IQ Distributions

The respective IQ distributions of any given races will show overlap. Height distributions among males and females also overlap (height is about 80% heritable; IQ is about 75% heritable).  

Among all people in the U.S. with IQs below 75, there are more blacks than whites.  Among all people in the U.S. with IQs above 100, there are several times more whites than blacks.


We shouldn't be surprised or morally outraged that in professions requiring high-level mental functioning, blacks will be relatively scarce absent Affirmative Action interventions. Denial of racial differences in distributions of cognitive capacity will tend to foster surprise, moral outrage, and demands for Affirmative Action in response to what is natural and entirely predictable.

  1. Librealist,

    What do you make of the UK differences?

    2. Hi Lib-Realist,

      I was somewaht upset (though not surprised) to hear that the YouTube police deleted your account. It must have been all the more upsetting for you to get the news.

      Unfortunately, people who think the way we do are part of a very small online community. It would be a real blow to lose someone like you -- a sensibly-oriented thinker on racial topics, who takes the take to inform others with good digital content.

      I write now only to encourage you to continue to do your thing. I think there must be others, just like me, who are anonymously appreciating what your work.

      With sincere thanks!

    3. Yes, the reason his account was deleted was for unsubstantiaTED NONSENSE. According to Gotfredsson wed have so few blacks at university it would be a whitewash, the truth is there are far too many blacks attending across the world for her work to be true. Anyone with a good knowledge of Maths will take one look at the above and laugh. That is why this material gets nowhere... its just racist pseudoscience, and Im betting no many here supporting this material are of any educational note either.

    5. Too bad your mom didn't inadvertently miscarry you by overdoing the fetal alcohol she clearly started on, you knuckle dragging ape.

    6. "knuckle-dragging ape . . . how inferior darkies are . . . "

      Oh, just join the Neo-Nazis in protesting the takedown of statues dedicated to Confederate traitors already.

      Libertarian Realist should just rename himself Race Realist, and then we'll have a more accurate sense of what this violently stupid website is really about:

      "Black racial justice warriors such as Ta-Nehisi Coates . . . Affirmative Action babies who have been politically moly-coddled [sic] their whole lives with . . . generous handouts paid for by white tax dollars."

      Yap. That's the first paragraph of Race Realist's third-most popular article, satirically titled "The Case for Reparations," after Coates's tour de force exploring the history of institutional racial discrimination that violently forced black Americans down for centuries, a phenomenon that will take far more than the mere half-century since the passage of the Civil Rights Act to correct.

      (Coates never went to college, and so could not have received preferential admission. Nevertheless his aforementioned tour de force is simply out of this trashy blog post's league. Eventually, stupid people such as yourself will have to stop confusing various confounding factors such as educational opportunity, income inequality, and built-in exam bias that produce apparent disparities in IQ scores with "lol see facts prove darkies are dum u politcly corect libturds.")

  2. Could you post the year of that graph or similar and age distribution, with a source for the individual IQ bins? I want to do a deconvolution on the IQ distribution, so I need the proportional weights for each IQ (or quarter IQ---even better) to account for known environmental causes, e.g. lead (paint, gasoline), mercury (skin whitening creams sold in US until 2008).

  3. Compared to Ashkenazy Jews, you people are all submental. You should spend your time hunting or riding ATVs and let the grownups make the decisions.

    1. LR always says that Eastern European Jews and Asians are more intelligent than White European Christians. It doesn't offend him and neither should any statistic offend any sane person. See what I'm getting at? You are not one of the sane people I'm referring to.

  4. And if the above Anonymous had a discernible IQ, he/she/it would know the definition of "submental," and the correct spelling of Ashkenazi.

  5. How about the distribution of intelligence in e.g., dogs of different breeds?

  7. I tried to find the source of the first bell curve image. According to bls.gov, they did test IQ in the NLSY79 1980 high school survey. But, the actual data seems to not be readily available. One thing to take into consideration is that poverty has significant consequences on cognitive ability, crime, etc. Largely due to the history of discrimination, minorities are disproportionately affected by poverty. So, studies comparing things like IQ need to control for such factors.
