You do not understand the difference between being denounced and being disproved. How was Rushton debunked?
Actually, Rushton was disproved in that his methodology was faulty.
First, the skulls are of unknown gender, and the gender differences in skull size are at least comparable to those observed between races (women tend to have smaller brains, regardless of race; see criticisms by Cain & Vanderwolf,1990; Cernovsky, 1990, 1991). His tabular data are obviously of a dubious value, especially for the interpretation of possible racial differences in brains as differences in intelligence (men and women do not differ in intellectual skills even though they differ in average brain size).
Second, calculating an ANOVA on averages of subsamples instead of statistically using the original standard deviations of each subsample tends to artificially reduce the within-group variance. Because the ANOVA is a comparison of between-group and within-group variance, Rushton's procedure overestimates the magnitude and significance level of between-group differences in his data.
Third, as generally known, it is not sufficient to demonstrate a significant difference in aggregated data of racial groups in order to claim that this difference is genetic and to imply that it is relatively immutable. Rushton does do not provide credible and sufficient evidence in favor of genetic over environmental explanations for any of his alleged racial differences.
Well, I doubt it is, but even that chart shows that if you are richer, regardless of your race, you score better.Why is this true?
Not that I put any credence in any image you got off AmRen before they threw you off for thinking Jews were white.
