Population of Blacks/Whites in US by IQ
- Thread starter George S
- Start date
In a book reviewed in the Economist this week it is pointed out that the rise in IQ in the US since 1945 is produced by better food and better education. Give 'Black' people those given to the top 1% of your population and see what the figures are after twenty years, particularly if you fix the tests to reflect their experience as they do now for 'whites'.

IQ tests are remarkably race neutral these days. And have been for the entire lives of the 1980-1990 cohort tested. The Head Start program has been going long enough so that there is data. You won't believe me, so check it out. (hint: you may find that the head start didn't help in the long run.)
Cautionary note: No individual is to be judged by his or her race. Not all blacks have an IQ of 85. Not all whites have an IQ of 100. There are always outliers. It may be useful data to understand why quotas by race are wrong. Quotas by sex are equally wrong. The races are actually different in other ways than skin shade. The sexes are differently enabled too. In a similar vein violent crime peaks at 85 IQ regardless of race. This does not mean that all blacks are criminals.
Can you provide data more recent than a graph based on AFQT scores from 1980?

Here's more current data from Stefan Molyneaux's The Truth About Crime (https://youtu.be/TVBJ5m3sGfk?t=38m51s).
Which, in turn, provides the following:
If you take these graphs and weight them by population you get a current graph quite similar to the longitudinal study data.

None of those sources provide the data for Molyneux's IQ graph; he plagiarised it from this graph that appears to be sourced from

Can you provide a more reliable source?
Well, the IQ/intelligence differences among human population groups is one of those things we all know but don't like to talk about. Take for example, PISA scores from 2012.
Asian-Americans tend to do as well as, Asians.
White Americans tend to do as well as, Europeans.
And Black Americans tend to as well as, . . . perhaps better than any black majority country.
Anyway, though this indicates a relationship between population groups and IQ - after all, your population group is really just your hyper-extended genetic family - ultimately what matters is the population group of two, your parents.

Actually, new science indicates IQ comes primarily from the mother.

Given that the majority of old white males and only 1% of blacks support Trumples, I'd intuit that blacks are a lot smarter than old white males... IQ test results be damned!
(FWIW, as a kid with "behavioral and performance problems" in grade school, I was administered so many IQ tests that I became a veritable expert in IQ test scoring, putting up numbers in the 160s by the time I was in seventh grade. Those numbers have virtually ZERO correlation with actual functional "intelligence". Believe me!)

What is a "black"?
Scientifically not subjectively.
Maybe something genetic?
In these IQ studies how many people have been genetically tested?
And what exactly is a passing test for "black"?

In this context it's a subjective and somewhat arbitrary assignment based mainly on the apparent melanin levels produced by an individual's skin.
Sorry - AFAIK there is no purely scientific means of assigning an individual as black or white or red, yellow or brown. I could be underinformed...
One could definitely assign genetic profiles to the color categories, but they would be largely arbitrary assignments.
Skin with either "lots of" melanin, or covered with some dark pigment. Don't believe me? Try going the dark pigment route, and see how you are judged!

When we have a scientific definition of "black" we might be able to say something about it.

Right on. Meanwhile, we can continue to say "because I said so" and the like. Races are to racists as religions are to believers - whichever one you identify with is The Best™.

If by "black" you mean "Negroid", it means most of the individual's ancestors 30,000 years ago lived in Sub-Saharan Africa.
Get your genome sequenced and compare it with Yale Medical School's online database.
As with all applications of our digital languages to an analog world, passing scores are a matter of taste. To me it seems silly to pick a number other than 50% as the passing score. YMMV.

When I entered the RAF they gave us an IQ test, and thereafter all the RAF could ever find to say in my favour was that I was 'remarkably intelligent', which is what first made me dubious about the whole concept
. At absolute best, surely, such tests decide only what are the characteristics smiled on and likely to lead to 'success' in particular societies? I think that as they adjust the things to answer one particular criticism they open themselves to a hundred more. They are just a new technique to make ideological justifications for masters and servants, now the Word of the Lord doesn't carry as much conviction as was wont.So do IQ tests account for differences in income levels, social discrimination, robustness of economy, environmental differences, religiosity, quality of education systems.. etc etc etc etc.
You can't take person A with economic and environmental deficiencies, give them a test, and expect them to do as well as a white kid eating a plate full of vegetables, chicken, and who is going to go play xbox after dinner. The playing field is just not the same.
When someone can normalize for environmental factors, I'll be listening.

Scientifically there is no such thing as a "white" kid.
