We are living in extremely interesting times. We may have reached a tipping point in genomic research. It seems that we can now weakly predict life outcomes based on genetic tests. Daniel Belsky from Duke University and his team of researchers have recently released a paper asserting that genetic tests can predict adult life outcomes. The magnitude of correlation between genomic tests and adult life outcomes is still very modest, but I believe that the predictions will grow more accurate once we gain more knowledge about the genetic makeup of ‘success’. I believe that this is big news, since this is the first well-developed psychometric/genetic research I have read so far that asserts that life success is to some extent related to our genetic makeup.
When Belsky et al looked at the genetic profiles and the people they studied, they found that people with higher polygenic scores did not only have greater educational attainments, but also had more prestigious occupations, higher incomes, more assets, greater upward social mobility, and were more likable and friendly.
