Ren,

For what it's worth, Ruf's work in LOG was pretty much spot on describing my two girls. From the apgar score and alertness at birth, to the early sight reading, santa clause, so on and so on.
I don't consider it "the bible" on gifted and I think most intelligent adults would realize that to do so wouldn't make much sense.
Obviously if it doesn't apply to a child, that doesn't mean the child is not gifted.
I never read the book, probably should. I got my info on her descriptions of LOG she posts online for free.
I'm not convinced she would post the meat of her results for free online if her motivation was purely the pursuit of money.
Besides, I haven't seen her on TV at 3:00a.m.!! smile
But to disregard all of her(Ruf) work because it may not apply to your child, is pretty unscientific as well, I'd think.

Peace,
Incog
