“…to a large extent, differences in educational achievement can be explained by inherited differences in children’s DNA sequence”
“Choosing specific A-level subjects was found to have greater genetic influence (50% for humanities and 60% for STEM – science, technology, engineering and mathematics – subjects) and less influence from shared environment (18% for humanities, 23% for STEM). Genetic factors affected subject choice across a wide range of school subjects, including second language learning, mathematics and psychology.
The authors suggest that students make A-level choices in part on the basis of previous educational achievement, which is substantially heritable.”
…shared environmental effects are less than 25% for academic achievement and negligible for personality traits.
