this is why the IQ test doesn't hold up...
there are different areas of intelligence, and he's obviously lacking in the mechanical knowledge.
Agreed. I'm inclined to say that most people are not born from the womb knowing everything there is to know about mechanical... ish things... for lack of a better word. "Hands-on" learning people tend to take an interest in cars for obvious reasons. Visual or literary learners tend to stay away from mechanical stuff because it's boring to them.
And, some people will pick it up watching, some will pick it up by reading, and some by doing. Reading learners will get nothing out of being shown how to change oil... if they're not told why they're changing it and howevery thing else works that it effects.
The "IQ Test" always holds up, but the scale on which it is measured is not set to an international standard. An "IQ", intelligence quotient, as you know, isn't exactly how "smart" you are, it's the ability to percieve patterns, distinguish shapes (differences and similairities), group objects, ideas, and visual images together.
It's not based on what you know from reading or education, it's the ability to see patterns in places others don't. With education and knowledge, this allows high IQ people to make connections between seemingly unrelated things.
But it has a tendency to be true that really "smart" people have no common sense. The smartest guy I know could recite any detail from any class he took, could understand how to do calculus and math just from looking at a solved problem... and all sorts of other crazy things. But man, that guy did some halariously stupid shit. No common sense, at all... whatsoever... and he was a clumsy oaf. Ah, but he's a great guy :biglaugh:
