Kevin MacDonald (evolutionary psychologist)

Kevin B. MacDonald (born January 24, 1944) is an American antisemitic conspiracy theorist, white supremacist, and retired professor of evolutionary psychology at California State University, Long Beach (CSULB). In 2008, the CSULB academic senate voted to disassociate itself from MacDonald's work.

MacDonald is known for his promotion of an antisemitic theory, most prominently within The Culture of Critique series, according to which Western Jews have tended to be politically liberal and involved in politically or sexually transgressive social, philosophical, and artistic movements, because Jews have biologically evolved to undermine the societies in which they live. In short, MacDonald argues that Jews have evolved to be highly ethnocentric, and hostile to the interests of white people. In an interview with Tablet magazine in 2020, MacDonald said: "Jews are just gonna destroy white power completely, and destroy America as a white country."

Scholars characterize MacDonald's theory as a tendentious form of circular reasoning, which assumes its conclusion to be true regardless of empirical evidence. The theory fails the basic test of any scientific theory, the criterion of falsifiability, because MacDonald refuses to provide or acknowledge any factual pattern of Jewish behavior that would tend to disprove his idea that Jews have evolved to be ethnocentric and anti-white. Other scholars in his field dismiss the theory as pseudoscience analogous to older conspiracy theories about a Jewish plot to undermine European civilization.

MacDonald's theories have received support from antisemitic conspiracy theorists and neo-Nazi groups. He serves as editor of The Occidental Observer, which he says covers "white identity, white interests, and the culture of the West". He is described by the Anti-Defamation League as having "become a primary voice for anti-Semitism from far-right intellectuals" and by the Southern Poverty Law Center as "the neo-Nazi movement's favorite academic". He has been described as part of the alt-right movement. By 2010, MacDonald was one of the eight members of the board of directors of the newly founded American Third Position (known from 2013 as the American Freedom Party), an organization stating that it "exists to represent the political interests of White Americans".
