Here, for the first time and in detail, Zimbardo tells the full story of the Stanford Prison Experiment, the landmark study in which a group of college-student volunteers was randomly divided into “guards” and “inmates” and then placed in a mock prison environment. Within a week, the study was abandoned, as ordinary college students were transformed into either brutal, sadistic guards or emotionally broken prisoners. By illuminating the psychological causes behind such disturbing metamorphoses, Zimbardo enables us to better understand a variety of harrowing phenomena, from corporate malfeasance to organized genocide to how once upstanding American soldiers came to abuse and torture Iraqi detainees in Abu Ghraib. He replaces the long-held notion of the “bad apple” with that of the “bad barrel”—the idea that the social setting and the system contaminate the individual, rather than the other way around.

    In some cases, this absence can be dangerous, but in others it can simply mean a different way of seeing the world.In The Science of Evil Simon Baron-Cohen, an award-winning British researcher who has investigated psychology and autism for decades, develops a new brain-based theory of human cruelty. A true psychologist, however, he examines social and environmental factors that can erode empathy, including neglect and abuse.Based largely on Baron-Cohen's own research, The Science of Evil will change the way we understand and treat human cruelty.

    In The Anatomy of Violence, Raine dissects the criminal mind with a fascinating, readable, and far-reaching scientific journey into the body of evidence that reveals the brain to be a key culprit in crime causation.  Raine documents from genetic research that the seeds of sin are sown early in life, giving rise to abnormal physiological functioning that cultivates crime. Drawing on classical case studies of well-known killers in history—including Richard Speck, Ted Kaczynski, and Henry Lee Lucas—Raine illustrates how impairments to brain areas controlling our ability to experience fear, make good decisions, and feel guilt predispose us to violence. He contends that killers can actually be coldhearted: something as simple as a low resting heart rate can give rise to violence. But arguing that biology is not destiny, he also sketches out provocative new biosocial treatment approaches that can change the brain and prevent violence.  Finally, Raine tackles the thorny legal and ethical dilemmas posed by his research, visualizing a futuristic brave new world where our increasing ability to identify violent offenders early in life might shape crime-prevention policies, for good and bad. Will we sacrifice our notions of privacy and civil rights to identify children as potential killers in the hopes of helping both offenders and victims? How should we punish individuals with little to no control over their violent behavior? And should parenting require a license? The Anatomy of Violence offers a revolutionary appraisal of our understanding of criminal offending, while also raising provocative questions that challenge our core human values of free will, responsibility, and punishment.From the Hardcover edition.

    Some system of authority is a requirement of all communal living, and it is only the man dwelling in isolation who is not forced to respond, through defiance or submission, to the commands of others. Obedience, as a determinant of behavior is of particular relevance to our time. It has been reliably established that from 1933 to 1945 millions of innocent people were systematically slaughtered on command. Gas chambers were built, death camps were guarded, daily quotas of corpses were produced with the same efficiency as the manufacture of appliances. These inhumane policies may have originated in the mind of a single person, but they could only have been carried out on a massive scale if a very large number of people obeyed orders.Obedience is the psychological mechanism that links individual action to political purpose. It is the dispositional cement that binds men to systems of authority. Facts of recent history and observation in daily life suggest that for many people obedience may be a deeply ingrained behavior tendency, indeed, a prepotent impulse overriding training in ethics, sympathy, and moral conduct. C. P. Snow (1961) points to its importance when he writes:When you think of the long and gloomy history of man, you will find more hideous crimes have been committed in the name of obedience than have ever been committed in the name of rebellion. If you doubt that, read William Sbirer's 'Rise and Fall of the Third Reich.' The German Officer Corps were brought up in the most rigorous code of obedience . . . in the name of obedience they were party to, andassisted in, the most wicked large scale actions in the history of the world. (p. 24)The Nazi extermination of European Jews is the most extremeinstance of abhorrent immoral acts carried out by thousands ofpeople in the name of obedience. Yet in lesser degree this type ofthing is constantly recurring: ordinary citizens are ordered todestroy other people, and they do so because they consider ittheir duty to obey orders. Thus, obedience to authority, longpraised as a virtue, takes on a new aspect when it serves amalevolent cause; far from appearing as a virtue, it is transformedinto a heinous sin. Or is it?The moral question of whether one should obey when commands conflict with conscience was argued by Plato, dramatized in "Antigone," and treated to philosophic analysis in every historical epoch Conservative philosophers argue that the very fabric of society is threatened by disobedience, and even when the act prescribed by an authority is an evil one, it is better to carry out the act than to wrench at the structure of authority. Hobbes stated further that an act so executed is in no sense the responsibility of the person who carries it out but only of the authority that orders it. But humanists argue for the primacy of individual conscience in such matters, insisting that the moral judgments of the individual must override authority when the two are in conflict.The legal and philosophic aspects of obedience are of enormous import, but an empirically grounded scientist eventually comes to the point where he wishes to move from abstract discourse to the careful observation of concrete instances. In order to take a close look at the act of obeying, I set up a simple experimentat Yale University. Eventually, the experiment was to involve more than a thousand participants and would be repeated at several universities, but at the beginning, the conception was simple. A person comes to a psychological laboratory and is told to carry out a series of acts that come increasingly into conflict with conscience. The main question is how far the participant will comply with the experimenter's instructions before refusing to carry out the actions required of him.But the reader needs to know a little more detail about the experiment. Two people come to a psychology laboratory to take part in a study of memory and learning. One of them is designated as a "teacher" and the other a "learner." The experimenter explains that the study is concerned with the effects of punishment on learning. The learner is conducted into a room, seated in a chair, his arms strapped to prevent excessive movement, and an electrode attached to his wrist. He is told that he is to learn a list of word pairs; whenever he makes an error, be will receive electric shocks of increasing intensity.The real focus of the experiment is the teacher. After watching the learner being strapped into place, he is taken into the main experimental room and seated before an impressive shock generator. Its main feature is a horizontal line of thirty switches, ranging from 15 volts to 450 volts, in 15-volt increments. There are also verbal designations which range from Slight SHOCK to Danger--Severe SHOCK. The teacher is told that he is to administer the learning test to the man in the other room. When the learner responds correctly, the teacher moves on to the next item; when the other man gives an incorrectanswer, the teacher is to give him an electric shock. He is to start at the lowest shock level ( 15 volts) and to increase the level each time the man makes an error, going through 30 volts, 45 volts, and so on.The "teacher" is a genuinely naive subject who has come to the laboratory to participate in an experiment. The learner, or victim, is an actor who actually receives no shock at all. The point of the experiment is to see how far a person will proceed in a concrete and measurable situation in which he is ordered to inflict increasing pain on a protesting victim.

