There has been reason that genes have been the cause of criminal behavior. Recently there has been many studies that:
“Recent studies in behavioral genetics indicate that some violent criminals are genetically predisposed to violent behavior. One study has found that a mutation in the structural gene for monoamine oxidase A gives rise to an acute build-up of neurotransmitters associated with the body’s ‘fight or flight’ responses to stressful situations (Evansburg 2001)” (Wilson).
Also, another study showed that: “focused on whether genes are likely to cause a person to become a life-course persistent offender, which is characterized by antisocial behavior during childhood that can later progress to violent or serious criminal acts later in life.” (Barnes). What these studies indicate is that criminologists are trying to see if genes contribute to people becoming criminals.
Another study took twins and monitored their behavior in different situations. This study showed: “comparing monozygotic (MZ) or identical twins and their rates of criminal behavior with the ra...

Nature vs. nurture has been one of the oldest and most debated topics among psychologists over the years. This concept discusses whether a child is born into this world with their developmental work cut out for them or if a child is a “blank slate” and their experiences are what shape them into who they are. Over the years and plenty of research, psychologists have all mostly come to agree that it’s a little bit of both. Children are both born with some genetic predispositions while other aspects of the child’s development are strongly influenced by their surrounding environment. This plays into the criminal justice system when discussing where criminal behavior stems from. Is a criminal’s anti-social behavior just part of their DNA or is it a result of their upbringing? The answer to this question is not definite. Looking at research a strong argument can be made that criminals developed their anti-social patterns through the atmosphere in which they were raise, not their DNA.
Due to an increased surge of criminality in many cities during the 1900s, eugenicists began to focus on the role of genes in determining criminal behavior. Many lived by the motto “culture does not make the man, but man makes the culture.” This essentially stated that the less fortunate tend to create and gravitate towards poverty stricken environments. While scientists did not totally weigh out the environmental influence on criminality, they did believe the main cause of criminal behavior was defective genes.
Trait theory views criminality as a product of abnormal biological or psychological traits. It is based on a mix between biological factors and environmental factors. Certain traits alone cannot determine criminality. We are born with certain traits and these traits along with certain environmental factors can cause criminality (Siegel, 2013). According to (Siegel, 2013), the study of sociobiology sparked interest in biological or genetic makeup as an explanation for crime and delinquency. The thought is that biological or genetic makeup controls human behavior, and if this is true, then it should also be responsible for determining whether a person chooses crime or conventional behavior. This theory is referred to as trait theory (Siegel, 2013). According to Siegel (2013), due to the fact that offenders are different, one cannot pinpoint causality to crime to just a single biological or psychological attribute. Trait theorist looks at personal traits like intelligence, personality, and chemical and genetic makeup; and environmental factors, such as family life, educational attainment, economic factors, and neighborhood conditions (Siegel, 2013). There are the Biosocial Trait theories an...
Nature versus nurture has been argued in attempt to understand how criminals behave. The theory of what influences psychopath and serial killers’ violent and destructive pathways has not been agreed on till this day. Criminals such as psychopaths and serial killers have been researched for the past two decades. Scientists have found that genetics is a determining factor of who becomes a serial killer. It is important to understand the determinants involved within a serial killer, because if these social and environmental causes are discovered, they can be altered and controlled to reduce crime (Lykken, 1993). With more studies, we would therefore prevent mass murders and could assist in significant reductions of crime within society.
It is believed that genes may be playing a role in criminal behavior. There are beginning to have arguments whether if people are destined for a life of a crime. Scientists in the Netherlands after studying a particular family identified a specific gene mutation that resulted in a chemical imbalance in the brains of some of the males in the family, with this being said it could explain why the same men were prone to violent outbursts (Connor).
I also see that the scholars “underestimate the resiliency of the criminal justice system,” and that this evidence cannot be completely denied. Since I cannot effectively argue properly researched science I would have to stay that some are possibly prone to criminal behavior for genetic reasons but on a minority. From my standpoint I would have to agree with Jones’s conclusion that the criminal justice system will neither crumble from nor ignore the new genetic research but rather integrate it on some level in its
Both environmental and genetic factors have been questioned. Genetic factors have been suspected since the incidence of antisocial behaviour is higher in people with an antisocial biological parent. The environment is also contributes to the factor of antisocial behaviour. Studies have shown that a person whose role model had antisocial behaviour, is more than likely to develop the same behavour. According to Psychology Today (2017) Approximately 3 percent of men and one percent of women have antisocial personality disorder. A much higher percentage exist among the prison population.
It is a fact that criminals have a smaller brains than law abiding citizens. Often, offenders share particular physical traits such as, being young males, muscular, having lower than average IQ, and a impulsive personality. Serial offenders are usually hyperactive and difficult children If a person has a low IQ, it is proven to be directly related to their tendency to be commit impulse actions that provide an immediate payoff. For instance, a rape or a mugging would provide a criminal with an immediate payoff. It is proven that crime often runs in families. In fact, chronic criminals are proven to be three times more likely to have criminal children. However, despite this information, scientists have no basis to come to any conclusions with this data. Therefore, one must consider other possible factors that may create a criminal mind, to come to a reasonable decision as to how one is developed.
Boutwell found through “Analysis of the Add Health data revealed that exposure to drug-using peers and levels of self-control were associated with abstention from” criminal behavior (Boutwell). As well as “multifactorial arrangement of environmental and genetic factors contributes to delinquency abstention.” (Boutwell). Boutwell’s study supports what Watts and McNulty found in their analysis of the biological and social effects on adolescents and criminal behavior. Watts and McNulty’s study shows the effect of biology and our genetic make up compared to our socialization and likelihood to associate with different peer groups. The findings tell us that both biology and socialization have an effect on the criminality of an individual. The biological implications argue
They also explore the myths about the connection between genetic factors and criminal behavior. The first myth they looked at was “Identifying the Role of Genetics in Criminal Behavior Implies That There Is a “Crime Gene.”” This myth is dismissed because of the unlikelihood that that a single gene is responsible for criminal behavior. The second myth they look at is “Attributing Crime to Genetic Factors is Deterministic.” This myth is also easily dismissed because of the fact that just because someone has a predisposition to a certain behavior doesn’t mean that the person will take on that behavior.
... 86). Hence why I believe that criminal behaviour is influenced by mixture of a persons social background, life chances and pathology
There are more contemporary biological theories that have since developed. However, most are still nearly impossible to prove true; for example, the genetic theory of crime in fraternal and identical twins. This study is supposed to provide evidence that those who are born with the same genetically heritable trait are more prone to crime than fraternal twins or siblings because of the ...

Criminality constitutes strategic mannerisms characterized by apathy to misery inflicted on others, egocentricity and depressed self-control. Habitual criminal behaviour seeks to satisfy the offender’s desires for material prestige, power or pleasurable feelings regardless to damage inflicted to victim or society. Such behaviors extend mistrust, fuel prejudice, and largely corrupt social cohesion. Biological, psychological and environmental attributes are thought to heavily influence antisocial and criminal behaviour. Numerous studies have proven that active emulation, genetic predispositions and psychosocial labeling are all complementary to development and expressions of criminal behaviour. There has historically been a myriad of theories that attempt to explain criminal behaviour through different perspectives, all which constitute intricate paradigms that play a role in expressio...
