“The hip-hop culture is sinking its teeth into a new fashion trend. Individual gold-capped teeth have given way to grills and fronts — removable mouthpieces made of gold, platinum or silver and sometimes studded with jewels.”

“… much of the opposition to IQ testing and heritability would probably disappear if it were not for the stubborn and unwelcome fact that, despite extensive well funded programs of intervention, the Black-White difference refuses to go quietly into the night. Chapter 11 of The g Factor fully documents that, on average, the American Black population scores below the White population by about 1.2 standard deviations, equivalent to 18 IQ points. (This magnitude of difference gives a median overlap of less than 15 percent, meaning that less than 15 percent of the Black population exceeds the White average of 50 percent). The difference between Blacks and Whites in average IQ scores has scarcely changed over the past 80 years (despite some claims that the gap is narrowing) and can be observed as early as three years of age. Controlling for overall socioeconomic level only reduces the mean difference by 4 IQ points.”

If Professor Jensen is correct, Blacks in America have an average IQ of ( 100 - 18 +4 ) = 86 and half of them have less than an 86 IQ.

“Fifty years after a landmark Supreme Court decision began the desegregation of U.S. public schools, educators, parents and students are struggling to close the academic gap between white and African-American students.”
“The schools in Shaker Heights, outside of Cleveland, Ohio, are nationally known for academic excellence. But as in many schools in the nation, a significant disparity exists between black and white students' achievement.
A school-sponsored study in 1997 found 82 percent of the students who failed proficiency tests were black and the average SAT score for black students was 305 points lower than the average for white students. The findings rocked the community and spurred parents to seek answers.”
