What causes crime and deviance in society, biological or social factors?

Crime and deviance refer to the breaking of laws and unwritten rules. What counts as criminal and deviant varies over time and between societies, and depends on the social situation in which the act takes place. Deviation is defined as abnormal behaviour from cultures norms, values, or laws so different cultures have different values and norms.  For example it is deviant for women to smoke in Islamic countries but in western society it is normal therefore, deviance is behaviour that is not seen as appropriate and acceptable. It is considered as banned and controlled behaviour which mostly attracts informal social controls such as disapproval, stigmatization and in some cases punishment. On this point sociological research illustrates how a particular form of behaviour may in one situation be classified as deviant and yet in different circumstances may viewed as perfectly accepted, Plummer (1979) stated this point in his distinction between ‘society, and ‘situational’ deviance “Societal deviance refers to those categories of behaviour which are either ‘commonly sensed’ by most members of society to be deviant or deviant dominant beliefs and institutional practices such as law”. (The book)

According to Durkheim, when people act against societal values and norms, then general a system of informal control controls to force them back into conformity for example, disproval and stigmatisation. However, if their behaviour crosses the limit into illegal behaviour, then the formal system of punishment will get involved for instances, police and courts. Durkheim argued that “both the basis and form of punishment changes over time. Crimes are often also enforced by social sanctions. What is deviance is learned through our parents, teachers, media and religion.  Durkheim (1960)

Causes for criminal behaviour are believed to involve both inherited and environmental factors. Genetic causes are linked to chemical imbalances within the brain brought about by gene mutations and which can cause the brain to produce too little serotonin. These mutations aim certain neurotransmitters, or chemicals, that control inhibition and aggression. Dopamine, MAO, serotonin, epinephrine and nor epinephrine are the neurotransmitters affected. Therefore the human body is a chemical factory that must maintain in balance in the brain. Human thoughts, behaviour, and emotions depend upon the programme of electrical impulses within the central nervous system. The gaps between cells in the nervous system are called synapses and the chemicals that enable the flow of electrical impulses across the synapses are called neurotransmitters. Scientists believe that abnormally low levels of neurotransmitters interrupt the flow of electronic impulses, thus short-circuiting emotions such as sympathy or empathy that can inhibit aggressive behaviour. Researchers like Higley (2000) link serotonin to impulsive behaviour “serotonin acts first as a ‘brake’ on a lot of our impulses and people with high levels of serotonin show more restraint and think things through”. They have found a relationship between levels of specific neurotransmitters, such as serotonin, and certain antisocial behaviours, including violence.

To prove this Hans Brunner (1993) studied three male brothers in Holland where one male, criticized by his employer, attempted to run him over with a car, another raped his sister and was sent to mental hospital and the third one coerced his sister into undressing while threatening her with a knife. In this study Brunner discovered “the certain families to be prone to violent outbursts”. Therefore Brunner suggested that low level of serotonin causes aggressive behaviour and concluded in his study. “The family had a lack of serotonin, which may have caused the violent outbursts.
