meshes well with findings that the more children parents have the less they subscribe to nurture, since they finally, possibly for the first time ever, get some hands on experience with the nurture (nurture as in stuff like upbringing not nurture as in lead paint) versus. nature issue

Interesting - where are these findings reported?

I agree - though since most people have gross misunderstandings of genetics, then they might also think - "Well - they have the same parents and yet they're still so different!"- so then they might ascribe less to heredity too (and more to birth order or certain other environmental influences)
