Experimental evidence on the productivity effects of generative artificial intelligence
Research summary
In a preregistered experiment with 453 professionals, ChatGPT access reduced task time by 40% and increased assessed output quality by 18%. Lower-skill participants benefited most on the short writing tasks studied.
Evidence strengths
- Random assignment
- Preregistered experiment
- Incentivized occupation-specific tasks
Limitations
- Short and self-contained tasks
- College-educated sample
- Primarily immediate outcomes
Topics
- Human-AI Interaction
- Artificial Intelligence
- Learning
Connected claims
- Supports
Human-AI collaboration does not reliably outperform the better standalone human or AI; results depend strongly on the task and interaction design.
Randomized access to ChatGPT improved speed and quality on bounded professional writing tasks, especially for lower-skill participants.
