The biometrical school of scientists who fit models to IQ data traces their intellectual ancestry to R. Fisher (1918), but their genetic models have no predictive value. Fisher himself was critical of the concept of heritability, because assortative mating, such as for IQ, introduces complexities into the study of a genetic trait. (SLD)

The estimation of genetic models reported by J. L. Jinks and L. J. Eaves in a recent review are critically examined. A number of errors in procedure and interpretation are found. It is concluded that the evidence, provided by kinship correlations, for the proposition that intelligence is highly heritable, is not persuasive. (Author/BJG)

An adaptation of the multiple regression approach of De Fries and Fulker (DF analysis) is used to account simultaneously for genetic and environmental influences on achievement. The model was fitted to achievement measures of 1,044 related pairs of children from the National Longitudinal Study of Youth (NLSY). (SLD)
