What an IQ test consists of can vary pretty wildly and specially in the U.S there's a lot more focus on the non-mathematical part as it tends to be an area where blacks don't do very well.
Well, given that on average Blacks are much poorer than Whites and receive much, much poorer educations, this can hardly be surprising. I mean unless you honestly make it your business to learn what they aren't teaching you in school, you simply aren't going to do very well on math, which is something that does need to be taught, for the most part (if it was easy to figure out by oneself, it wouldn't have taken mathematicians millennia to amass the proofs, theorems and algorithms we have today.) Extrapolating to poverty and education, I'd imagine Native Americans do even worse.
The tests I cited are part of the WISC/WAIS, which is the most commonly used test in the US. I don't know a great deal about the Stanford-Binet, but I believe it's of relatively similar structure. Those are the two most common by a very wide margin.
In most of the world it is basically mathematical aptitude because various cultural and language related factors can have an effect making the test more difficult for some and less difficult for others.
Which would make it more or less useless. My subtest score on the math section (verbal, mental math) was a 19, which correlates with a (subtest math IQ) of 150+. However, while my language, logic, reasoning and critical thinking skills are probably equally strong, my spatial abilities and visual memory are abysmal. Giving me a full-scale IQ of 150 would be silly.
For instance the PISA tests for the skills of school students can vary pretty wildly from country to country as the countries themselves are allowed to make changes to the tests to account for cultural differences. The end result of this is that not all tests are actually equal and kids in some countries have a slight advantage.
I agree that a lot of the school stuff ought to be removed. I remember taking it at 15 and thinking it was awfully stupid to have things learned in school (in this case, math, and I suppose general knowledge, though that *does* correlate nicely with intelligence) on the test. Though it's possible this was a bit self-serving as I was a D student with no ability to pay any attention whatsoever.
From what I've read you can get a lot of the difference ironed out by controlling the variables, but it doesn't completely obliterate the racial differences in average.
It actually does. They had to prime the Black test takers beforehand-- basically in order to raise their own expectations of themselves to that of Whites-- and this then erased the gap entirely.
This in my opinion lends credibility to intelligence being part nature and part nurture. However I'm pretty sure there are a lot of people, including scientists involved in this kind of research, who will not accept nature being any part in it because the very idea of one race having higher average intelligence than another race doesn't fit into their world view.
The truth is, of course, "race" is an entirely manufactured label (albeit a useful one). There isn't any biological distinction that validates the idea of race. Hell, we can barely decide on what constitutes a distinct species. The only reason we even have the idea of race is because we're human. Notice we don't apply it to any of the other (7.5-10) million species on the planet.
The term "Black" covers people from the 53 countries of Africa (as genetically diverse-- actually,
more diverse than the gene pool within Whites, e.g. Germans/Ashkenazi Jews/Irish/Scottish/Greeks/Spaniards etc.), not to mention Jamaica and Haiti. It wouldn't shock me if people of certain nationalities in Africa, or at least different regions were smarter than others in the least, but I would be
very surprised if the average of all people of African decent was lower (at least by more than a few tenths of an IQ point).
You'll remember we didn't depart Africa that long ago.
That said, of course IQ is very largely genetic. There just happen to be a myriad of other factors that can get in the way. (What I mean by this is that nutrition, education, lifestyle, stresses and upbringing can all have negative effects on potential. Unfortunately I don't know of anything that can actually increase potential
The point about race specific mutations was more just to prove that race does go more than skin deep, not to imply that genetics equal destiny or something else that's really far flung. As for the use of the asian flush as an example, I didn't say their liver couldn't process it, I said that they couldn't process it properly and clearly mentioned turning it into acetaldehyde, which causes the effects I mentioned. Producing acetaldehyde at a rate that causes those kinds of side effect is what I at least consider not being able to process it properly. I originally read the definition from my dad's old medical textbook when he showed it to me after the asian flush somehow came up when we were watching some Wong Kar Wai flick with the family.
Ah. My mother, I think, still has a medical textbook around somewhere, but it's so outdated we don't ever bother with it. Pretty sure my grandfather's would likely list hysteria as a real psychological/medical ailment. Best to avoid old ones from med school days
So basically it's just a you-know-what kind of redefinition of the word to suit an agenda?
Well, no. If that's how he was using the term, then what he said was true. I was merely pointing this out

That doesn't sound workable at all. You'd have too many categories to be able to draw general conclusions about IQ differences between races.
Untrue, of course. There are a lot of people in the US. Not twelve.
The 1996 Task Force investigation on Intelligence sponsored by the American Psychological Association concluded that there are significant variations in IQ across races.
Your assertion that it's been proven that there is "little to no performance difference between any of the races" doesn't stand up to scrutiny.
I'm not entirely sure how one twenty-year-old study, entirely without context, proves your point. (Your "link" to the study links to a quoted reply of your post.) Care to explain?
That said, you're a duck. What do you know.
