Belsky: 

No. We’re still a long way from being able to accurately estimate human potential with a genetic test—and even if we could, there are lots of reasons that it wouldn’t be a good idea. To develop our predictive model, we started with the results of large data-mining studies involving tens of thousands of human genomes, which identified gene variants linked with particular educational outcomes and the strength of those links. We used that information to create an algorithm that calculates something called a “polygenic score” for individuals, which indicates how many of the variants they have. When we looked at the Dunedin study data, we did find that participants with higher polygenic scores were slightly more successful than those with lower scores, but the effect was very small—just 1% to 4% of the variance.

Also, we’re talking about average outcomes. Some people with low polygenic scores went>