    But armies have developed sophisticated ways of overcoming this instinctive aversion. And contemporary civilian society, particularly the media, replicates the army's conditioning techniques, and, according to Lt. Col. Dave Grossman's thesis, is responsible for our rising rate of murder among the young.Upon its initial publication, On Killing was hailed as a landmark study of the techniques the military uses to overcome the powerful reluctance to kill, of how killing affects soldiers, and of the societal implications of escalating violence. Now, Grossman has updated this classic work to include information on 21st-century military conflicts, recent trends in crime, suicide bombings, school shootings, and more. The result is a work certain to be relevant and important for decades to come.

    Many of us take for granted that babies are born selfish and that it is the role of society—and especially parents—to transform them from little sociopaths into civilized beings. In Just Babies, Paul Bloom argues that humans are in fact hardwired with a sense of morality. Drawing on groundbreaking research at Yale, Bloom demonstrates that, even before they can speak or walk, babies judge the goodness and badness of others’ actions; feel empathy and compassion; act to soothe those in distress; and have a rudimentary sense of justice.Still, this innate morality is limited, sometimes tragically. We are naturally hostile to strangers, prone to parochialism and bigotry. Bringing together insights from psychology, behavioral economics, evolutionary biology, and philosophy, Bloom explores how we have come to surpass these limitations. Along the way, he examines the morality of chimpanzees, violent psychopaths, religious extremists, and Ivy League professors, and explores our often puzzling moral feelings about sex, politics, religion, and race.

    In his gripping and controversial new work, New York Times bestselling author Steven Pinker shows that despite the ceaseless news about war, crime, and terrorism, violence has actually been in decline over long stretches of history. Exploding myths about humankind's inherent violence and the curse of modernity, this ambitious book continues Pinker's exploration of the essence of human nature, mixing psychology and history to provide a remarkable picture of an increasingly enlightened world.

    How do they do it? Why are they successful? And what keeps us falling for it, over and over again? These are the questions that journalist and psychologist Maria Konnikova tackles in her mesmerizing new book.   From multimillion-dollar Ponzi schemes to small-time frauds, Konnikova pulls together a selection of fascinating stories to demonstrate what all cons share in common, drawing on scientific, dramatic, and psychological perspectives. Insightful and gripping, the book brings readers into the world of the con, examining the relationship between artist and victim. The Confidence Game asks not only why we believe con artists, but also examines the very act of believing and how our sense of truth can be manipulated by those around us.

