The Real War on Science

The Real War on Science
Seven impossible ideas before breakfast. "The Blank Slate dogma has perpetuated a liberal version of creationism: the belief that there has been no evolution in modern humans since they left their ancestral homeland in Africa some 50,000 years ago. Except for a few genetic changes in skin color and other superficial qualities, humans everywhere are supposedly alike because there hasn’t been enough time for significant differences to evolve in their brains and innate behavior. This belief was plausible when biologists assumed that evolution was a slow process, but the decoding of the human genome has disproved it, as Nicholas Wade (a former colleague of mine at the New York Times) reported in his 2015 book, A Troublesome Inheritance. “Human evolution has been recent, copious and regional,” writes Wade, noting that at least 8 percent of the human genome has changed since the departure from Africa. The new analysis has revealed five distinguishable races that evolved in response to regional conditions: Africans, East Asians, Caucasians, the natives of the Americas, and the peoples of Australia and Papua New Guinea. Yet social scientists go on denying the very existence of races. The American Anthropological Association declares race to be “a human invention” that is “about culture, not biology.” The American Sociological Association calls race a “social construct.” Even biologists and geneticists are afraid of the R-word. More than 100 of them sent a letter to the New York Times denouncing Wade’s book as inaccurate, yet they refused to provide any examples of his mistakes. They apparently hadn’t bothered to read the book because they accused Wade of linking racial variations to IQ scores—a link that his book specifically rejected. Some genetic differences are politically acceptable on the left, such as the biological basis for homosexuality, which was deemed plausible by 70 percent of sociologists in a recent survey. But that same survey found that only 43 percent accepted a biological explanation for male-female differences in spatial skills and communication. How could the rest of the sociologists deny the role of biology? It was no coincidence that these doubters espoused the most extreme left-wing political views and the strongest commitment to a feminist perspective. To dedicated leftists and feminists, it doesn’t matter how much evidence of sexual differences is produced by developmental psychologists, primatologists, neuroscientists, and other researchers. Any disparity between the sexes—or, at least, any disparity unfavorable to women—must be blamed on discrimination and other cultural factors."
