Our brains, therefore, are designed not just to hunt and gather, but also to help us get ahead socially, often via deception and self-deception. But while we may be self-interested schemers, we benefit by pretending otherwise. The less we know about our own ugly motives, the better - and thus we don't like to talk or even think about the extent of our selfishness. This is "the elephant in the brain." Such an introspective taboo makes it hard for us to think clearly about our nature and the explanations for our behavior. The aim of this book, then, is to confront our hidden motives directly - to track down the darker, unexamined corners of our psyches and blast them with floodlights. Then, once everything is clearly visible, we can work to better understand ourselves: Why do we laugh? Why are artists sexy? Why do we brag about travel? Why do we prefer to speak rather than listen?Our unconscious motives drive more than just our private behavior; they also infect our venerated social institutions such as Art, School, Charity, Medicine, Politics, and Religion. In fact, these institutions are in many ways designed to accommodate our hidden motives, to serve covert agendas alongside their "official" ones. The existence of big hidden motives can upend the usual political debates, leading one to question the legitimacy of these social institutions, and of standard policies designed to favor or discourage them. You won't see yourself - or the world - the same after confronting the elephant in the brain.

    To mark the event, National Geographic magazine commissioned seven articles that explore the fascinating issues—including demographics, food security, climate change, fertility trends, managing biodiversity—surrounding this topic, which are collected for the first time in this special ebook.   Envi­ronment editor Robert Kunzig starts by sketching out a natural history of population. The issues associated with population growth seem endless: poverty, food and water supply, world health, climate change, deforestation, fertility rates, and more. In additional chapters Elizabeth Kolbert explores a new era—the “Anthropocene,” or the age of man—defined by our massive impact on the planet, which will endure long after our cities have crumbled; and takes us to the Mediterranean, where she delves into issues associated with increasing ocean acidification. In Bangladesh, Don Belt explores how the people of this crowded region can teach us about adapting to rising sea levels. In “Food Ark” we travel deep within the earth and around the globe to explore the seed banks that are preserving the variety of food species we may need to increase food production on an increasingly crowded planet. In Brazil, Cynthia Gournay explores the phenomenon of “Machisma” and shows how a mix of female empowerment and steamy soap operas helped bring down Brazil’s fertility rate and stoke its vibrant economy. Additionally we explore threats to biodiversity, and the return of cities—which may be the solution to many of our population woes. Join National Geographic on this incredible journey to explore our rapidly growing planet.

    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.

    These numbers don't seem terribly grim, but in ten years, the skewed sex ratio will pose a colossal challenge. By the time those children reach adulthood, their generation will have twenty-four million more men than women.The prognosis for China's neighbors is no less bleak: Asia now has 163 million females "missing" from its population. Gender imbalance reaches far beyond Asia, affecting Georgia, Eastern Europe, and cities in the U.S. where there are significant immigrant populations. The world, therefore, is becoming increasingly male, and this mismatch is likely to create profound social upheaval.Historically, eras in which there have been an excess of men have produced periods of violent conflict and instability. Mara Hvistendahl has written a stunning, impeccably-researched book that does not flinch from examining not only the consequences of the misbegotten policies of sex selection but Western complicity with them.

     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.

    Nobel Peace Prize winner, bestselling author, activist, and political icon, Al Gore has become one of the most respected and influential public intellectuals in America today. The Assault on Reason takes an unprecedented look at how faith in the power of reasonâ€"the idea that citizens can govern themselves through rational debate

    After the horrors of the Nazi regime in WWII, the mainstream scientific world turned its back on eugenics and the study of racial difference. But a worldwide network of eugenicists founded journals and funded research, providing the kind of shoddy studies that were ultimately cited in Richard Hernstein's and Charles Murray's 1994 title, The Bell Curve, which purported to show differences in intelligence among races.Whether you think of racist science as bad science, evil science, alt-right science, or pseudoscience, why would any contemporary scientist imagine that gross inequality is a fact of nature, rather than of political history? Angela Saini's Superior connects the dots, laying bare the history, continuity, and connections of modern racist science, some more subtle than you might think.

