Jason Arday, a sociology professor at the University of Cambridge, resigned on Wednesday, August 7, 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 and questioned much of his personal biography. Cofnas expressed skepticism about Arday's background, noting inconsistencies such as Arday reportedly being nonverbal until age eleven and nearly illiterate until 18, yet 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 stated it had begun an investigation following new information about Arday’s academic credentials and honorary appointments and declined further comment until the process concluded.

Shortly after the university's announcement, Arday released a statement through the Good Law Project declaring his immediate resignation, citing "public scrutiny" as a factor. Photographs from Getty Images and SOPA Images documented the announcement.

Critics have noted that beyond the plagiarized work, there appears to be little resembling genuine scholarship in Arday's research, which reportedly lacks familiarity with elementary statistics and relies heavily on subjective commentary based on personal experiences and conversations.
