The Southern Poverty Law Center has documented Harpending's works and statements on race, noting his association with white supremacist groups and referring to his work as an attempt to perpetuate scientific racism. The SPLC notes he attributed stereotypes of different human populations to genetic differences, often saying that Africans, Papua New Guineans, and "Baltimore" (African-Americans) possess the same genetic temperamental predispositions which he said are characterized by "violence, laziness, and a preference for 'mating instead of parenting'", while Europeans and northern Asians "have evolved higher intelligence and 'tend to be more disciplined than people who take life for granted'"; that he favored mass deportation of illegal immigrants from the United States using FEMA camps as part of the process and did not believe that more money should be spent on education in the United States because he thought the race-based disparities are based on genetics rather than disparities in funding; that he gave conferences at what the SPLC designates as white supremacist groups; and that he supported eugenics, crediting it in the form of the death penalty for the "genetic pacification" of the western European population.
