New term for AI-related fatigue

A newly identified type of mental exhaustion, called "brain fry," is being experienced by people who supervise multiple AI agents at once. This condition is primarily affecting developers and other professionals who work closely with artificial intelligence tools.

Work continues beyond office hours

Coralie Delpha, a lead forward deployed engineer at Railblocks, often leaves her office with her computer still on. Multiple AI agents continue working on tasks she assigned, even after she has left for the day. This shift in work dynamics has led to new challenges for workers like her.

Study identifies "brain fry" phenomenon

Researchers from Boston Consulting Group and the University of California at Riverside identified "brain fry" in a study published in the Harvard Business Review in March 2026. The study, based on employee interviews, suggests that managing multiple AI tools can lead to significant mental fatigue.

Survey highlights impact on workers

The study surveyed 1,488 full-time American employees. Among those who use AI, 14% reported experiencing "brain fry." Those managing multiple AI agents simultaneously reported higher levels of fatigue and were more likely to consider leaving their jobs.

Long-term study confirms findings

At the Haas School of Business at the University of Berkeley, Aruna Ranganathan and Xingqi Maggie Ye conducted an eight-month study of an American tech company with about 200 employees. Their findings, also published in the Harvard Business Review, support the concept of "brain fry" and its impact on workplace dynamics.
