Teen crime may come from culture, not their brains

Though it has been suggested that spikes in crime rates for teens and young adults in the United States are a result of teens being biologically predisposed to risky, law-breaking behavior, a new study indicates that culture may play a role in shaping the criminal behavior of teenagers.

In a study of age and crime statistics in Taiwan, the researchers say that the Asian country’s youth crime pattern differs from the model seen in most western countries.

“Saying that teen brains are wired for crime has become a mantra, in many ways…”

In the United States, which tends to be more individualistic, for example, involvement in crime tends to peak in middle-to-late teens and then declines, says Darrell Steffensmeier, liberal arts research professor of sociology and criminology at Penn State.

In Taiwan, which has more of a collectivist culture with less separation between generations, however, the crime rate does not dramatically peak at the same ages as it does in the US. Participation in most crimes in Taiwan tends to reach a high point in the late 20s or early 30s, he adds.

Two views

“There is obviously a relationship between age and crime, but, historically, there have been two competing views,” says Steffensmeier.

“The overwhelmingly most acceptable view now is that the age-crime association is invariant. It’s universal—crime peaks in late adolescence and then drops—always and everywhere. But our findings suggest that, in some countries and cultures, the age-crime association is different, so it can’t be invariant,” he explains.

According to the researchers, whose findings appear in the journal Criminology, if crime and age patterns are the same across cultures, that would suggest the age-crime relationship is a preprogrammed behavior driven by biology and neurobiology.

“If it’s universal, then it implies a biological basis,” says Steffensmeier. He says the idea that biology influences the high teen-crime rates may also guide policy making on punishment, crime prevention, and rehabilitation.

“Saying that teen brains are wired for crime has become a mantra, in many ways,” says Steffensmeier. “Some see this as having policy implications, too. For example, if teenagers are pre-programmed for sensation-seeking, which leads to crime, then it means that they’re less responsible and blameworthy. Therefore, people who believe this might say we need to undo this punitive juvenile justice system.

“Now, it may be that the justice system is too punitive, but the idea that this age-crime relationship is driven primarily by biology becomes a scientific rationalization,” he says.

Culture and crime

According to the researchers, the differing patterns between Taiwan and US crime rates suggest that cultural factors may also be important influences on criminal behavior.

“Whatever the biological, or neurobiological, factors that might contribute to criminal behavior, culture and social structure apparently play as great, or greater role,” says Yunmei Lu, a doctoral candidate and graduate assistant in sociology and criminology. “It also suggests a greater amount of plasticity for humans, including during their adolescence.”

In Taiwan, parents are more active in supervising their children, according to Lu. There is also a steep price for nonconforming Taiwan teens.

“In Taiwan, teens are less likely to emphasize autonomy and fun and less likely to engage in behaviors different from, or opposed to, the adults,” says Lu. “Taiwan youth are more likely to view deviance as too risky to their future success in attending a good school or finding a good job.”

Hua Zhong, an associate professor of sociology at the Chinese University of Hong Kong, also worked with Steffensmeier and Lu on the study. She emphasizes that patterns of parental and school involvement in Taiwan may make the country’s age-crime schedule more spread out than in the US for all types of criminal offenses.

Happy teens steer clear of crime, drugs

“In Taiwan, parental and school supervision and involvement are very extensive during adolescence but would be reduced after those children graduated from high school,” she says. “Youth after 18 years old would then have more freedom for exposure to deviant or criminal messages.”

Zhong adds that the age and crime relationship in Taiwan could be linked with its philosophical roots in Confucianism.

According to Zhong, the way societies eventually integrate youth into the world of adults also may play a large role in age-crime patterns.

“Different societies may have differences in age-graded norms and integration of youth with adult society in ways that lead to differences in extent of adolescent crime and the age-crime association,” says Zhong.

The researchers used arrest data from the Taiwan Criminal Investigation Bureau of Police Administration Agency. Data on the US arrests came from the FBI’s Uniform Crime Reporting Program. The researchers examined violent crimes, such as robbery and assault, as well as nonviolent crimes, such as theft and fraud.

Teen’s criminal career can start by age 5

To understand such diversified mechanisms of the age-crime relationship and provide policy suggestions for reducing the high adolescent concentration of criminal offenses in the US, the researchers plan to study age-specific crime data in other countries in order to provide more cross-cultural comparisons.
