Psychologists have long been aware that most people maintain an often irrationally positive outlook on life. In fact, optimism may be crucial to our existence. Tali Sharot’s experiments, research, and findings in cognitive science have contributed to an increased understanding of the biological basis of optimism. In this fascinating exploration, she takes an in-depth, clarifying look at how the brain generates hope and what happens when it fails; how the brains of optimists and pessimists differ; why we are terrible at predicting what will make us happy; how emotions strengthen our ability to recollect; how anticipation and dread affect us; and how our optimistic illusions affect our financial, professional, and emotional decisions.  With its cutting-edge science and its wide-ranging and accessible narrative, The Optimism Bias provides us with startling new insight into the workings of the brain.From the Hardcover edition.

    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.

    scientific community has long led the world in research on such areas as public health, environmental science, and issues affecting quality of life. Our scientists have produced landmark studies on the dangers of DDT, tobacco smoke, acid rain, and global warming. But at the same time, a small yet potent subset of this community leads the world in vehement denial of these dangers.Merchants of Doubt tells the story of how a loose-knit group of high-level scientists and scientific advisers, with deep connections in politics and industry, ran effective campaigns to mislead the public and deny well-established scientific knowledge over four decades. Remarkably, the same individuals surface repeatedly—some of the same figures who have claimed that the science of global warming is "not settled" denied the truth of studies linking smoking to lung cancer, coal smoke to acid rain, and CFCs to the ozone hole. "Doubt is our product," wrote one tobacco executive. These "experts" supplied it.Naomi Oreskes and Erik M. Conway, historians of science, roll back the rug on this dark corner of the American scientific community, showing how ideology and corporate interests, aided by a too-compliant media, have skewed public understanding of some of the most pressing issues of our era.

    A world that is as creative and complex as it is dangerous and disturbing. A world that is much closer than you think.The dark net is an underworld that stretches from popular social media sites to the most secretive corners of the encrypted web. It is a world that frequently appears in newspaper headlines, but one that is little understood, and rarely explored. The Dark Net is a revelatory examination of the internet today, and of its most innovative and dangerous subcultures: trolls and pornographers, drug dealers and hackers, political extremists and computer scientists, Bitcoin programmers and self-harmers, libertarians and vigilantes.Based on extensive first-hand experience, exclusive interviews and shocking documentary evidence, The Dark Net offers a startling glimpse of human nature under the conditions of freedom and anonymity, and shines a light on an enigmatic and ever-changing world.

    In this book, Dr. Sherry Seethaler provides a "bag of tricks" for making sense of science in the news. You'll learn how to think more sensibly about everything from mad cow disease to global warming and make better science-related decisions in both your personal life and as a citizen. You'll begin by understanding how science really works and progresses, and why scientists sometimes disagree. Seethaler helps you assess the possible biases of those who make scientific claims in the media, and place scientific issues in appropriate context, so you can intelligently assess tradeoffs. You'll learn how to determine whether a new study is really meaningful; uncover the difference between cause and mere coincidence; figure out which statistics mean something, and which don't. Finally, drawing on her extensive experience as a science journalist, she reveals the tricks self-interested players use to mislead and confuse you, and points you to sources of information you can actually rely upon. Seethaler's many examples range from genetic engineering of crops to drug treatments for depression, but the techniques she teaches you will be invaluable in understanding any scientific controversy, in any area of science or health.

    Many people think of microbes as germs to be eradicated, but those that live with us—the microbiome—build our bodies, protect our health, shape our identities, and grant us incredible abilities. In this astonishing book, Ed Yong takes us on a grand tour through our microbial partners, and introduces us to the scientists on the front lines of discovery. Yong, whose humor is as evident as his erudition, prompts us to look at ourselves and our animal companions in a new light—less as individuals and more as the interconnected, interdependent multitudes we assuredly are. The microbes in our bodies are part of our immune systems and protect us from disease. Those in cows and termites digest the plants they eat. In the deep oceans, mysterious creatures without mouths or guts depend on microbes for all their energy. Bacteria provide squids with invisibility cloaks, help beetles to bring down forests, and allow worms to cause diseases that afflict millions of people. I Contain Multitudes is the story of these extraordinary partnerships, between the creatures we are familiar with and those we are not. It reveals how we humans are disrupting these partnerships and how we might manipulate them for our own good. It will change both our view of nature and our sense of where we belong in it.

    It governs the lives of microorganisms and galaxies; it shapes the capabilities of our extraordinarily large brains and the fortunes of our economies. Growth is manifested in annual increments of continental crust, a rising gross domestic product, a child's growth chart, the spread of cancerous cells. In this magisterial book, Vaclav Smil offers systematic investigation of growth in nature and society, from tiny organisms to the trajectories of empires and civilizations.Smil takes readers from bacterial invasions through animal metabolisms to megacities and the global economy. He begins with organisms whose mature sizes range from microscopic to enormous, looking at disease-causing microbes, the cultivation of staple crops, and human growth from infancy to adulthood. He examines the growth of energy conversions and man-made objects that enable economic activities—developments that have been essential to civilization. Finally, he looks at growth in complex systems, beginning with the growth of human populations and proceeding to the growth of cities. He considers the challenges of tracing the growth of empires and civilizations, explaining that we can chart the growth of organisms across individual and evolutionary time, but that the progress of societies and economies, not so linear, encompasses both decline and renewal. The trajectory of modern civilization, driven by competing imperatives of material growth and biospheric limits, Smil tells us, remains uncertain.

