Rushton on 30-years of Research on Intelligence. IQ. East Asians 106 Whites 100 U.S. blacks 85 African blacks 70. True-false. real-fake?

1. The Worldwide Pattern of IQ Scores. East Asians average higher on IQ tests than Whites, both in the U. S. and in Asia, even though IQ tests were developed for use in the Euro-American culture. Around the world, the average IQ for East Asians centers around 106; for Whites, about 100; and for Blacks about 85 in the U.S. and 70 in sub-Saharan Africa.

2. Race Differences are Most Pronounced on Tests that Best Measure the General Intelligence Factor (g). Black-White differences, for example, are larger on the Backward Digit Span test than on the less g loaded Forward Digit Span test.

3. The Gene-Environment Architecture of IQ is the Same in all Races, and Race Differences are Most Pronounced on More Heritable Abilities. Studies of Black, White, and East Asian twins, for example, show the heritability of IQ is 50% or higher in all races.

This data is Now public. Public in the Public Domain. Are the numbers true-false. Real-fake.
Can we rely on the numbers as true?

  1. It is irrelevant. What difference will it make to society?
