Let me put this another way: Even if IQ were purely a matter of nurture, it’d still make sense to have ‘gifted children’ programs. Producing a subset of geniuses is more useful to society than spreading those resources out among everybody (where they’d have negligible impact).
the 'gifted and talented program' i went through in middleamerica elementary school was a failed attempt at this. you need gifted teachers to teach gifted kids, and a critical mass of gifted kids. magnet schools solve this distribution problem by centralizing the gifted kids.
