A True Test of Intelligence

Okay, I can see how solving the riddles in Arkham Asylum is related to intelligence, but the trophies?

I guess you can argue figuring out how to get to the places where The Riddler could means you have some problem solving skills, but I'm pretty sure at least when it comes to some trophies Eddie just flushed them down a sewer...

So I suppose the fact that Batman is wasting his time to find them all does prove something about his intelligence.
