> Typical estimates for adult IQ [from twin studies] found it was about 60% genetic, 40% unpredictable, and barely related at all to parenting or family environment.

I’m surprised to the point of near disbelief that home/family environment (early childhood nutrition, sleep hygiene, psychological support [feeling love, trust, and security, etc.], and schooling support) have little effect.

I wonder if that estimate will change again as we learn more.
