EY has retracted a 2025 study on loyalty rewards programs after researchers found numerous AI-generated inaccuracies, including fake citations and misattributed data. The report, which claimed the loyalty program economy was worth $200 billion and cited non-existent sources, was used by EY consultants in Canada to promote their cybersecurity services. Investigators from GPTZero revealed that approximately 60% of the references in the report were fabricated, raising concerns about the reliability of AI-generated content in professional reports. The withdrawal highlights the potential risks associated with AI hallucinations in critical business documents. EY has not publicly commented on the retraction.

Key Points: • EY's report on loyalty programs was retracted due to AI-generated inaccuracies. • Researchers found 60% of the report's references were fabricated or misattributed. • The incident underscores the risks of relying on AI for generating professional content.
