Important science question that has me stumped.

It is relative. Superman only seems to have superhuman powers because he can do things humans can't do by virtue of having a body that evolved on a planet with greater gravity. He is normal for his home planet. Gravity does not cause a selection for intelligence.

His planet wasn't heavier. He evolved under a different colored sun, so he has super powers under ours.

Or some horseshit like that, anyway.

If he can't solve a quartic equation in his head under a second, he ain't shit...

What makes him really dumb is the way he uses his super powers.
He can do all that amazing stuff, and seems to have good intentions, yet he has to wait for a disaster before he does anything. It's like he can't think for himself.

If I had his powers, I could find good stuff to do and people to help in between disasters.
What if the governments of the world did fuck-all till a disaster happened?

I think he's just an attention junkie. He only helps if it will make the headlines.
How come he doesn't help out with the space-station, for example. They wouldn't miss the shuttle, if he offered to drop off the payloads.

Selfish.

Yeah - a real bastard alright. He could neutralise all the nukes in the world if he wanted to!
