President Trump said this week that a few "bad apples" were to blame for police killings of black people. But research suggests that something more complicated is at play — a force that affects everyone in the culture, not just police officers. In this bonus episode, we revisit our 2017 look at implicit bias and how a culture of racism can infect us all.

We don't always behave the way economic models say we will. We don't save enough for retirement. We give money to charity. This week, why we act in ways that go against our "rational" self-interest.

Are women named Virginia more likely to move to Virginia? Are people with the last name of Carpenter more likely to be carpenters? This week on Hidden Brain, we bring you a favorite 2017 episode about our preference for things that remind us of ourselves, and why this tendency can have larger implications than we might at first imagine.

Many of us intuitively feel that the bitter partisanship of American politics is bad for our nation. So should we be concerned about the health of our democracy? This week on Hidden Brain, we revisit two of our favorite conversations about U.S. politics. We start by talking with political scientist John Hibbing about the psychological differences between liberals and conservatives. Then, we explore the role of conflict in democracy with historian David Moss.

Sometimes, when we believe something, no amount of data can change our minds. This week, why we cling to our beliefs — even when they're wrong.

Annie Duke was about to win $2 million. It was 2004, and she was at the final hand of the World Series of Poker Tournament of Champions. But as a woman at a table full of men, she wasn't sure she deserved to be there. In this week's Radio Replay, we tell the stories of two people who grappled with gender stereotypes on the job. Annie Duke shares her experiencing at the World Series of Poker, and then we hear the story of Robert Vaughan, a former Navy sailor who decided to pursue a new career as a nurse.

What happens when we connect with people whose view of the world is very different from our own?

The turn of the year is a time when we set the old aside and welcomed the new into our lives. When one chapter ends, another begins.

The adage "be kind to others" is simple enough that even young children can understand it. But that doesn't mean adults always remember the importance of being kind or understand how compassion might affect them. This week, we look at the science of compassion, and why doing good things for others can make a big difference in your own life.

Arguments and bickering can sour family gatherings during the holiday season. This week, we share tips on how to avoid miscommunication from our January 2018 conversation with actor Alan Alda. You might know him from his roles on television shows like M*A*S*H, The West Wing and 30 Rock, but in recent years Alda has also focused on helping scientists, and the rest of us, communicate better. His book is If I Understood You, Would I Have This Look on My Face? My Adventures in the Art and Science of Relating and Communicating.

We all know the downsides of being poor. But what about the downsides of being rich? This week, we explore the psychology of scarcity...and excess.

Nearly a quarter century ago, a group of women accused a prominent playwright of sexual misconduct. For the most part, the allegations went nowhere. In 2017, in the midst of the #MeToo movement, more women came forward to accuse the same playwright of misconduct. This time, everyone listened. On this episode — originally broadcast in February 2018 — we explore the story through the lens of social science research and ask, "Why Now?" What has changed in our minds and in our culture so that allegations of sexual harassment and assault are being taken more seriously than they were in the past? A note: This story includes descriptions of sexual harassment and assault. It may not be suitable for all listeners.
