The Selfish Brain

The Selfish Brain explains how individuals and communities are affected by drugs such as alcohol, tobacco, marijuana, cocaine, and heroin, and how treatment can lead to whole healthy, lives. Why is the brain so vulnerable to the effects of alcohol and other drugs? How does addiction echo through families, cultures, and history? What is it that families and communities do to promote or prevent addiction?These are some of the questions that this thorough, thoughtful, and well-reasoned book answers--in clear, comprehensible terms. From the basics of brain chemistry to the workings of particular drugs such as alcohol, tobacco, marijuana, cocaine, and heroin, The Selfish Brain explains how individuals and communities become trapped in destructive habits--and how various treatments and approaches lead to recovery and whole, healthy lives.

In The Selfish Brain, which has been written with non-economists in mind, expands on Richard McKenzie's development of "brain-centric economics," which provides a new way of assessing and reconciling (albeit partially) the growing conflict between conventional or neoclassical economics (represented by the work of Nobel Laureates Milton Friedman and Gary Becker) and behavioral economics (represented by the work of Nobel Laureates Daniel Kahneman and Richard Thaler). In the book, McKenzie uses conventional economic analytics to explain how and why many behaviorists' findings of widespread decision "irrationalities" and "biases" have a rational foundation. He is also able to develop many economic insights that conventional economists have missed, for example, how the gains from open trade are greater than Adam Smith and his followers have realized. He accomplishes such ends by first recognizing that the human brain, while powerful, is the one of the scarcest of all resources in the universe and by realizing that the brain faces a serious economic problem, that of allocating as carefully and judiciously as it can its limited mental resources to achieve its most valuable ends. The human brain is seen as the ultimate seat of rational decision making. Adam Smith famously wrote that people have a "propensity to truck, barter, and exchange," without giving a source of the propensity. McKenzie provides the source, the brain's scarcity problem. The brain seeks to accommodate its excess demands by seeking to specialize in its decision making and then searching out trades. Richard McKenzie, who has published widely, is the Walter B. Gerken Professor of Economics (ret.) in the Merage School of Business at the University of California, Irvine.

Science need not be dull and bogged down by jargon, as Richard Dawkins proves in this entertaining look at evolution. The themes he takes up are the concepts of altruistic and selfish behaviour; the genetical definition of selfish interest; the evolution of aggressive behaviour; kinshiptheory; sex ratio theory; reciprocal altruism; deceit; and the natural selection of sex differences. 'Should be read, can be read by almost anyone. It describes with great skill a new face of the theory of evolution.' W.D. Hamilton, Science

Human beings are primates, and primates are political animals. 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.

God is great—for your mental, physical, and spiritual health. Based on new evidence culled from brain-scan studies, a wide-reaching survey of people’s religious and spiritual experiences, and the authors’ analyses of adult drawings of God, neuroscientist Andrew Newberg and therapist Mark Robert Waldman offer the following breakthrough discoveries: • Not only do prayer and spiritual practice reduce stress, but just twelve minutes of meditation per day may slow down the aging process. • Contemplating a loving God rather than a punitive God reduces anxiety and depression and increases feelings of security, compassion, and love. • Fundamentalism, in and of itself, can be personally beneficial, but the prejudice generated by extreme beliefs can permanently damage your brain. • Intense prayer and meditation permanently change numerous structures and functions in the brain, altering your values and the way you perceive reality. Both a revelatory work of modern science and a practical guide for readers to enhance their physical and emotional health, How God Changes Your Brain is a first-of-a-kind book about faith that is as credible as it is inspiring.

We are profoundly social creatures--more than we know. In Social, renowned psychologist Matthew Lieberman explores groundbreaking research in social neuroscience revealing that our need to connect with other people is even more fundamental, more basic, than our need for food or shelter. Because of this, our brain uses its spare time to learn about the social world--other people and our relation to them. It is believed that we must commit 10,000 hours to master a skill. According to Lieberman, each of us has spent 10,000 hours learning to make sense of people and groups by the time we are ten. Social argues that our need to reach out to and connect with others is a primary driver behind our behavior. We believe that pain and pleasure alone guide our actions. Yet, new research using fMRI--including a great deal of original research conducted by Lieberman and his UCLA lab--shows that our brains react to social pain and pleasure in much the same way as they do to physical pain and pleasure. Fortunately, the brain has evolved sophisticated mechanisms for securing our place in the social world. We have a unique ability to read other people’s minds, to figure out their hopes, fears, and motivations, allowing us to effectively coordinate our lives with one another. And our most private sense of who we are is intimately linked to the important people and groups in our lives. This wiring often leads us to restrain our selfish impulses for the greater good. These mechanisms lead to behavior that might seem irrational, but is really just the result of our deep social wiring and necessary for our success as a species. Based on the latest cutting edge research, the findings in Social have important real-world implications. Our schools and businesses, for example, attempt to minimalize social distractions. But this is exactly the wrong thing to do to encourage engagement and learning, and literally shuts down the social brain, leaving powerful neuro-cognitive resources untapped. The insights revealed in this pioneering book suggest ways to improve learning in schools, make the workplace more productive, and improve our overall well-being.

"Unlike any other study in its field, The Altruistic Brain synthesizes into one theory the most important research into how and why - by purely physical mechanisms - humans empathize with one another and respond altruistically."--Jacket.

Consciousness is our gateway to experience: it enables us to recognize Van Gogh’s starry skies, be enraptured by Beethoven’s Fifth, and stand in awe of a snowcapped mountain. Yet consciousness is subjective, personal, and famously difficult to examine: philosophers have for centuries declared this mental entity so mysterious as to be impenetrable to science. In The Ravenous Brain, neuroscientist Daniel Bor departs sharply from this historical view, and builds on the latest research to propose a new model for how consciousness works. Bor argues that this brain-based faculty evolved as an accelerated knowledge gathering tool. Consciousness is effectively an idea factory—that choice mental space dedicated to innovation, a key component of which is the discovery of deep structures within the contents of our awareness. This model explains our brains’ ravenous appetite for information—and in particular, its constant search for patterns. Why, for instance, after all our physical needs have been met, do we recreationally solve crossword or Sudoku puzzles? Such behavior may appear biologically wasteful, but, according to Bor, this search for structure can yield immense evolutionary benefits—it led our ancestors to discover fire and farming, pushed modern society to forge ahead in science and technology, and guides each one of us to understand and control the world around us. But the sheer innovative power of human consciousness carries with it the heavy cost of mental fragility. Bor discusses the medical implications of his theory of consciousness, and what it means for the origins and treatment of psychiatric ailments, including attention-deficit disorder, schizophrenia, manic depression, and autism. All mental illnesses, he argues, can be reformulated as disorders of consciousness—a perspective that opens up new avenues of treatment for alleviating mental suffering. A controversial view of consciousness, The Ravenous Brain links cognition to creativity in an ingenious solution to one of science’s biggest mysteries.
