I've always taken comfort from the fact that my two boys were different on day zero. This tells me that although I have a great deal of influence on them, it isn't all up to me: it's both nurture and nature. (Takes a bit of the pressure off.)
Yes, but outcomes are largely multi-realisable. It’s true that nature has a big role to play, but I think a lot of that role is expressed in how it changes nurture dynamics.
A shy child might not develop productive, healthy confrontation and resolution skills if nurture isn’t sensitive to that factor and willing to create an environment where those skills are learned.
My nature affected my parents nurture, as well as my other caregivers, mentors, and teachers. I think that’s the more significant role of nature. Nurturers could be much more attuned to this and more mindfully think through how to test for and pursue the right end goals, given different natures.
