Adverse Childhood Experiences

The research thread Hillbilly Elegy invokes to give scientific grounding to its account of family instability. J.D. Vance cites the finding that “significant stress in early childhood … result[s] in a hyperresponsive or chronically activated physiologic stress response, along with increased potential for fear and anxiety.” In the book this links the chaos of his upbringing — the fighting, instability, and addiction around him — to lasting physiological and psychological effects, while still pressing his characteristic conclusion that improvement “starts when we stop blaming Obama or Bush or faceless companies and ask ourselves what we can do to make things better.”

Context: Adverse Childhood Experiences (ACEs) are potentially traumatic events in childhood — abuse, neglect, household dysfunction — studied in the landmark CDC-Kaiser ACE Study, which links higher ACE counts to worse adult health and behavioral outcomes.
