AI authorship disclosure at major newspapers
- Semafor found AI signals in 50 of 310 guest columns at newspapers with explicit anti-AI policies, and a Pew Research study found roughly one-third of web pages published since ChatGPT launched show signs of AI authorship, expanding debate that began when the Wall Street Journal published an op-ed by investor Stanley Druckenmiller on August 25 that readers considered entirely AI-generated.
- Pew also recorded em dash usage roughly doubling and Oxford comma usage rising 63% across the web since 2023.
A major publication's explicit defense of AI-written contributor content without mandatory disclosure sets a concrete editorial precedent. The Pew Research data shows AI writing is already pervasive across the commercial web, making consistent policy enforcement difficult.
