I remember when some university used some software to discover that Joe Klein wrote a book about the Clintons but I don’t remember which book it was. I bet they could easily figure out who wrote Obama’s books.
That was “Primary Colors.”
Pretty much every university uses that software now to detect plagiarism and cheating.
Think you have to have several writing samples for it to work properly though, which is why most English classes now have a short ungraded “essay” on day one to establish a benchmark.
Not sure if it can tell who wrote it if the author didn’t, but definitely can tell through several samples if the author didn’t write it.
Course just like Barry’s birth certificate nobody has bothered checking because they just assume The Messiah is above board.
If you think that’s bad you ought to read some of Jimmy Carter’s poetry.
