Violent Movies Quell Violence

Counterintuitive, but interesting:

A paper presented by two researchers over the weekend to the annual meeting of the American Economic Association here challenges the conventional wisdom, concluding that violent films prevent violent crime by attracting would-be assailants and keeping them cloistered in darkened, alcohol-free environs.

Instead of fueling up at bars and then roaming around looking for trouble, potential criminals pass the prime hours for mayhem eating popcorn and watching celluloid villains slay in their stead.

"You're taking a lot of violent people off the streets and putting them inside movie theaters," said the lead author of the study, Gordon Dahl, an economist at the University of California, San Diego. "In the short run, if you take away violent movies, you're going to increase violent crime."

Dahl and the paper's other author, Stefano DellaVigna, an economist at the University of California, Berkeley, attach precise numbers to their argument: Over the last decade, they say, the showing of violent films in the U.S. has decreased assaults by an average of about 1,000 a weekend, or 52,000 a year.

..."There are hundreds of studies done by numerous research groups around the world that show that media violence exposure increases aggressive behavior," said Craig A. Anderson, a psychologist and director of the Center for the Study of Violence at Iowa State University. "People learn from every experience in life, and that learning occurs at a very basic level of brain function."

The study's authors acknowledge that their research does not refute and in fact lends credence to the findings of laboratory studies. Neither does it address the long-term effects of exposure to violent media, an influence they view as pernicious.
