" There is data [on race and intelligence]. My claim is that it doesn't mean what we think it means. There isn't enough work; there aren't enough people who have done the work – and the definition...I mean, trust me: "heritable" is a serious problem.

Because...for example, let's say that there was a belief that people who had a brow ridge, or something, were stupid. And that belief was widespread. And that brow ridge was genetically encoded, and it resulted in people going into the world and facing discrimination in school, let's say, because the brow ridge connoted to the teachers that they were not likely to be intelligent, and therefore they were given simpler lessons; they got dumbtracked or something like that.

That would show up as a genetically heritable difference in intelligence between brow-ridged people and non-brow-ridged people. That does not mean that it was encoded in the genome and that it was the brain that was blueprinted...what it means is that some feature that was encoded in the genome caused the environment to interact with the individual in a way that then produced a difference in intellect.

[...] It is so early in the study of this stuff, we really don't know. And the taboo nature of those questions is causing a vacuum that is being filled with an artificially pure (and probably not correct) perspective. "
