The best part is his pointing out that self-described hereditarian Gregory Clark uses the "classic" heritability (as opposed to "molecular") method invented by racist Francis Galton to make claims about social success and genes.
I will point out again that the Adam Rutherford co-authored paper cites Clark three times to make its arguments.
In case there is any doubt how extreme are the hereditarian claims being promoted by Adam Rutherford, Abdel Abdellaoui and their eight co-authors.
