There are four kinds of inteligence in my opinion, one of which is the most important - but often ignored, social, academic, common, and logical.
Social Inteligence is self explanitory.
Academic means you can test well - hence IQ Test.
Common Inteligence - You can do it, but you must work for it.
Logical - You can find the basic component of any problem, even if your not majorly knowledgeable on the thing - break it down and solve the 'jist of it.
Unfortunatly we live in a world based on academic and social inteligence. Academic because there is written documentation, and social because that is how you work with others so it too can be recorded.
I think many lack Academic Inteligence.
I believe a larger portion of computer people contain logical inteligence.
Any girl with a cell phone lacks common inteligence - especially when behind the wheel.
