Nathan Cofnas

Early career

Cofnas wrote a book titled Reptiles with a Conscience: The Coevolution of Religious and Moral Doctrine, published in 2012 by Richard Lynn's Ulster Institute for Social Research, a British race and intelligence think tank. Cofnas later withdrew the book from publication, hoping to publish it in future work.^[3] In 2016, he attended the controversial London Conference on Intelligence.^[5]

In 2018, Cofnas argued in Human Nature that Kevin MacDonald's work promoting antisemitic tropes relied upon "misrepresented sources and cherry-picked facts" and that the "evidence actually favors a simpler explanation of Jewish overrepresentation in intellectual movements involving Jewish high intelligence and geographic distribution."^[6][3]

In 2019, Cofnas published a journal article in Philosophical Psychology arguing for the study of race and intelligence.^[7] Nine academics published a joint letter in Philosophical Psychology stating that his paper was not up to academic publishing standards, and was faulty in its methodology, in part by ignoring major studies that disproved his position. They also stated his paper had "racist ideological undertones" and "can reasonably be read as pandering to proponents of scientific racism".^[8] Philosophical Psychology editor Cees van Leeuwen later resigned over the controversy.^[2] Mitchell Herschbach, editor-in-chief of the journal, later published an editor's note recognizing flaws with the peer-review process that allowed Cofnas' paper to be published assuring that the journal will "implement procedural improvements so that, going forward, the journal better handles papers on controversial topics having sensitive moral and socio-political implications."^[9]

In 2020 Cofnas published a review on the effects of a vegan diet on intelligence. He has argued it may have negative effects due to vitamin deficiencies.^[10]

Emmanuel College, Cambridge

After receiving a Leverhulme Early Career Fellowship grant 2022, Cofnas became an early-career research fellow in the faculty of philosophy at Cambridge, where he taught philosophy of biology.^[2][11] He also became a research associate at Emmanuel College.^[2]

Cofnas describes himself as a "race realist", a euphemism for a proponent of scientific racism.^[12][13] In a February 2024 blog post, Cofnas said that in a meritocratic system, black people "would disappear from almost all high-profile positions outside of sports and entertainment" and "Harvard faculty would be recruited from the best of the best students, which means the number of black professors would approach zero per cent".^[13][2] Shortly after, a petition called for his firing and prompted investigations by the institutions associated with him.^[2] 58 Emmanuel students filed formal complaints against him.^[14] The investigations were opposed by prominent academics including Steven Pinker and Peter Singer on the grounds of freedom of speech.^[15] The University of Cambridge took no action after finding his post did not amount to discrimination or harassment, but Cofnas resigned after the backlash.^[16] Emmanuel College dismissed him, finding that his blog post amounted to a "rejection of diversity, equity, and inclusion" and was inconsistent with the university's mission.^[1][14] Cofnas, with support from the Free Speech Union and £85,000 in donations, sued Emmanuel College in August 2024 over his dismissal; he lost the lawsuit on the basis that the post had caused reputational harm.^[17][14][11] As of August 2026^[update], he was appealing the decision.^[11]

Ghent University

Cofnas was hired as a postdoctoral researcher by Ghent University in 2026. In response, students protested while a petition objected to his views and calling for his firing.^[4][18] The university defended his appointment, saying his statements did not violate the law or their ethical code.^[13] In a statement, the university said: "We oppose this attack on academic freedom. While we are not endorsing any specific claims Cofnas has made, we believe that academics must be able to put forward controversial or provocative claims without fear of losing their employment."^[19]

Cofnas gave a talk on "wokeism" to the university's Catholic Flemish Student Union in April 2026. Afterward, a student threw a bottle of yogurt at his head; Cofnas said it gave him a concussion.^[11]

In July 2026, Cofnas publicly accused University of Cambridge sociology professor Jason Arday of plagiarism in his doctoral thesis. Arday had in 2023 become the youngest black professor in the University's history.^[20] In a Substack post, Cofnas wrote that he had run Arday's doctoral thesis through plagiarism detection software and found that "many passages are lifted with minimal editing, sometimes retaining copy-editing mistakes from the original source". He also cast doubt on some other claims Arday had made about his life.^[21] Cofnas told Retraction Watch he began scrutinizing Arday's work after he was contacted by a Cambridge faculty member who believed that the University had not responded adequately to previous plagiarism allegations against Arday.^[22] His accusations were followed by reports by The Telegraph and The Guardian, and the controversy became the subject of significant attention in British media and on Twitter.^[23] Cofnas later joked that the Arday incident is "what happened if you don’t give Cofnas a job. ... After the revolution, I'll be the head of the department of eugenics and race science at Harvard."^[24] Arday, who denied the accusations but admitted to errors in his work, later resigned as a result of the scandal, which he said had resulted in "an unrelenting level of public scrutiny and personal attack".^[25] Shortly after his resignation, Arday was found dead at his London home.^[26] On August 20, 2026, Cofnas was suspended from Ghent University as part of a preliminary disciplinary investigation, due to public statements he had made about Arday in the preceding days.^[27]
