Using DNA to predict educational trajectories in early adulthood

Area of Science:

• Behavioral Genetics
• Sociogenomics
• Developmental Psychology

Background:

• Educational and occupational decisions post-compulsory schooling shape adult life outcomes.
• Genetic influences on these critical life decisions have been largely overlooked.
• Understanding genetic contributions is crucial for a comprehensive view of developmental trajectories.

Purpose of the Study:

• To investigate the genetic underpinnings of early adult educational and occupational decisions.
• To examine the role of genomewide polygenic scores in predicting life course trajectories.
• To explore the concept of gene-environment correlation in decision-making.

Main Methods:

• Utilized genomewide polygenic scores (EA3) derived from a large-scale education GWAS.
• Analyzed a United Kingdom-representative sample of 5,839 individuals at age 18.
• Employed logistic regression to assess the predictive power of EA3 on post-compulsory trajectories.

Main Results:

• EA3 significantly predicted educational trajectories, explaining 10% of the variance.
• Increased EA3 scores were associated with reduced odds of pursuing full-time employment, apprenticeships, or NEET status.
• These genetic associations were partially attenuated by academic achievement and socioeconomic status.

Conclusions:

• Young adults' aspirations and decisions are partly shaped by their genetic predispositions.
• Gene-environment correlation plays a role in shaping educational and occupational pathways.
• DNA-based predictions offer new avenues for studying sociodevelopmental influences on life outcomes.
