Book excerpt: The Routledge Handbook on Deviance brings together original contributions on deviance, with a focus on new, emerging, and hidden forms of deviant behavior. The editors have curated a comprehensive collection highlighting the relativity of deviance, with chapters exploring the deviant behaviors related to sport, recreation, body modification, chronic health conditions, substance use, religion and cults, political extremism, sexuality, online interaction, mental and emotional disorders, elite societal status, workplace issues, and lifestyle. The selections review competing definitions and orientations and a wide range of theoretical premises while addressing methodological issues involved in the study of deviance. Each section begins with an introduction by the editors, anchoring the topics in relevant theoretical and methodological contexts and identifying common themes as well as divergence. Providing state-of-the-art scholarship on deviance in modern society, this handbook is an invaluable resource for researchers and students engaged in the study of deviance across a range of disciplines including criminology, criminal justice, sociology, anthropology, and interdisciplinary departments, including justice studies, social transformation, and socio-legal studies.
