According to the study, published by Harvard Business Review, 14% of workers who use AI on the job reported experiencing this kind of strain, often describing it as a “buzzing” feeling, mental fog, or a “mental hangover” that slows decision-making and makes it harder to focus.
Marketing employees reported the highest rates of AI brain fry, at 25.9%. Human resources and people operations staff followed closely, at 19.3%. Other industry roles experiencing brain fry include:
Operations (17.9%)
Engineering or software development (17.8%)
Finance or accounting (16.7%)
Information technology (16.0%)
Sales or business development (12.5%)
Customer service or support (10.6%)
Service provider or consultant (10.3%)
Product management (8.6%)
Management or leadership (8.6%)
Legal or compliance (5.6%)
Suffering from ‘AI Brain Fry’
The study found that the single most mentally taxing pattern of AI use was intensive oversight – the degree to which tools had to be constantly monitored, checked, or corrected by humans.
A senior engineering manager quoted in the article said the proliferation of tools left their mind feeling crowded.
“I had one tool helping me weigh technical decisions, another spitting out drafts and summaries, and I kept bouncing between them, double-checking every little thing,” the manager said.
