QAnon has emerged as the defining conspiracy group of our times, and its far-right conspiracies are extraordinary for their breadth and extremity. Bringing together scholars from psychology, sociology, communications, and political science, this cutting-edge volume uses social science theory to investigate aspects of QAnon. Following an introduction to the 'who, what, and why' of QAnon, Part I focuses on the psychological characteristics of QAnon followers and the group's methods for recruiting and maintaining these followers. Part II includes chapters at the intersection of QAnon and society, arguing that society has constructed QAnon as a threat and the social need to belong motivates its followers. Part III discusses the role of communication in promoting and limiting QAnon support, while Part IV concludes by considering the future of QAnon. The Social Science of QAnon is vital reading for scholars and students across the social sciences, and for legal and policy professionals.
