It is this culture, he reveals, that really nurtures the serial killer in society and allows him to grow into the killer that he becomes. Jarvis tracks the sale of murderabilia and the depiction of serial killings in popular films and television (Saw, American Psycho, CSI, Law & Order, Nightmare on Elm Street) to show how a culture of death permeates modern culture. But with the murderabilia culture, this cycle of ownership is perpetuated and nurtures the sentiment that drives serial killing. This was certainly the case for Dahmer, who wanted to possess his victims sand essentially own them, which is why he killed them. This study suggests that serial killers and the culture that drives them is nurtured by a need to commoditize murder and make it into something tangible that people can posses. Monsters Inc.: Serial killers and consumer culture. The best way to answer the question, according to this study, is to acknowledge that both nature and nurture play a role in the development of the serial killer and that each aspect has to be examine more fully on an individual basis, as no two serial killers or criminal minds are exactly the same - each comes from its own background and has its own genetic/psychosocial make-up that contributes to the killer's evolution. It shows that there is no easy answer to the question and that both angles need to be considered deeply in order to produce a coherent and cohesive picture of why serial killers act. nurture and the serial killer/criminal mind. The study is significant because it addresses head-on the question of nature vs.
#WHAT MAKES A SERIAL KILLER NATURE VS NURTURE SERIES#
It is not merely the effect of a genetic disorder that motivates the killer but rather a series of compounding factors that gradually pushes the killer towards that direction. That, however, is not the complete story, as the researchers also indicate that nurture also plays a part in the development of a serial killer like Ted Bundy. The researchers also use the example of Ted Bundy as a serial killer who came from a normal, healthy, loving family but who had low levels of MAOA and thus had a higher risk of deviating towards aggressive behavior. They identify articles that support the notion that nature is a significant factor in the make-up of the criminal mind, as numerous researchers have revealed that "low levels of monoamine oxidase a gene (MAOA) lead to higher rates of aggression" (p. nurture question in regard to what makes up the mind of a criminal. UC Merced Undergraduate Research Journal, 8(1): 1-10. Highsmith, J., Mercado, M., Hernandez, J., Madrigal, S. For this reason, the study makes a supportable claim for the nature side of the debate over whether it is nature or nurture that leads serial killers to act. The study calls for more investigation into this correlation and is significant because it draws attention to head trauma and/or biological dysfunction as a role player or facilitator in the serial killer's natural motivation. Thus, the conclusion of the researchers is that there is a correlation between a negatively impacted nature and the development of serial killers. Roughly 20% of the same sample had suffered a head injury.
For example, the study notes that out of 239 serial killers analyzed for the study, 28% "had definite, highly probable or possible" autism spectrum disorder. However, it is important to note that correlation does not equate to causation and the study merely depicts a correlation between autism spectrum disorder and serial killing: it does not assert that the former is the cause of the latter, just that it is a common theme. This finding indicates that nature plays a distinct role in the motivation of serial killers. What the study finds is that a "significant proportion of mass or serial killers have had neurodevelopmental disorders such as autism spectrum disorder or head injury" (p. The researchers in this study conduct a meta-analysis of relevant literature including academic studies and legal sources in order to assess the "complex interaction of biological, psychological, and sociological factors" that contribute to the making of a serial killer (p. Aggression and Violent Behavior, 19(3): 288-301. Neurodevelopmental and psychosocial risk factors in serial killers and mass murderers. Allely, C., Minnis, H., Thompson, L., Wilson, P., Gillberg, C.
