• 73% of black babies are born out of wedlock. Source: National Vital Statistics Reports Births, 2010

• In 2012, the mean SAT critical reading score for college accepted students was 428 for blacks and 527 for whites. For mathematics, it was 428 for blacks and 536 for whites. For writing, it was 417 for blacks and 515 for whites. Source: National Center for Education Statistics

• The racial gap on the SAT is so large that the poorest white children, from families that earn less than $20,000 a year, do better than the wealthiest blacks, from families that earn 200,000 a year or more. Source: Journal of Blacks in Higher Education

Facts on the intelligence levels of blacks in America and around the world:

• Blacks have an average IQ of just 85, while white people have an average IQ of 100. Africans have an even lower average IQ score of 70-75. Higher IQ is a factor in causing people to not commit crime, to live longer and healthier lives, to earn more money, to perform better at every type of job, and to make better decisions. Source: Intelligence Predicts Health and Longevity, but Why?

• In a 2013 survey of top IQ researchers, 83% said that Africans were the least intelligent race in the world because of their genes. Source: Survey of Expert Opinion on Intelligence: Causes of International Differences in Cognitive Ability Tests

For people who claim that blacks' poor IQ scores are caused by poverty:

• In 1976, Harvard psychologists looked at how black children adopted by upper-middle class white American families performed on IQ tests. Black children adopted by white parents averaged 89 on IQ tests at age 17 (slightly better than the 85 average for blacks nationally). Since the black children grew up in white families with good socioeconomic conditions, only genetics can account for their low IQ scores. Regardless of wealth or environment, the racial IQ gap remains. Source: The Science of Mental Ability, pages 483-489

What if IQ tests are biased against blacks?

• There are IQ tests like the Raven's Progressive Matrices which don't have any language or words and rely entirely on visual pattern recognition. Even then there is a marked difference between black and white IQ scores, not only in America but internationally as well. In fact, the Black-White IQ gap has been observed in South Africa, the Netherlands, Canada, and many other nations around the world.

For people who say that race differences in IQ are just "white supremacy":

• IQ tests made by white people reliably show that East Asian countries have the highest IQ scores. African countries have on average the lowest. European countries are between the Asian and African countries, but are uniformly much closer to East Asia than to Africa.

IQ differences become more important at higher IQ levels:

• Overall, 18% of Asians have an IQ over 120, 10% of whites do and only 1% of blacks. Nearly 84% of blacks have an IQ below 100, which is slightly below the average IQ for whites. The ratio of white Americans to black Americans who have an IQ over 125 is 30:1. Source: Thirty Years of Research on Race Differences in Cognitive Ability

Blacks' low IQ scores is linked to their criminality:

• The average American criminal has an IQ 85, which is the exact same IQ score as the average black. Source: 21^st Century Criminology: A Reference Handbook

What academics have to say about black intelligence in their own words:

From the peer-reviewed paper The Totality of Available Evidence Shows the Race IQ Gap Still Remains:

The average IQ for African Americans was lower than those for Latino, White, Asian, and Jewish Americans (85, 89, 103, 106, and 113, respectively.

Our review of the literature shows that Black-White IQ differences in the United States have remained at 15 to 18 points, or 1.1 standard deviations, for nearly a century.

From the peer-reviewed paper Thirty Years of Research on Race Differences in Cognitive Ability:

The IQ gap between blacks and whites in the United States—15-17 points—has not changed since it was first measured nearly a century ago. Both races’ test scores rose during the century, but the gap remained as large at the end of the century as at the beginning despite considerable social change.

For those looking to pin the lower IQ scores of blacks on poverty, IQ is largely genetic. From the peer-reviewed paper Genetics and intelligence differences: five special findings:

Some evidence suggests that heritability might increase to as much as 80% in later adulthood but then decline to about 60% after age 80.

Why does IQ matter? From the article Social Consequences of Group Differences in Cognitive Ability:

Thousands of studies have looked at the impact of mental abilities on school and job performance, and large national longitudinal studies in both Europe and the United States have shown that IQ is related to various forms of socioeconomic success and failure.
