Biological crime theory describes that an individual is born with the desire to commit a certain crime. Evolutionary factors influence an individual’s involvement in criminal behavior. “Biological theories focus on aspects of the physical body, such as inherited genes, evolutionary factors, brain structures, or the role of hormones in influencing behavior” (Marsh, I, 2006, 3). Murderers that are innate to kill are born with factors such as mental illnesses that are the driving force as to why one may kill. Because of the biological crime theory, some individuals, though rare, are able to plead insanity. This is because the actions of the individual are said to be beyond their control (Ministry of Justice, 2006, 3). There may be a number …show more content…
Cesare Lombroso, medical criminologist, headed the school. Enrico Ferri and Raffaele Garafolo were Lombroso’s disciples, both of whom also headed, as well as had their own opinions on the biological crime theory. Lombroso argued that “criminality was a biological trait found in some human beings” (Boundless, 2015, 1). Today, the biological theory emphasizes the relationship between genetics and crime. The biological theory of crime has evolved over the years in the sense that, initially, the theory was primarily based on physical features. In contrast, it is now primarily based on genetics. As technology has also evolved as well as our knowledge on genetics, this only makes sense (Boundless, …show more content…
Over the years, the theory has evolved into today’s foremost biological crime theory. The theory takes into account genetics and disorders that may be inherited. One example of a disorder that is genetic is antisocial personality disorder. This specific disorder is accompanied by a variety of side effects, some of which may result in psychopathic or sociopathic behavior. Psychopathic and sociopathic behavior specific to this example would be murder. Jeffrey Dahmer, for example, was an individual that participated in seventeen murders over a span of thirteen years. Although Dahmer was not able to plead insanity, he still had a severe mental disorder that may be partly to blame for some of his actions. Biological disorder is often difficult to back up due to the fact that many disorders are also based on nurturing
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.
Crime causation began to be a focus of study in the rapidly developing biological and behavioral sciences during the 19th century. Early biological theories proposed that criminal behavior is rooted in biology and based on inherited traits. Cesare Lombroso (1836-1909), an Italian army prison physician, coined the term “atavism” to describe “the nature of the criminal”...
The media generally portrays the prototypical serial killer through the lens of two extremes. They can either have an incapacitating mental illness or be brilliant, but severely troubled, geniuses. Yet, neither of these two stereotypes are accurate, as serial killers generally display signs of psychopathy, which is not considered a mental illness by the American Psychiatric Association. Despite the erroneousness of Hollywood’s movies and television shows, many psychologists and lawmakers are still considering the degree to which psychopaths can be considered responsible for their actions. In “Psychopathy and Culpability: How Responsible Is the Psychopath for Criminal Wrongdoing?” researchers Adam R. Fox, Trevor H. Kvaran, and Reid Griffith Fontaine attempt to draw conclusions from evidence on whether or not psychopaths meet the criteria for full criminal responsibility. Other researchers, such as Scott E. Culhane, Sage M. Hilstad, Adrienne Greng, and Matt J. Gray, use a case study to demonstrate that psychopathy is not synonymous with serial killers and that mental illness cannot necessarily be used in criminal cases to justify murder in their research paper titled “Self-Reported Psychopathology in a Convicted Serial Killer.” In the remaining two articles
The first well known study of crime and criminals is that of one who is often referred to as the ‘father of criminology’, Cesar Lombroso. Lombroso’s argument was based around the Darwinian theory of human evolution and his theory argued that criminals were a throw back to an earlier period of human progression. In other words, they were less evolved humans, with visible physical features such as large ears and big lips. His theory suggested that criminals were born and not made therefore, where genetically prone to criminality. Merton’s argument was to the contrary.
The most vivid example of the biological determinism is the theory of Cesare Lombroso. Lombroso based his theory on the assumption that criminals have certain physiognomic features or abnormalities. Lombroso wanted to be able to detect future criminals in order to isolate them from the society. This gave criminology a strong push to create new methods of dealing with criminals and prevent crimes. Lombroso implied that prisoners had common facial characteristics. If to exaggerate criminals in Lombroso’s theory can be identified through the shape of their skulls, asymmetry of the face and head, large cheekbones, ears and lips, long arms and a twisted nose. Lombroso’s theory is the oldest one and it can without a doubt be called the main background data for the whole process of the development of criminology. Lombroso stated that men are more inclined to commit crimes due to the conservatism and the narrow-mindedness of their interests. According to Lombroso women have less social contacts and this is what predetermines their conservatism. Thi...
1. There are a couple of differences and similarities between the classical and biological theories of criminology. The biological theories of crime support the idea that an individual commits a crime due to their biological make-up and had criminal tendencies because of certain abnormalities that an individual may have had and not because the offender in their right mind chose to commit the crime. The classical theory has the belief that every individual has their own right in the way in which they act upon, so they commit a crime because they choose to do so, not because it is in their biological make-up.
