Nope, that's not how I'm using "foil-seeker". I'm using foil-seeker to describe someone who wants to reduce any discussion on possible differences in abilities between human populations into a binary debate, with the foil-seeker defending the position that all human populations are equal in ability, and the foil claiming that human populations vary in ability. In particular, the foil seeker usually wants the debate to be against some poor shmoe with the harijan's job of claiming that "white people" are genetically more intelligent than "black people". Why not just make those dupes handle dead bodies and human waste, like they do in more transparent societies?
It's fine if one is actually accomplishing a utilitarian end, like keeping social resources from flowing to pyschics or people that put segregation above free market resource liquidity. But this type of foil-seeking is wasteful when it retards intelligent exchange of ideas which can expand general enlightenment. And I think that does happen on this topic of human populations and differences in ability.
Yes, it's a perennial problem. There are two fallacies at work here: strawperson and corruption of the continuum.
1. Strawperson, in that there's the implication that anybody who accepts that there are races is also an advocate for some sort of heirarchy. This is a complete fabrication, and very insulting, to boot. It only serves to draw the debate into insults. Most people quite readily identify races in general, with some local cultural spin, and it's not usually associated with a belief in inherent abilities.
2. Corruption of the continuum, in that just because there isn't a discreet cutoff point between races doesn't mean they aren't useful socially or biologically. As pointed out above, the entire field of zoological phylogeny is a human construct, and it's very useful. The fact that biologists as a community are using the binomial system instead of the clade system is social or even just historical inertia, but the end result is that we have a system that bears fruit.
My impression is that Yahzi, Wudang, joobs, and perhaps even Wade1001 are in what I would call the 'race denialist' camp. This is a group that was curioius a few years ago, but has grown in popularity recently and I'm starting to percieve them as a threat.
Basically, it boils down to this, in my opinion: a bunch of white racists observed that blacks were getting compensated for centuries of mistreatment. They found that the best way to put an end to this was a two-pronged attack: claim that racial favouritism in the form of affirmative-action is unconstitutional and discriminatory, and secondly, argue that it's morally questionable, because there's no such thing as race anyway, and it can only be exercised by labelling. The great thing about the latter argument is that it was picked up by a bunch of white males in universities so they could show how broadminded they were, and has the veneer of moral highground. It is not the moral highground: it is doing the Klan's handiwork. The only people who say race doesn't exist are comfortable white people who aren't impacted by the consequences of such beliefs.
That's why I laughed when I read Cuddles' comment:
As I said, all people should be treated equally and considered equally, but this does not mean they are all the same, no matter how much the PC movement tries to claim this.
Whenever I see the label "PC movement" applied, I interpet that to read "The poster has turned off his brain today." PC is an expression that is tossed out to insult people with a differing point of view. If you believe races are a sensible terminology, you believe the PC movement is trying to eliminate the concept of race so everybody's the same. If you believe race is not a sensible terminology, you believe the PC movement is trying to preserve the concept of race in order to draw compensation or sympathy. Like antisemitism, antiPCism constructs a bizarre conspiracy that seems to be behind opposing activities!
Anyway, that's my rant on the subject. Here's the meat:
1. The concept of race may be fuzzy and social, but it preserves bilogical utilitiy, as does many scientific concepts. Denying the existence of races is ridiculous.
2. IQ testing is probably the best indicator of intelligence that we have, so in the absence of an alternative, I am satisfied that it can be used as a proxy. Sure, there's a history of abuse, but criticism of current tests is questionable.
3. IQ scores do show differences between races; however, given that there are no experiments that can control for important factors, the origin of this difference could be social, biological/nongenetic or biological/genetic, or a mix of the three influences. Any claims of certainty for one or the other are premature.
