Jason Arday, a sociology professor at the University of Cambridge, resigned on Wednesday, August 7th, 2026, after the university announced an investigation into his academic qualifications and honorary appointments amid multiple plagiarism accusations.

The allegations first surfaced last month when former Cambridge philosophy researcher Nathan Cofnas published a Substack article accusing Arday of being a "known plagiarist and fabulist" for over a year. Cofnas also expressed skepticism about Arday's personal biography, noting inconsistencies such as Arday reportedly being nonverbal until age eleven and nearly illiterate until 18, yet still obtaining a Ph.D. in 2015 and becoming the youngest Black professor at Cambridge in 2023.

Using the plagiarism-detection software Copyleaks, Cofnas identified several instances where Arday allegedly lifted material directly from a 2009 dissertation without proper citation, sometimes even retaining copy-editing errors. Cofnas told Fox News Digital that Arday was hired by Cambridge to be the "face of DEI" (Diversity, Equity, and Inclusion) and was "doing a great job."

The University of Cambridge confirmed it had begun an investigation following new information about Arday's academic credentials and honorary titles but declined further comment until the process concludes.

Shortly after the university's announcement, Arday issued a statement through the Good Law Project declaring his immediate resignation, citing "public scrutiny" as a factor.

Critics have also questioned the scholarly rigor of Arday's work, with some noting a lack of familiarity with elementary statistics and describing his research as largely subjective commentary based on personal experiences and conversations.
