Positivist School Of Criminology Case Study

Decent Essays
The biological theory of criminology is based upon the idea that offenders within the criminal justice system are genetically and physiologically different from those who are non-offenders. This theory was founded by Ceasere Lombroso who said that an individual was ultimately born to be a criminal, or that a person inherited certain traits that made them more susceptible to engage in violent behaviors. Moreover, Lombroso rejected the Classical School of Criminology, which claimed that people have their own free will towards making certain decisions. Lombroso represented the Positivist School of Criminology, which utilizes scientific analysis and research as a means of describing criminal behavior. Since the introduction of the Positivist School, …show more content…
Additionally, Tihonnen et. al (2015) wanted to associate further genes by examining HTR2B (a protein coding gene that is responsible for certain heart-related diseases). Tihonnen et al. (2015) examined two different cohort categories including: Crime and the Healthy cohorts. Within the Crime cohort, all of the subjects came from 19 various prisons around Finland (n=794 inmates) and there were three groups that stemmed from it including: non-violent offenders (n=215), violent offenders (n=538), and extremely violent offenders (n=84). To be considered a “non-violent” offender the individuals had to engage in crimes such as drunk driving or drug charges to land themselves in prison; whereas, “violent” criminals had to commit only one act of murder, manslaughter, homicide, battery, etc. and “extremely violent” offenders had more than 10 counts of these acts on their records. Additionally, it was calculated that the 84 offenders in the extremely violent cohort had committed a total of 1154 attempted murders, homicides, or battery charges (M=13, range- …show more content…
(2004) was able to discover a difference between offenders and the control groups (p=.01) with the offenders having 14% lower mean activity at the MAO gene. Furthermore, there was no significant difference found between the prison personnel and the healthy persons not associated with any sort of prison environment. With this, the researchers were able to merge the prison personnel and the healthy individuals into one control group that served as a comparison against the offenders. Also, they did several tests among all of the subjects including Impulse Control, Past Feelings and Acts of Violence, and the Suicide Risk Scales. Skondra et al. (2004) determined there to be no significant correlation between these scales and MAO

    Trait theory is a theory originated by Italian criminologist and physician, founder of the Italian School of Positivist Criminology Cesare Lombroso. Lombroso rejected the classical theory of crime, according to Cesare Beccaria who stated that all crime is rational and that criminals analyze all factors of the crime before committing the act. According to Cesare Lombroso’s, he concludes that crime is not rational but is predisposed by genetic factors which renders criminals the inability to control their actions. According to the trait theory, criminals are products of biological and psychological traits. Trait theory focuses on the concept that criminals are born, not made for they can be predisposed to become a criminal behavior by theories such as the Biochemical Theory claiming that chemical imbalances in the body from an over and undersupply can lead to criminality for a minimum level of chemicals and minerals is needed for normal brain functioning and growth.…

    The biological positivism theory emerged in the late 19th century and marked a shift in the way that society looks at criminals. Prior to its conception, the criminal justice system was based on the classical theory which stated that, because everyone has free will, individuals who commit crime make a rational choice to do so (Bradley & Walters, 2011). Biological positivism was founded in an attempt to answer the question: “What makes a person choose to commit crime?”, something that classicism wasn’t interested in addressing. For this reason, biological positivism, in contrast to classicism, puts its focus on the criminal, not the crime. With the integration of the medical model into criminology that biological positivism brought, criminality…

    A number of theories put forward to explain the criminality of the poor boy’s actions who had stolen a bottle of juice from a shopkeeper and got caught. The theories can be generally classified into sociological theories and biological theories. Sociological theories will tend to explain the boy’s action of stealing the bottle of orange juice as a result of influence from his environment, while biological theory tries to explain the boy’s act of theft as being biologically oriented as such, and he has no control over them. Some of the sociological theories in this case include the strain theory, social control theory, the rational control theory, and the biological theory. 1.…

    In conclusion, the idea that man is “born criminal” has received a lot of support over the years, from various positivists and the evidence of case studies. With Cesare Lombroso being one of the founding fathers of the positivist movement, he brought with him controversial science in order to determine the criminal person, which then influenced many other biologists in this area. Since then, biological positivism has come a long way, with the use of forensics and fingerprinting still used today to identify criminals. The growing support from researchers like Dr James Fallon, has helped to show that this concept is still very current, as well as aiding positivism into the twenty first century. Nonetheless, biological positivism will continue…

