How the Story of Jason Arday Cambridge Began
In 2023, Cambridge named Jason Arday Professor of Sociology of Education. As per CNN, he is 41 and the youngest Black professor in the university’s history. His backstory drew huge coverage. He said he was autistic and dyslexic, could not speak until he was 11, and could not read or write until he was 18. The praise was loud at first. Then people started to check.
The Plagiarism Claims Take Hold
The first spark came from Nathan Cofnas, a former Cambridge researcher and self-described “race realist” who lost his college role after backlash to his views. He ran Arday’s PhD thesis through plagiarism-detection software and said he found extensive copying. The Daily Telegraph then reported that more than 100 passages of Arday’s PhD looked similar to an earlier thesis.
A separate analysis by The Times flagged parts of his 2015 doctorate as “identical or near-identical” to another researcher’s paper. The investigative site Retraction Watch added that a planned Times Higher Education report had been shelved in 2025 after a legal letter from the firm Carter-Ruck. Arday earned that PhD at Liverpool John Moores University. The university had already looked into the claims and let the doctorate stand, saying any faults were likely “honest and reasonable errors”.

Questions Beyond the Thesis
The scrutiny soon spread past his academic work. Reporting by The Guardian raised doubts about several vivid claims. Arday had said a pig’s head was sent to his parents’ home. He also said a masked man threatened him with a knife at Cambridge.
The Metropolitan Police said no such investigation had taken place. Arday stood by his account, asking, “Why would I lie?” Other claims unravelled too. Glasgow and Ohio State both said he had never held visiting professorships with them. A book he long listed, Being Young, Black and Male, was never actually published. Birkbeck said it had no record of a master’s he claimed to have completed there.
The Charity and Running Records
Arday had said he raised “£5.5m for over 80 charities”. According to the BBC, he also claimed he ran 30 marathons in 35 days and 600 miles in six days, the last stretch on a broken leg. Under pressure, the numbers shifted. He later said the 600 miles took twelve days, with rest days built in. He told reporters the fundraising was done with a syndicate of about 100 people and that non-disclosure agreements stopped him naming them.
Cambridge Changes Its Position
At first, Cambridge backed him hard, calling the claims part of “a vile campaign to undermine his credibility”. That stance shifted fast. The university said it had begun an investigation “following new information about Professor Arday’s academic qualifications and honorary appointments”. Jesus College launched a parallel process of its own. Hours later, Arday quit.
In a statement shared by the Good Law Project, he wrote: “While criticism is an inevitable part of academic life, what I have experienced has gone far beyond scholarly disagreement.” He added that the outcome should not “be mistaken for an acceptance of the narratives that have surrounded me”. He promised, “I will return.”
The Memoir Still Went Ahead
Despite the storm, his publisher held firm. As CBS News reported during the fallout, the book stayed on schedule. Simon & Schuster confirmed it would publish Great and Unfortunate Things, co-written with Eve Claxton, in the US on 11 August and the UK on 27 August. The Tribune reports that Arday said he was paid “1.4 million” for the memoir in a pre-empt deal. The Atlantic later noted that the book’s account differed from his book proposal, which had described a teenage car crash, a coma, and testicular cancer.

A Row About More Than One Man
The case split opinion. Philosopher Kathleen Stock said elite universities were “desperate for good press”. Academic Kehinde Andrews pushed back, saying there is “no benefit for Black people in higher education”. The Good Law Project’s open letter, signed by more than 10,000 people, called the plagiarism claims “entirely false”. Yet critics such as Purdue’s David Sanders said there was “no question that there is extensive plagiarism”. There was fallout for the press too. Reporter Jack Grove was investigated by police after he emailed Arday questions. Met Commissioner Mark Rowley later admitted the force had “dropped the ball”.
