Right, but you presented in the crudest way possible. Also, do you have any empirical criticisms of the claims?

Oh come on. You've surely seen much cruder (probably today alone). My critique focuses on the chain of reasoning--not any one claim, but how you put them together--and on overrating how much small observed differences in large populations can explain individual variation.

The chain of reasoning you cite does not appear in the article. "Skull shape correlates with race, which correlates with IQ, which measures intelligence, so skull shape can predict intelligence."

Exactly. Thank you.

1) Offers phrenology as example of a shunned course of study that may have scientific value 2) Notes that new evidence shows skull shape correlates with race 3) Defends studying biological correlates of race because observed IQ gap could be caused by biological or social factors

We didn't do 1, 2 is not a new article, and 3, yes, I think we should study differences in IQ and their cause. Surely, you would want to know if it were caused environmentally or genetically?

I sincerely wish I had not included that passage. The only point was that phenotypic variation is correlated and that humans can classify it reasonably well.
