Also, I didn't say "correlated with intelligence", what I said was more of a cut-off threshold — asserting that one cannot be an actual moron given writing coherently on that scale is more of a boolean than a correlation.
I do need to write more (my own attempt at a novel has been stalled at "why can't I ever be satisfied with how I lead into the dramatic showdown!" for some years now, as none of my attempts have pleased me once written); but as for reading? Well, if you think my taste must result from insufficient breadth and depth, I must wonder what you think of Arthur C. Clarke, Francis Bacon, Larry Niven, Alexandre Dumas, Adrian Tchaikovsky, Neal Stephenson, Robert Heinlein, Alastair Reynolds, Isaac Asimov, Carl Jung, … I'm going to stop there rather than enumerate my whole library, but I can critique each in a different way without resorting to calling them playground insults, even the ones I dislike.
But I will say it was interesting to contrast Chris Hadfield's "An Astronaut's Guide to Life on Earth" with Richard Wiseman's "Shoot for the Moon" — or H. G. Wells with Jules Verne.
