Foresight

All the time we make predictions of the future, many of these never come true and we forget them (until somebody points out what an idiot we were for not signing up Astrid Lindgren or the Beatles). But if you make sufficiently many predictions, some of them will of course come true, and some of these uncannily so.

I've always been struck by how similar to Ronald Reagan president Prexy in John Brunner's The Sheep Look up was, long before Reagan's ascendancy to the presidency. But even more startlingly prophetic is The Onion's satire of George W Bush, just after the 2000 elections: Our Long National Nightmare Of Peace And Prosperity Is Finally Over.
