"Yet the Problem Remains": Why Genetic Determinism Still Haunts Biomedical Research

Area of Science:

• Population genetics
• Human genetics
• Bioethics

Background:

• Post-Holocaust, population geneticists aimed to differentiate their work from Nazi eugenics.
• Despite advancements, modern genetics struggles to avoid associations with weaponized genetic data and determinism.
• Historical eugenics movements exploited genetic theories for harmful social policies.

Purpose of the Study:

• To identify and analyze current practices in population genetics that perpetuate genetic determinism.
• To examine how seemingly well-intentioned research may inadvertently echo historical eugenicist approaches.
• To propose actionable recommendations for improving ethical standards and practices in the field.

Main Methods:

• Analysis of common practices in population genetics research and communication.
• Identification of ambiguous language and flawed data interpretation in genetic studies.
• Evaluation of environmental and societal factors often overlooked in genetic analyses.
• Review of the implications of mathematical population segregation in genetic research.

Main Results:

• Practices such as vaguely stating "genes matter," using ambiguous examples, and relying on flawed data contribute to genetic determinism.
• Environmental factors are often homogenized, ignoring deleterious exposures, and populations are segregated mathematically.
• A lack of accountability for predictable harms arises from claiming no intent to harm, hindering necessary changes in standard practices.

Conclusions:

• Modern population genetics risks echoing historical eugenics through specific, identifiable practices.
• Continuous mechanistic evaluation is crucial to address the persistent associations between contemporary genetics and past eugenics.
• Implementing discrete recommendations is necessary to foster a more equitable and ethically sound future for population genetics.
