Seems like the honest comparison of the rates of attrition would be between Christian scholars trying to prove the historicity of the Bible versus Mormon scholars trying to prove the historicity of the Book of Mormon.
Have any references on that? Care to weigh in with your personal opinion?
I don’t think there is any doubt attempting to prove the historicity of the BOM is much tougher than doing the same with the Bible.
The Bible is conceded even by its critics to be an ancient book written by men who lived during or not long after the events they relate.
The BOM is taken by all but devout Mormons to be a work of fiction written by a not particularly well-educated young American man in the early 19th century. As a work of fiction it is quite remarkable. As a work of history it is ludicrous.
I once tried to read the BOM. Could not believe how boring it was, compared to the Bible, which admittedly also has unbelievably boring sections. Even as a literary work it is much inferior.
