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

Such research cannot, of course, definitively explain the recent case in Cleveland involving Ariel Castro, who has been charged with abducting and raping three women over many years.

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.

In recent months, regulators have launched a series of high-profile arrests 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.

Parents, educators and even public relations flacks have talked at length about the value of coming clean, and there is abundant research on the psychological value of apologizing.

Your Child's Fat, Mine's Fine: Rose-Colored Glasses And The Obesity Epidemic

Shankar Vedantam — Mon, 04 Mar 2013 08:24:00 +0000

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.

Put another way, assuming current trends persist, parents of 80 percent of A

Pig Out In The Winter Or When Money's Tight? Blame Evolution

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.

Evolutionary biologists have long speculated that in prehistoric times, when the blueprint of modern human behavior was created as our ancestors struggled for survival, gluttony may have been a usef

Elite Colleges Struggle To Recruit Smart, Low-Income Kids

Shankar Vedantam — Wed, 09 Jan 2013 08:31:00 +0000

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.

Top schools often offer scholarships that not only include free tuition, but also free room a

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.

In 2005, Florida became the first of nearly two-dozen states to pass a "stand your ground" law that removed the requirement to retreat. If you felt at risk of harm in a park or on the street, you could use lethal force to defend yourself.

Can Skinny Models Undermine Your Dieting Goals?

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.

If I asked you to think of a murderer, what's the image that springs to mind?

If you're like most people, you'll probably think of an evil psychopath, or someone bent on revenge. Perhaps you'll see a criminal mastermind, who eliminates rivals on his way to riches.

Do Orchestras Really Need Conductors?

Shankar Vedantam — Tue, 27 Nov 2012 19:30:00 +0000

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?

A new study aims to answer this question.

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.

Kinkade left a large amount of loose change inside the car each time he dropped it off.

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.
