Even if genes affect intelligence, we can’t engineer cleverness

16 Jan

First, let me tell you how smart I am. So smart. My fifth-grade teacher said I was gifted in mathematics and, looking back, I have to admit that she was right. I’ve properly grasped the character of metaphysics as trope nominalism, and I can tell you that time exists, but that it can’t be integrated into a fundamental equation. I’m also street-smart. Most of the things that other people say are only partially true. And I can tell.

A paper published in Nature Genetics in 2017 reported that, after analysing tens of thousands of genomes, scientists had tied 52 genes to human intelligence, though no single variant contributed more than a tiny fraction of a single percentage point to intelligence. As the senior author of the study Danielle Posthuma, a statistical geneticist at the Vrije Universiteit (VU) Amsterdam and VU University Medical Center Amsterdam, told The New York Times, ‘there’s a long way to go’ before scientists can actually predict intelligence using genetics. Even so, it is easy to imagine social impacts that are unsettling: students stapling their genome sequencing results to their college applications; potential employers mining genetic data for candidates; in-vitro fertilisation clinics promising IQ boosts using powerful new tools such as the genome-editing system CRISPR-Cas9.
