Why genes don't count (for racial differences in health).

Area of Science:

• Genetics
• Sociology
• Anthropology

Background:

• Genetic data historically supported the concept of race.
• Since the 1970s, genetic data have disproven the concept of biological races.
• Human genetic variation is continuous, not discrete, and predominantly exists within populations.

Purpose of the Study:

• To examine the paradoxical relationship between "race" and genetics.
• To critique the use of genetic variation to explain racial differences in disease.
• To highlight the limitations of using race as a proxy for genetic variation.

Main Methods:

• Analysis of historical and contemporary genetic research on race.
• Critique of the assumptions underlying genetic explanations for racial disparities.
• Exploration of the interplay between genetics, social factors, and health.

Main Results:

• Genetic variation does not align with socially defined racial categories.
• The notion that genetic variation explains disease variation is a form of geneticization.
• Attributing disease variation to race is a form of racialization, exaggerating race's biological significance.

Conclusions:

• Race is not a valid biological construct, and genetic variation does not support it.
• Using race as a proxy for genetic differences obscures the impact of political-economic factors and lived experiences on health.
• Understanding the complex processes of racialization and racism is crucial for addressing health disparities.
