For children with IQs in the top .1% Members get access to a listing of other members.
Contacting people with high IQs is generally a good thing, but without additional structure it can easily become a signalling fest. Intelligence is just a capacity of the brain, not a strategy to use it well. It would be like Mensa -- a lot of smart people, most of them doing nothing important.
And -- although I am not completely sure about this -- I suspect that speaking about top 0.1% IQ is methodologically nonsense. It literally means "one in a thousand", so the proper test would require calibrating on tens of thousands or maybe hundreds of tho...
I'm friends with an incredibly smart kid. He's 14, but has been put up three grades in school at one point. He does all the obvious enrichment things which are available in the relatively small Australian city he lives in.
His life experience has been pretty unusual. He doesn't really know what it's like to be challenged in school. All his friends are way older than he is. (Once, I asked him how being constantly around people older than him made him feel. He replied, "Concerned for my future.")
He doesn't know anyone like him, which I think is a shame: he'd probably get along very well with them.
Does anyone know any similar kid geniuses? If so, can I give them my friend's details?
Thanks.
