Black IQ

The mean black IQ in America now stands at 89.1, according to the WAIS-III IQ test. For whites it is 102.6. That is a difference of 13.5 points. Other tests show the same kind of difference. So do university entrance tests, which makes it a serious issue.

But it gets worse.

The differences are not where you would expect: in the use of words and numbers where poor education could bring down scores. In fact, when it comes to words, numbers and memory, blacks do about as well as whites. Where blacks do worst is on the questions that require reasoning, in thinking something through!

Now know this: the IQs of twins separated at birth are different by only 6 points or so. So whether you grew up rich or poor, went to good schools or bad, it will only affect your IQ by about six points.

That means racism, poverty, bad schools and all that can only account for half of the 13.5 point difference between blacks and whites.

This difference does not square with my own experience, but then I do not know white people as a whole or black people as a whole.

I always thought it was because white people wrote the tests. Some of the older tests were unfair like that, but with the newer ones no one has been able to prove that it makes any difference for blacks who can speak and read English. In fact the tests work all too well: a low IQ means you will do less well in school, and that turns out to be just as true for whites as for blacks.

But when people try to prove blacks are born with less intelligence, it gets strange:

  • Light-skinned or whiter-looking blacks do not have higher IQs than darker, blacker-looking ones.
  • For blacks brought up by white parents the difference is small: three points or less.
  • The difference does not appear right away, like you would expect for something you were born with. It comes out during the school years.
  • The difference has been getting smaller over the past 30 years. It used to be 15 points.

There are enough strange facts pointing in different directions that you can make whatever argument you want about why black and white IQs are so different. We simply do not know enough yet. We have not found the smoking gun. Or the right way of thinking about it.

If we understood the Flynn Effect we might know what is going on. The Flynn Effect is where IQs in rich countries have been slowly rising. In America they have risen by 15 points in the past 50 years. That makes blacks living now as smart as whites from the 1950s, but whites smarter still.

No one knows what causes the Flynn Effect, but it shows up in the very part of the IQ test that blacks do badly in: the reasoning part. And it affects mainly those with low IQs, which is why blacks have been catching up. So understanding it might be the key.

IQ (1905- ) is short for intelligence quotient. It is a way to measure intelligence. IQs go from 0 to about 200. Most people have an IQ near 100.

To give you a rough idea of what the numbers mean in English:

0 to 70 retarded
70 to 90 dull
90 to 110 average
110 to 130 bright
130 to 200 gifted

Most maids have IQs of about 100, professors about 115 and doctors 120. To join Mensa you need an IQ of at least 130.

IQ = (mental age / calendar age) x 100

If you are over 16, then your calendar age is just 16. It does not go higher than that.

To find out your mental age you take an IQ test which compares how well you did on its questions compared to people of different ages.

So, for example, if you are ten years old but did as well on the test as an ordinary 12 year old, then your IQ is (12/10) x 100 or 120.

Or: if you are fully grown but have the mind of an 8 year old, than your IQ is 50: (8/16) x 100.

So when Steve Sailer says that ordinary black Americans have an IQ of 85 he is saying they have the mind of 13-year-olds (= 16 x 0.85). That is why he says they need “moral guidance” and why black Africa will always be in a “Lord of the Flies” mess unless it is ruled by outsiders.

On the Internet you can find terrible IQ maps of the world. I do not know where they get their numbers. Most go something like this:

  • 105: China, Korea, Japan
  • 100: Europe, Russia, North America, Australia, Argentina
  • 85: Latin America, Middle East, India, South-east Asia
  • 70: Black Africa

Yellow, white, brown and black, in that order, it seems.

If you took the SAT before 1995, the test you need to take to apply to American universities, you can get a pretty good idea of your IQ: it is about one tenth of your combined math and reading score. So if you got 550 math and 630 reading (verbal), your combined score is 1180 and your IQ is most likely somewhere near 118. That is no accident. The SAT grew out of the old IQ test that the army used.

Here are the estimated IQs of some famous people:

  • 195: Pascal
  • 190: Newton, Voltaire, Kasparov, Wittgenstein, Laplace
  • 185: Galileo, Descartes, Bobby Fisher
  • 180: Michelangelo, Lord Byron
  • 175: Kepler, Kant, Spinoza
  • 170: Plato, Luther, Raphael, Wagner
  • 165: Darwin, Hegel, Beethoven, Mozart, Bach, John Locke
  • 160: Einstein, Bill Gates, Hawking, Ben Franklin, Isaac Asimov, Reggie Jackson
  • 155: Balzac, Sharon Stone, Cervantes, Rembrandt, Swift, Emerson
  • 150: Rousseau
  • 145: Napoleon, Nixon
  • 140: Hitler, Hillary Clinton, Madonna, Shakira, Jefferson, Geena Davis
  • 135: Arnold Schwarzenegger, Al Gore
  • 130: Jodie Foster, Lincoln
  • 125: George Bush
  • 120:
  • 115: John Kennedy
  • 110: Ulysses Grant
  • 105: James Watson
  • 100:
  • Less than 100: Andy Warhol (86), Muhammad Ali (78 )

IQs have been going up in rich countries over time, about a point every three years. This is called the Flynn Effect. No one knows for sure what causes it.

It would help if people understood just what it is that IQ tests test. It is not intelligence but something like it – whatever it is that makes some children do well in school and others do poorly. That something is not what Edison, Warhol, Picasso or Churchill had, yet no one ever doubted their intelligence after their school years.
