"Book smart. Common sense stupid." Man, have I heard that phrase be told to me a lot in the past. Hmph.
Judging anyone by grades has to be one of the dumbest ways to find out if a person is intelligent or not. There are three different types of learning styles. Those that are visual, auditory and a "kinesthetic" hands-on learner. Someone might learn and understand a concept if they just see it on the board. They can process it and understand it as such. They can look at a instruction book with NO pictures (-twitch-) and figure out how to do it. Some can just hear how it's done and be able to do it verbatimly just by hearing it. However, like me, I'm a blend of all 3 learning styles. I can read over the instructions, hear how it's done but sometimes it doesn't click. I need to physically do it myself to see how it works and to understand it. A helping hand works too. Doesn't mean that either of the learners are stupid, just that they learn and process information in different ways. Why I think the way that the school systems are structured are horribly wrong because they cater to one particular learning style and just assume that the other students will be able to follow suit. If that was the case, my mom, who's a speech pathologist and teaches Special Ed students, would be out of a job. Some people need more help than others.
SATs. Pfft. I refused to take those. I have personal reasons (due to my horrifying fear of doing the Math sections). I said "Fuck that" and went to art college instead to avoid the horrors that numbers give me. But putting a score on someone is absurd. Some people test better than others, doesn't mean they're more intelligent. Just means, like others have said before, they can memorize better. Doesn't mean that they can practically use the concepts that they memorized. Only if you memorize and put what you memorize into practice is when it matters. At least to me. You can teach me an art concept and I can understand it, but if I don't try to physically see how it's put onto paper, I'd just be a walking encyclopedia of information, but no practicality.
I graduated high school with a 3.0 due to laziness and the few times I felt like skipping school to go to NYC.... But I could've gotten at least a 3.5 or higher if I actually studied. I didn't study as hard as some people and still got good grades. Laziness got the best of me though. Gah. High school.
So intelligence to me is a mixture of both common sense, perspective/self awareness of self and others and logic. But judging people based on how well or how fast their mind works makes us all bias twits. I think I'm pretty intelligent outside of book smart now. I could hold a meaningful and thought provoking conversation than sit there and listen to someone rattle on about facts. Yawn. Boring.
I find it hilarious that some people that are so into studies can't really communicate with the general population. When trying to hold a conversation, they come off as socially awkward. Most of the people I dealt with when I switched to a tech major were like that. I can be a social butterfly and trying to have someone that doesn't move from behind their PC try to hit on me has to be one of the funniest moments in my life. Yeah, I'm not friends with him anymore for other reasons though...-shivers-
*Edit: Portal is a great game that makes you think. "If I put this portal at point A can I get to point Z in one jump?" Oh man. The thing you have to do in the game like build momentum and be fast enough to make another portal to go to the spot you are suppose to end up at. Man, game's crazy but sooooo good.
