Nine things you should know about human intelligence and the race IQ gaps: (1) Human intelligence is a real thing and a scientifically valid construct. (100s of supporting studies.) (2) IQ tests measure intelligence well. (100s of supporting studies.) (3) IQ is strongly correlated with success in a wide variety of educational, economic and other desirable outcomes. (100s of supporting studies.) (4) IQ is moderately to highly heritable ("genetic"). (100s of supporting studies.) (5) Cognitive/IQ scores differ between population groups (such as "races"), sometimes significantly. (1000s of data sets and studies, and tens of millions of data points.) (6) The reasons for racial differences in IQ scores remain scientifically controversial, but the most recent comprehensive survey of scientists (the majority of whom were found to lean left politically) conducting research in this area found that an overwhelming majority of them believed that genetic differences between races play at least a partial role. (7) At every level of income and socioeconomic status, white Americans outperform black Americans on g-loaded cognitive testing (such as IQ tests), and, even more startlingly, the children of the poorest whites perform about the same as the children of affluent blacks. (Millions of data points.) (8) On those IQ tests that most accurately measure general intelligence (such as full-scale IQ tests), the score gap between whites and blacks has not meaningfully narrowed in over thirty years, despite gains by blacks in income and education. (9) The starkest difference between groups exists at the right tails of the IQ distributions (where the very brightest are located). For example, the percentage of persons with northeast Asian-ancestry living in developed nations who have IQs over 145 is over 400 TIMES greater than that of African-Americans. (On the left tail of the curve, the percentage of blacks who score below the IQ threshold for intellectual disability is at least 10 times higher than it is for Asian-Americans.)