However as research in to the causes of criminality has developed, we have now come to understand that these aspects of appearance do not contribute to the likelihood of someone becoming criminal. Osborn and West (1979) furthered this study of genetics by comparing the criminality of parents to children and found that the children that had parents with a criminal record have a 40% chance that they will also go on to commit crime (ref). Although this seems to give fairly substantial support the link between genetics and criminality, on the other hand 60% of the children did not go on to commit crime so this study does not have strong support for the criminal gene. Other suggestions have been made that links biology to criminality such as personality traits leading people to be more likely to be come criminal. Hans Eysenck (1977) suggested that individual differences originated in aspects of biology. One example of a personality trait that is used to explain this concept is neuroticism and how this is developed from a difference in arousal levels of the nervous system compared to ‘normal’ people, and this is established in development through childhood (ref). Overall the biological approach does contribute some valuable points to the study of
John Wayne Gacy, Tim Bundy, and Ottis Toole are all infamous serial killers that suffered from a certain disorder. That disorder is called antisocial personality disorder. The biggest question that we have for these men is what triggered these non-empathetic men to commit such heinous crimes, was it mostly biology based or environment? Or do both factors share an equal amount of blame? When it comes to what is the exact cause of antisocial personality disorder, researchers and scientists are unable to come into an agreement. More or less, scientists agree that this personality disorder is caused by a combination of environmental and biological factors. While most scientists are able to agree what environmental conditions serve as precursors for a child to develop antisocial personality disorder characteristics in life, the problem continues to be what internal chemical imbalances are occurring to create this disorder. This ongoing question has been thrown to the public to ponder over for many years. At this time, there are no guarantee of wrong or completely right answers, but only theories to the causation of the disorder. By examining multiple biological theories, along with their fallacies (if any are presented) will we detect what the most probable cause is for this disorder.
In this research paper I will be discussing some of the etiological causes of psychopathy. Causes such as genetic and environment influences on psychopathy
Serial killers have captivated the attention of scientists from the first signs of their existence to modern day. Interested by these killers’ inhumane actions, researchers set out to determine the cause of such graphic, horrific crimes. The brain has been brought into question regarding the motivation of these cold blooded killers. After extensive research, abnormalities of both the chemical composition and material makeup have been identified within the brains of numerous serial killers. These differences are more than mere coincidence, they are evidence that killers do not think in the same way. The killers’ drives and motives are irregular, just as their brains are. Not only are these variations interesting, but they are also crucial to the justice system in regards to the punishment of past, future, and present sequential murderers. It is important that as a society we learn the differences in the mind of a killer, and also recognize and understand them. A serial killer’s brain greatly differs in function from the average citizen’s brain due to physical variations in the brain and a different chemical makeup.
Theories of crime inferred include the biological theory; positivism, atavism and somatotype. Positivism infers that offenses are made due to many factors outside of the offender’s control, making them crime prone (White and Haines, 2000, pp. 36). Atavism believed ‘criminals were biological throwbacks … people more primitive’ (Bernard and Vold et al., 2010, pp. 38). People committing the coward punch ‘don’t ever develop and many are delayed’ and that it is an atavistic feature that is ‘very primitive.’ (Munro, P. 2014, pp. 3) explains Hickie, executive director of the Brain and Mind Research Institute, inferring positivism and atavism. The somatotype theory explains crime is committed by people with muscular builds who enjoy physical activity involving crime. Most criminals are seen as mesomorphs who are muscular, action orientated and aggressive, similar to McNiel’s character who is ‘A labourer with a love of bodybuilding ‘ (Munro, P. 2014, pp. 3).
Ceasare Lombroso is one of the first scholars that developed ideas to explain the reasons why some people behaved more deviant than others or committed crimes. Lombroso conducted research on several prisoners measuring facial features and skull size. He later published a book called “the criminal man in 1876” (Dwyer, 2001 p.15). Lombroso believed that there was two different types of human beings, those who had evolved properly and another which did not. They were more primitive an...
There are various theories within the biological explanation as to why individuals commit criminal behaviour, these include: genetic theory, hereditary theory, psychosis and brain injury theory. In the next few paragraphs examples of each will be shown.
After Comte and Darwin developed their theories about the world, they were followed by several criminologists who also believed that science could answer many of the problems that were present in society, particularly in the field of criminology. One of these men was Cesare Lombroso, who was the first to actually focus on criminology as a science (Adler et al 2012). Lombroso believed criminals could be identified because of physical differences between them and non-criminal members of society (Adler et al 2012). In order to recognize these people he created what he called the "atavistic stigmata" which are characteristics exhibited by humans who were less developed (Adler et al 2012:66). Individuals who exhi...
Theories that are based on biological Factors and criminal behavior have always been slightly ludicrous to me. Biological theories place an excessive emphasis on the idea that individuals are “born badly” with little regard to the many other factors that play a part in this behavior. Criminal behavior may be learned throughout one’s life, but there is not sufficient evidence that proves crime is an inherited trait. In the Born to Be Bad article, Lanier describes the early belief of biological theories as distinctive predispositions that under particular conditions will cause an individual to commit criminal acts. (Lanier, p. 92) Biological criminologists are expected to study the “criminal” rather than the act itself. This goes as far as studying physical features, such as body type, eyes, and the shape or size of one’s head. “Since criminals were less developed, Lombroso felt they could be identified by physical stigmata, or visible physical abnormalities…characteristics as asymmetry of the face; supernumerary nipples, toes, or fingers; enormous jaws; handle-shaped or sensible ears; insensibility to pain; acute sight; and so on.” (Lanier. P. 94). It baffles me that physical features were ever considered a reliable explanation to criminal behavior. To compare one’s features to criminal behavior is not only stereotypical, but also highly unreliable.
