I noticed such thing that if previous question was estimated to have 60% confidence and the next one is supposed to be 70% I sometimes leave it as 60 due to laziness.

an IQ 220 kid will do just fine in company of other IQ 220 kids and teachers.

If the genetic explanation is true and environment makes no contribution, then I think one should find that IQ is more highly correlated with myopia than academic achievement

It's like saying "if evolution is true, crocoducks should exist". You are (deliberately?) misrepresenting opponent's views. He meant that of all genetic variation affecting IQ, only small, but non-negligible, subset affects both myopia and IQ. However I still don't quite get how larger brain can cause myopia rather than hyperopia.