    . . when it comes to the legacy of this country's war on drugs, we should all share his outrage." --The New York Times Book Review From one of the world's foremost experts on the subject, a powerful argument that the greatest damage from drugs flows from their being illegal, and a hopeful reckoning with the possibility of their use as part of a responsible and happy lifeDr. Carl L. Hart, Ziff Professor at Columbia University and former chair of the Department of Psychology, is one of the world's preeminent experts on the effects of so-called recreational drugs on the human mind and body. Dr. Hart is open about the fact that he uses drugs himself, in a happy balance with the rest of his full and productive life as a colleague, husband, father, and friend. In Drug Use for Grown-Ups, he draws on decades of research and his own personal experience to argue definitively that the criminalization and demonization of drug use--not drugs themselves--have been a tremendous scourge on America, not least in reinforcing this country's enduring structural racism.Dr. Hart did not always have this view. He came of age in one of Miami's most troubled neighborhoods at a time when many ills were being laid at the door of crack cocaine. His initial work as a researcher was aimed at proving that drug use caused bad outcomes. But one problem kept cropping up: the evidence from his research did not support his hypothesis. From inside the massively well-funded research arm of the American war on drugs, he saw how the facts did not support the ideology. The truth was dismissed and distorted in order to keep fear and outrage stoked, the funds rolling in, and Black and brown bodies behind bars.Drug Use for Grown-Ups will be controversial, to be sure: the propaganda war, Dr. Hart argues, has been tremendously effective. Imagine if the only subject of any discussion about driving automobiles was fatal car crashes. Drug Use for Grown-Ups offers a radically different vision: when used responsibly, drugs can enrich and enhance our lives. We have a long way to go, but the vital conversation this book will generate is an extraordinarily important step.

    In that short time, many doctors decide on the likely diagnosis and best treatment. Often, decisions made this way are correct, but at crucial moments they can also be wrong -- with catastrophic consequences. In this myth-shattering book, Jerome Groopman pinpoints the forces and thought processes behind the decisions doctors make. Groopman explores why doctors err and shows when and how they can -- with our help -- avoid snap judgments, embrace uncertainty, communicate effectively, and deploy other skills that can profoundly impact our health. This book is the first to describe in detail the warning signs of erroneous medical thinking and reveal how new technologies may actually hinder accurate diagnoses. How Doctors Think offers direct, intelligent questions patients can ask their doctors to help them get back on track.Groopman draws on a wealth of research, extensive interviews with some of the country’s best doctors, and his own experiences as a doctor and as a patient. He has learned many of the lessons in this book the hard way, from his own mistakes and from errors his doctors made in treating his own debilitating medical problems.How Doctors Think reveals a profound new view of twenty-first-century medical practice, giving doctors and patients the vital information they need to make better judgments together.

    In The Violinist's Thumb, he explores the wonders of the magical building block of life: DNA.There are genes to explain crazy cat ladies, why other people have no fingerprints, and why some people survive nuclear bombs. Genes illuminate everything from JFK's bronze skin (it wasn't a tan) to Einstein's genius. They prove that Neanderthals and humans bred thousands of years more recently than any of us would feel comfortable thinking. They can even allow some people, because of the exceptional flexibility of their thumbs and fingers, to become truly singular violinists. Kean's vibrant storytelling makes science entertaining, explaining human history and whimsy while showing how DNA will influence our species' future.

    Entering a room with stainless-steel tables topped by corpses in body bags is shocking no matter how long you've prepared yourself, but a strange thing happened when Montross met her cadaver. Instead of being disgusted by her, she was utterly intrigued-intrigued by the person the woman once was, humbled by the sacrifice she had made in donating her body to science, fascinated by the strange, unsettling beauty of the human form. They called her Eve. This is the story of Montross and Eve-the student and the subject-and the surprising relationship that grew between them. Body of Work is a mesmerizing, rarely seen glimpse into the day-to-day life of a medical student-yet one that follows naturally in the footsteps of recent highly successful literary renderings of the mysteries of medicine such as Atul Gawande's Complications: A Surgeon's Notes on an Imperfect Science. Christine Montross was a poet long before she became a doctor and brings an uncommon perspective to the emotional difficulty of the first year of medical school-the dispiriting task of remaining clinical and detached while in the anatomy lab and the struggle with the line you've crossed by violating another's body once you leave it. Montross was so affected by her experience with Eve that she undertook to learn more about the history of cadavers and the study of anatomy. She visited an autopsy lab in Ireland and the University of Padua in Italy where Vesalius, a forefather of anatomy, once studied; she learned about body snatchers and grave-robbers and anatomists who practiced their work on live criminals. Her disturbing, often entertaining anecdotes enrich this exquisitely crafted memoir, endowing an eerie beauty to the world of a doctor-in-training. Body of Work is an unforgettable examination of the mysteries of the human body and a remarkable look at our relationship with both the living and the dead.

