Not sure the earliest but while it was common sense throughout history given the domestication of animals, and common sense in science from about 1905, and presumed science by the majority prior to the second world war. It was only the revolt against the Nazi use of American Eugenic Research in the thirties that produced the vast wealth of postwar pseudoscience, and the switch from (anglo) Darwin and Spencer as the foundation of social science to the pseudoscientists we know and popularize as (jewish) Boaz, Freud, Marx et al – each of whom is little more than a revolt against darwin, spencer and nietzche (who were correct of course).
