In 6th grade we were given a battery of tests spanning a week. I was later told that there were IQ tests, and that I scored 147.
At the age of 63 I took a so-called IQ test on the internet that took about 10 min. and was told I scored 139.
Are either of these relevant? Does it effect my life?
I think that all it does is give you a guess on your potential. A rifle has potential... it could lay in a closet rusting, or be used to bring home food, or for protection or for less pleasant things. It has the same potential no matter how it is actually used.
A man with a 160IQ could do nothing but bad with his life.. use it to get away with anything, or he could apply himself and do great things...IF he was given the tools to use this potential. My 'tools' were my grandmother's lessons about making or fixing anything I needed. That and 'thinking outside the box' (long before it ever became a cute saying).
Those that lived in the Great Depression all learned this in one way or another and my Grandma was great at it. I have never been without her teachings and I can and do tend to make, invent or work around anything I or my family needs. It was not the "IQ" that did this, it was being given the tools of self reliance and confidence. These are the tool I passed on to my own children.
So I don't think the test results are as important as the encouragement that is given an individual to do the best with what they have. A 90IQ person could run rings around a more "gifted" individual if he was encouraged to use what he has to the fullest, while a "gifted" person with no ambition will go nowhere fast. Don't be concerned with your scores as much as what you do with what you have. Always be willing and find enjoyment in learning new things, be willing to think... you would be surprised at how few people actually do that. Your mind is a great tool, use it and you will always be a genius in your own right!
