John Tooby, the founder of MacDonald's field of evolutionary psychology, criticized MacDonald in an article for Salon.com in 2000. He wrote, "MacDonald's ideas — not just on Jews — violate fundamental principles of the field." Tooby said MacDonald is not an evolutionary psychologist, and advocates models incorporating group-selection theory, a view of natural selection whose importance is disputed.[21]
MacDonald has also been accused of employing scapegoating techniques that resemble classical Nazism.[22] Steven Pinker, while acknowledging that he had "not plowed through MacDonald's trilogy and therefore run the complementary risks of being unfair to his arguments, and of not refuting them resoundingly enough to distance them from my own views on evolutionary psychology", states that MacDonald's theses are unable to pass the threshold of attention-worthiness or peer-approval, and contain a "consistently invidious portrayal of Jews, couched in value-laden, disparaging language."[23] Reviewing MacDonaldÂ’s A People That Shall Dwell Alone, Sander Gilman describes MacDonald's argument about a Jewish group evolutionary strategy as a "bizarre" one which "recasts all of the hoary old myths about Jewish psychological difference and its presumed link to Jewish superior intelligence in contemporary sociobiological garb."[24] Eugen Schoenfeld states the book contains "sloppy scholarship" and that MacDonald's comparison of Jewish collectivism during the biblical period with eighteenth- and nineteenth-century English individualism "indicates a total ignorance of the impact of industrialization on Western societies."[25]
John Hartung, an anesthetist and theorist of human behavioral ecology, at first interested in his work, said MacDonald's The Culture of Critique was "quite disturbing, seriously misinformed about evolutionary genetics, and suffering from a huge blind spot about the nature of Christianity."[26]
MacDonald has particularly been accused by other academics of academic fraud, saying that he has promoted anti-Semitic propaganda under the guise of what he says is a legitimate and academic search for truth.[27] He has also been accused of misrepresenting the sources he uses in that regard. Fenris State University professor Dr. Barry Mehler cited for example a quote from a 1969 dissertation by Sheldon Morris Neuringer titled American Jewry and United States immigration policy, 1881-1953 where MacDonald surmised that when Neuringer noted Jewish opposition in 1921 and 1924 to the anti-immigration legislation at the time was due more to it having the “taint of discrimination and anti-Semitism” as opposed to how it would limit Jewish immigration, MacDonald wrote, “…Jewish opposition to the 1921 and 1924 legislation was motivated less by a desire for higher levels of Jewish immigration than by opposition to the implicit theory that America should be dominated by individuals with northern and western European ancestry.” “It seems to me Mr. MacDonald is misrepresenting Mr. Neuringer in this case and I posted my query hoping that a historian familiar with the literature might have a judgment on MacDonald's use of the historical data,” Mehler wrote, citing other examples.[28]
Reviewing MacDonald's Separation and Its Discontents in 2000, Zev Garber writes that MacDonald works from the assumption that the dual Torah is the blueprint of the eventual Jewish dominion over the world, and that he sees contemporary antisemitism, the Holocaust, and attacks against Israel as "provoked by Jews themselves." Garber concludes that MacDonald's "rambling who-is-who-isn't roundup of Jews responsible for the 'Jewish Problem' borders on the irrational and is conducive to misrepresentation."[29]
In 2001, David Lieberman, a Holocaust researcher at Brandeis University, wrote a paper entitled Scholarship as an Exercise in Rhetorical Strategy: A Case Study of Kevin MacDonald's Research Techniques, where he noted how one of MacDonald’s sources, author Jaff Schatz, objected to how MacDonald used his writings to further his premise that Jewish self-identity validates anti-Semitic sentiments and actions. “At issue, however, is not the quality of Schatz's research, but MacDonald's use of it, a discussion that relies less on topical expertise than on a willingness to conduct close comparative readings," Lieberman wrote.[30]
Lieberman has also written that MacDonald even dishonestly made up lines from the work of British Holocaust denier David Irving. Citing Irving's Uprising which was published in 1981 for the twenty-fifth anniversary of Hungary's failed anti-Communist revolution in 1956, MacDonald asserted in the Culture of Critique, "The domination of the Hungarian communist Jewish bureaucracy thus appears to have had overtones of sexual and reproductive domination of gentiles in which Jewish males were able to have disproportionate sexual access to gentile females." Lieberman, who also noted that MacDonald is not a historian, debunked those assertions, concluding, "(T)he passage offers not a shred of evidence that, as MacDonald would have it, "Jewish males enjoyed disproportionate sexual access to gentile females."[31
