That's kind of what we would expect to happen in the case where other kids get actual support & "gifted" kids are left to fend for themselves, or even sent to the library to keep them from disrupting everyone else.

That would mean that throughout the last 30 years in many places around the world, gifted kids have never been given what they need to capitalize on their gift? Which maybe...

I can't remember where I saw that in the first place, but I'd assume it would have gone off historical data, and hopefully looked across a few different places. So it might be that we never really supported gifted kids, or it could mean that it's a temporary gift.
