Chapter 11 Crime
Criminal offenders tend to have lower average IQ scores, around 92, which is eight points below the general population. More serious criminals usually have even lower IQs. This decrease in intelligence is particularly noticeable among young men who are chronic offenders and contribute significantly to overall crime rates. High intelligence can protect individuals from turning to crime, especially those from challenging backgrounds. The document discusses how rising crime rates since the 1960s have deteriorated trust and cooperation within society, which is vital for community life. Most Americans believe crime has increased too much, and while crime statistics have their limits, the rise in reported violent crimes since the 1960s is evident. Despite some debate among experts, there is agreement that the increase in reported crimes reflects a genuine rise in serious offenses.
Depraved or Deprived?
The relationship between crime and the people who commit it can be understood through two main ideas: psychological theories and sociological theories. Sociological theories suggest that criminals are similar to others but are influenced by their social and economic conditions, like poverty and unemployment. These theories often argue that the label of "criminal" is placed on people because of a society that treats them unfairly, which leads to the belief that changes in society are what cause crime rates to rise.
On the other hand, psychological theories focus on the individual traits of criminals. They argue that criminals may have specific psychological or biological characteristics that set them apart, such as lacking a conscience or self-control. Some theories even suggest that some people may be born with a tendency toward criminal behavior.
While social conditions are important in understanding crime, personal characteristics, especially cognitive ability, also play a significant role. Some arguments against the idea that criminals have different psychological traits state that crime rates only change because of shifts in social conditions rather than personal behavior. Others argue that what is considered criminal behavior is defined by society.
However, it is suggested that lower intelligence may be linked to criminal behavior. People with low IQ may find it hard to succeed in school or jobs, making crime seem like a viable option. They might also have difficulty thinking ahead, so they may not consider the risks of getting caught. In summary, those who engage in criminal behavior may differ significantly from the general population when it comes to intelligence and psychological traits.
The Link Between Cognitive Ability and Criminal Behavior: An Overview
There has long been a connection between cognitive ability, or intelligence, and criminal behavior. Early studies showed that many people in prison tended to have lower IQ scores. In the 20th century, researchers like Edwin Sutherland doubted this link, believing that as testing methods improved, differences in intelligence between criminals and noncriminals would disappear. However, this did not happen, and for a long time, many criminologists ignored the role of IQ in crime.
In the late 1970s, researchers Travis Hirschi and Michael Hindelang brought attention back to the connection between intelligence and crime, finding that juvenile delinquents often had lower intelligence levels. Studies showed that people in prison had an average IQ of about 92, which is around 10 points below the average of over 100 for the general population. A large portion of crimes was committed by individuals with lower IQ scores, although those with very low IQs might not be able to commit most crimes or face legal consequences.
Some critics suggested that smarter criminals might avoid arrest, but evidence indicated that the known IQs of offenders accounted for much of the serious crime. Additionally, higher cognitive ability appears to help prevent people from becoming criminals. Studies found that children growing up in difficult situations who had higher IQ scores were less likely to get into trouble compared to those with lower scores. Overall, intelligence seems to be an important factor in understanding why some people commit crimes while others do not.
The Link Between Cognitive Ability and Criminal Behavior: White Men in the Nlsy
The analysis examines how intelligence (IQ) relates to criminal behavior among white males in the United States. It starts by noting that most people who commit crimes are men, and a large portion of those convicted are white males. However, the differences in criminal behavior involve more factors than just IQ, including gender and social backgrounds.
To collect data, interviews were held where the participants shared information about their criminal activities, known as self-report data. This approach helps to capture both crimes that were noticed by the police and those that were not. However, relying on self-reports can be tricky since different racial groups and genders may respond differently. By focusing only on white males, the analysis aims to avoid some of these complications. They also looked at official records, like police stops and convictions, because these are usually reliable indicators of criminal activity.
The results show that only a small number of white males are responsible for most interactions with the police. For instance, just 3% of white males admitted to being stopped by police, making up half of all self-reported stops. Additionally, only 13% have been convicted of a crime, with 2% accounting for half of those convictions. There is a clear link between lower IQ scores and more contact with the criminal justice system. White males who reported never being stopped by police generally had above-average IQ scores, while those with the lowest IQs were more likely to be in jail.
The analysis also reveals that socioeconomic status has little effect on criminal behavior when considering IQ. In fact, a higher socioeconomic status was linked to reporting more crimes, suggesting that lower IQ is a stronger factor in criminal activity than economic background.
Family background is another important aspect. Children from intact families, meaning they live with both biological parents, tended to commit fewer crimes than those from broken homes. However, even with this information, IQ was a more significant predictor of crime than family structure.
Education is crucial as well. Many individuals who engage in serious crimes did not finish high school. Although there is debate about whether dropping out of school causes an increase in crime, research shows that many criminals did not complete their education. The relationship between education, IQ, and criminal behavior highlights the complicated nature of understanding why certain individuals, especially white males in this study, get involved in crime.
Crime, Cognitive Ability, and Conscience
There is a relationship between low IQ and criminality, but most people with low cognitive ability are law-abiding. The rise in crime over the past thirty years cannot be linked to changes in intelligence, but likely stems from other social factors affecting those with low cognitive skills. While socioeconomic disadvantage is often thought to cause crime, data suggest this is not the case. To address crime effectively, focus should shift to managing cognitive disadvantage instead of just poverty and unemployment.
