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.

Like few other decisions in life, educational choices must be made by virtually every-one growing up in industrial societies. The consequences of these choices for individual lives are momentous, yet decisions about schooling can be treacherous. They are made during the teen years, at a time when personal preferences are unstable and there is littl

Il fulcro di questo libro è un fatto sorprendente. La jihad estremista non è combattuta da ignoranti o analfabeti, ma da persone che spesso hanno un livello di istruzione universitaria, e che non sono affatto povere. Il fatto ancor più sorprendente è però che gli ingegneri sono sovrarappresentati tra gli estremisti violenti di matrice islamista e fra quelli appartenenti all'estrema destra, mentre sono assenti a sinistra, dove prevalgono i laureati in scienze sociali e in studi umanistici. Quali sono le ragioni per cui gli ingegneri – e non i medici o gli avvocati o gli economisti – hanno molte più probabilità di abbracciare l'estremismo islamista? Nel cercare una risposta, il testo non solo guida il lettore a distinguere la singolare realtà dei fatti dai luoghi comuni sul terrorismo, ma apre nuove e inaspettate prospettive per capire la violenza politica e la natura dell'estremismo.

A groundbreaking investigation into why so many Islamic radicals are engineersThe 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.

The signs and signals of criminal communicationHow 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 résumé, 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.

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.

A taxi driver's life is dangerous work. Picking up a bad customer can leave the driver in a vulnerable position, and erring even once can prove fatal. To protect themselves, taxi drivers must quickly and accurately assess the trustworthiness of complete strangers. In Streetwise, Diego Gambetta and Heather Hamill take this predicament as a prototypical example of many trust decisions, where people must act on limited information and judge another person's trustworthiness based on signs that may or may not be honest indicators of that person's character or intent. Gambetta and Hamill analyze the behavior of cabbies in two cities where driving a taxi is especially perilous: New York City, where drivers have been the targets of frequent and violent robberies, and Belfast, Northern Ireland, a divided metropolis where drivers have been swept up in the region's sectarian violence. Based on in-depth ethnographic research, Streetwise lets drivers describe in their own words how they seek to determine the threat posed by each potential passenger. The drivers'decisions about whom to trust are treated in conjunction with the'sign-management'strategies of their prospective passengers—both genuine passengers who try to persuade drivers of their trustworthiness and the villains who mimic them. As the theory that guides this research suggests, drivers look for signs that correlate closely with trustworthiness but are difficult for an impostor to mimic. A smile, a business suit, or a skullcap alone do not reassure drivers, as any criminal could easily wear them. Only if attached to other signs—a middle-aged woman, a business address, or a synagogue—are they persuasive. Drivers are adept at deciphering deceitful signals, but trickery is occasionally undetectable, so they must adopt defensive strategies to minimize their exposure to harm. In Belfast, where drivers are locals and often have histories of paramilitary involvement,'macho'posturing often serves to deter would-be criminals, while New York cabbies, mostly immigrants who view themselves as outsiders, try simply to minimize the damage from attacks by appeasing robbers and carrying only small amounts of cash. For most people, erring in a trust decision leads to a broken heart or a few dollars lost. For cab drivers, such an error could mean losing their lives. The way drivers negotiate these high stakes offers us vivid insight into how to determine another person's trustworthiness. Written with clarity and color, Streetwise invites the reader to ride shotgun with cabbies as they grapple with a question of relevance to us all: which signs of trustworthiness can we really trust?

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.
