Employees experience burnout as AI intensifies work and increases cognitive load

An eight-month study of 200 employees by Aruna Ranganathan and Xingqi Maggie Ye found AI use led to longer hours and increased mental fatigue, with BCG research identifying a 'brain fry' effect.
Rather than reducing workload, AI tools often increase task volume and complexity, causing more errors and poorer outcomes. Employees struggle with constant task switching and insufficient recovery time, undermining productivity.
Experts recommend organizations systematize quiet, meeting-free periods and educate staff on effective AI use. Emphasizing outcome-based performance and self-care strategies may help reverse the negative impacts of intensified AI-driven work.

Cognitive Overload and the AI Productivity Paradox: Evidence from the 2025-2026 BCG Survey
Overview
Between 2025 and 2026, a new challenge called "AI brain fry" has emerged, where workers experience mental fatigue and cognitive overload from using four or more AI tools simultaneously. This overload is driven by the constant need to oversee, prompt, and correct multiple AI systems, combined with frequent task switching and workload expansion fueled by AI's ability to speed up task initiation. These demands often exceed human cognitive limits, worsened by insufficient training and psychological pressures. High cognitive strain is especially notable in tech and HR sectors. Over time, heavy reliance on AI may cause "cognitive debt," weakening critical thinking and deep memory. Addressing this requires redesigning workflows and better support to balance AI benefits with human well-being.
