Gifted Issues Discussion homepage Forums Identification, Testing & Assessment Non-gifted sibling

It never even occurred to me that siblings would necessarily be very close together in intelligence until I read things on this board.

My sisters probably have an IQ that's two standard deviations lower than mine, at least, so wide discrepancy always struck me as normal.

In fact, my family had siblings that were close together in intelligence compared to another local family.

And my sisters have no learning disabilities.

Granted, I think that the overall families that my parents came from are two standard deviations apart.

My father is not exactly the sharpest tool in the shed.
