Why do liberals despise facts, reason, and logic so?

>Discoveries using Magnetic Resonance Imaging (MRI), which creates a three-dimensional image of the living brain, have shown a strong positive correlation (.44) between brain size and IQ (see Rushton & Ankney, 1996, for a review). And there is more. The National Collaborative Perinatal Project on 53,000 children by Sarah Broman and her colleagues, showed that head perimeter at birth significantly predicts head perimeter at 7 years — and head perimeter at seven years predicts IQ. It also shows that Asian children average a larger head perimeter at birth than do White children who average a larger head perimeter than do Black children.

>Racial differences in brain size have been established using a variety of modern methods. Using endocranial volume, for example, Beals et al. (1984, p. 307, Table 5) analyzed about 20,000 skulls from around the world. East Asians averaged 1,415 cm3 , Europeans averaged 1,362 cm3, and Africans averaged 1,268 cm3 . Using external head measures to calculate cranial capacities, Rushton (1992) analyzed a stratified random sample of 6,325 U.S. Army personnel measured in 1988 for fitting helmets and found that Asian Americans averaged 1,416 cm3, European Americans 1,380 cm3, and African Americans 1,359 cm3. Finally, a recent MRI study found that people of African and Caribbean background averaged a smaller brain volume than did those of European background (again see Rushton & Ankney, 1996, for review).
