Ziff, Ray, and Kent Larsen had it right — the Book of Mormon has the largest standard deviation in ratings of any book on the site. The stat is called “25 Books People Can’t Agree On” and you can see it at the bottom of this page.
The Book of Mormon may be at the top of the list, but it’s in good company, since books by Nathaniel Hawthorne and Isaac Newton are also on the list. (Of course, the urban vampire fantasy and regency romance do drag down the neighborhood a bit.)
It’s also the most widely-owned of any book on that list, by far. There are around 1,600 LibraryThing members who own a total of around 1,800 copies of the Book of Mormon. The next most widely held book is Hawthorne’s The Marble Faun, at around 400 copies. There have been some other popular books on the list, but they tend to drop off when they get very popular, because enough people give them an intermediate rating (2.5-3.5 stars) that it lowers the standard deviation of all the ratings. The Secret, a book made popular by Oprah Winfrey, used to be on the list, but now the standard deviation of the ratings is down to 1.34, well below the current top-25 cutoff of 1.42. Read More
