. Measurements were first made to compare the skulls of men with those of other animals. This wide comparison constituted the first subdivision of craniometric studies. The artist-anatomist Camper developed a theory to measure the facial angle, for which he is chiefly known in later anthropological literature. Camper's work followed 18th-century scientific theories. His measurements of facial angle were used to liken the skulls of non-Europeans to those of apes. "Craniometry" also played a role in the foundation of the United States and the ideologies or racism that would become ingrained in the American psyche. As John Jeffries articulates in ''The Collision of Culture'' the Anglo-Saxon hegemony present in America during the eighteenth and nineteenth century helped establish "The American School of Craniometry" which helped establish the American and Western concept of

John Michael found Morton's original data to be more accurate than Gould describes, concluding that " ntrary to Gould's interpretation... Morton's research was conducted with integrity." In 2011, physical anthropologists at the University of Pennsylvania, which owns Morton's collection, published a study that concluded that almost every detail of Gould's analysis was wrong and that "Morton did not manipulate his data to support his preconceptions, contra Gould." They identified and remeasured half of the skulls used in Morton's reports, finding that in only 2% of cases did Morton's measurements differ significantly from their own and that these errors either were random or gave a larger than accurate volume to African skulls, the reverse of the bias that Gould imputed to Morton.

pattern. However, in the same article Beals explicitly warns against using the findings as indicative of racial traits, "If one merely lists such means by geographical region or race, causes of similarity by genogroup and ecotype are hopelessly confounded". Rushton's findings have also been criticized for questionable methodology, such as lumping in African-Americans with equatorial Africans, as people from hot climates generally have slightly smaller crania.Cernovsky, Z. Z. (1997)A critical look at intelligence research, In Fox, D. & Prilleltensky, I. (Eds.) Critical Psychology, London: Sage, ps 121–133.
/ref> Rushton also compared equatorial Africans from the poorest and least educated areas of Africa against Asians from the wealthiest and most educated areas of Asia and areas with colder climates which generally induce larger cranium sizes in evolution. According to Zack Cernovsky, from one of Rushton's own study it emerges that the average cranial capacity for North American blacks is similar to the average for Caucasians from comparable climatic zones. Per Cernovsky, people from different climates tend to have minor differences in brain size, but these do not necessarily imply differences in intelligence; for instance, though women tend to have smaller brains than men they also have more neural complexity and loading in certain areas of the brain than men.
