    "body_text": "Researchers analyzed prompts and responses from nearly 4,000 back-office employees across 15 functions at one large firm over eight months in 2025. Their measures placed Strategy, Digital Innovation and Project Management highest and found senior employees using generative AI more sophisticatedly, a pattern consistent with domain expertise complementing the tool. The study found neither improvement over time nor lasting gains following formal training. Because the evidence is proprietary, observational and drawn from one firm, it does not establish that training is useless or that seniority causes better outcomes; it shows that access and attendance alone did not shift the measured habits in this setting.",
