This Handbook examines the study of failure in social sciences, its manifestations in the contemporary world, and the modalities of dealing with it – both in theory and in practice. It draws together a comprehensive approach to failing, and invisible forms of cancelling out and denial of future perspectives. Underlining critical mechanisms for challenging and reimagining norms of success in contemporary society, it allows readers to understand how contemporary regimes of failure are being formed and institutionalized in relation to policy and economic models, such as neo-liberalism. While capturing the diversity of approaches in framing failure, it assesses the conflations and shifts which have occurred in the study of failure over time. Intended for scholars who research processes of inequality and invisibility, this Handbook aims to formulate a critical manifesto and activism agenda for contemporary society. Presenting an integrated view about failure, the Handbook will be an essential reading for students in sociology, social theory, anthropology, international relations and development research, organization theory, public policy, management studies, queer theory, disability studies, sports, and performance research.
