I don't think IQ scores ever tell the whole story.
The longer I've dealt with the concept of giftedness the more I'd agree with this. Yes, I still do believe that a superior IQ is necessary to be considered intellectually gifted, but I also think that a lot of other things play into the level of giftedness than the sheer #s.
For instance, I have one child who is just barely HG on the one IQ test she took years ago. She appears to be much more gifted than that, though, and I don't think that it is b/c the IQ test was a massive underestimation. It was probably not the best estimation for her b/c she wasn't highly cooperative and coming off a really bad school year when tested, but her personality, unusual direction and drive are what make her stand out so much, IMHO.
I don't think that you can necessarily look @ your kids and know which one is higher on IQ based on how they present. My child who presents as more typical likely has a higher IQ (at least she did when tested at the same age as was her sister).
