What happened
A study published in Harvard Business Review of 1,500 workers found constant juggling of multiple AI tools increases decision fatigue and errors, leading to "AI brain fry." One in seven workers reported mental fatigue from this oversight. Conversely, using AI to offload repetitive tasks reduced worker stress. Julie Bedard, a Boston Consulting Group managing director and study author, noted intensive AI oversight causes cognitive exhaustion, challenging expectations around AI productivity.
Why it matters
Organisations face increased worker errors and slower decision-making when employees constantly supervise multiple AI systems. This cognitive overload, experienced by one in seven workers, stems from the expanded workload and accountability AI enables. Procurement teams and platform architects must prioritise intentional AI integration, redesigning workflows rather than simply layering AI onto existing processes, to prevent "brain fry" and maintain productivity.
