Not only parenting: genes, temperament, and why care still matters in : the main line · 248

Parenting is not the whole cause — and still not optional When outcomes track genes and peers as well as home life, parents are relieved of omnipotence — and of total blame. That relief is healthy. It does not license neglect. Sensitive care, predictable limits and protected sleep still predict better regulation and safer relationships across many studies.

Think of caregiving as a volume and filter: it rarely invents a trait from nothing, but it can amplify, buffer or channel what is already there. A highly reactive child in a harsh, chaotic home is not the same developmental experiment as that child in a calm, structured one. Gene–environment interplay, without the slogans

Some children are more environmentally sensitive — for better and for worse. Supportive contexts help them thrive; adversity hits them harder. Other children are sturdier across a wider range of climates. Methods that ignore that difference will look “proven” for one child and “useless” for another.
