In the article above the following sentence is incorrect:
“Interestingly, at the same time as the influence of shared environment is diminishing, the heritability of intelligence increases, as first posited in the influential book chapter by McGue et al. (1993).”
It has been changed to:
‘Interestingly, at the same time as the influence of shared environment is diminishing, the heritability of intelligence increases (Wilson 1978, 1983).”
The original article has been resupplied both in PDF and HTML to reflect that. The authors apologise for the error.
