AI ID's Anonymous Writing

An advanced AI model correctly identified a writer as the author of a 1,000-word scene from an unpublished novel. I tried Claude on the first chapter of a romance novel that I started almost 20 years ago. (It identified me after only) a few seconds.  I fed Claude a different opening chapter from an unpublished science fiction novel I started right before the pandemic. Claude needed only 1,132 words to identify the author. -Megan McArdle writing in The Washington Post
