The Balancing Item: The AI Oversight Cost Your Business Case Never Priced

Every AI business case counts the hours saved. Almost none counts the hours added: the reviewing, correcting, and supervising that AI outputs demand before anyone can rely on them. That oversight labour is real, regulation increasingly mandates it, and people absorb it silently on top of existing roles. BCG research published in March 2026 shows the consequence: a distinct mental fatigue attaching to heavy AI oversight loads, while workers using AI only to replace routine work report less burnout, not more. I argue this fatigue is a control cost Boards must price, and the remedy is governance, not resilience training.
