- University of Southern California study found writing style diversity dropped sharply after ChatGPT's release, analyzing scientific journals, local news articles and social media.
- Max Planck Institute for Human Development researchers observed increased usage of ChatGPT-favored words such as "delve," "meticulous," "boast," and "comprehend" in everyday conversation after reviewing 740,249 hours of content.
- Morteza Dehghani (USC professor) said people adopt the idealized, predictable language of LLMs even when not using them, to appear powerful and influential.
- Alex Mahadevan, chief AI instructor at the Poynter Institute, described AI-generated writing as "soulless" and "mediocre," despite being grammatically correct.
- Emily Bender, linguist at the University of Washington, noted she tries to avoid reading synthetic text but often cannot tell if something was generated by AI.
- Brookings 2025 survey reported 32% of small businesses use AI for customer service/outreach and 16% of individuals use LLMs for communication or social media.
Why it matters: The shift toward AI‑styled prose erodes authentic voices, meaning writers and readers lose the richness of diverse expression while businesses and individuals seeking polished communication gain a uniform, but bland, linguistic template that may diminish creativity and critical thinking in society.
