Studies link genes to IQ with little predictive accuracy

By 2018, gene studies involving more than 200,000 test takers had found correlations between 500 human genes and academic success. Based on these results, the behavioural geneticist Robert Plomin claimed that parents would be able to use consumer tests to enable "precision education", built around accurate predictions of their children's mental abilities. Even though DNA variations linked to test scores explained less than 10% of the difference in intelligence among the Europe-descended individuals who had been studied, new services such as GenePlaza and DNA Land were offering to estimate an individual's genetic IQ from a saliva sample.
