Date: August 21st, 2019 8:46 PM Author: magical crackhouse sound barrier In his 1995 book Race, Evolution, and Behavior, he alleged an average endocranial volume of 1,364 cm3 for East Asians, 1,347 for white caucasians and 1,268 for black Africans. Other similar claims were previously made by Ho et al. (1980), who measured 1,261 brains at autopsy, and Beals et al. (1984), who measured approximately 20,000 skulls, finding the same East Asian → European → African 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".[8] Rushton's findings have also been criticized for questionable methodology. Such as lumping in African-Americans with equatorial Africans, who generally have smaller crania as people from hot climates often have slightly smaller crania,[9] in craniometry studies. He has 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.[9] According to Zack Cernovsky, from one of Rushton's own study[10] emerges that the average cranial capacity for North American blacks is similar to the average for Caucasians from comparable climatic zones,[9] however a previous work by Rushton showed appreciable differences in cranial capacity between North Americans of different race.[11] This is consistent with the findings of Z. Z. Cernovsky that people from different climates tend to have minor differences in brain size. Though differences in size does not necessarily imply differences in intelligence. 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.[12][13] (http://www.autoadmit.com/thread.php?thread_id=4328006&forum_id=2#38722396) |

Date: August 22nd, 2019 12:53 PM Author: Flickering pozpig From Michael H. Hart "Understanding Human History': Last, but not least, are the differences in average cranial capacity and brain size between various racial groups. In general, Mongoloids have slightly larger brains than Europeans do, and blacks have much smaller brains than either. Racial differences in cranial capacity were measured by Samuel Morton over 150 years ago.31 However, in his influential book, The Mismeasure of Man, Stephen Gould insisted that because of Morton’s unconscious bias his measurements were incorrect. As a result of Gould’s assertions, many people think that there are no significant racial differences in brain size. However: 1) In 1988, John S. Michael remeasured the same skulls used by Morton and concluded that Morton’s work had been well done.32 2) Gould’s own measurements of Morton’s skulls showed substantial racial differences in average cranial capacity (87 cubic inches for Mongoloids and modern Caucasoids versus only 83 cubic inches for Negroes).33 In any event, more recent data — obtained from large samples, involving many thousands of individuals — show substantial racial differences. The exact figures depend on whether one: (a) measures the endocranial volume of skulls, or (b) measures the weight of brains in autopsies, or (c) estimates brain size from external head measurements of living persons, or (d) estimates brain sizes from MRI studies. However, all methods show that, on average, blacks have substantially smaller brains than whites or Mongoloids. Averaging across the various methods (and the two sexes) gives these estimates for average adult brain size:34 Mongoloids 1364 cc Caucasoids 1347 cc Negroids 1267 cc |
