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!

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....

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.

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.

That's funny you should mention that Ann, your DDs sound a lot like my oldest two. Our oldest is besides very creative also not the talkative type. When she was tested I was almost sure she'd show a big difference in the verbal and performing halfs of the test, the verbal being less strong. How wrong I was... she got ceiling scores in both fields.... but apparently she just uses her verbal skills differently... She's the one underachieving tremendously in perspective to her IQ, but she's quite content, always busy making things, and likes to blend in in school, so I let her... Our second DD gets better grades as she shows more 'reproductive' powers... DD1s powers can be found more in combining elements in surprising ways for new insights, not so much remembering details and being able to reproduce them on command....

Our story is similar to yours. We have 2 older girls who have tested as gifed, and a 2 yr old who is a bright joyful child (way too early to tell but is very similar to her sisters). Both dh and I tested as gifted as students.
