A study suggests that lifelong criminals could be genetically programmed to break the law. Carried out by the University of Texas and recently published in the Criminology journal the study suggests that crime can be in part genetic. Researchers looked at 3 groups of people, those who offend throughout their lives, those who only commit crimes in their teens and those who always obey the law. They focused on the persistent offenders and found that whilst adolescent offenders were more influenced by their environment, the same was not true of those who became lifelong criminals. Ultimately the findings suggested that up to 70% of our chance of lifelong criminality could be genetic.
