John Philippe Rushton (December 3, 1943 – October 2, 2012) was a Canadian psychologist and author. He taught at the University of Western Ontario and became known to the general public during the 1980s and 1990s for research on race and intelligence, race and crime, and other apparent racial variations. His book Race, Evolution, and Behavior (1995) is about the application of r/K selection theory to humans.
Rushton's work was heavily criticized by the scientific community for the questionable quality of its research, with many alleging that it was conducted under a racist agenda. From 2002 until his death, he served as the head of the Pioneer Fund, an organization founded in 1937 to promote Eugenics, which worked actively with the Nazi party to promote theories of racial superiority and inferiority, and has been described as racist and white supremacist in nature and designated as a hate group by the Southern Poverty Law Center.
Rushton was a Fellow of the Canadian Psychological Association and a onetime Fellow of the John Simon Guggenheim Memorial Foundation.
