God no, the world is huge! I know nothing about hinduism compared to a hindu! I wouldn't dare argue with a friend on the intricacies of NASCAR, or another on how to paint. I'm an idiot when in a room of engineers, but a god when a 40K lore discussion comes up. I could never play a mage, and while I swim in a triathlon team i would never try to talk to a sprint-swimmer about lap time.
Intelligence is not just what you know, it's what you don't know. It's context, ability and experience as well as know-how. You may be the best in all of your subjects at high-school, but life has so many lessons to teach that we can never grasp them all. To say you are more intelligent based on your scores in a test displays a saddening lack of intelligence.
You may think yourself smarter than a coal miner, but i have never met a breed of people more stoic and sure of themselves. They don't mess about, they are focused and driven; You may know more about science, math, literature or the arts than 4 of them put together, but they can still make you feel like a fool. You may be smart, but that's a far shot from intelligence.
Am I smart? Not really, but there are one or two fields in which I am confident of my aptitude. Am I intelligent? Sometimes, but i'm intelligent enough to know that the world has very few truly 'stupid' people, and they are never useless despite their niavety or incompetence.
