The Routledge Handbook of Collective Intentionality provides a wide-ranging survey of topics in a rapidly expanding area of interdisciplinary research. It consists of 36 chapters written exclusively for this volume by an international team of experts. What is distinctive about the study of collective intentionality within the broader study of social interactions and structures is its focus on the conceptual and psychological features of joint or shared actions and attitudes and their implications for the nature of social groups and their functioning. This Handbook fully captures this distinctive nature of the field and how it subsumes the study of collective action responsibility reasoning thought intention emotion phenomenology decision-making knowledge trust rationality cooperation competition and related issues as well as how these underpin social practices organizations conventions institutions and social ontology. Like the field the Handbook is interdisciplinary drawing on research in philosophy cognitive science linguistics legal theory anthropology sociology computer science psychology economics and political science. Finally the Handbook promotes several specific goals: (1) it provides an important resource for students and researchers interested in collective intentionality; (2) it integrates work across disciplines and areas of research as it helps to define the shape and scope of an emerging area of research; (3) it advances the study of collective intentionality. .
