Adrian Raine’s article “The Criminal Mind” has been buried in a pile of must-reads on my nightstand for months now. When it was first published in April 2013 in The Wall Street Journal, I was too busy with the release of my book. And frankly, I was also a bit afraid. Last night, though, I finally unearthed the article and read it.
Of course I knew from my own research that neurocriminology receives far more funding than environmental psychology of violent behavior, but I’ve always been wary of it. I thought that to look at the brain as the cause of criminal behavior was misleading and dangerous. Why? Crime and incarceration affect a disproportionate number of people of color. The conclusion that the make-up of one’s brain causes a person to become a criminal may suggest to some that African Americans are by nature more violent than white people. It would bring us precariously close to the 19th-century pseudoscience of Phrenology, which claimed that we could recognize a criminal by his physical features. Furthermore, I was—and still am—worried that the increasing focus on the physical traits of criminals lessens our interest in crime-causing factors in the environment, factors that can potentially be changed. We can fight poverty, the easy accessibility of guns, bad schools and a dysfunctional family background, but our brains? Good luck with that! I also wish society would take at least some responsibility for people’s actions.
Raine’s article, however, does justice to the complexity of the issue. A Professor of Criminology, Psychiatry and Psychology at the University of Pennsylvania and the author of The Anatomy of Violence (Pantheon, 2013), Raine concludes that “genetics and environment work together to encourage violent behavior.” A child who is predisposed to violent behavior due to his genetics does not necessarily become a criminal; there are plenty of environmental factors that can make up for neurological “handicaps.” Proper nutrition may play a role, for example: Raine writes that studies have shown that Omega-3 supplements in the diets of young offenders reduces serious offending by about 35%. And even if a child’s brain doesn’t show any abnormalities at birth, exposure to environmental toxins, physical abuse and emotional deprivation—a lack of love and a supportive social environment—may alter his brain chemistry, causing him to commit acts of violence. As a result, an initially healthy brain can turn into one that causes impulsiveness, a trait that has long been recognized as a leading cause of violent behavior. Lead is neurotoxic, according to Raine, damaging the prefrontal region which regulates behavior. “Rising lead levels in the U.S. from 1950 through the 1970s neatly track increases in violence 20 years later, from the ’70s through the ’90s.” He concludes, “No other single factor can account for both the inexplicable rise in violence in the U.S. until 1993 and the precipitous drop since then.” Continue reading
