HBR Study: 14% of Workers Experience AI-Induced Mental Fog, High Performers Hit Hardest
A Harvard Business Review survey of 1,500 full-time workers found that 14% already experience "AI-induced mental fog." High AI oversight correlates with a 12% increase in mental fatigue and a 33% jump in decision fatigue. Technical workers—software developers, IT, and finance professionals—are most affected. High performers show the strongest negative effects. Exhausted employees are 10% more likely to quit. At large firms, the study estimates AI-related decision paralysis leads to millions in lost value annually.
Why It Matters
The same week MIT's EEG study documented reduced neural connectivity from AI writing use, HBR's workplace survey quantifies productivity and retention costs from cognitive overload. Two independently sourced empirical datasets on AI cognitive cost arrived in the same news cycle.
