There are many factors that are utilized to explain crime. These include things such as DNA, environmental contaminants, hormones, nutrition, and body chemistry can all play a role in criminal behavior and all of these determinants can be passed down through generations making human behavior determined by genetics to some degree. Violent behaviors have been linked to nutrition, vitamin deficiency and other conditions that affect the body. Body chemistry theories have all contributed to advances in understanding criminal behavior. Many studies have been done to link violence with body chemistry. One of those being a link between murder and low blood sugar. In cases where the body produces too much insulin it was noted that the mind's capacity

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 first subcategory is called the “Biochemical factor”, which is believed by some criminologists that there is a direct link between crime and anti-social behavior caused by environmental factors that affect a person’s internal biochemistry. (Siegel & Worrall, 2013, pg. 45)
What makes one person more likely to commit crime than another? Many people have worked throughout the years to try and answer this question in an attempt to really get to the root cause of crime so that things can be done to better prevent it. One major school of thought centering around this question is based on trait theory. This theory focuses on the hypothesis that some people have certain personality traits or genetic predispositions that make them more likely to commit crime than someone without these factors. Other things that may come into play regarding trait theory and predisposition to crime are the individual's parents and the environment they were raised in.
Despite much controversy surrounding the notion of inherited criminal tendencies, there is much evidence to support such theories. Although Lombroso may have employed his theoretic atavisms in an attempt to provide a biologically deterministic method of reducing or preventing crime, they have ultimately lead to an abandonment of gravitas concerning such a notion. However, as myopic as Lombroso's theories of criminality being a hereditary trait appears (Mannheim, 1965) research has shown shared physical characteristics to be commonplace in explicating the argument of genetic criminal behaviour. Although Lombroso presented...
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...
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.
1. Cesare Lombroso applied the methods of natural science (observation, measurement, experimentation, statistical analysis) to the study of criminal behavior. Lombroso rejected the classical theory of crime, associated with Cesare Beccaria and Jeremy Bentham, which explained criminal activity as freely chosen behavior based on the rational calculation of benefit and loss, pleasure and pain. Critically analyze both schools of thought and provide an opinion as to what theory you believe is more relevant.
In this article the two authors research the connection between genetic factors and criminal behavior. They look at the causes that make someone act in a criminal way. There are several factors looked at in connection to the cause such as social factors and environmental variables. The social factors being the more examined of the two. They hypothesized that other factors in performance or alone with environmental variables would lead to better understanding of why some people become criminal. The genetic factor of influence due to mental disorders was posed to have a slight role in affecting people to show criminal behavior. Another cause looked at was the combination of genetic and environmental factors, with a possible result of having a higher risk for criminal behavior.
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.
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.
Behavioral theory of criminology as defined by Cesare Lombroso is a theory that criminals were born genetically and they have the specific physical (Theories of the Causes of Crime, 2009). Another researcher William Sheldon proposed a theory that body shape can contribute as a factor to influence people to engage in crime. She suggested that muscular and athletic people are more likely to commit crime because these people have better posture, high muscle mass and thick skin (Crossman, 2015). Biological explanation before the 1960s focuses on the causes of crime throughout the exploration on the characteristics of the physical body, genital, evolutionary factors, mind structures, or the hormones (Theories of the Causes of Crime, 2009). In the modern century, researchers propose that areas to be studied are genetic transmissions and physiology, they can serve as factors regard to criminal behavior.
Human antisocial behaviour is complex and trying to understand it has always proven to be a daunting intelligent task, especially in modern culturally diverse societies. Crime, broadly defined as behaviour through which individuals obtain resources for others through uncouth means, presents as one of the most refractory internal social dilemmas. Understanding individual criminal acts such a murder, rape or motives behind them is intricate, rather their behavioral definitions and causes offers a more clear platform for argumentative reasoning. Criminal behaviour, regardless of manner, involves use of barbaric methodologies to obtain symbolic or material resources. Criminal behavior results from methodical processes that involve intricate interactions among isolated, societal, and environmental factors in people’s lives.
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.
