In this article, a recent study done by Dr. Barnes, a Florida State University professor claimed that people fell into three categories- persistent offends, adolescence-limited offends (drugs and alcohol, property crime) and abstainers (no deviant behavior). The results of their study showed that genetic factors play a larger role for the life-course offenders compared to the adolescence pathway. I was not surprised by these results because I feel like a lot of people have a deviant stage in their life when they try new things to be rebellious, but this does not mean that they will continue to do these things throughout their life.
In the study by Barnes, they also explained that there is no gene that actually will cause someone to commit a crime because crime is a behavior that one learns. But, there are thousands of genes that will increase your likelihood oh being involved in a crime. I believe that there are genes that cause people to be more likely to be involved in crimes, but I do not think that nature is the only reason for people to be involved in crimes. I am sure that a lot of students here have many of these bad genes, but we do not know it because they have been brought up in an environment that does not involve any crimes. I think people who are persistent offenders have a lot of genes that direct them towards the criminal lifestyle, and they were able to figure this out about themselves because they were brought up in a deviant and criminal environment.
