I'll try to unpack that, especially since the original post was so sloppy.
The original post said "But why is it that the rest of the world seems to think that individual genetic differences are okay, whereas racial genetic differences in intelligence are not?". This is incorrect. "The rest of the world" seems to think that individual genetic differences in intelligence exist and are meaningful, whereas racial genetic differences do not. (Does Yudkowsky really think that anti-racist activists believe that black people are inherently less intelligent and that that fact should be ignored? I'm not sure how else to read that.)
The unfairness of individual differences in intelligence is that, well, it happens and it's unfair. The unfairness of racial differences in intelligence is that they don't exist, but people act as though they do, and it's that second part that's unfair. These are two different kinds of unfairness. For the first, changing people's minds won't do a darned thing; it's like trying to persuade water to run uphill. For the second, changing people's minds will, following the above logic, reduce the amount of unfairness in the world, because the source of the unfairness is in those people's minds.
So, treating able-bodied people differently from disabled people is... well, it depends. If you treat someone in a wheelchair like they can't walk, that's the first kind. (They actually can't walk; it's not anyone's fault.) If you treat someone in a wheelchair with no obvious signs of mental impairment like they have impaired intelligence, that's the second kind. (They're just as clever as anyone else; the unfairness is entirely in the way you're treating them.)
Does that clear things up a bit?
Yes, thanks for clarifying.
I agree with you that there's a difference between treating groups differently based on differences that actually exist, and based on differences that don't actually exist, and that the second thing involves a kind of unfairness that's different from the first thing.
That said, it does seem to me that a lot of people not only think that racial genetic differences in intelligence don't exist, they also think that if racial genetic differences in intelligence did exist, that would be a bad thing, in a way that they don't think that the existence of individual genetic differences in intelligence are a bad thing.
Do you disagree?
Idang Alibi of Abuja, Nigeria writes on the James Watson affair:
An intriguing opening. Is Idang Alibi about to take a position on the real heart of the uproar?
Darn, it's just a lecture on personal and national responsibility. Of course, for African nationals, taking responsibility for their country's problems is the most productive attitude regardless. But it doesn't engage with the controversies that got Watson fired.
Later in the article came this:
This intrigued me for two reasons: First, I'm always on the lookout for yet another case of theology making a falsifiable experimental prediction. And second, the prediction follows obviously if God is just, but what does skin colour have to do with it at all?
A great deal has already been said about the Watson affair, and I suspect that in most respects I have little to contribute that has not been said before.
But why is it that the rest of the world seems to think that individual genetic differences are okay, whereas racial genetic differences in intelligence are not? Am I the only one who's every bit as horrified by the proposition that there's any way whatsoever to be screwed before you even start, whether it's genes or lead-based paint or Down's Syndrome? What difference does skin colour make? At all?
This is only half a rhetorical question. Race adds extra controversy to anything; in that sense, it's obvious what difference skin colour makes politically. However, just because this attitude is common, should not cause us to overlook its insanity. Some kind of different psychological processing is taking place around individually-unfair intelligence distributions, and group-unfair intelligence distributions.
So, in defiance of this psychological difference, and in defiance of politics, let me point out that a group injustice has no existence apart from injustice to individuals. It's individuals who have brains to experience suffering. It's individuals who deserve, and often don't get, a fair chance at life. If God has not given intelligence in equal measure to all his children, God stands convicted of a crime against humanity, period. Skin colour has nothing to do with it, nothing at all.
And I don't think there's any serious scholar of intelligence who disputes that God has been definitively shown to be most terribly unfair. Never mind the airtight case that intelligence has a hereditary genetic component among individuals; if you think that being born with Down's Syndrome doesn't impact life outcomes, then you are on crack. What about lead-based paint? Does it not count, because parents theoretically could have prevented it but didn't? In the beginning no one knew that it was damaging. How is it just for such a tiny mistake to have such huge, irrevocable consequences? And regardless, would not a just God damn us for only our own choices? Kids don't choose to live in apartments with lead-based paint.
So much for God being "just", unless you count the people whom God has just screwed over. Maybe that's part of the fuel in the burning controversy - that people do realize, on some level, the implications for religion. They can rationalize away the implications of a child born with no legs, but not a child born with no possibility of ever understanding calculus. But then this doesn't help explain the original observation, which is that people, for some odd reason, think that adding race makes it worse somehow.
And why is my own perspective, apparently, unusual? Perhaps because I also think that intelligence deficits will be fixable given sufficiently advanced technology, biotech or nanotech. When truly huge horrors are believed unfixable, the mind's eye tends to just skip over the hideous unfairness - for much the same reason you don't deliberately rest your hand on a hot stoveburner; it hurts.
