I think this discussion should be limited to the skell of the skull and not generalizations about intelligence.
As far as I can tell, Morton did believe in the intellectual superiority of whites. Whites versus Asians, for instance. Nuff said.
Looks like what Gould got wrong was his claim that Morton used cranial volume to support the contention of white intellectual superiority.
Gould wrote his book to discredit any thoughts of gene-based differences in intelligence. He was a fraud, and used the phony argument about skull size to set up a straw man. So, we differ...I believe it is quite relevant.
