    Jensen's own research suggests that IQ tests amalgamate two forms of thinking which are hierarchically related but which become differentially distributed in the population according to SES: level 1 and level 2, associative learning and abstract thinking (g), respectively.

    [31] [32] Not all report test results as "IQ", but most now report a standard score with a mean score level of 100. When a test-taker scores higher or lower than the median score, the score is indicated as 15 standard score points higher or lower for each standard deviation difference higher or lower in the test-taker's performance on the test ...

    On measures of cognitive ability (IQ tests) and school performance, black children in the U.S. have performed worse than white children. At the time of the study, the gap in average performance between the two groups of children was approximately one standard deviation, which is equivalent to about 15 IQ points or 4 grade levels at high school graduation.

    Stressing the similarity of average IQ scores across racial groups in the Eyferth study, James Flynn, Richard E.

  9. Heritability of IQ - Wikipedia

    en.wikipedia.org/wiki/Heritability_of_IQ

    [1] [2] Intelligence in the normal range is a polygenic trait, meaning that it is influenced by more than one gene, [3] [4] and in the case of intelligence at least 500 genes. [5] Further, explaining the similarity in IQ of closely related persons requires careful study because environmental factors may be correlated with genetic factors.
