I have often wondered about "the case" for spending my time reading fiction, feeling guilty for not reading more economics articles, I suppose. But Roald Dahl wonders why anyone would read anything else:
"Why on earth would anyone choose to read an assemblage of detail, a catalogue of facts, when there was so much good fiction around as an alternative? Invention, he declared, was always more interesting than reality." -in Storyteller, by Donald Sturrock, p6
David Evans' personal blog 
And what about ‘truth is stranger than fiction?’ I think fiction is often more honest than non-fiction, especially when people are writing their supposedly non-fictive thoughts on themselves and others in memoir form.
This is a really nice point. I read quite a few memoirs and you see how insistent people feel about portraying themselves in particular ways, whereas fiction really tries to get in people’s heads and hearts. Good fiction, anyway. 🙂
Right! exactly.
