Summary
The study focused on the extent to which the general factor of intelligenceg and heritability coefficients of the subtests of an IQ battery correlate. Modest to strong positive correlations were found in five studies from Western countries and six studies from a Japanese meta-analysis. The results for Russian twins were compared with those of the Western and Japanese studies. Data from 402 twins aged 13 and 296 twins aged 16 showed correlations ofr=−0.45 andr=−0.60, respectively. It is concluded that the two data points are clearly not in line with established findings. It may be that the link betweeng loadings and heritabilities is more complex than previously thought.
