In a preregistered online experiment, occupation-specific, incentivized writing tasks were assigned to 453 college-educated professionals and randomly exposed half of them to ChatGPT.
The results show that ChatGPT substantially raised productivity: The average time taken decreased by 40% and output quality rose by 18%.
Inequality between workers decreased, and concern and excitement about AI temporarily rose. Workers exposed to ChatGPT during the experiment were 2 times as likely to report using it in their real job 2 weeks after the experiment and 1.6 times as likely 2 months after the experiment.
