QOTW differences in sibling IQs

I see the board is still a bit slow, but of course it's a busy time of year. A short question for this week: do all of your children have IQs that are relatively close together? And are they close to yours/your hubbie's?

A long time ago I read that IQs typically do not differ more than 15 pts among siblings, and I cannot count the number of times people have -already- asked me if my youngest is 'just as gifted' as her two big sisters... Of course I tell them a. it's too early to tell and b. I'm not focusing on it or concerned about it at all. But yes, my oldest two indeed are not far apart in IQ.... and they're above both DH and me (we're 'just' gifted', not extremely...). And then again, the IQ in itself maybe only tells part of the story... because of their different personalities and characteristics we all show our 'giftedness' in very different ways and levels!

I have two girls they are night and day in looks, personality and interests. Yet both are very academic. Enjoy school and being challenged. Their IQ scores are 8 points apart.

I've heard the same thing - that sibling IQs are not supposed to vary much. Anecdotally I've seen both ends of the spectrum, so I think this might be a generality.

personality traits can certainly influence a test score negatively, but I always like to think of high IQ test scores as saying nothing more than 'this child is highly intelligent'. Wether or not something is or can be done with that intelligence, that 'toolbox', and in what way and in what field and in what moment of life, is a whole different story....
