Outline of Biological Theories

  • Origins and assumptions of biological theories
  • Early biological theories
  • Connection between biological theories and eugenics
  • Introduction to biosocial criminology
  • Strengths, weaknesses, and implications of these theories.

Paradigm Shift in Criminology

  • Classical school of thought lost favour due to inability to explain or prevent crime.
  • Darwin’s Theory of Evolution shifted focus towards biological determinants of behavior rather than free will.
  • Transition from Classicalism to Positivism:
    • Positivism emphasizes that criminal behavior has causes beyond personal control.
    • Focus on scientific methods and the concept of predispositions in modern theories.

Origins & Assumptions of Biological Theories

  • Patterns indicate crime is concentrated in specific individuals/groups.
  • Biological positivists aimed to identify and control these 'born criminals'.
  • This contrasts with the classical view that emphasizes personal accountability.

Biological Positivism and Eugenics

  • Eugenics aims to improve genetic quality via selective breeding, linking criminal behavior to genetics.
    • Early biological positivists viewed eugenics as a preventative measure against crime.
    • Led to unethical practices (e.g., forced sterilizations).

Early Biological Theories

Craniometry
  • Belief that brain/skull size indicates superiority/inferiority.
  • Biased findings as researchers knew the identities of subjects prior.
Phrenology
  • Suggests skull contours relate to personality traits.
  • Refuted by modern understanding of brain function.

Lombroso’s Theory of Atavism

  • Cesare Lombroso’s theory: criminal behavior is atavistic, represented by primitive ancestors.
  • Individual classifications include:
    1. Born criminals
    2. Criminal by passion
    3. Insane criminals
    4. Occasional criminals (criminaloid, epileptoid, habitual).
  • Lombroso’s criteria (stigmata) for atavism included various physical characteristics.

Sheldon’s Somatotyping Theory

  • Linked physical body types to personality traits:
    • Endomorphic: jolly/lazy (obese)
    • Mesomorphic: aggressive/risk-taking (muscular)
    • Ectomorphic: introverted/shy (thin).

Development of IQ Testing

  • Binet’s IQ measure aimed to identify children needing educational support.
  • Misuse of IQ in eugenics to filter out 'undesirable' individuals.

Historical Impact of Eugenics on Crime Policies

  • The eugenics movement targeted perceived 'feeble-mindedness' to combat social issues like crime.
  • Sexual Sterilization Act in Canada allowed sterilization of vulnerable populations.

Biosocial Theories

  • Recognition of genetic factors alongside social influences in criminal behavior.
  • Interaction of nature and nurture essential for understanding crime.
  • Twin studies provide insight into genetic vs. environmental influences on behavior.

Strengths of Biosocial Theories

  • Holistic understanding of human behavior.
  • Early intervention potential in the criminal justice system.
  • Personalized rehabilitation approaches.

Weaknesses of Biosocial Theories

  • Risk of determinism; overlooks individual agency.
  • Ethical concerns about stigmatizing individuals based on genetics.
  • Limited predictive ability in determining who will commit crimes.

Implications of Biosocial Theories

  • Development of early intervention programs for at-risk individuals.
  • Biological treatments for related psychiatric disorders.
  • Possible reforms in legal frameworks considering biological predispositions.

Questions for Review

  • Prepare to discuss the complexities and nuances of biological theories in criminology, their historical implications, and current relevance in societal contexts.
