Genetic Basis for Crime: A New Look by Patricia Cohen

Introduction to the Genetic Basis for Crime

  • Context of Discussion: The article discusses the evolving perspective on the relationship between genetics and crime, highlighting historical resistance in criminology toward acknowledging genetic factors in criminal behavior. The discussion stems from a New York Times article by Patricia Cohen, published on June 19, 2011.

Historical Background

  • NIH Withdrawal of Funding: Less than 20 years prior, the National Institutes of Health (NIH) retracted funds for a conference centered on genetics and crime due to backlash regarding concerns over eugenics and racism.

  • Response from Experts: The president of the Association of Black Psychologists labeled the research a form of stereotyping.

  • Shift in Focus: This backlash led criminologists to predominantly ignore genetic explanations for criminal behavior, focusing instead on social causes, such as poverty, addiction, and gun violence.

Current Trends in Research

  • Return to Genetic Exploration: With the sequencing of the human genome, there has been a cautious resurgence among criminologists in examining genetic contributions to crime.

  • Panel Discussion Announcement: At the annual National Institute of Justice conference in Arlington, VA, criminologists discussed creating DNA databases and new genetic markers for forensic science.

  • Terrie E. Moffitt's Perspective: She noted that previously, criminologists avoided discussing genetics, but now modern theories integrate both social and biological factors in understanding crime.

Genetic Research Findings

  • Impact of Genetics on Criminal Behavior:

    • Researchers claim over 100 studies illustrate a genetic role in criminal behavior.

    • Detoxified Methodologies: With recent methodological advances, researchers emphasize that genetics interact significantly with environmental influences, shaping behavior.

Environmental Influences on Genetics

  • Gene-Environment Interaction:

    • It is emphasized that while genetics can predispose individuals towards aggression, environmental factors can either suppress or exacerbate these tendencies.

    • Many individuals with genetic predispositions may not act out violently due to a supportive environment.

  • Research Outcomes by Kevin Beaver:

    • Genetics were shown to explain little to no violent behavior in boys not exposed to risk factors.

    • In contrast, boys with multiple risk factors displayed 80% explained violent behavior linked to genetic predispositions.

Behavioral Traits Linked to Crime

  • Self-Control and Empathy:

    • Current research indicates self-control, callousness, and lack of empathy are significant behavior traits linked to criminal decision-making.

    • There exists debate regarding the genetic and environmental components' degree of influence on these traits.

Key Studies and Their Implications

  • Long-Term New Zealand Study:

    • A cohort of 1,000 babies born in New Zealand in 1972 were studied, revealing a strong correlation between low self-control at age 3 and likelihood of criminal conviction later in life.

    • Statistical findings: 43% of children in the lowest fifth of self-control faced later convictions, compared to 13% from the highest fifth.

    • A crucial takeaway is that predispositions are not determinative (i.e., knowing a trait is inherited does not presuppose an unchangeable fate).

Ethical and Social Considerations

  • Potential Misuse of Genetic Information:

    • Ethical dilemmas arise on whether genetic predispositions could influence sentencing or inform rehabilitation programs based on biological markers.

    • Discussions include identifying individuals with biological markers linked to violence, raising questions about labeling and stigma.

  • Troy Duster's Critique:

    • Advocates need to examine behaviors from all societal classes, not solely disadvantaged minorities, particularly critiquing a focus on white-collar crime.

Trends in Academia and Research Output

  • Resurgence of Interest:

    • John Paul Wright’s survey indicates increasing acceptance of genetics in criminology among younger scholars.

    • Publications on the genetic link to crime remain scarce in criminology journals over the past two decades, apart from a few exceptions.

Conclusion and Future Directions

  • Pragmatic Understanding:

    • Comprehensive understanding of the interplay between genetics and environment is crucial in crafting policies and societal interventions related to crime.

    • As genetic research continues to evolve, it remains important that sociological context accompanies biological inquiries into criminality to avoid misinterpretation and misuse of research findings.

  • Potential Research Avenues:

    • More in-depth studies are needed to clarify the roles various risk factors play in the expression of genetic predispositions toward aggression and criminal behavior.
