> Is "non-shared environment" basically the "everything else" category after genetics and shared environment have been controlled for? Yes. For instance, in a study of childhood development, "shared environment" is the things that can plausibly be controlled since they are inflicted on all children in a family (e.g., household income, or frequency of family dinners), and "non-shared environment" is the "other" category that captures the infinite number of uncontrolled influences that different children within the family experience differently (e.g., having a scary fall down the stairs).
