PwC Middle East Under Scrutiny Over Research Reports

PwC has become the latest member of the Big Four consulting firms to face questions over the use of generative AI in published research after an investigation reportedly uncovered fabricated citations, broken links and references to studies that could not be verified.

According to a report by the Financial Times, researchers at GPTZero reviewed four thought leadership reports published by PwC Middle East over the past two years and identified multiple instances that they described as AI-generated "hallucinations."

The reports covered topics including artificial intelligence strategy, public services and electric vehicle market forecasts in the Middle East.

What the Investigation Found

According to the investigation, researchers identified several issues in the reports, including:

• References to studies that could not be located.
• Broken or inactive source links.
• Citations that allegedly did not support the claims being made.
• Repeated claims attributed to different sources.
• References that appeared inconsistent with publicly available information.

One example cited in the report involved an air quality study in Riyadh that investigators said they could not find under the cited journal or listed authors.

Another report reportedly cited a Medium blog post by an individual creator as evidence for an artificial intelligence use case involving JPMorgan Chase, even though the initiative reportedly predated the launch of ChatGPT.

Researchers also noted that one cited URL reportedly included the tracking parameter "utm_source=chatgpt.com", which they suggested may indicate AI-assisted sourcing. The presence of such a parameter alone, however, does not by itself establish how the report was created.

PwC Responds

Responding to the findings, PwC Middle East told the Financial Times that it "takes the accuracy of our published research seriously."

The firm said it is updating a limited number of supporting citations in the reports identified by the investigation.

PwC has not publicly stated that the reports were generated by AI but acknowledged that corrections to certain citations are being made.

Other Big Four Firms Have Faced Similar Issues

PwC is the latest among the Big Four accounting and consulting firms to face scrutiny over AI-generated content.

KPMG

Earlier this year, KPMG withdrew its report titled "Redefining Excellence in the Age of Agentic AI" after organisations reportedly challenged several case studies and achievements included in the publication.

EY

EY also removed a report on customer loyalty programmes after researchers reported inaccurate citations and references to studies that could not be verified.

The firm later said it was reviewing how the report had been published.

Deloitte

Deloitte previously faced criticism after a healthcare report prepared for the Canadian government reportedly contained factual inaccuracies that were alleged to have originated from AI-generated content.

Growing Debate Around AI Governance

The incidents have renewed discussion around how organisations verify AI-assisted work before publication.

Industry experts say generative AI can significantly improve productivity, but emphasise that published research intended to guide businesses or governments requires:

• Independent fact-checking.
• Source verification.
• Editorial review.
• Human oversight before publication.

The recent controversies have highlighted the reputational risks organisations may face if AI-generated content is published without adequate verification.

Why This Matters

The Big Four firms are among the world's most influential advisers on technology, governance and artificial intelligence adoption. Reports published by these firms often shape business strategies, investment decisions and public policy. Allegations of fabricated citations and unverifiable references therefore raise broader questions about editorial standards, AI governance and the importance of human review in professional research. While AI continues to become a mainstream productivity tool, these incidents underscore that responsibility for accuracy ultimately remains with the organisations publishing the content.
