DNA Predicts Intelligence and Success

Scientists can now predict over 10% of your intelligence just from your DNA. It’s not a single

“smart gene.” Instead, they use a polygenic score, which adds up the effects of thousands

of tiny genetic markers across your genome. This score is stable your whole life

and can predict your ability to learn from birth, long before any test could.

It’s already a better predictor of your future educational and career success than your family's

socioeconomic status. This isn't about genetic destiny, but it could completely change how we approach

education and understand why siblings can be so different.
