Since the second half of the 20th century, scientific racism has been discredited and criticized as obsolete, yet has persistently been used to support or validate racist world-views based upon belief in the existence and significance of racial categories and a hierarchy of superior and inferior races.
[12][13][14][15] The term scientific racism was popularized by Stephen Jay Gould who used it in his 1981 book The Mismeasure of Man to describe the historical role of science in propagating the ideal of White racial superiority.
[17] Publications such as the Mankind Quarterly, founded explicitly as a "race-conscious" journal, are generally regarded as platforms of scientific racism because they publish fringe interpretations of human evolution, intelligence, ethnography, language, mythology, archaeology, and race.
In his 1734 book Sketches on the History of Man, Home claimed that the environment, climate, or state of society could not account for racial differences, so the races must have come from distinct, separate stocks.
[26] Carl Linnaeus (1707–1778), the Swedish physician, botanist, and zoologist, modified the established taxonomic bases of binomial nomenclature for fauna and flora, and also made a classification of humans into different subgroups.
[41] Paleontologist Stephen Jay Gould (1994) argued that the taxa was "not in the ranked order favored by most Europeans in the racist tradition", and that Linnaeus' division was influenced by the medical theory of humors, which said that a person's temperament may be related to biological fluids.
"It was quite clear, after reading Buffon, that he uses the word in no narrowly defined, but rather in a general sense",[46] wrote Montagu, pointing out that Buffon did employ the French word la race, but as a collective term for whatever population he happened to be discussing at the time; for instance: "The Danish, Swedish, and Muscovite Laplanders, the inhabitants of Nova-Zembla, the Borandians, the Samoiedes, the Ostiacks of the old continent, the Greenlanders, and the savages to the north of the Esquimaux Indians, of the new continent, appear to be of one common race".
[49] According to this model, Negroid pigmentation arose because of the heat of the tropical sun; that cold wind caused the tawny colour of the Eskimos; and that the Chinese had fairer skins than the Tartars, because the former kept mostly in towns, and were protected from environmental factors.
According to an article published in the McGill Journal of Medicine: "One of the most influential pre-Darwinian racial theorists, Jefferson's call for science to determine the obvious 'inferiority' of African Americans is an extremely important stage in the evolution of scientific racism".
Cuvier wrote about Caucasians: "The white race, with oval face, straight hair and nose, to which the civilised people of Europe belong, and which appear to us the most beautiful of all, is also superior to others by its genius, courage, and activity".
The projection of the lower parts of the face, and the thick lips, evidently approximate it to the monkey tribe: the hordes of which it consists have always remained in the most complete state of barbarism.He thought Adam and Eve were Caucasian, and hence, the original race of mankind.
He believed that the white race was superior, writing: I will not wait for the friends of equality to show me such and such passages in books written by missionaries or sea captains, who declare some Wolof is a fine carpenter, some Hottentot a good servant, that a Kaffir dances and plays the violin, that some Bambara knows arithmetic... Let us leave aside these puerilities and compare together not men, but groups.
[68][73] The historian Richard Hofstadter wrote: Although Darwinism was not the primary source of the belligerent ideology and dogmatic racism of the late nineteenth century, it did become a new instrument in the hands of the theorists of race and struggle...
Although by modern standards The Descent of Man is frustratingly inconclusive on the critical issues of human equality, it was a model of moderation and scientific caution in the context of midcentury racism".
[78][79] Like most of Darwin's supporters,[citation needed] Ernst Haeckel (1834–1919) put forward a doctrine of evolutionary polygenism based on the ideas of the linguist and polygenist August Schleicher, in which several different language groups had arisen separately from speechless prehuman Urmenschen (German for 'original humans'), which themselves had evolved from simian ancestors.
[71] At the 19th century's end, scientific racism conflated Greco-Roman eugenicism with Francis Galton's concept of voluntary eugenics to produce a form of coercive, anti-immigrant government programs influenced by other socio-political discourses and events.
The most influential theorists included the anthropologist Georges Vacher de Lapouge (1854–1936) who proposed "anthroposociology"; and Johann Gottfried Herder (1744–1803), who applied "race" to nationalist theory, thereby developing the first conception of ethnic nationalism.
In the 19th century, an early American physical anthropologist, physician and polygenist Samuel George Morton (1799–1851), collected human skulls from worldwide, and attempted a logical classification scheme.
[83] In The Mismeasure of Man (1981), the evolutionary biologist and historian of science Stephen Jay Gould argued that Samuel Morton had falsified the craniometric data, perhaps inadvertently over-packing some skulls, to so produce results that would legitimize the racist presumptions he was attempting to prove.
Palacios argued on medical grounds against immigration to Chile from southern Europe claiming that Mestizos who are of south European stock lack "cerebral control" and are a social burden.
[citation needed] The book The Passing of the Great Race (Or, The Racial Basis of European History) by American eugenicist, lawyer, and amateur anthropologist Madison Grant was published in 1916.
[95] In 1851, in antebellum Louisiana, the physician Samuel A. Cartwright (1793–1863) wrote of slave escape attempts as "drapetomania", a treatable mental illness, that "with proper medical advice, strictly followed, this troublesome practice that many Negroes have of running away can be almost entirely prevented".
In Medical Apartheid, Harriet A. Washington noted the prevalence of two different views on blacks in the 19th century: the belief that they were inferior and "riddled with imperfections from head to toe", and the idea that they did not know true pain and suffering because of their primitive nervous systems (and that slavery was therefore justifiable).
Washington noted the failure of scientists to accept the inconsistency between these two viewpoints, writing that: in the eighteenth and nineteenth centuries, scientific racism was simply science, and it was promulgated by the very best minds at the most prestigious institutions of the nation.
Nathaniel Shaler, a prominent geologist at Harvard University from 1869 to 1906, published the book Man and the Earth in 1905 describing the physical geography of different continents and linking these geologic settings to the intelligence and strength of human races that inhabited these spaces.
Before World War II (1939–45), scientific racism remained common to anthropology, and was used as justification for eugenics programs, compulsory sterilization, anti-miscegenation laws, and immigration restrictions in Europe and the United States.
[130]: 16 In the 20th century, concepts of scientific racism, which sought to prove the physical and mental inadequacy of groups deemed "inferior", was relied upon to justify involuntary sterilization programs.
In the late 19th century, the Plessy v. Ferguson (1896) United States Supreme Court decision—which upheld the constitutional legality of racial segregation under the doctrine of "separate but equal"—was intellectually rooted in the racism of the era, as was the popular support for the decision.
By 1954, 58 years after the Plessy v. Ferguson upholding of racial segregation in the United States, American popular and scholarly opinions of scientific racism and its sociologic practice had evolved.
Kevin MacDonald, in his Culture of Critique series, used arguments from evolutionary psychology to promote antisemitic theories that Jews as a group have biologically evolved to be highly ethnocentric and hostile to the interests of white people.
