Blueprint: How DNA makes us who we are | Robert Plomin, MIT Press, p261.
With a slightly different viewpoint than "She Has Her Mother's Laugh," Blueprint by Robert Plomin gives human genes more influence on who we are. He hopes this will make us all more empathetic than potentially our present default. Given his perspective, Ironic would or should also ascribe the capacity for empathy as primarily influenced by genetics.
In the authors' view, psychotherapy will be a preventive practice focused on your identified inheritable predispositions at some future point.
As the science evolves, Polmin predicts that we will have large enough samples to chart the range of impact your polygenic score accounts for, which he indicates is 50% of who you are. Parents or the home, 25%, and all other factors the balance. In one regard, this view lets parents and schools substantially off the hook. Only in the cases of damaging trauma is this thesis disrupted in his perspective. How can he not consider the corollary given a binary choice?
However, given that variations in thousands of genes combine to contribute to one aspect of who you are and what activates a mutation or doesn't is often environmental, caring about your environment's architecture remains prescient.
Plomin also has odd ideas on education when he notes its purpose is to allow children the "opportunity to find out what they like to do and what they are really good at." No, it is not, nor has this ever been the purpose of education.
In the timeless nature versus nurture debate, Blueprint adds to the discourse unsatisfactorily.
