This is a strange one. I have had this argument before. To me, people come up from the ground as they learn. They reach the same point as what I would call normal, just like the rest of us. Here is my argument. In my eyes, they keep learning until they are well above normal people. Unfortunately, it's as if they take the ground with them leaving common sense behind. They forget all the rational common sense things that are important, the things the rest of us remember. Do you remember Sinclair? A genius who brought out the Spectrum computer, pocket tv and a lot of other inventions?
He brought out the Sinclair C5 little car. He was a brain box and the car did as he said. It could travel for miles for a penny or two. What he didn't have the sense to foresee was this. No Businessman would be seen dead in this and neither would any young guy. He would want to impress the girls, not be a laughing stock. The idea lost him millions because he used genius without common sense.

There were a group of these genius people standing near me about a year ago. They were discussing directions. Not one of them was dressed to impress. One was a young girl about 24. Although she had a pretty face, she had no makeup and was dressed in a commonsense way to keep warm as you would expect from a genius. Her hair was simply parted in the middle and slightly shorter than shoulder length.
She just looked like a plain jane, no fashion, just common sense. The worst part, even though her face was pretty, she had like a pea size mole on her cheek and there were three or four near an inch long hairs growing out of it. Any normal intelligence person would never have been seen dead like that. She could probably tell you how far away Mars was and to the inch yet was too thick to groom her face. Yuk.
