To do this, researchers are turning to a relatively new genetic approach called the polygenic score, which assesses a person’s likelihood for a specific future based on a combination of genetic variables. It’s a research technique that some scientists are using to assess obesity or cancer risk, for instance. Now, researchers are exploring this approach in non-medical contexts, like academic or athletic success.
However, scientists are urging caution with the use of this new study. The accuracy of this new genetic approach is not yet proven.
