a way to regain control of our personal narratives? In the second part of our series on storytelling, we look at how interpreting the stories of our lives — and rewriting them — can change us forever. Also, a note that this week's episode touches on themes of trauma and suicide. If you or someone you know may be having thoughts of suicide, please call or text the National Suicide Prevention Lifeline at 1-800-273-8255.

• The Story of Stories

  Why is my friend late? How does nuclear fission work? What occurs when I sneeze? We all need to understand why certain things happen. Some researchers think the drive to explain the world is a basic human impulse, similar to thirst or hunger. This week on Hidden Brain, we begin a three part series on why we tell stories. Psychologist Tania Lombrozo discusses how explanations can lead to discovery, delight, and disaster.

• Radically Normal

  For generations, it was difficult, even dangerous, to express a sexual orientation other than heterosexuality in the United States. But in recent years, much has changed. This week, we revisit our 2019 episode about one of the most striking transformations of public attitude ever recorded. And we consider whether the strategies used by the LGBTQ community hold lessons for other groups seeking change.

  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?
