Race and IQ

I recently got dinner at a hole-in-the-wall asian spot with a geneticist named Razib Khan. Over noodles, and with a concerned glance over his shoulder, he admitted that the science is clear: race is absolutely tied to IQ. Jews are the smartest. Pretty much everyone on the continent of Africa is at the bottom.

This fact alone is controversial, but we have to be able to talk about it, and here’s why:

I nodded, and asked: How many generations does this take to change?

Razib: As little as three generations. For example, the Egyptians used to be the smartest, but a century of inbreeding knocked them to the bottom. Incest drops IQ by 10 points in the first generation. After that the effect weakens.

This is huge. At first glance, the controversial statement seems like a slamdunk for racists the world over. But dig into the details, and you find out 3 generations is enough to change things—this means that race and IQ are not inherently linked as far as we know, they’re just linked in today’s world, because of today’s policies and systems.

Knowing this could actually help us target where we need to focus our interventions for the next three decades. Let’s get us all up!
