Professional writing with ChatGPT
Randomised online experiment · 453 college-educated professionals · occupation-specific writing tasks
- 40%less time on the assigned writing tasks
- 18%higher independently rated output quality
The largest quality gains went to participants whose first, unassisted task received lower scores. That suggests AI can help with a first draft or structure, not that it replaces domain knowledge.
Important limit: The 20–30-minute tasks did not require company-specific context, and the researchers did not test factual accuracy. Do not apply these percentages to every workplace document.
