Policy, voluntary, psychological and educational interest in gifted children emerged across Europe in the early twentieth century but surged dramatically in the 1970s and 1980s. This article explores the transnational voluntary circles hoping that gifted youth would bring peace and liberal democracy across Europe in these years. It analyses, also, how such work came into conflict with the expectations of conservative press in Britain: that gifted children would in fact bolster national economic progress. Critically, the article demonstrates that parents and children, drawing on professional and cultural capital, resisted ideas of gifted youth as global assets. Interest in giftedness revealed the growing ‘agency’ of articulate, affluent, middle-class families within the contexts of individualism and neoliberalism, but also its limits. Further, we can and must centre the experiences of young people in our scholarship, to truly understand how ‘agency’ operates within families and beyond.
