Neither of us said it means nothing. Of course we think that intelligence levels vary. I think it's more complicated than a simple test and that the test isn't as important in measuring it as you think. I think motivation is much more important to it than you're giving credence. Even then, there's evidence that you can train your IQ. People that participate in more brain stimulating activities tend to do better in the areas related to what's being stimulated.

I also read this article that used George Bush as an example of somebody that had high IQ (in the top 10 percentile) and had self admitted troubles with cognitive ability.
