Biosocial Criminology
Definition
An approach that treats biological and social factors as mutually constitutive rather than alternative explanations for crime. It holds that genetic or neurological risks do not cause crime independently; they increase vulnerability to environmental triggers and reduce resilience to adverse social conditions.
- Core claim
- Biology and environment interact, neither acts alone
- Rejects
- Pure biological determinism of crime
- Mechanism
- Genetic/neurological risk raises vulnerability to triggers
- Field
- Criminology, theories of crime
Common questions
How does biosocial criminology differ from older biological theories of crime?+
Earlier biological theories treated traits like brain structure or genetics as directly causing criminal behaviour on their own. Biosocial criminology instead treats these traits as risk factors that only translate into behaviour depending on environmental conditions such as abuse, poverty, or peer influence.
What kind of evidence supports a biosocial rather than a purely social explanation?+
Twin and adoption studies showing that genetic risk predicts antisocial outcomes more strongly in adverse environments than in supportive ones are commonly cited, since they demonstrate a gene-by-environment interaction rather than either factor acting in isolation.
