Biological and biosocial criminology
The predestined actor
Classical presentations of the ‘rational actor’ first emerged in the 1700s
Dominant until the mid 1800s
Association between opportunity and crime
Deterrence should be the focus of the CJS
During the 1800s scientific advancement and the process of bureaucratic civilisation revealed problems
Cime stats were published in france in 1827
Distribution of offences was not equal
Deterrence was minimal
Criminology’s ficus turned towards determinism and positivism
Positivism:
Application of the methodology of the naturla sciences
Knowledge is derived from observation nit speculation
Theory not philosophy
Determinism:
Biological, psychological and sociological
Opportunity and choice are not casual
Environmental conditions provoke or restrain they do not cause crime
Choice is mediated by ‘predestined’ characteristics
Offenders are distinct from non-offenders
Marks a shift from a philosophy to a social science
Theories rather then ideas
Empiricism
A focus on the actor rather than the act
Determinism
Differentiation
Pathology
Key points
Positivists argue that criminology should focus on the scientific study of offenders and offender behaviour
Dominant form of criminology from the mid 19th century
Positivism is not a theory it is an epistemology
Offenders and non-offenders are different
This difference lies in factors beyond individual control
The foundations of Biological Positivism
Influenced by advancements in the natural sciewnces
Origin of species
Pathological offender
Emphasis placed explaining behaviour via biology and physiology
The most influential movement was the ‘Italian school’
Cesare Lombroso (1825-1909)
Enrico Ferri (1856-1929)
Raffaele Garofaio (1851-1934)
Physical typology Theories
Based on the hypothesis that offenders represent distinct substrata of the species
Manifest in degeneracy
First ‘scientific’ thesis expressed via Phrenology ad Physiognomy
Cesare Lombroso
The Criminal Man (1976)
The Female Offender (1895)
Offenders are physically different from law-abiding citizens
Atavism — evolutionary throwbacks
The Born Offender
The Underclass
First attempts to categorise offenders by their individual and demographic characteristics
Atavistic offenders
Epileptic
Imbecilic
Born
Occasional offenders
Criminaloids
Habitual criminals
FIrst systemativ testing by Charles Goring (1931)
Prison inmates with university undergraduates, soldiers, professors and hospital patients
No statistically significant differences between behaviour and 37 physical traits
Controlling for social class and age prisoners were shorter and thinner than members of the general population
Less intelligent
Rejected Lombroso’s conclusions whilst still maintaining that offenders represented distinct moral, physiological and mental types
Sheldons somatotypes (1949)
Endomorphs
Mesomorphs
Ectomorphs
Glueck and Glueck (1950)
The association between body type and personality type
Criminal Heredity Theories
Again beased around Darwinian processes
Goring (1913)
Goddard (1912)
Dugdale (1895)
‘Social’ Darwinism
Correlations between the criminality of children and parents
Feeblemindedness
Moral degeneracy
Evaluating the foundations of biological positivism
Absolute determinism is deeply problematic
Lacks spuriousness
Remember the ‘tests’ for good theory
Many theories could not be falsified during the period
Widespread methodological inconsistency
Limited empirical testing
Policy implications impractical and morally incompatible with democratic criminal justice models
Key points
19th century marked the birth of modern criminology
Shift towards a scientific approach (positivism)
Shift towards a ‘predestined’ approach (Determinism)
The ‘Italian school’ was the first major movement within criminology
Argued that crime was the product of defective biology
Defects are linked to evolutionary principles
Evidenced via physical or mental abnormality
Early theories are now entirely discredited
Atavism and feeblemindedness are dead concepts
Body type and hereditary explanations remained influential into the 20th century
Emergence of other forms of determinism and the connection between the science of Eugenics and the Holocaust end the dominance of biological determinism
Biosocial criminology
Biological sciences have made more progress in understanding crime over the last 10 years than social sciences have made in the last 50…Lombroso’s legacy is the miseducation of criminologists (Robinson, 2004 quoted in Wright et al., 2008 p. 325)
Genetic influence (normal and abnormal)
Biochemical explanations
Neuropsychological
Each area contains an array of individual theoretical models
Biosocial criminology offers the widest theoretical
Adaptation of the predestined and determined actor
Nature and nurture not nature vs nurture
Risk factor paradigm
Genetic inlfuecnes
Exploring genetic influences does not necessitate a fundamentally deterministic approach
As crime is a social defined concept no modern theory attempts to link offending with genetic propensity
Genes may influence co-morbid factors associated with crime eg. alcoholism, mental illness
Genes may influence criminal risk factors eg. aggression, low self-control
Whilst genetic potential is fixed expression of this potential is influenced by the environment
“What is inherited is not a tendency to commit criminal acts as such, but rather a predisposition to develop certain aspects of personality, some of which may be linked to criminal behaviour” (Ainsworth, 2000 p. 72)
