Guardian has put up the Naipaul Test here. The idea is to identify whether the writer of a passage is male or female on excerpts from famous male/female authors. If you answer right on all, well, you are rightly and truly Naipaul-ean.
If not, better brush up on your Naipaul quotient. Get back on the books gathering dust in your library shelf.
