Genes Don't Just Predict Intelligence, But Also How Well You Do In School

sciencehabit writes: If you sailed through school with high grades and perfect test scores, you probably did it with traits beyond sheer smarts. A new study of more than 6000 pairs of twins finds that academic achievement is influenced by genes affecting motivation, personality, confidence, and dozens of other traits, in addition to those that shape intelligence (abstract). The results may lead to new ways to improve childhood education.

It didn't need to, the study was on twins. Further, testing on both identical and fraternal twins allowed researchers to calculate how much genetics plays into it, because the genetic makeup for both kinds of twins is highly predictable.