Various expressions of this thesis but all except that biological predisposition combined with shared and non-shared environments increases criminal propensity
Madnik (1977-2002) Biosocial theory is the most systematically tested of such models
Proposes that some genetic factors linked to offending are passed via genetic inheritance
Such factors do nor directly ‘cause’ offending but rather increase susceptibility to criminogenic environments
Based on low arousal within the autonomic nervous system
Comparison between concordance rates of monozygotic and dizygotic same-sex twins
Tests the concordance of behaviour
If no influence identical twins would be ni more concordant than fraternal twins
If identical twin behaviour is more concordant a possible genetic link is established
Concordance is offending is evident across empirical work
Meta-analysis suggests concordance is significant (cf. Raine, 1993)
Issues separating biological and sociological influences
Small number of studies have separated twin samples
Childhood conduct disorder (CD) and adult antisocial personality disorder (ASPD) heritability 41% for CD and 28% for ASPD
Likewise studies looking at attention deficit hyperactivity disorder (ADHD) have yielded similar results
Adoption studies provide another opportunity to test Mednick’s hypothesis
Children separated at birth from biological parents (BP) and reared by adoptive parents (AP)
Shared genetics with BP and shared environment with AP
Generally children’s offending more similar to BP
Again difficult to separate biological from environmental variable
Genetic mutation
Variation on genetic theory which focuses on pathological genetic development
Mutation in genes andor gene activators
Mutation of sex chromosome pairing
Abnormal complement
Female: XXX
Male: XXY; XYY; XXYY; XYYY
Biochemical influences
Has explored both pathological and normal functioning of biochemical processes
Wide area so study:
Low arousal within the ANS
Hormones
Neurotransmitters
ANS
The autonomic nervous system (ANS) is the regulatory sector of the CNS
Responsible for controlling arousal
ANS responsiveness plays a role in the social learning of law-abiding behaviour
Low ANS rates may inhibit conditioning
Hormones
Hormones — Biochemical messengers in the body secreted into the bloodstream by endocrine organs through the body
Research has tended to focus on testosterone
Aggression keyed to violent and sexual offending
Impulsiveness keyed to substance use, non violent offending and antisocial behaviour
Neurotransmitters
Neurotransmitters — Chemicals that enable electrical transmission between neurones
Serotonin, norepinephrine and dopamine have been related to offending
Significant relationship between high or low levels and offending
Focuses on the ability to inhibit aggression
Interestingly such work is increasing being applied to normal biological variation:
Activation of the hypothalamic-pituitart-gonadal axis
Increase in testosterone
Neurochemical change
Increase in excitatory neurotransmitters — dopamine
Decrease in inhibitory neurotransmitters — serotonin
- Biosocial criminology offers the widest theoretical coverage in
criminological theorisation
- Modern biosocial Criminology is an adaption of the ‘predestined’ and
determined’ actor
- Nature & Nurture
- ‘Soft’ Determinism
- No longer simply the pathological offender
- Looks at both normal and abnormal biology
- A new frontier for Criminology
New frontiers in biosocial criminology
Nuropsychology
Executive functions located in the frontal lobes
deficits on executive functions related to poor decision making and low self control
Research focused on the prenatal or postnatal trauma (Moffitt, 1993)
Raine (1993) correlation between trauma in week 1 and age of arrest
Only cases of environmental risk comorbidity
Structural and functional differences between ‘male’ and ‘female’ brains
Female brains have a larger and more active prefrontal cortex
Variation in risk and fear responses keyed to the amygdala (Hall et al., 2000)
Age related structural change
Risk taking as a neurobiological developmental stage (Steinberg, 2007)
Significant restructuring of the prefrontal cortex
Evolutionary Criminolgy
Seeking to explain behaviour with reference to human evolutionary history
Darwinian principals of natural selection and Genetics
Criminalised behaviour is an adaption to a hostile environment
Evolutionary mechanisms:
Parenting effort
Mating effort
Criminalised behavior includes adaption to a hostile environment (cf. Ellis & Walsh, 1997)
“To say that human behavior cannot be analyzed in evolutionary terms require the acceptance of a genuinely bizarre proposition, namely, that we alone amongst animal species have somehow managed to achieve independence from our evolutionary history” (Alcock, 2001 p. 223)
Disposition to commit sexual offences (Ellis and Walsh, 1997, 2008)
Nutrition
Longstanding recognition of links between
diet and general healthNew focus on behaviour and cognitive development
Diet and nutrition's role in antisocial conduct
Most research directed towards delinquency
Food allergies and additives
Vitamin and mineral deficiencies
Cumulative toxicity
The effect of nutrition on cognitive development has been studied for decades (cf. Brown & Pollitt, 1996)
link among cognitive deficits, brain functioning, and crime
Recent work has shown that nutrition can help prevent antisocial behaviour (Cf. Farrington & Welsh, 2007; Olds et al., 2007)
