“The New Genetics of Intelligence”, 2018 (; backlinks; similar):
Intelligence—the ability to learn, reason and solve problems—is at the forefront of behavioral genetic research.
Intelligence is highly heritable and predicts important educational, occupational and health outcomes better than any other trait.
Recent genome-wide association studies have successfully identified inherited genome sequence differences that account for 20% of the 50% heritability of intelligence.
These findings open new avenues for research into the causes and consequences of intelligence using genome-wide polygenic scores that aggregate the effects of thousands of genetic variants.
