Genetic Prediction and Societal Implications
Genetic prediction, through tools like polygenic scores, can significantly forecast various life outcomes, including income and educational attainment. Research indicates that genetic variations account for a notable portion of income variation—58% in men and 46% in women. This challenges common perceptions that intelligence and socioeconomic status are solely determined by environmental factors. Such findings suggest a complex intertwining of genetics and social conditions, raising concerns about potential entrenched inequalities rooted in genetic differences.