    Cacioppo’s groundbreaking research topples one of the pillars of modern medicine and psychology: the focus on the individual as the unit of inquiry. By employing brain scans, monitoring blood pressure, and analyzing immune function, he demonstrates the overpowering influence of social context—a factor so strong that it can alter DNA replication. He defines an unrecognized syndrome—chronic loneliness—brings it out of the shadow of its cousin depression, and shows how this subjective sense of social isolation uniquely disrupts our perceptions, behavior, and physiology, becoming a trap that not only reinforces isolation but can also lead to early death. He gives the lie to the Hobbesian view of human nature as a “war of all against all,” and he shows how social cooperation is, in fact, humanity’s defining characteristic. Most important, he shows how we can break the trap of isolation for our benefit both as individuals and as a society.

    Sapolsky, America's most beloved neurobiologist/primatologist. Organized into three sections, each tackling a Big Question in natural science, Monkeyluv offers a lively exploration of the influence of genes and the environment on behavior; the social and political -- and, of course, sexual -- implications of behavioral biology; and society's shaping of the individual. From the mating rituals of prairie dogs to the practice of religion in the rain forest, the secretion of pheromones to bugs in the brain, Sapolsky brilliantly synthesizes cutting-edge scientific research with wry, erudite observations about the enormous complexity of simply being human. Thoughtful, engaging, and infused with pop-cultural insights, this collection will appeal to the inner monkey in all of us.

    In the past, discoveries often had to wait for the rise of the next generation to see questions in a new light and let go of old truisms. Today, in a world that is defined by a rapid rate of change, staying on the cutting edge has as much to do with shedding outdated notions as adopting new ones. In this spirit, John Brockman, publisher of the online salon Edge.org ("the world's smartest website"—The Guardian), asked 175 of the world's most influential scientists, economists, artists, and philosophers: What scientific idea is ready for retirement?Jared Diamond explores the diverse ways that new ideas emerge * Nassim Nicholas Taleb takes down the standard deviation * Richard Thaler and novelist Ian McEwan reveal the usefulness of "bad" ideas * Steven Pinker dismantles the working theory of human behavior * Richard Dawkins renounces essentialism * Sherry Turkle reevaluates our expectations of artificial intelligence * Physicist Andrei Linde suggests that our universe and its laws may not be as unique as we think * Martin Rees explains why scientific understanding is a limitless goal * Alan Guth rethinks the origins of the universe * Sam Harris argues that our definition of science is too narrow * Nobel Prize winner Frank Wilczek disputes the division between mind and matter * Lawrence Krauss challenges the notion that the laws of physics were preordained * plus contributions from Daniel Goleman, Mihaly Csikszentmihalyi, Nicholas Carr, Rebecca Newberger Goldstein, Matt Ridley, Stewart Brand, Sean Carroll, Daniel C. Dennett, Helen Fisher, Douglas Rushkoff, Lee Smolin, Kevin Kelly, Freeman Dyson, and others.

    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 r�sum�, 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.

    The classic and controversial argument that morality is based in human nature.

    A cutting-edge work that brings together neuropsychology, cognitive science, and Freudian and Jungian approaches to mythology and narrative, Maps of Meaning presents a rich theory that makes the wisdom and meaning of myth accessible to the critical modern mind.

    Misogyny encompasses the Church, witch hunts, sexual theory, Nazism, pro-life campaigners, and finally, today's developing world, where women are increasingly and disproportionately at risk because of radicalized religious beliefs, famine, war, and disease. Extensively researched, highly readable and provocative, this book chronicles an ancient, pervasive and enduring injustice. The questions it poses deal with the fundamentals of human existence — sex, love, violence — that have shaped the lives of humans throughout history, and ultimately limn an abuse of human rights on a nearly unthinkable scale.

    Through its ability to nurture trees, matsutake helps forests to grow in daunting places. It is also an edible delicacy in Japan, where it sometimes commands astronomical prices. In all its contradictions, matsutake offers insights into areas far beyond just mushrooms and addresses a crucial question: what manages to live in the ruins we have made? A tale of diversity within our damaged landscapes, The Mushroom at the End of the World follows one of the strangest commodity chains of our times to explore the unexpected corners of capitalism. Here, we witness the varied and peculiar worlds of matsutake commerce: the worlds of Japanese gourmets, capitalist traders, Hmong jungle fighters, industrial forests, Yi Chinese goat herders, Finnish nature guides, and more. These companions also lead us into fungal ecologies and forest histories to better understand the promise of cohabitation in a time of massive human destruction.By investigating one of the world's most sought-after fungi, The Mushroom at the End of the World presents an original examination into the relation between capitalist destruction and collaborative survival within multispecies landscapes, the prerequisite for continuing life on earth.
