One of the earliest theories of criminality was Lombroso, who linked physiological features (mostly facial characteristics) to criminal behaviour. Lombroso argued that it is easy to spot criminals as they are not fully evolved, and are more throwbacks to a previous evolutionary state. This is known as atavism. He argued that criminals are born, not made. He argued that criminals have many distinctive characteristics including a large protruding jaw, low sloping forehead, high cheekbones, shifty eyes and fleshy lips and may have tattoos as an indication to a reduced sensitivity to pain. He also stated that different types of crime were committed by different types of criminal, and that these criminals could be distinguished by physical differences.
Goring’s study about physical features of thousands of English prisoners contradicts that of Lombroso as he found none of the distinctive facial characteristics noted by Lombroso. However, he did determine that a common factor amongst criminals were that they were of low intelligence. Since Lombroso’s main claim was that criminality is genetic, and that intelligence is determined by genes, this provides some support.
Overall, there are many limitations to Lombroso’s study as his findings based on the facial measurements of hundreds of criminals, and the skulls of deceased criminals were not compared to a control group of non- criminals. This is a problem as some people who are not criminals may contain some/ all of the above physical features too. Firstly, it is extremely deterministic as it assumes that people are born a criminal due to predisposed factors, and is unable to escape their destiny meaning that it does not take into account social or economic factors. This may raise...

...sues with social desirability and as it is a self report method, there may be a social desirability bias.
A major problem with this theory overall is that there is little evidence to support it. However, Cochrane found links between the psychoticism and neuroticism, but not necessarily on extraversion. Therefore it can be argued that prison time could affect the rates of neuroticism – Thus, causing them to develop a certain type of personality. Again, it is reductionist and it ignores other reasons for crime by solely putting the blame on the individual ignoring things such as the role society (social inequality) and culture plays on crime.
In conclusion, these explanations of crime are simplistic and therefore it is probably better to take an interactionist approach, seeing genes, society, upbringing and personality all interacting to cause criminal behaviour.
The biological approach does not explain all people, what about the people with these characteristics that do not resort to crime, or what about other people who commit crimes who do not possess any of these characteristics. I believe like many criminologists Lombroso was looking for a solution to solve criminal behavior and came up with the theory of physical traits linked to criminal behaviors based on some similarities with no real way to test the theory. I think there are many different reasons why people commit crime, such as opportunity, mental illness, family influence, low economic standing and drug dependence. Theories based on these characteristics in my opinion better describe why people resort to criminal behavior over having certain physical
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.
Criminal behavior can mostly be explained by the Biosocial Branch of Trait Theory. Individual traits by themselves cannot determine criminality. Outside factors such as the environment along with certain personality traits is what causes criminal behavior.
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,
From a sociological perspective, explanation for criminality is found in two levels which are the subculture and the structural explanations. The sociological explanations emphasize aspects of societal arrangements that are external to the actor and compelling. A sociological explanation is concerned with how the structure of a society, institutional practices or its persisting cultural themes affect the conduct of its members. Individual differences are denied or ignored, and the explanation of the overall collective behavior is sought in the patterning of social arrangements that is considered to be both outside the actor and prior to him (Sampson, 1985).
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.
In conclusion, offenders are who they are now by nurture. Although some factors of criminals with biological influences make them more likely to commit crime. However, it can clearly be seen that family and media plays a big role in influencing criminal behaviour in this era where it was proven that when violent acts are frequently observed or thought, it will increase the risk factor on normal people and even more on people with aggressive genes to commit a crime. Therefore, it can be clearly seen that the nurture of the offender outweighs their nature to commit deviant crimes.
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
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.
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.
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...
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.
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...
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.
Different schools of thought propose varying theoretical models of criminality. It is agreeable that criminal behaviour is deep rooted in societies and screams for attention. Biological, Social ecological and psychological model theories are key to helping researchers gain deeper comprehension of criminal behaviour and ways to avert them before they become a menace to society. All these theories put forward a multitude of factors on the outlooks on crime. All these theories have valid relevancy to continuous research on criminal behaviour.
