AI is causing cognitive fatigue. Here’s how to work with more haste and less speed

Quick take

AI tools are making knowledge workers push harder, not smarter, leading to cognitive fatigue. Research finds people are working faster but less efficiently, overwhelmed by constant input and pressure to produce. Instead of enabling better decisions or deeper thinking, some AI workflows increase mental strain and slow true progress.

Why it matters

Cognitive fatigue lowers quality and creativity, so relying on AI without changing how tasks get done backfires. For builders, founders, and operators, the problem is how to integrate AI as a smart assistant rather than a busywork driver. It means designing workflows that balance speed with thoughtful pauses, not just pushing for nonstop output.

Companies and users need to shift from speed-focused use toward smarter collaboration with AI. Training and systems should reward quality over quantity and manage attention better. Done right, AI can reduce mental exhaustion instead of adding to it—freeing people to do higher-value work without burning out.

That changes how teams work day-to-day, project planning, and product roadmaps. Anyone adopting AI tools faces pressure to redesign workflows or risk declining performance and employee fatigue. The payoff is AI as a tool to work with more haste and less reckless speed.
