Shankar Vedantam

Shankar Vedantam is a science correspondent for NPR. The focus of his reporting is on human behavior and the social sciences, and how research in those fields can get listeners to think about the news in unusual and interesting ways.

Before joining NPR in 2011, Vedantam spent 10 years as a reporter at The Washington Post. From 2007 to 2009, he was also a columnist, and wrote the Department of Human Behavior column for the Post. Vedantam writes an occasional column for Slate called "Hidden Brain."

Throughout his career, Vedantam has been recognized with many journalism honors including awards from the Society of Professional Journalists, the Pennsylvania Associated Press Managing Editors, the South Asian Journalists Association, the Asian American Journalists Association, the Pennsylvania Newspaper Association, and the American Public Health Association.

In 2009-2010, Vedantam served as a fellow at the Nieman Foundation for Journalism at Harvard University. He participated in the 2005 Templeton-Cambridge Fellowship on Science and Religion, the 2003-2004 World Health Organization Journalism Fellowship, and the 2002-2003 Rosalynn Carter Mental Health Journalism Fellowship.

Vedantam is the author of the non-fiction book, The Hidden Brain: How our Unconscious Minds Elect Presidents, Control Markets, Wage Wars and Save Our Lives. The book, published in 2010, described how unconscious biases influence people.

Outside of journalism, Vedantam has written fiction and plays. His short story-collection, The Ghosts of Kashmir, was published in 2005. The previous year, the Brick Playhouse in Philadelphia produced his full-length, comedy play, Tom, Dick and Harriet.

Vedantam has served as a lecturer at many academic institutions including Harvard University and Columbia University. In 2010, he completed a two year-term as a senior scholar at the Woodrow Wilson International Center for Scholars in Washington. Since 2006, he has served on the advisory board of the Templeton-Cambridge Fellowships in Science & Religion.

Obstetricians perform more cesarean sections when there are financial incentives to do so, according to a new study that explores links between economic incentives and medical decision-making during childbirth.

Chia-Jung Tsay was something of a piano prodigy. By age 12, she was performing Mendelssohn in concert. At 16, she made her debut at Carnegie Hall. Soon, she was on her way to some of the best music schools in the country — Juilliard and the Peabody Conservatory. And she was throwing her hat in the ring for different competitions.

You don't need to be a social scientist to know there is a gender diversity problem in technology. The tech industry in Silicon Valley and across the nation is overwhelmingly male-dominated.

In the popular imagination and in conventional discourse — especially in the context of highly charged news events such as the shooting of Trayvon Martin — prejudice is all about hatred and animosity.

When students show up at college in the fall, they'll have to deal with new classes, new friends and a new environment. In many cases, they will also have new roommates — and an intriguing new research study suggests this can have important mental health consequences.

As the country awaits two important Supreme Court decisions involving state laws on same-sex marriage, a small but consistent body of research suggests that laws that ban gay marriage — or approve it — can affect the mental health of gay, lesbian and bisexual Americans.

Anthropologists, sociologists and biologists have explored over several decades many factors that shape the likelihood of sexual coercion of women by men.

For some years now, teachers and parents have noted something about boys and girls. Starting in elementary school, young girls often score better on reading and math tests than young boys do.

The differences are uneven on different tests and do not describe the experience of every child, but empirical studies do document a difference.

Now, two economists are proposing a partial explanation for the disparity that might give some parents heartburn.

For years now, psychologists have been telling couples who yell at one another to stop for the sake of the kids. Such conflict in the home — even when no violence is involved — is associated with a host of negative behavioral and life outcomes for children.

Harvard psychologist Mahzarin Banaji was once approached by a reporter for an interview. When Banaji heard the name of the magazine the reporter was writing for, she declined the interview: She didn't think much of the magazine and believed it portrayed research in psychology inaccurately.

But then the reporter said something that made her reconsider, Banaji recalled: "She said, 'You know, I used to be a student at Yale when you were there, and even though I didn't take a course with you, I do remember hearing about your work.' "

In New York and Washington, government regulators are cracking down on insider trading, the illegal practice in which people with internal information about important company events make stock market trades before ordinary investors find out what's happening.

