Original sentence: (Gould 1981: 127; 156-156).Jensen has used the concept of heritability to measure differences in inheritance between populations, and this is the basis of the criticism.Secondly, Gould disagrees with Jensen's belief that IQ tests measure a real variable, g, or "the general factor common to a large number of cognitive abilities" which can be measured along a unilinear scale.Third, Gould disagrees with Jensen's support of the attempts of others to calculate the IQ's of dead people (such as the famous Polish astronomer and Prussian monetary theorist Copernicus) (1981: 153-154)
Edited sentence: Jensen, however, has used the concept of heritability to measure differences in inheritance between populations (Gould 1981: 127; 156-156).The second criticism is relatively minor: Gould disagrees with Jensen's support of the attempts of others to calculate the IQ of dead people (such as the famous Polish astronomer and Prussian monetary theorist Copernicus) (1981: 153-154).The third criticism is significant: Gould disagrees with Jensen's belief that IQ tests measure a real variable, g, or "the general factor common to a large number of cognitive abilities" which can be measured along a unilinear scale
