BCG Says ‘AI Brain Fry’ Hits 14% of Workers — 4+ Tools Tanks Productivity

Honestly, the machines were supposed to do the work. Instead you’re babysitting 6 chatbots and your dopamine is shot by lunch.

A new BCG study of 1,488 US workers found that using 4+ AI tools simultaneously causes self-reported productivity to plummet — while mental fatigue jumps 12%, information overload spikes 19%, and 34% of affected workers are actively planning to quit.

Published in Harvard Business Review, the study coined a term for the phenomenon: “AI brain fry.” It’s not burnout (that slow emotional decay you’ve known for years). It’s acute cognitive overload — fog, headaches, bad decisions, and the inability to answer “how was your day” after 15 hours of prompt-wrangling.
