Impact of ChatGPT on the writing style of condensed matter physicists
This addresses the problem of language barriers in scientific writing for non-native English-speaking physicists, showing incremental adoption effects.
The study estimated the impact of ChatGPT's release on the writing style of condensed matter physics papers, finding a statistically significant improvement in English quality for non-native speakers and changes in word usage patterns.
We apply a state-of-the-art difference-in-differences approach to estimate the impact of ChatGPT's release on the writing style of condensed matter papers on arXiv. Our analysis reveals a statistically significant improvement in the English quality of abstracts written by non-native English speakers. Importantly, this improvement remains robust even after accounting for other potential factors, confirming that it can be attributed to the release of ChatGPT. This indicates widespread adoption of the tool. Following the release of ChatGPT, there is a significant increase in the use of unique words, while the frequency of rare words decreases. Across language families, the changes in writing style are significant for authors from the Latin and Ural-Altaic groups, but not for those from the Germanic or other Indo-European groups.
