Sort of. This paper is famous but no one has done a proper follow-up, and I couldn't find a copy of their dataset for re-analysis. :( …https://lesacreduprintemps19.files.wordpress.com/2011/05/smith-beals.pdf … It is now possible to do these checks using DNA from old bones, like this paper https://www.ncbi.nlm.nih.gov/pubmed/28724479
Great new study on the causality of brain size for intelligence. Given the historical record, one would have to be obtuse to deny this causality, but Nisbett did it anyway based on n=36 sibling study because doubt is his product. https://www.gwern.net/docs/iq/2019-lee.pdf …pic.twitter.com/aFxrLQXHpU

It's been tested with respect to the cranial bumps stuff, and that didn't work. The brain shape etc. probably works, especially smaller variations in shape will work well.https://www.sciencedirect.com/science/article/pii/S0010945218301436 …

I'd love to hear your thoughts about this new study on Cerebral Surface Area: http://www.jneurosci.org/content/early/2019/03/01/JNEUROSCI.2248-18.2019 … "there’s almost perfect genetic overlap between IQ and surface area in that spot [supramarginal gyrus on the left side of the brain]... The correlations are almost one"

How do we know that proficiency in the intellectual tasks involved in measuring general intelligence secures significant evolutionary advantages?
