Anyway, David Reich argued in the NYT that there are genetic differences between populatons which do influence behaviour and mental traits. It is only a question if we want to find these (or leave the field to racists):
> since all traits influenced by genetics are expected to differ across populations (because the frequencies of genetic variations are rarely exactly the same across populations), the genetic influences on behavior and cognition will differ across populations, too.
The point of knowing this is so you can treat it. You can raise the IQ of a phenylketonuric by not feeding them Diet Coke. It doesn’t seem like the HBD people would be happy seeing this, because they just want to prove someone is inherently superior and someone else isn’t.
To put it another way, if a scientist does a study and shows that the Ainu people of northern Japan are statistically taller than the Mbuti people of the Congo, does that mean the scientist is a "scientific heightist"? Wouldn't they need to amend their report with something like "...and therefore, Ainu people are better than Mbuti" or something like that?
