Well, Malachi, there are lots of people here who like to argue about the validity of the BullS**t Curve. I knew it would come up in this discussion sooner or later.
But for some reason, we never really see much addressing of prenatal care, education, etc, issues. A few people do bother to give lip service, and then proceed to claim that a few tests are completely unslanted socially, etc, and that they show that genetics is the primary determination... It gets tiresome, and the same people, when challenged, resort to simple, arrogant namecalling instead of addressing the issues.
(Which I suspect is because they can't, they don't show that race is what it's made out to be, they can't show that things like nutrition, prenatal care, etc, don't matter, and they don't want to take into account the economic implications. Given what has been demonstrated about early childhood development, making claims like "so you say it happens before year 2" and so on look like aggressive debating manouevers from someone who isn't interested in seeing the other side at all.)
Don't take me for one of them.
