Why is it desirable to require book reviwers to have no “conflict of interest” regarding the books they review? “To begin with, the world of fiction is pretty small. The number of folks who are any good at writing reviews of fiction is smaller still. By the time you find one willing to review a book, it’s inconceivable that he or she not have preconceived notions about the author, the author’s work, or the proper way to write a novel. A hundred other conflicts may exist: relationships with literary agents, friends, or friends of friends; workplace affiliations; political sympathies, religious views; and on and on. Also, writers are notoriously petty people: I’d wager that nine out of 10 who receive a bad review can discover some undisclosed conflict or conspiracy that caused the reviewer to slag them.”
