Many people start exploring their sexuality in college. The lessons they learn about intimacy and attraction during these years lay a foundation for the rest of their lives.

"I have students who have had sex many times drunk but have never held someone's hand," says Occidental University sociologist Lisa Wade.

After you read this sentence, pause for a moment to think back on advertisements you first heard when you were a child.

Perhaps you recall a favorite jingle or the catchphrase of a cereal mascot. You probably can remember more than just one.

This week, we look at the shelf life of commercials. According to University of Arizona researcher Merrie Brucks, an ad we watched when we were five years old can influence our buying behavior when we're 50.

Paul Rozin has been studying the psychology and culture of food for more than 40 years. And he's come to appreciate that food fills many of our needs, but hunger is just one.

"Food is not just nutrition that goes in your mouth or even pleasant sensations that go with it," he says. "It connects to your whole life, and it's really a very important part of performing your culture and experiencing your culture."

Why Now?

Jul 27, 2018

Nearly a quarter century ago, a group of women accused a prominent playwright of sexual misconduct. A Boston newspaper published allegations of sexual harassment, unwanted touching and forced kissing. For the most part, the complaints went nowhere.

In 2017, more women came forward with accusations. This time, people listened.

On this episode of Hidden Brain, we explore the story through the lens of social science and ask, "Why Now?"

If you've ever visited the palm-lined neighborhoods of Beverly Hills, you've probably noticed that the rich and famous aren't the only ones drawn there.

Stargazers also flock to this exclusive enclave, seeking a chance to peer into — and fantasize about — the lives of movie stars and film directors.

Call it adulation, adoration, idolization: we humans are fascinated by glamour and power.

But this turns out to be only one side of our psychology.

Every year, many students who have overcome daunting obstacles in high school receive good news — they've been accepted to college.

These kids represent a success story: through hard work and determination, they've made it into college, and perhaps even on to a better life.

Except it doesn't always work out that way.

After you read this sentence, pause for a moment to think back on advertisements you first heard when you were a child.

Perhaps you recall a favorite jingle or the catchphrase of a cereal mascot. You probably can remember more than just one.

On this week's radio replay, we look at the shelf life of commercials. According to University of Arizona researcher Merrie Brucks, an ad we watched when we were five years old can influence our buying behavior when we're fifty.

People who spend time with young children know firsthand the power of music.

It's easy entertainment.

And any teacher who works in early childhood will tell you that singing can yield amazing results. "If we didn't sing the cleanup song, I don't think anything would have gotten cleaned up," says Laura Cirelli, who worked as an assistant at a day care center in the late 2000s.

But there may be other ways — surprising ways — in which music plays a role in raising a human.

Olutosin Oduwole was in his dorm room at Southern Illinois University when police knocked on his door one day in 2007. They were there to arrest him.

"In my mind I'm thinking, 'Okay, maybe a warrant for a ticket.' I really didn't know what was going on," he says.

What was going on was that the police suspected that Olutosin, a college student and aspiring rapper, was on the brink of committing a Virginia Tech-style mass shooting on his campus. He was soon charged with attempting to make a terrorist threat, and was eventually convicted and sent to prison.

It's one of the darkest chapters in recent history – in 1994, the Hutu-led government of Rwanda led a systematic campaign to wipe out members of the Tutsi minority. At first, the people participating were tied to the government—military leaders, local mayors and police. But soon, thousands of ordinary people were encouraged or bullied into taking part in the killing. Shopkeepers and farmers, fathers and husbands slaughtered their own friends and neighbors, using basic farm tools like hoes and machetes.

This week, we look at the language we use around race and religion, and what it says about the culture we live in.

When we think about dishonesty, we mostly think about the big stuff.

We see big scandals, big lies, and we think to ourselves, I could never do that. We think we're fundamentally different from Bernie Madoff or Tiger Woods.

But behind big lies are a series of small deceptions. Dan Ariely, a professor of psychology and behavioral economics at Duke University, writes about this in his book The Honest Truth about Dishonesty.

Economic theory rests on a simple notion about humans: people are rational. They seek out the best information. They measure costs and benefits, and maximize pleasure and profit. This idea of the rational economic actor has been around for centuries.

But about 50 years ago, two psychologists shattered these assumptions. They showed that people routinely walk away from good money. And they explained why, once we get in a hole, we often keep digging.

Are you racist?

It's a question that makes most of us uncomfortable and defensive.

Harvard University psychologist Mahzarin Banaji says while most people don't feel they're racist, they likely carry unfavorable opinions about people of color — even if they are people of color themselves.

Banaji is one of the creators of the Implicit Association Test, a widely-used tool for measuring a person's implicit biases. She says it's important to acknowledge that the individual mind sits in society.

Envy: it's an unflattering, miserable emotion. And it's universal. All of us, at some time or another, will experience that feeling of wanting what someone else has, and resenting them for having it.

Of course, like all human emotions, envy has a purpose. It's a tool for social comparison, one that can alert us to imbalances in the social hierarchy. Sometimes, these feelings of envy can prompt us to improve our lives, says Harvard social psychologist Mina Cikara.

"If you have more than what I have, I may be inspired by what you have," she says.

What are the lives of the planet's wealthiest people really like?

Several years ago, sociologist Brooke Harrington decided to find out.

She knew she'd have a hard time gaining access to the world of the über wealthy, so she did something unusual: She took courses to become a wealth manager.

In the course of this training, Harrington met other wealth managers, who agreed to be interviewed for her research.

She discovered that, in order to manage money for the super-rich, these professionals learn a lot about the private lives of their clients.

No one will deny that marriage is hard. In fact, there's evidence it's getting even harder.

Eli Finkel, a social psychologist at Northwestern University, argues that's because our expectations of marriage have increased dramatically in recent decades.

"[A] marriage that would have been acceptable to us in the 1950s is a disappointment to us today because of those high expectations," he says.

Our airwaves are filled with debates about immigrants and refugees. Who should be in the United States, who shouldn't, and who should decide?

These modern debates often draw upon our ideas about past waves of immigration. We sometimes assume that earlier generations of newcomers quickly learned English and integrated into American society. But historian Maria Cristina Garcia says these ideas are often false.

In 2006, Derek Amato suffered a major concussion from diving into a shallow swimming pool. When he woke up in the hospital, he was different. He discovered he was really good a playing piano.

It may sound like the plot of a movie: police find a young man dead with stab wounds. Tests quickly show he'd had Ebola.

Officials realize the suspects in the case, men in a local gang, may have picked up and spread Ebola across the slum. These men are reluctant to quarantine themselves and some – including a man nicknamed "Time Bomb" – cannot even be found.

This scenario actually unfolded in the West African country of Liberia in 2015. And what followed was a truly unconventional effort by epidemiologists to stop a new Ebola outbreak.

President Trump has talked an awful lot about fake news this past year, and it's not just the president. Other Republicans use this term. Democrats use it. It has become an increasingly partisan phrase. Don't like something? Call it fake news. Social science research explores how our minds actually push away information that gets in the way of our feelings and desires. NPR social science correspondent Shankar Vedantam talked with our own David Greene about this.
