人们常常断言，美国黑人的智商并没有比美国白人高。直到最近，还没有足够的数据来衡量黑人智商的趋势。我们分析了四个主要认知能力测试的九个标准化样本的数据。这些数据表明，1972年至2002年间，黑人的智商比非西班牙裔白人高出4到7分。在整个黑人认知能力的范围内，进步是相当一致的。
It is often asserted that Black Americans have made no IQ gains on White Americans. Until recently, there have been no adequate data to measure trends in Black IQ. We analyzed data from nine standardization samples for four major tests of cognitive ability. These data suggest that Blacks gained 4 to 7 IQ points on non-Hispanic Whites between 1972 and 2002. Gains have been fairly uniform across the entire range of Black cognitive ability.
