Abstract
Research in neuroscience and epigenetics is prominent in biomedicine and beyond. Some policy makers, health professionals and other citizens have intuited particular implications from these 'social biologies', leveraging them to support policies that many find problematic (e.g., around the early years). This enjoins scholarly attention to the uses to which science is put, but also to how and why biomedical knowledge comes to be imbued with certain kinds of salience (both by 'advocates' and by 'critics').
