I have taken I.Q. tests/elementary school and on my own. I was surprised to find it much higher than I would have predicted.
135-142 (Not high enough to be freakish, but decent.)
I can't say "how I think". I always feel I'm a bit scattered, though not enough to be considered ADD. Often, I suspect the tests were wrong and I'm functioning around educably MR.
I'm now middle-aged (early 40's) and I don't put much stock in these numbers. I think social intelligence, ability to overcome fear/obstacles, and simple "drive" would have been greater gifts. It's not that I'm without any amount of these, but....
I know a man without much education at all. He didn't finish high school. He had a TERRIBLE family (beating, all manner of abuse, neglect) and he's a self-made millionaire. I happen to know his I.Q. has been measured at 115. That's one standard deviation above the norm? High normal.
He began his own business after working as a truck driver. He worked like a dog and acted like he wasn't afraid of anything. He never invested in stock, but rather, bought land all over the place.
So. Hmmm.
