Fiction as a Personality Test
At Futurismic: the economics of fiction are not about pensions but about personality.
The point is also raised that fiction can in some cases have intrinsic cognitive value as well, but the central idea - that your taste in fiction is an external signal about the sort of person you are - is an interesting one, especially for fans of genre fiction like ourselves.
If I weren’t writing a story at the moment, I’d be tempted to put together a subgenre enneagram.
