I would say that most things are in no way incompatible with racism or white supremacism -- but that finding (and publicising) an Asian IQ advantage is incompatible (at least, for a white racist). But then my concept of racism might be different: I mean it to be any attempt to position members of some/all other races as inferior in some morally important respect, in order to justify treating them badly.
Do you know if Rushton's beliefs that Asians are inferior in other areas are based on experiments? I'd be interested in any links you might have.
I have a few objections, but for now I'll focus on what I take to be the underlying issue that we disagree on.
> It doesn't change the basic purpose of the endeavor, which is to purport to rank the peoples of the world by intellectual capacity.
Based on this statement, I suspect our fundamental disagreement is over whether it does more harm than good to consciously deny empirical evidence for something when it has the potential to be spun into harmful propaganda. My position is that, while saying some true things can lead to harm in this way, it's more damaging to suppress or deny this information. How can it possibly be more damaging to forbid people from saying something inflammatory, like "Asians are smarter than Europeans" or "Europeans are smarter than Africans", than to allow it? Because the biggest gift you can give someone with a harmful agenda is something that looks to the untrained eye like a rational argument with solid empirical support, and then attempt to silence them.
You might bristle, but, according to studies I've seen, a white supremacist is not actually wrong when s/he announces that "Black people are on average less intelligent than white people!". What is wrong is the implication that they intend: that black people therefore deserve less respect/money/rights/something than do white people. As I see it, by trying to make discussion of the empirical data itself taboo, well-intentioned equality-minded people are only feeding the mistaken belief that, were there to be a genuine, measurable difference, the implication of being less deserving would follow. Not only is this false, it gives the supremacist more firepower: they can now truthfully claim, in addition, that "Liberals don't want this information to be known!".
One of the underexamined issues here is the special role of intelligence in the popular understanding of what it means to be human. We aren't threatened to the same extent by people drawing group-level distinctions based on, say, athletic ability. Our attachment to the idea of intelligence as central to humanity is, I believe, simply an unfortunate habit of mind. Fortunately, we're not totally governed by it: we don't put a murderer in prison longer if they murder someone highly intelligent. We already collectively agree that there are fundamental things to which we're all entitled based on nothing more than our humanity. (It's unfortunately true that there are many gaps and inconsistencies still in existence, but my point is that we aspire to treat people equally in these respects regardless of intelligence, and that in some cases at least, we achieve it.)
This is the right way forward, I believe. We need to create a widespread understanding that, even if average-level group differences exist in traits as beloved as intelligence, this would not imply anything about that person morally -- that is, about what that person deserves in life. With this in place, a supremacist's boasts about their race's intelligence have no more recruiting power than yelling out "Black people have darker skin than white people!" or "An object at rest tends to remain at rest!", or any other empirically demonstrable fact.
The first sentence in paragraph three of his Wikipedia page (http://en.wikipedia.org/wiki/Richard_Lynn) states that an experiment he conducted in the 1970s revealed North-East Asian people to have IQs on average 6 points higher than Europeans.
Certainly an interesting position for a person who "argue[s] for the genetic inferiority of non-white people" to prominently advocate.
Paragraph 3 of his Wikipedia page reveals that he considers North-East Asians to be about 6 IQ points more intelligent than Europeans, based on a study he performed in the 1970s.
So he would appear not to be as uncomplicated a racist as the parent comment implied. Which is a blow, to be sure; but I imagine that if we sling enough mud, some will stick, so there's hope for our noble smear campaign yet!
