Here's how it usually goes: You're working from home and you dial in to a conference call for the morning meeting. Everyone is cheerfully talking around the table. You can't believe what a good time everyone seems to be having, talking about nothing.

Then someone starts to laugh. And then everyone's laughing. Except for you, silently listening on the phone. You're not even cracking a smile, forget about laughing. You wonder, when did this conversation become so hilarious? What am I missing?

A while back, Jonah Berger was talking with a lawyer friend from Washington, D.C. The friend was lamenting the impact of social influence on his peers.

He was saying, "'God, you know, all D.C. lawyers are the same. They make it big, and they go out and they buy a new BMW.'

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 a disaster happens, we want to know, could something have been done to avoid it? Did anyone see this coming?

Many times, the answer is yes. There was a person — or many people — who spotted a looming crisis and tried to warn those in power. So why didn't the warnings lead to action?

In 2012, as a new mom, Maranda Dynda heard a story from her midwife that she couldn't get out of her head. The midwife told her that years earlier, something bad had happened after she vaccinated her son. One minute he was fine, and the next, he was autistic. It was like "the light had left his eyes," Maranda recalled her saying. The midwife implored Maranda to go online and do her own research. So she did.

She started on Google. It led her to Facebook groups, where other moms echoed what the midwife had said.

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.

"Fake news" is a phrase that may seem specific to our particular moment and time in American history.

But Columbia University Professor Andie Tucher says fake news is deeply rooted in American journalism.

In 1690, British officials forced the first newspaper in North America to shut down after it fabricated information. Nineteenth-century newspapers often didn't agree on basic facts. In covering a lurid murder in 1836, two major papers in New York City offered wildly differing perspectives on the case.

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. Annie had beaten some of the best poker players in the world — all men — to get to this point.

But she wasn't sure she deserved to be there.

"I'm sort of thinking, if I fold and I'm wrong, everybody's going to be like, 'See, she plays like a girl, look how he pushed her around,' " said Annie.

OK, so you have just hopped out of an Uber or a Lyft, for example. Let's say the ride has not really gone that well. You pop open the ride-sharing app to give a rating to the driver. You can choose anything from one to five stars. What you do next turns out to be subject to the laws of psychology.

New social science research reveals a bias among many raters that produces pernicious effects. To explain, we are joined by NPR's social science correspondent Shankar Vedantam. Hey, Shankar - pernicious effects.

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.

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."

Bababababa, dadadadada, ahgagaga. Got that?

Babies are speaking to us all the time, but most of us have no clue what they're saying. To us non-babies, it all sounds like charming, mysterious, gobbledegook. To researchers, though, babbling is knowable, predictable, and best of all, teachable. This week, we'll find out how to decipher the vocabulary, and the behavior, of the newest members of the human family.

There are many reasons why the opioid crisis is so hard to confront. One of them is social stigma. It often extends beyond users themselves, to their families.

Hope and Pete Troxell live in Frederick, Maryland. Last year, their 34-year-old daughter Alicia died after overdosing on fentanyl – a synthetic form of heroin. She was seven months pregnant. Hope says before Alicia's death, they often felt the weight of judgment.

"So many people look at these [people] that are addicted to drugs, they call them every name in the book. They're junkies, they're thieves."

The truth can be a tough pill to swallow.

We avoid getting an important medical test done, fearing bad results. We turn off the news when the headlines make us upset, even though the information is pertinent to us.

This behavior, according to economist Joshua Tasoff, is irrational.

"A person should never avoid information, because information can never hurt a decision," he says.

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?"
