saying things doesn't make them true, but studying them informs what you should think and say. https://pmc.ncbi.nlm.nih.gov/articles/PMC5985927/ https://pmc.ncbi.nlm.nih.gov/articles/PMC5985927/ Intelligence — the ability to learn, reason and solve problems — is at the forefront of behavioural 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. In this Review, we highlight the latest innovations and insights from the genetics of intelligence and their applications and implications for science and society. read what it says carefully: they've correlated genes to a small percentage of the heritability of intelligence. That means there is much more heritability than they have yet found a source for. Life is an intelligence test. During the school years, differences in intelligence are largely the reason why some children master the curriculum more readily than other children. Differences in school performance predominantly inform prospects for further education, which in turn lead to social and economic opportunities such as occupation and income. In the world of work, intelligence matters beyond educational attainment because it involves the ability to adapt to novel challenges and tasks that describe the different levels of complexity of occupations. Intelligence also spills over into many aspects of everyday life such as the selection of romantic partners and choices about health care1. This is why intelligence — often called general cognitive ability2 — predicts educational outcomes3, occupational outcomes4,5 and health outcomes6 better than any other trait. It is also the most stable psychological trait, with a Pearson correlation coefficient of 0.54 from age 11 years to age 90 years7. Box 1 describes what intelligence is and how it is assessed. see also https://en.wikipedia.org/wiki/Mainstream_Science_on_Intelligence#Statement https://en.wikipedia.org/wiki/Mainstream_Science_on_Intellig...
