This new edition of John Horgan's critically acclaimed book is fully revised and expanded. The book presents a critical analysis of our existing knowledge and understanding of terrorist psychology. Despite the on-going search for a terrorist pathology, the most insightful and evidence-based research to date not only illustrates the lack of any identifiable psychopathology in terrorists, but demonstrates how frighteningly 'normal' and unremarkable in psychological terms are those who engage in terrorist activity. By producing a clearer map of the processes that impinge upon the individual terrorist, a different type of terrorist psychology emerges, one which has clearer implications for efforts at countering and disrupting violent extremism in today's world. In this 2nd edition, Horgan further develops his approach to the arc of terrorism by delving deeper into his IED model of Involvement, Engagement and Disengagement – the three phases of terrorism experienced by every single terrorist. Drawing on new and exciting research from the past decade, with new details from interviews with terrorists ranging from al-Qaeda to left-wing revolutionaries, biographies and autobiographies of former terrorists, and insights from historic and contemporary terrorist attacks since 2005, Horgan presents a fully revised and expanded edition of his signature text. This new edition of The Psychology of Terrorism will be essential reading for students of terrorism and political violence, and counterterrorism studies, and recommended for forensic psychology, criminology, international security and IR in general.

In compiling this annotated bibliography on the psychology of terrorism, the author has defined terrorism as "acts of violence intentionally perpetrated on civilian noncombatants with the goal of furthering some ideological, religious or political objective." The principal focus is on nonstate actors. The task was to identify and analyze the scientific and professional social science literature pertaining to the psychological and/or behavioral dimensions of terrorist behavior (not on victimization or effects). The objectives were to explore what questions pertaining to terrorist groups and behavior had been asked by social science researchers; to identify the main findings from that research; and attempt to distill and summarize them within a framework of operationally relevant questions. To identify the relevant social science literature, the author began by searching a series of major academic databases using a systematic, iterative keyword strategy, mapping, where possible, onto existing subject headings. The focus was on locating professional social science literature published in major books or in peer-reviewed journals. Searches were conducted of the following databases October 2003: Sociofile/Sociological Abstracts, Criminal Justice Abstracts (CJ Abstracts), Criminal Justice Periodical Index (CJPI), National Criminal Justice Reference Service Abstracts (NCJRS), PsycInfo, Medline, and Public Affairs Information Service (PAIS). Three types of annotations were provided for works in this bibliography: Author's Abstract -- this is the abstract of the work as provided (and often published) by the author; Editor's Annotation -- this is an annotation written by the editor of this bibliography; and Key Quote Summary -- this is an annotation composed of "key quotes" from the original work, edited to provide a cogent overview of its main points.

Responding directly to the terrorist attacks of September 11, 2001, an outstanding interdisciplinary group of academics, clinicians, and activists from around the world united to produce this clear exploration of terrorism.

Publisher description

The psychology of terrorism, in its most basic form, is about fear. The purposes of this book are to unpack the complexity of terrorism fears and to present a new paradigm for understanding the psychology of terrorism.

This book explores the evolutionary context of terrorism and political violence. While evolutionary thinking has come to permeate both biological and social-science theorising, it has not yet been applied systematically to the areas of terrorism and political violence. This volume seeks to do this for the first time. It presents a collection of essays on evolutionary psychology and terrorism, which encourage the reader to approach terrorism from a non-traditional perspective, by developing new approaches to understanding it and those who commit such acts of violence. The book identifies evolutionary thought as heuristically important in the understanding of terrorism, explores the key conceptual themes, and provides an evolutionary (and cross-species) understanding of the community-wide effects of terrorist attacks. The contributors bring forward innovative ideas and concepts to assist the practitioner, analyst and academic to better understand and respond to the threat of terrorism. In doing so this book challenges existing assumptions about terrorism and those who carry out such acts, in order to move the debate into new areas characterized by an emphasis on intellectual quality and rigour, an interdisciplinary approach, and a drawing together of theory and practice. The intention is to provide a sufficient discussion to enable the reader to both understand the relevance of evolutionary thinking to terrorism and political violence, and to appreciate the practical implications of conceptualising problems in this way. This book will be of much interest to students of terrorism and political violence, psychology, criminology and security studies.

This accessible new book looks at how and why individuals leave terrorist movements, and considers the lessons and implications that emerge from this process. Focusing on the tipping points for disengagement from groups such as Al Qaeda, the IRA and the UVF, this volume is informed by the dramatic and sometimes extraordinary accounts that the terrorists themselves offered to the author about why they left terrorism behind. The book examines three major issues: what we currently know about de-radicalisation and disengagement how discussions with terrorists about their experiences of disengagement can show how exit routes come about, and how they then fare as ‘ex-terrorists’ away from the structures that protected them what the implications of these findings are for law-enforcement officers, policy-makers and civil society on a global scale. Concluding with a series of thought-provoking yet controversial suggestions for future efforts at controlling terrorist behaviour, Walking Away From Terrorism provides an comprehensive introduction to disengagement and de-radicalisation and offers policymakers a series of considerations for the development of counter-radicalization and de-radicalisation processes. This book will be essential reading for students of terrorism and political violence, war and conflict studies, security studies and political psychology. John Horgan is Director of the International Center for the Study of Terrorism at the Pennsylvania State University. He is one of the world's leading experts on terrorist psychology, and has authored over 50 publications in this field; recent books include the The Psychology of Terrorism (Routledge 2005) and Leaving Terrorism Behind (co-edited, Routledge 2008)
