Some years ago I taught classes on Education of the Gifted at Ohio University. To me the above ratings are naive and do not measure the concept of genius. There are 3 components of giftedness. 1) high IQ; 2) creativity and 3) persistence. I consider persistence to be the most important. A person with reasonably high ability and creativity that really applies themselves can be unstoppable. Personally I believe that the term GENIUS should be reserved for those who have obtained outstanding achievement. It was Thomas Edison, I believe, who said "Genius is 1% inspiration and 99% perspiration."
