This chapter details the ways in which social divisions and inequalities around gender, social class, race/ethnicity, and poverty are embedded and reproduced through early intervention initiatives, especially those invoking brain science. It shows how mothers are envisioned as a risky environment for their children and their outcomes, and held personally accountable for inculcating a ‘biological resistance to adversity’ in their children, able to act as protective buffers between them and harsh social conditions through practising intensive attachment. Poor working-class and minority-ethnic mothers especially are positioned as the source of individual, social, and national problems, and as the solution to them, and the chapter notes the international spread of such ideas.
