MedicalResearch.com: What is the background for this study?
Dr. Benjamin: Educational attainment is primarily determined by environmental factors, but decades of twin and family studies have found that genetic factors also play a role, accounting for at least 20% of variation in educational attainment across individuals. This finding implies that there are genetic variants associated statistically with more educational attainment (people who carry these variants will tend on average to complete more formal education) and genetic variants associated statistically with less educational attainment (people who carry these variants will tend on average to complete less formal education). But none of these genetic variants had been identified until our 2013 paper on educational attainment. That paper, which studied a sample of roughly 100,000 individuals, identified 3 genetic variants associated with educational attainment, each of which has a very small effect. In the current paper, we expanded our sample to roughly 300,000 individuals, with the goal of learning much more about the genetic factors correlated with educational attainment.
