I've always assumed this to be the case, along with people who get highly-stimulated by reality TV shows, almost like it's their hobby. But on the flip side, I'm slightly jealous of people like this, because I really have to work on difficult projects and put my own (admittedly very average) intelligence to the test in order to get the same reaction they seem to achieve with minimal effort.
I'm just glad I'm not a super-genius; the whole world is probably terribly dull when there's not much else to explore.
