Black mean IQ: 85
Obama's IQ: 140

These statements are not exclusive or contradictory.
I suggest a refresher course in statistics.

So, what is the mean IQ for White in the USA?

I think the mean IQ is a meaningless mean, since the African Americans are not homogeneous (single Black), there are different blacks with different backgrounds which makes the mean IQ not reliable. Also, if you take each state separate, do you think you will get the same mean IQ for the African American population?

East Asian-105
White-100
Hispanic-90
Black-85

Mean is a form of shorthand for a population. Helps to look at variation as well. 25%of Blacks have an IQ around 70 while another 25% have IQ scores around 100 (the mean for Whites).

Yes, Obama is a bright, articulate (half-)Black man. He did very well on the LSAT. That is why his inaccurate criticism of the book The Bell Curve is so strange; the test-based admission system is what allowed bright folks like Obama get into elite universities.

He is, however, an extreme outlier. A unicorn.

Yup, 20 years later, the battles rages on. Genetics research is finding more evidence that intelligence is heritable, while the environmental crowd is finding disparities of opportunities. Both are correct. It is not nature OR nature, it is nature AND nurture working in tandem.

Right after TBC came out, some academics (ahem) published this load of crap, chock full of bad argumentation.

That Slate article was better.

What is the IQ score for Trump the trumpet?
Some say his IQ is around 156!!!
Woww, this makes him smarter than 99.987% of the American population?

But wait, what is the story behind his IQ? Is it because he graduated from Wharton Business School at the University of Pennsylvania. But he did not take the MBA course. So was his IQ test based on Wharton's admissions requirements?
Did he go through the usual admissions process ? No.
Did he make the 'Dean's List'? No.
Did he graduated with honours? No.
So.. how come he got an IQ of around 156?
Is he genetically modified to get that IQ? May be! Laughing

Ok, let assume he has an IQ between 120 and 130, does this make him genius? No.

Is he a politician or a comedian? Let the American people answer this question!

And here is what Trump is saying about his IQ:
"Sorry losers and haters, but my I.Q. is one of the highest -and you all [url]know it! Please don't feel so stupid or insecure,it's not your fault"
https://twitter.com/realdonaldtrump/status/332308211321425920?lang=en-gb&lang=en-gb[/url]

Who are the losers and haters, Mr Trump? Laughing

Some of the debate surrounding the biological basis of IQ focuses on differences in test scores between racial groups. Yet, these differences, such as those between African-Americans, Hispanics, and Whites, are shrinking. In the 1970’s, African-American IQ scores averaged a full standard deviation (15 points) below the average for Whites, with Hispanic scores falling somewhere in between the two averages. Since then, test scores for African-American and Hispanic groups have gradually risen, even outpacing the Flynn effect.
We do not yet know how to define human intelligence.
BRIEF ON INTELLIGENCE AND GENETIC DETERMINISM
Council for Respectable Genetics

There are a number of points to consider when interpreting heritability:

    * Heritability measures the proportion of variation in a trait that can be attributed to genes, and not the proportion of a trait caused by genes.
    * A common error is to assume that a heritability figure is necessarily unchangeable.
    * A high heritability of a trait does not mean that environmental effects such as learning are not involved.
    * Since heritability increases during childhood and adolescence, and even increases greatly between 16–20 years of age and adulthood,
    one should be cautious drawing conclusions regarding the role of genetics and environment from studies where the participants are not followed until they are adults.
--Wikipedia

Who are these people taking the IQ test for the researchers? What is the research method used? Without this data interpretation is pointless.
