The fight was over a pair of gym shoes. One teenager faces years in prison. The other — the 15-year-old grandson of Congressman Danny Davis — is dead.

We often hear stories about murders sparked by trivial disputes. And we also hear the same solutions proposed year after year: harsher punishments, more gun control.

But what if science can help us find new solutions? Can understanding how we make decisions help us prevent these tragedies?

Few topics send the media into a panic like the idea of hookup culture on college campuses. But are college students actually having more sex than their parents did a generation ago? Research suggests the answer is no.

Lisa Wade, a sociologist at Occidental College, says something has changed, though: In today's hookup culture, developing an emotional attachment to a casual sex partner is one of the biggest breaches of social norms.

This week, we're returning to our archives to grapple with the troubling history of medical experimentation on African Americans and how that history connects to the unequal medical care African Americans still receive today.

President Donald Trump's decision to temporarily ban immigrants from seven Muslim-majority countries and refugees from across the globe has set off a firestorm of protest. In airports and city streets across the U.S. and beyond, people turned out by the thousands over the weekend to protest the action.

Researchers have long been confused by what seems like a paradox: many people in America vote against their economic self-interests. Whether it's the working class conservative who wants a tax cut for the wealthy, or a member of the liberal elite who fights for safety nets that raise his own taxes — we don't always act in the way that would help us the most.

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.

Life often requires improvisation, especially when things don't go according to plan. NPR's social science correspondent Shankar Vedantam brings us the story of one woman who's had to reinvent herself again and again.

So we know that a picture speaks a thousand words, but NPR's Shankar Vedantam is here to tell us how it also gives us really strong impressions of people that we can't seem to shake. Hi, Shankar.

We heard a lot during the presidential campaign about the wage gap, the fact that women often earn less than men for the same kinds of work. Hillary Clinton pushed that issue, and she lost. But it remains a reality in many people's lives.

"Clean up this mess!"

This is a command you've probably given or received in your life. Perhaps in the last day, or even the last hour.

To many of us, the desire to bring order to chaos – to tidy up our kids' toys, organize an overstuffed closet, or rake the leaves covering the lawn – can be nearly irresistible. And it's a desire that extends to other aspects of our lives: Managers tell employees to get organized. Politicians are elected on promises to clean up Washington. And so on.

Many years ago, Simon and Garfunkel interviewed senior citizens and put their voices on an album. One woman in that compilation says...

Every day, Marty Doerschlag moves through the world armed with what amounts to a low-level superpower: He can remember a face forever.

"If I spend about 30 seconds looking at somebody, I will remember their face for years and years and years," he says.

As the mayor of New York City, Rudy Giuliani was a proponent of a controversial policing philosophy known as "broken windows." It calls for police to go after small crimes, in hopes of preventing bigger problems.

At first, it appeared as if violent crime dropped in the neighborhoods where "broken windows" policing was in force. The statistics, however, told a different story.

But the idea remains popular, despite evidence it likely had only modest effects.

The election of Donald Trump came as a shock to many Americans, but perhaps most of all to those in the business of calling elections. The pollsters on both the left and the right had confidently predicted Hillary Clinton would walk away with the race. They got it wrong. But one man did not: Allan Lichtman.

On Sept. 23, Lichtman, a historian at American University, declared that Trump would win, and he stuck by that call through the tumultuous final weeks of the campaign.

In 1969, Philip Zimbardo, a psychologist from Stanford University, ran an interesting field study. He abandoned two cars in two very different places: one in a mostly poor, crime-ridden section of New York City, and the other in a fairly affluent neighborhood of Palo Alto, Calif. Both cars were left without license plates and parked with their hoods up.

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.

It's no secret that this presidential campaign season has been tense, with disagreement and rancor even louder than usual.

Fewer than 1 in 5 members of Congress are women. At Fortune 500 companies, fewer than 1 in 20 CEOs are women. And if you look at all the presidents of the United States through Barack Obama, what are the odds of having 44 presidents who are all men?

If men and women had an equal shot at the White House, the odds of this happening just by chance are about 1 in 18 trillion.
