We review recent research which estimates racial differences in cranial capacity by measuring head dimensions of living persons. We describe errors in published reports, and find that American whites have greater head height than American blacks, but that blacks have greater head length and greater head circumference. Estimates of cranial capacity are determined by racial differences in head shape. Possible relations between head size and measured IQ are so small that they cannot possibly…

It is demonstrated that differences among social groups in terms of cognitive ability are largely illusory, because these group differences are contextually dependent and reflect the social context in which they are assessed rather than any real intrinsic differences.
Racial Disparity Between Asian and Caucasian Crouzon Syndrome in Skull Morphology.
Crouzon syndrome causes a shortened, widened, and kyphotic cranial base across both races, however, the skull malformation is not the same between populations: Asian Crouzon patients developed more narrowed Cranial base angulation on the intracranial side of basicranium, while Caucasian Crouzo patients develop more widened lateral pterygoids.

Further evidence for the existence of race and sex differences in cranial capacity
Cranial capacities were calculated from the external head measurements reported for 36 samples of 7 to 15 year olds gathered by the Philadelphia Growth Center (Krogman, 1970). The core sample
Brain size and cognitive ability: Correlations with age, sex, social class, and race
It is clear that the direction of the brain-size/cognitive-ability relationships described by Paul Broca, Francis Galton, and other nineteenth-century visionaries is true, and the null hypothesis of no relation, strongly advocated over the last half century, is false.
