Fight, Flight, Mimic is the first systematic study of deceptive mimicry in the context of wars. Deceptive mimicry -- the manipulation of individual or group identity -- includes passing off as a different individual, as a member of a group to which one does not belong, or, for a group, to ''sign'' its action as another group. Mimicry exploits the reputation of the model it mimics to avoid capture (flight), to strike undetected at the enemy (fight), or to hide behind or besmirch the reputation of the model group (''false flag'' operations). These tactics have previously been described anecdotally, mixed in with other ruses de guerre, but the authors show that mimicry is a distinct form of deception with its own logic and particularly consequential effects on those involved. The book offers a theory and game-theoretic model of mimicry, an overview of its use through history, and a deep empirical exploration of its modern manifestations through several case studies by leading social scientists. The chapters cover mimicry in the context of the Northern Ireland conflict, terrorism campaigns in 1970s Italy, the height of the Iraq insurgency, the Rwandan genocide, the Naxalite rebellion in India, and jihadi discussion forums on the Internet.

Suicide attacks have become the defining act of political violence of our age. From New York City to Baghdad, from Sri Lanka to Israel, few can doubt that they are a terrifying feature of an increasing number of violent conflicts. Since 1981, around 30 organizations throughout the world - some of them secular and others affiliated to radical Islam - have carried out more than 600 suicide missions. Although a tiny fraction of the overall number of guerrilla and terrorist attacks occurring in the same period, the results have proved significantly more lethal. This book is the first to shed real light on these extraordinary acts, and provide answers to the questions we all ask. Are these the actions of aggressive religious zealots and unbridled, irrational radicals or is there a logic driving those behind them? Are their motivations religious or has Islam provided a language to express essentially political causes? How can the perpetrators remain so lucidly effective in the face of certain death? And do these disparate attacks have something like a common cause?For nearly three years, this team of internationally distinguished scholars has pursued an unprejudiced inquiry, investigating organizers and perpetrators alike of this extraordinary phenomenon. Close comparisons between a whole range of cases raise challenging further questions: if suicide missions are so effective, why are they not more common? If killing is what matters, why not stick to 'ordinary' violent means? Or, if dying is what matters, why kill in the process? Making Sense of Suicide Missions contains a wealth of original information and innovative analysis which further our understanding of this chilling feature of the contemporary world in radically new and unexpected ways.

Suicide attacks have become the defining act of political violence of our age. From New York City to Baghdad, from Sri Lanka to Israel, few can doubt that they are a pervasive and terrifying feature of an increasing number of violent conflicts. Since 1981, approximately thirty organizations throughout the world - some of them secular and others affiliated to radical Islam - have carried out more than 500 suicide missions. Although a tiny fraction of the overall number of guerrilla and terrorist attacks occurring in the same period, the results have proved infinitely more lethal. This book is the first to shed real light on these extraordinary acts, and provide answers to the questions we all ask. Are these the actions of aggressive religious zealots and unbridled, irrational radicals or is there a logic driving those behind them? Are their motivations religious or has Islam provided a language to express essentially political causes? How can the perpetrators remain so lucidly effective in the face of certain death? And do these disparate attacks have something like a common cause? For more than two years, this team of internationally distinguished scholars has pursued an unprejudiced inquiry, investigating organizers and perpetrators alike of this extraordinary social phenomenon. Close comparisons between a whole range of cases raise challenging further questions: If suicide missions are so effective, why are they not more common? If killing is what matters, why not stick to 'ordinary' violent means? Or, if dying is what matters, why kill in the process? Making Sense of Suicide Missions contains a wealth of original information and cutting-edge analysis which furthers our understanding of this chilling feature of the contemporary world in radically new and unexpected ways.

This book explores the factors which govern the range of educational decisions confronting individuals between compulsory school education and university. The data on which it draws come from two surveys conducted in north-west Italy, one of unemployed young people and one of high-school pupils. The author is in effect testing the two fundamental and opposed paradigms of explanation which are generally applied in the sociology of education; one which holds that the individual agents are essentially passive, being either constrained by lack of alternatives or pushed by causal factors of which they are unaware; and the other in which they are regarded as capable of purposive action, of weighing the available alternatives with respect to some future rewards.

In a society where trust is in short supply and democracy weak, the Mafia sells protection, a guarantee of safe conduct for parties to commercial transactions. Drawing on the confessions of eight Mafiosi, Diego Gambetta develops an elegant analysis of the economic and political role of the Sicilian Mafia.

The violent actions of a few extremists can alter the course of history, yet there persists a yawning gap between the potential impact of these individuals and what we understand about them. In Engineers of Jihad, Diego Gambetta and Steffen Hertog uncover two unexpected facts, which they imaginatively leverage to narrow that gap: they find that a disproportionate share of Islamist radicals come from an engineering background, and that Islamist and right-wing extremism have more in common than either does with left-wing extremism, in which engineers are absent while social scientists and humanities students are prominent. Searching for an explanation, they tackle four general questions about extremism: Under which socioeconomic conditions do people join extremist groups? Does the profile of extremists reflect how they self-select into extremism or how groups recruit them? Does ideology matter in sorting who joins which group? Lastly, is there a mindset susceptible to certain types of extremism?Using rigorous methods and several new datasets, they explain the link between educational discipline and type of radicalism by looking at two key factors: the social mobility (or lack thereof) for engineers in the Muslim world, and a particular mindset seeking order and hierarchy that is found more frequently among engineers. Engineers' presence in some extremist groups and not others, the authors argue, is a proxy for individual traits that may account for the much larger question of selective recruitment to radical activism. Opening up markedly new perspectives on the motivations of political violence, Engineers of Jihad yields unexpected answers about the nature and emergence of extremism.

How do criminals communicate with each other? Unlike the rest of us, people planning crimes can't freely advertise their goods and services, nor can they rely on formal institutions to settle disputes and certify quality. They face uniquely intense dilemmas as they grapple with the basic problems of whom to trust, how to make themselves trusted, and how to handle information without being detected by rivals or police. In this book, one of the world's leading scholars of the mafia ranges from ancient Rome to the gangs of modern Japan, from the prisons of Western countries to terrorist and pedophile rings, to explain how despite these constraints, many criminals successfully stay in business. Diego Gambetta shows that as villains balance the lure of criminal reward against the fear of dire punishment, they are inspired to unexpected feats of subtlety and ingenuity in communication.He uncovers the logic of the often bizarre ways in which inveterate and occasional criminals solve their dilemmas, such as why the tattoos and scars etched on a criminal's body function as lines on a professional resume, why inmates resort to violence to establish their position in the prison pecking order, and why mobsters are partial to nicknames and imitate the behavior they see in mafia movies. Even deliberate self-harm and the disclosure of their crimes are strategically employed by criminals to convey important messages. By deciphering how criminals signal to each other in a lawless universe, this gruesomely entertaining and incisive book provides a quantum leap in our ability to make sense of their actions.