    So wrong that a chimpanzee choosing answers at random will consistently outguess teachers, journalists, Nobel laureates, and investment bankers.In Factfulness, Professor of International Health and global TED phenomenon Hans Rosling, together with his two long-time collaborators, Anna and Ola, offers a radical new explanation of why this happens. They reveal the ten instincts that distort our perspective—from our tendency to divide the world into two camps (usually some version of us and them) to the way we consume media (where fear rules) to how we perceive progress (believing that most things are getting worse).Our problem is that we don’t know what we don’t know, and even our guesses are informed by unconscious and predictable biases.It turns out that the world, for all its imperfections, is in a much better state than we might think. That doesn’t mean there aren’t real concerns. But when we worry about everything all the time instead of embracing a worldview based on facts, we can lose our ability to focus on the things that threaten us most.Inspiring and revelatory, filled with lively anecdotes and moving stories, Factfulness is an urgent and essential book that will change the way you see the world and empower you to respond to the crises and opportunities of the future.

    That judgment, implausible even to a casual fan, also contradicted the opinion of a growing cadre of neuroscientists who worked in vain to convince the NFL that it was facing a deadly new scourge: A chronic brain disease that was driving an alarming number of players -- including some of the all-time greats -- to madness.League of Denial reveals how the NFL, over a period of nearly two decades, sought to cover up and deny mounting evidence of the connection between football and brain damage.Comprehensively, and for the first time, award-winning ESPN investigative reporters Mark Fainaru-Wada and Steve Fainaru tell the story of a public health crisis that emerged from the playing fields of our 21st century pastime. Everyone knew that football is violent and dangerous. But what the players who built the NFL into a $10 billion industry didn’t know – and what the league sought to shield from them – is that no amount of padding could protect the human brain from the force generated by modern football; that the very essence of the game could be exposing these players to brain damage.In a fast-paced narrative that moves between the NFL trenches, America’s research labs and the boardrooms where the NFL went to war against science, League of Denial examines how the league used its power and resources to attack independent scientists and elevate its own flawed research -- a campaign with echoes of Big Tobacco’s fight to deny the connection between smoking and lung cancer. It chronicles the tragic fates of players like Hall of Fame Pittsburgh Steelers center Mike Webster, who was so disturbed at the time of his death he fantasized about shooting NFL executives; and former Chargers great Junior Seau, whose diseased brain became the target of an unseemly scientific battle between researchers and the NFL. Based on exclusive interviews, previously undisclosed documents and private emails, this is the story of what the NFL knew and when it knew it – questions at the heart of crisis that threatens football, from the highest levels all the way down to Pop Warner.

    It could be an oddball researcher’s genius insight, a catalyzing moment in geopolitical history, a new breakthrough technology, or an unexpected but welcome side effect discovered during clinical trials. Piece together these stories, as Thomas Hager does in this remarkable, century-spanning history, and you can trace the evolution of our culture and the practice of medicine.  ​Beginning with opium, the “joy plant,” which has been used for 10,000 years, Hager tells a captivating story of medicine. His subjects include the largely forgotten female pioneer who introduced smallpox inoculation to Britain, the infamous knockout drops, the first antibiotic, which saved countless lives, the first antipsychotic, which helped empty public mental hospitals, Viagra, statins, and the new frontier of monoclonal antibodies. This is a deep, wide-ranging, and wildly entertaining book.

    Science in the Soul brings together forty-two essays, polemics, and paeans--all written with Dawkins's characteristic erudition, remorseless wit, and unjaded awe of the natural world.Though it spans three decades, this book couldn't be more timely or more urgent. Elected officials have opened the floodgates to prejudices that have for half a century been unacceptable or at least undercover. In a passionate introduction, Dawkins calls on us to insist that reason take center stage and that gut feelings, even when they don't represent the stirred dark waters of xenophobia, misogyny, or other blind prejudice, should stay out of the voting booth. And in the essays themselves, newly annotated by the author, he investigates a number of issues, including the importance of empirical evidence, and decries bad science, religion in the schools, and climate-change deniers.Dawkins has equal ardor for "the sacred truth of nature" and renders here with typical virtuosity the glories and complexities of the natural world. Woven into an exploration of the vastness of geological time, for instance, is the peculiar history of the giant tortoises and the sea turtles--whose journeys between water and land tell us a deeper story about evolution. At this moment, when so many highly placed people still question the fact of evolution, Dawkins asks what Darwin would make of his own legacy--"a mixture of exhilaration and exasperation"--and celebrates science as possessing many of religion's virtues--"explanation, consolation, and uplift"--without its detriments of superstition and prejudice.In a world grown irrational and hostile to facts, Science in the Soul is an essential collection by an indispensable author.Praise for Science in the Soul"Compelling . . . rendered in gloriously spiky and opinionated prose . . . [Dawkins is] one of the great science popularizers of the last half-century."--The Christian Science Monitor "Dawkins is a ferocious polemicist, a defender of reason and enemy of superstition."--John Horgan, Scientific American
