Socio-economic status is a social construct with heritable components and genetic consequences

Area of Science:

• Sociogenomics
• Behavioral Genetics
• Social Epidemiology

Background:

• Socio-economic status (SES) clusters within families and geographically, showing a strong association with genetic effects.
• Historical scientific research has explored the intricate relationship between SES and heredity.
• Recent genomics research provides new insights into this complex interplay.

Purpose of the Study:

• To review the history of scientific research on the relationship between SES and heredity.
• To discuss recent genomics findings concerning the hypothesis that SES is a dynamic social construct.
• To explore how genetically influenced traits contribute to achieving or maintaining SES and affect gene distribution.

Main Methods:

• Literature review of historical scientific research on SES and heredity.
• Analysis of recent genomics research findings.
• Discussion of sociogenomic hypotheses and evolutionary selection pressures.

Main Results:

• SES is robustly associated with genetic effects, clustering in families and geography.
• Genetically influenced traits may play a role in achieving or retaining socio-economic positions.
• Social stratification leads to differential environmental exposures and potential evolutionary selection pressures.

Conclusions:

• Genomics research uncovers hidden genetic consequences of societal organization.
• Understanding the interplay between SES, genetics, and social structures is crucial.
• Insights should be approached cautiously to foster a fair and functional society.