    As ex-offenders are reintroduced into society, the aggression that was acquired within the correctional facilities affects them greatly in society. Researchers state that those who used aggression “struggled to control their anger and at the smallest provocation reacted with ferocity” (Chesla & Marlow, 2009). This behavior can lead individuals to return to correctional facilities at a higher rate because they lack the self-control when situations of conflict…

    Q.1. 1 [250 words] Name three major problems with the concept of crime as criminal behaviour. “Criminal behaviour is defined by the laws of particular jurisdictions, and there are sometimes vast differences between and even within countries regarding what types of behaviour are prohibited”. (Edge, 2016). One of the key problems is that throughout the world many countries consider some criminal acts to be more serious than others for example marijuana is an illegal drug in Ireland but is legal in Alaska.…

    For this week’s unit paper we are to summarize and provide an example of how biological, sociological, and psychological theories of crime causation affect human behavior and actions. Biological theories believe that somewhere there is a biological difference that make criminals commit crimes. There are two different theories that I feel could relate to this and those two would be neuroscience and genetics. Many people do not understand that the brain is very complex and fragile organ which can be damaged by traumatic injury, tumors, neurodevelopment disorders, neurodegenerative disorders, vascular lesions and many other causes. You may hear this in the court room a lot of times especially with juvenile’s.…

    Serial Killers Essay

    What this study does not take into consideration, is that among the general population abuse is underreported because many individuals who have suffered from abuse do not readily admit that they have been abused. In contrast abuse is likely over reported by people who commit heinous crimes in an effort to win sympathy from the jury. It is possible that if both the general population and the serial killer population were completely honest and the statistics were more accurate, than the difference between abuse frequency in the populations were not be as dramatic. There are many similarities besides just abuse in the childhood of most serial killers, “many were sons of prostitutes” and most had either absent or abusive fathers (Miller 138). Something unique to serial killers that is not found in normal people or even people who have committed murder that are not serial killers, is that “Unlike delusional psychotic murderers, serial murderers do know right from wrong” (Miller 138).…

    He claimed that things such as head size and shape, race or religion from which criminal came played big role. After deep researches and analyses Lombroso modified his theories and he identified two more series of different types of criminal such as insane criminals or habitual criminals. Insane criminals had some of the characteristics of a criminal however they were not born as criminals, they became criminal because of the brain alteration which then upset their moral nature. The second type of criminals had few anomalies but they rather fall into primitive tendencies for example because of poor…

    Contrasting traits between these two is that biological positivism rejects the concept of free will that is found in classical school of criminology. These leads into the explanation why positivism criminology is formed from hard determinism belief that crime results from external and internal forces that are beyond the control of the individual. Summation: All modern criminal justice systems assume the classical position that people are beings of free will, who deserve to be punished when they violate the law. Positivism did not disprove or destroy any principles set forth by the classical theory, it simply shifts the emphasis from one to another.…

    Summary Criminology studies the reasoning and factors as to why individuals engage in criminal activities. In classical criminology, social philosophers Cesare Beccaria and Jeremy Bentham developed a theory of crime that criminologist and theorist still use today (Akers 2017). In classical criminology, an individual commits a crime by making a rational decision. That decision is based off of whether the benefits that one might receive by offending outweighs the consequences such as being caught and cited or sentenced. Individuals base their decision to offend or not offend on what they have seen others suffer, their knowledge of what consequences they may endure and their own personal experiences.…

    In this essay I will reflect on the few assumptions and understandings I had about crime and see how they have changed. Upon arriving at De Montfort University to study Criminology and Criminal Justice, I had average knowledge about crime and punishment i.e. insight into biological and psychological perspectives of crime having studied A-level Law and Psychology beforehand. However I did expect to delve so deep into the history and other aspects of Criminology during this first semester. During A-level Law I have read many case studies of murder, manslaughter, GBH, rape etc. I found the main reasons behind committing these crimes were usually motives for revenge, loss of control, hate, rage, and biological inheritance of 'criminal genes ' such as Monoamine oxidase A which makes individuals more prone to exert violence.…
