VS Naipaul (not a writer I particularly rate) has made some headlines claiming to be able to spot a writer's sex immediately. He also claimed that there are no female writers at all up to his standard.
So try this Guardian quiz. I got 7 out of 10 right. How will you do?
What gives it away? I'm not sure. Many women writers don't dwell on female bodies in the drooling way a certain group of male ones do. I can tell the difference between Austen and Amis, for example, but a lot of it is period, class and subject matter. On similar grounds and generations, it's more difficult. There is linguistic research into gendered language use, but it's not my field at all.
