Introduction to Biological Perspectives in Criminology

• Biological Theories of Crime: - Crime is viewed as the result of:

  • Individual traits in biology (genes, neurology, chemical balance)

  • Behaviors altered by substance ingestion.

• Key Theorists: - Cesare Lombroso:

  • Proposed "stigmata" (physical indicators) were indicative of a born criminal.

  • William Sheldon:

  • Introduced the idea of somatotypes (body shapes) correlating with criminal behavior.

The Lead-Crime Hypothesis

• Lead exposure reduces cognitive abilities and increases aggression.

• Marginalized groups, like Aboriginal and Torres Strait Islander populations, are more affected.

• Environmental cleanups lower lead levels and crime rates.

  Lead Exposure in Australia:

  - Lead has been eliminated from petrol and paint, but still exists in dangerous quantities in some communities, especially from household fixtures (e.g., pipes).

  • Specific cities (Mount Isa, Port Pirie, Broken Hill) have mining and smelting operations with documented high lead levels in children exceeding actionable limits.

  • Disparities:

  • Aboriginal and Torres Strait Islander children are more frequently impacted by lead poisoning.

  • Higher lead levels correlate to increased crime rates and violent incidents.

• Reference Articles: - Daley et al. (2018) on lead toxicity.

  • Howarth (2012) on implications for general practice.
