Evaluating biological theories of criminality. Flashcards
Evaluating Lombroso’s theory, what are the strengths?
- He had created empathy for offenders
- basis of modern day profiling
- scientific study of observable features - in a controlled lab environment
Evaluating Lombroso’s theory, what are the limitations?
- scientific racism - most of the atavistic features described people of African descent, work was popular with eugenicists.
- biological determinism - ignores external factors
- prejudice and stereotyping
- no control group of non-criminals - contrasting research by Goring who compared prisoners and non-offenders found no evidence of physiological differences - lacks scientific credibility
evaluating genetic theories, what are the strengths?
used adoption studies - nature and nurture are separate - makes them more valid than twin studies
evaluating genetic theories, what are the limitations?
- heavily relies on twin studies: environment similarities rather than genetic. Nature vs. nurture?
- genetic theories assume there is a simple cause of offending: ignores the complexity of other factors such as psychological, biological, and social factors that cause criminality.
- adoption studies- they tend to have small sample sizes so it lacks generalisability and the findings are harder to obtain.
evaluating neural theories, what are the strengths?
Brower and price found a link between frontal lobe dysfunction and violent crime - strongly suggests that there is a neurological link between brain abnormality and criminality
evaluating neural theories, what are the limitations?
- biological reductionism: overlooks the role of nurture and all other factors that may contribute to why someone offends
-ethical questions: difficult to determine if it can be used as a defense case - there are other factors that lead to criminality - all the research is carried out after the offence: can not establish cause and affect, whether it was a traumatic head injury or an illness later on
evaluating biochemical theories, what are the strengths?
-can be used as a basis for crime prevention and treatment for offenders: practical application, developed drug treatments to balance serotonin and dopamine
-scientific methods and procedures: produces more valid data, we have a clearer understanding of the process that underpin criminality
- explains gender differences in offending: provides greater insight to rates of offending eg. understanding the role of testosterone in offending.
evaluating biochemical theories, what are the limitations?
biological reductionism: oversimplifies the cause of offending to a simple chemical explanation, the behaviour could arise from a much more complex interaction of factors.
