This was published seven years ago. Its arguments are very sketchy - as if settling nurture versus nature for humans were not social science, as opposed to science.

If identical twins are raised in a wealthy household versus a poor household, how can one determine traits coming from inheritance versus environment? This analysis does not really answer it.

The data of identical twins separated at birth is very light, as one can imagine. A look at the data of the major studies shows there really is not a lot of data - twins are separated at the age of 9 or so, or sometimes are separated at birth and then reunited.

Many of these twin studies are funded by the strange but well-funded Pioneer Fund. You can check out what they were up to in the 1930s if you're interested.

Interesting coincidence, but I'm guessing you were referring to

> an American non-profit foundation established in 1937 "to advance the scientific study of heredity and human differences".

> The organization has been described as racist and white supremacist in nature.
