Overview
- Julie Bedard told the Hard Fork podcast she is quite pessimistic that workers will quickly overcome AI-induced cognitive fatigue.
- The Harvard Business Review study she coauthored found 14% of 1,488 full-time U.S. workers reported symptoms such as mental fog, headaches, and slower decision-making.
- Researchers say the effect is driven by the high cognitive load of reviewing and validating AI outputs rather than traditional burnout.
- Productivity rose when workers used one to two AI tools but gains shrank with a third tool and then declined as people juggled more systems.
- Incidence was higher in marketing, HR, operations, and software engineering than in legal and compliance, and the authors urge companies to seek employee feedback on AI integration.
