So why does deception play such a prominent role in our everyday lives? In short, why do we deceive?In his bold new work, prominent biological theorist Robert Trivers unflinchingly argues that self-deception evolved in the service of deceit—the better to fool others. We do it for biological reasons—in order to help us survive and procreate. From viruses mimicking host behavior to humans misremembering (sometimes intentionally) the details of a quarrel, science has proven that the deceptive one can always outwit the masses. But we undertake this deception at our own peril.Trivers has written an ambitious investigation into the evolutionary logic of lying and the costs of leaving it unchecked.

    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.

    Masterfully integrating cognitive science, evolutionary psychology, and complexity theory, this intriguing book paints a comprehensive picture of the principles that govern our lives. As Kenrick divulges, beneath our civilized veneer, human beings are a lot like howling hyenas and barking baboons, with heads full of homicidal tendencies and sexual fantasies. But, in his view, many ingrained, apparently irrational behaviors—such as inclinations to one-night stands, racial prejudices, and conspicuous consumption—ultimately manifest what he calls “Deep Rationality.”Although our heads are full of simple selfish biases that evolved to help our ancestors survive, modern human beings are anything but simple and selfish cavemen. Kenrick argues that simple and selfish mental mechanisms we inherited from our ancestors ultimately give rise to the multifaceted social lives that we humans lead today, and to the most positive features of humanity, including generosity, artistic creativity, love, and familial bonds. And out of those simple mechanisms emerge all the complexities of society, including international conflicts and global economic markets. By exploring the nuance of social psychology and the surprising results of his own research, Kenrick offers a detailed picture of what makes us caring, creative, and complex — that is, fully human. Illuminated with stories from Kenrick’s own colorful experiences — from his criminally inclined shantytown Irish relatives, his own multiple high school expulsions, broken marriages, and homicidal fantasies, to his eventual success as an evolutionary psychologist and loving father of two boys separated by 26 years — this book is an exploration of our mental biases and failures, and our mind’s great successes. Idiosyncratic, controversial, and fascinating, Sex, Murder, and the Meaning of Life uncovers the pitfalls and promise of our biological inheritance.

    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.

    It shows how political orientations across space and time arise from three clusters of measurable personality traits. These clusters entail opposing attitudes toward tribalism, inequality, and differing perceptions of human nature. Together, these traits are by far the most powerful cause of left-right voting, even leading people to regularly vote against their economic interests.      As this book explains, our political personalities also influence our likely choice of a mate, and shape society's larger reproductive patterns. Most importantly of all, it tells the evolutionary stories of these crucial personality traits, which stem from epic biological conflicts.     Based on dozens of exciting new insights from primatology, genetics, neuroscience, and anthropology, this groundbreaking work brings core concepts to life through current news stories and personalities. For instance, readers will meet Glenn Beck and Hugo Chavez and come to understand the underlying evolutionary forces they represent. By blending serious research with relevant contemporary examples, Our Political Nature casts important light onto the ideological clashes that so dangerously divide and imperil our world today.

    Among the notorious murderers she has examined are Ted Bundy, Arthur Shawcross, and Mark David Chapman, the man who shot John Lennon. Now she shares her groundbreaking discoveries--and the chilling encounters that led to them.From a juvenile court in Connecticut to the psychiatric wards of New York City's Bellevue Hospital, from maximum security prisons to the corridors of death row, Lewis and her colleague, the eminent neurologist Jonathan Pincus, search to understand the origins of violence. Guilty by Reason of Insanity is an utterly absorbing odyssey that will forever change the way you think about crime, punishment, and the law itself.

