PwC has become the latest member of the Big Four consulting firms to face criticism over its use of artificial intelligence (AI), after several of its published reports were found to contain fabricated citations, incorrect references and other factual errors.
The latest findings have further intensified the concerns over how professional services firms are using generative AI to produce research, while advising clients on responsible AI adoption.
The episode follows similar incidents involving KPMG, EY and Deloitte, placing the industry’s AI practices under renewed scrutiny.
Investigation Uncovers Fabricated References
The issue came to light after AI detection company GPTZero reviewed a series of PwC Middle East “thought leadership” reports covering topics including artificial intelligence, electric vehicles and public services.
The investigation further found multiple fabricated footnotes, links to non-existent academic research papers, misattributed claims & references that could not be verified.
In one case, a citation even listed ChatGPT as the source URL, highlighting clear failures in editorial checks.
Researchers also came across instances where different references across reports backed identical claims. At the same time, some sources either did not exist or had no connection to the statements they were cited to support. The findings suggest heavy reliance on generative AI without sufficient human verification before publication.

PwC Joins Growing List of Big Four AI Setbacks
PwC said it takes the matter seriously and is correcting inaccurate citations, although it did not explain how the errors entered the published reports.
The development comes weeks after KPMG withdrew an AI report following concerns over fabricated citations and disputed case studies. Earlier, EY also retracted research after AI-generated errors were identified. Deloitte has likewise faced questions over AI-generated content, making PwC the latest Big Four firm to confront challenges linked to unchecked AI outputs.

Why the Incident Matters?
The controversy extends beyond publishing mistakes.
The Big Four have collectively promoted AI adoption while positioning themselves as trusted advisers on AI governance, risk management & responsible deployment.
The latest incidents underline the risks of relying on generative AI without rigorous human review, especially in reports designed to influence business decisions and attract consulting clients.
As enterprises accelerate AI adoption, the focus is shifting from how quickly AI can produce content to how reliably organisations can verify it. For consulting firms, strong human oversight is becoming just as important as the technology itself.