To err is human.

So is refusing to apologize for those errors.

From toddlers and talk show hosts to preteens and presidents, we all know people who have done stupid, silly and evil things, then squared their jaws and told the world they've done nothing wrong.

When Ohio Republican Sen. Rob Portman recently reversed his stance on gay marriage after his son came out as gay, he joined a tidal wave of Americans who have altered their views on the subject.

About 69 percent of American adults are overweight or obese, and more than four in five people say they are worried about obesity as a public health problem.

But a recent poll conducted by NPR, the Robert Wood Johnson Foundation and the Harvard School of Public Health revealed a curious schism in our national attitudes toward obesity: Only one in five kids had a parent who feared the boy or girl would grow up to be overweight as an adult.

Have you ever spent a couple of hours working on a craft project — or a presentation for work — and then fallen in love with what you've accomplished? Do the colors you've picked for your PowerPoint background pop so beautifully that you just have to sit back and admire your own genius?

If so, get in line: You're the latest person to fall victim to the Ikea Effect.

Has the recession made you fat?

To the long and growing list of risk factors known to increase the risk of obesity, scientists recently added a new one: scarcity.

People given subtle cues that they may have to confront harsh conditions in the near future choose to eat higher-calorie food than they might do otherwise, a response that researchers believe is shaped by the long hand of evolution.

In popular lore — movies, books and blogs — criminals who go to prison don't come out reformed. They come out worse.

Across the United States, college administrators are poring over student essays, recommendation letters and SAT scores as they select a freshman class for the fall.

If this is like most years, administrators at top schools such as Harvard and Stanford will try hard to find talented high school students from poor families in a push to increase the socioeconomic diversity on campus and to counter the growing concern that highly selective colleges cater mainly to students from privileged backgrounds.

If a stranger attacks you inside your own home, the law has always permitted you to defend yourself. On the other hand, if an altercation breaks out in public, the law requires you to try to retreat. At least, that's what it used to do.

The millions of Americans who make New Year's resolutions to lose weight often have pictures in mind.

They're pictures that have been repeatedly supplied by the health and beauty magazines at supermarket checkout lines. They feature skinny models in bikinis, or toned guys with six-pack abs, and captions about how you could look like this by summer.

Some people go so far as to tape these pictures onto their refrigerators and cupboards. When they're tempted to reach for a cookie, they reason, the sight of that toned model might dissuade them from breaking their resolutions.

If you're a student at the halfway point of the academic year, and you've just taken stock of your performance, perhaps you have reason to feel proud of yourself.

But a recent study suggests some of the pride you feel at having done well — especially in science — may be unfounded. Or at least your sense of your performance may not be a very accurate picture of how good you actually are.

Have you ever wondered whether music conductors actually influence their orchestras?

They seem important. After all, they're standing in the middle of the stage and waving their hands. But the musicians all have scores before them that tell them what to play. If you took the conductor away, could the orchestra manage on its own?

Some time ago, a man wearing jeans, cowboy boots and a hoodie drove a dirty Ford Explorer into a carwash in Fort Worth, Texas. As soon as the car came back clean, he got it filthy again, and drove to the next carwash. He did this with every single full-service carwash in town.

The man wasn't suffering from a strange mental disorder; Patrick Kinkade was a criminologist conducting an experiment.

In January 2010, more than a year before Mitt Romney had formally announced he was running for president, political historian Allan Lichtman predicted President Obama would be re-elected in 2012.

Vampires and monsters will be out in force tonight, but some of the darkest creatures out there might be your little angels inside those Halloween costumes.

As part of NPR's coverage of this year's presidential election, All Things Considered asked three science reporters to weigh in on the race. The result is a three-part series on the science of leadership. In Part 1, Alix Spiegel looked at the personalities of American presidents. In Part 2, Jon Hamilton examined leadership in the animal kingdom.

At a recent academic conference, Michigan State University professor Natalie Phillips stole a glance around the room. A speaker was talking but the audience was fidgety. Some people were conferring among themselves, or reading notes. One person had dozed off.
