Cambridge has opened a formal probe into a star professor after reports counted more than 100, and then 188, overlapping sentences in his PhD — and the opaque way universities handled earlier reviews is now the bigger trust test than the text itself.
Story Highlights
- Cambridge launched an investigation into Professor Jason Arday after “new information.”
- Media analyses reported large overlap between Arday’s 2015 thesis and a 2009 thesis.
- Liverpool John Moores University previously reviewed the thesis and did not uphold plagiarism.
- Confidential processes and legal threats cloud public confidence in how elites police themselves.
What Triggered Cambridge’s New Investigation
On August 5, the University of Cambridge said it will investigate Professor Jason Arday after receiving “new information” about his qualifications and record. The decision followed weeks of coverage that pushed detailed plagiarism claims into the spotlight. Reports described overlap in his 2015 PhD thesis with a 2009 dissertation by Paula Zwozdiak-Myers. The Guardian reported more than 100 similar passages, and later coverage cited 188 similar sentences in a fresh review.
Allegations did not start inside Cambridge. A critic outside the university first posted comparisons and raised questions. Major outlets then examined the claims and gathered documents. The pattern fits many academic scandals: an outside dossier pushes officials to act only after public pressure builds. That delay fuels the feeling that elite places move only when headlines leave them no choice, not when rules say they should.
What Earlier Reviews Found — And Why That Fuels Doubt
Before Cambridge’s move, Liverpool John Moores University reportedly reviewed the thesis and did not uphold plagiarism. Reporting says the process was confidential and suggested any overlap could be “honest and reasonable error.” Cambridge also said relevant journals and Liverpool John Moores had examined prior complaints. Those statements matter. But they leave key questions because the schools did not publish side-by-side pages or their full reasoning.
The lack of public evidence is now the center of the trust problem. People on both the left and right see a closed system that shields insiders. Retraction Watch reported that a planned Times Higher Education story was dropped after lawyers at Carter-Ruck got involved. That detail suggests legal pressure can shape what the public learns. Without transparent files, many will assume the process protects status, not the truth.
The Competing Claims, Boiled Down
One side points to counted overlaps, specific passages, and a rising total from “over 100” to “188” sentences. That feels concrete to readers. The other side points to institutional reviews that did not find plagiarism and Arday’s denials. That feels official but vague without the underlying pages. In simple terms, one camp shows text; the other cites process. The stronger answer would be a public, line-by-line rebuttal or a neutral forensic comparison.
Jason Arday, the Cambridge professor who resigned following allegations of plagiarism and unsubstantiated claims, is originally Ghanaian 😳😳😳

Cambridge’s new inquiry is a chance to reset the standard. A credible review can do three things. It can publish clear criteria. It can present a documented side-by-side of every flagged passage with context. And it can explain intent, citation practice, and any honest-error findings in plain words. Anything less will deepen the view that rules change for the powerful, and that identity and politics replace proof. That view is already spreading far beyond one thesis.
