A Simple Exposition of Jensen’s Error

Roger Milkman

Journal of Educational and Behavioral Statistics, 1978, vol. 3, issue 3, 203-208

Abstract: Jensen (1969 , 1973) has used within-population heritability data to support his contention that IQ differences between races have a considerable genetic basis. Criticism of this reasoning has been frequent, but perhaps never categorical. A method is now described for illustrating the error simply and quantitatively. An example shows that high heritability of a property within each of two populations is consistent with a vanishingly small heritability in the combined population.