     His starting point is moral intuition—the nearly instantaneous perceptions we all have about other people and the things they do. These intuitions feel like self-evident truths, making us righteously certain that those who see things differently are wrong. Haidt shows us how these intuitions differ across cultures, including the cultures of the political left and right. He blends his own research findings with those of anthropologists, historians, and other psychologists to draw a map of the moral domain. He then examines the origins of morality, overturning the view that evolution made us fundamentally selfish creatures. But rather than arguing that we are innately altruistic, he makes a more subtle claim—that we are fundamentally groupish. It is our groupishness, he explains, that leads to our greatest joys, our religious divisions, and our political affiliations. In a stunning final chapter on ideology and civility, Haidt shows what each side is right about, and why we need the insights of liberals, conservatives, and libertarians to flourish as a nation.

    Stone—host of Discovery Channel’s former series Most Evil—uses this common emotional reaction to horrifying acts as his starting point to explore the concept and reality of evil from a new perspective. In an in-depth discussion of the personality traits and behavior that constitute evil across a wide spectrum, Dr. Stone takes a clarifying scientific approach to a topic that for centuries has been inadequately explained by religious doctrines.Basing his analysis on the detailed biographies of more than 600 violent criminals, Stone has created a 22-level hierarchy of evil behavior, which loosely reflects the structure of Dante’s Inferno. He traces two salient personality traits that run the gamut from those who commit crimes of passion to perpetrators of the worst crimes—sadistic torture and murder. One trait is narcissism, as exhibited in people who are so self-centered that they have little or no ability to care about their victims. The other is aggression, the use of power over another person to inflict humiliation, suffering, and death.Stone then turns to the various factors that, singly or intertwined, contribute to pushing certain people over the edge into committing heinous crimes. They include heredity, adverse environments, violence-prone cultures, mental illness or brain injury, and abuse of mind-altering drugs. All are considered in the search for the root causes of evil behavior.What do psychology, psychiatry, and neuroscience tell us about the minds of those whose actions could be described as evil? And what will that mean for the rest of us? Stone discusses how an increased understanding of the causes of evil will affect the justice system. He predicts a day when certain persons can safely be declared salvageable and restored to society and when early signs of violence in children may be corrected before potentially dangerous patterns become entrenched.

    In bold contrast to the predominant Freudian school of thought, Becker tackles the problem of the vital lie -- man's refusal to acknowledge his own mortality. In doing so, he sheds new light on the nature of humanity and issues a call to life and its living that still resonates more than twenty years after its writing.

    In fact, he points out, our cooperative instincts may have evolved as part of mankind?s natural selfish behavior--by exchanging favors we can benefit ourselves as well as others.Brilliantly orchestrating the newest findings of geneticists, psychologists, and anthropologists, The Origins of Virtue re-examines the everyday assumptions upon which we base our actions towards others, whether in our roles as parents, siblings, or trade partners. With the wit and brilliance of The Red Queen, his acclaimed study of human and animal sexuality, Matt Ridley shows us how breakthroughs in computer programming, microbiology, and economics have given us a new perspective on how and why we relate to each other.

    With their flagrant criminal violation of society's rules, serial killers like Ted Bundy and John Wayne Gacy are among the most dramatic examples of the psychopath. Individuals with this personality disorder are fully aware of the consequences of their actions and know the difference between right and wrong, yet they are terrifyingly self-centered, remorseless, and unable to care about the feelings of others. Perhaps most frightening, they often seem completely normal to unsuspecting targets--and they do not always ply their trade by killing. Presenting a compelling portrait of these dangerous men and women based on 25 years of distinguished scientific research, Dr. Robert D. Hare vividly describes a world of con artists, hustlers, rapists, and other predators who charm, lie, and manipulate their way through life. Are psychopaths mad, or simply bad? How can they be recognized? And how can we protect ourselves? This book provides solid information and surprising insights for anyone seeking to understand this devastating condition.

    Through vivid narrative, lively presentations of important research, and intriguing examples, Elliot Aronson probes the patterns and motives of human behavior, covering such diverse topics as terrorism, conformity, obedience, politics, race relations, advertising, war, interpersonal attraction, and the power of religious cults.

    If reason is so useful, why didn't it also evolve in other animals? If reason is that reliable, why do we produce so much thoroughly reasoned nonsense? In their groundbreaking account of the evolution and workings of reason, Hugo Mercier and Dan Sperber set out to solve this double enigma. Reason, they argue with a compelling mix of real-life and experimental evidence, is not geared to solitary use, to arriving at better beliefs and decisions on our own. What reason does, rather, is help us justify our beliefs and actions to others, convince them through argumentation, and evaluate the justifications and arguments that others address to us.In other words, reason helps humans better exploit their uniquely rich social environment. This interactionist interpretation explains why reason may have evolved and how it fits with other cognitive mechanisms. It makes sense of strengths and weaknesses that have long puzzled philosophers and psychologists--why reason is biased in favor of what we already believe, why it may lead to terrible ideas and yet is indispensable to spreading good ones.Ambitious, provocative, and entertaining, The Enigma of Reason will spark debate among psychologists and philosophers, and make many reasonable people rethink their own thinking.