    Incorporating the latest advances in brain scanning and neuroscience, Dutton demonstrates that the brilliant neurosurgeon who lacks empathy has more in common with a Ted Bundy who kills for pleasure than we may wish to admit, and that a mugger in a dimly lit parking lot may well, in fact, have the same nerveless poise as a titan of industry.Dutton argues that there are indeed “functional psychopaths” among us—different from their murderous counterparts—who use their detached, unflinching, and charismatic personalities to succeed in mainstream society, and that shockingly, in some fields, the more “psychopathic” people are, the more likely they are to succeed. Dutton deconstructs this often misunderstood diagnosis through bold on-the-ground reporting and original scientific research as he mingles with the criminally insane in a high-security ward, shares a drink with one of the world’s most successful con artists, and undergoes transcranial magnetic stimulation to discover firsthand exactly how it feels to see through the eyes of a psychopath.As Dutton develops his theory that we all possess psychopathic tendencies, he puts forward the argument that society as a whole is more psychopathic than ever: after all, psychopaths tend to be fearless, confident, charming, ruthless, and focused—qualities that are tailor-made for success in the twenty-first century. Provocative at every turn, The Wisdom of Psychopaths is a riveting adventure that reveals that it’s our much-maligned dark side that often conceals the trump cards of success.

    Why do men kill, rape, and wage war, and what can we do about it? Drawing on the latest discoveries about human evolution and about our closest living relatives, the great apes, Demonic Males offers some startling new answers. Dramatic, vivid, and firmly grounded in meticulous research, this book will change the way you see the world. As the San Francisco Chronicle said, it "dares to dig for the roots of a contentious and complicated subject that makes up much of our daily news."

    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 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.

    While sociologists have attributed the trigger of violence to peer pressure, such as bullying and social isolation, prominent psychologist Peter Langman, argues here that psychological causes are responsible.Drawing on 20 years of clinical experience, Langman offers surprising reasons for why some teens become violent. Langman divides shooters into three categories, and he discusses the role of personality, trauma, and psychosis among school shooters.From examining the material evidence of notorious school shooters at Columbine and Virginia Tech to addressing the mental states of the violent youths he treats, Langman shows how to identify early signs of homicide-prone youth and what preventive measures educators, parents and communities can take to protect themselves from the tragedy.

    What it has not done is consider the stark reality that most of the time we humans are thinking about social processes, comparing ourselves to and estimating the intentions of others. In Human, Gazzaniga explores a number of related issues, including what makes human brains unique, the importance of language and art in defining the human condition, the nature of human consciousness, and even artificial intelligence.

     For his groundbreaking sexual research, Alfred Kinsey and his team interviewed 18,000 people, relying on them to honestly report their most intimate experiences. Using the Internet, the neuroscientists Ogas and Gaddam quietly observed the raw sexual behaviors of half a billion people. By combining their observations with neuroscience and animal research, these two young neuroscientists finally answer the long-disputed question: what do people really like? Ogas and Gaddam's findings are transforming the way scientists and therapists think about sexual desire. In their startling book, Ogas and Gaddam analyze a "billion wicked thoughts" on the Internet: a billion Web searches, a million individual search histories, a million erotic stories, a half-million erotic videos, a million Web sites, millions of online personal ads, and many other enormous sources of sexual data in order to understand the true differences between male and female desires, including: ?Men and women have hardwired sexual cues analogous to our hardwired tastes-there are sexual versions of sweet, sour, salty, savory, and bitter. But men and women are wired with different sets of cues. ?The male sexual brain resembles a reckless hunter, while the female sexual brain resembles a cautious detective agency. ?Men form their sexual interests during adolescence and rarely change. Women's sexual interests are plastic and change frequently. ?The male sexual brain is an "or gate": A single stimulus can arouse it. The female sexual brain is an "and gate": It requires many simultaneous stimuli to arouse it. ?When it comes to sexual arousal, men prefer overweight women to underweight women, and a significant number of men seek out erotic images of women in their 40s, 50s, and 60s. ?Women enjoy writing and sharing erotic stories with other women. The fastest growing genre of erotic stories for women are stories about two heterosexual men having sex. ?Though the male sexual brain is much more different from the female sexual brain than is commonly believed, the sexual brain of gay men is virtually identical to that of straight men. Featuring cutting-edge, jaw-dropping science, this wildly entertaining and controversial book helps readers understand their partner's sexual desires with a depth of knowledge unavailable from any other source. Its fascinating and occasionally disturbing findings will rock our modern understanding of sexuality, just as Kinsey's reports did sixty years ago.
