Rationality For Mortals

What is the nature of human wisdom? For many, the ideal image of sapiens is a heavenly one: an omniscient God, a Laplacean demon, a supercomputer, or a fully consistent logical system. Gerd Gigerenzer argues, in contrast, that there are more efficient tools than logic in our minds, which he calls fast and frugal heuristics. These adaptive tools work in a world where the present is only partially known and the future is uncertain. Here, rationality is not logical but ecological, and this volume shows how this insight can help remedy even the widespread problem of statistical innumeracy.RATIONALITY FOR MORTALS (which follows on a previous collection, ADAPTIVE THINKING, also published by OUP) presents Gigerenzer's most recent articles, revised and updated where appropriate, together with a newly written introduction.

This volume collects Gigerenzer's recent articles on the psychology of rationality. This volume should appeal, like the earlier volumes, to a broad mixture of cognitive psychologists, philosophers, economists, and others who study decision making.

Where do new ideas come from? What is social intelligence? Why do social scientists perform mindless statistical rituals? This vital book is about rethinking rationality as adaptive thinking: to understand how minds cope with their environments, both ecological and social.Gerd Gigerenzer proposes and illustrates a bold new research program that investigates the psychology of rationality, introducing the concepts of ecological, bounded, and social rationality. His path-breaking collection takes research on thinking, social intelligence, creativity, and decision-making out of an ethereal world where the laws of logic and probability reign, and places it into our real world of human behavior and interaction. Adaptive Thinking is accessibly written for general readers with an interest in psychology, cognitive science, economics, sociology, philosophy, artificial intelligence, and animal behavior. It also teaches a practical audience, such as physicians, AIDS counselors, and experts in criminal law, how to understand and communicate uncertainties and risks.

Simple Heuristics That Make Us Smart invites readers to embark on a new journey into a land of rationality that differs from the familiar territory of cognitive science and economics. Traditional views of rationality tend to see decision makers as possessing superhuman powers of reason, limitless knowledge, and all of eternity in which to ponder choices. To understand decisions in the real world, we need a different, more psychologically plausible notion of rationality, and this book provides it. It is about fast and frugal heuristics--simple rules for making decisions when time is pressing and deep thought an unaffordable luxury. These heuristics can enable both living organisms and artificial systems to make smart choices, classifications, and predictions by employing bounded rationality. But when and how can such fast and frugal heuristics work? Can judgments based simply on one good reason be as accurate as those based on many reasons? Could less knowledge even lead to systematically better predictions than more knowledge? Simple Heuristics explores these questions, developing computational models of heuristics and testing them through experiments and analyses. It shows how fast and frugal heuristics can produce adaptive decisions in situations as varied as choosing a mate, dividing resources among offspring, predicting high school drop out rates, and playing the stock market. As an interdisciplinary work that is both useful and engaging, this book will appeal to a wide audience. It is ideal for researchers in cognitive psychology, evolutionary psychology, and cognitive science, as well as in economics and artificial intelligence. It will also inspire anyone interested in simply making good decisions.

How do people make decisions when time is limited, information unreliable, and the future uncertain? Based on the work of Nobel laureate Herbert Simon and with the help of colleagues around the world, the Adaptive Behavior and Cognition (ABC) Group at the Max Planck Institute for Human Development in Berlin has developed a research program on simple heuristics, also known as fast and frugal heuristics. In the social sciences, heuristics have been believed to be generally inferior to complex methods for inference, or even irrational. Although this may be true in "small worlds" where everything is known for certain, we show that in the actual world in which we live, full of uncertainties and surprises, heuristics are indispensable and often more accurate than complex methods. Contrary to a deeply entrenched belief, complex problems do not necessitate complex computations. Less can be more. Simple heuristics exploit the information structure of the environment, and thus embody ecological rather than logical rationality. Simon (1999) applauded this new program as a "revolution in cognitive science, striking a great blow for sanity in the approach to human rationality." By providing a fresh look at how the mind works as well as the nature of rationality, the simple heuristics program has stimulated a large body of research, led to fascinating applications in diverse fields from law to medicine to business to sports, and instigated controversial debates in psychology, philosophy, and economics. In a single volume, the present reader compiles key articles that have been published in journals across many disciplines. These articles present theory, real-world applications, and a sample of the large number of existing experimental studies that provide evidence for people's adaptive use of heuristics.

NAMED A BEST BOOK OF THE YEAR BY ESQUIRE, THE IRISH TIMES AND THE TIMES LITERARY SUPPLEMENT A provocative history of men who were worshipped as gods that illuminates the connection between power and religion and the role of divinity in a secular age Ever since 1492, when Christopher Columbus made landfall in the New World and was hailed as a heavenly being, the accidental god has haunted the modern age. From Haile Selassie, acclaimed as the Living God in Jamaica, to Britain’s Prince Philip, who became the unlikely center of a new religion on a South Pacific island, men made divine—always men—have appeared on every continent. And because these deifications always emerge at moments of turbulence—civil wars, imperial conquest, revolutions—they have much to teach us. In a revelatory history spanning five centuries, a cast of surprising deities helps to shed light on the thorny questions of how our modern concept of “religion” was invented; why religion and politics are perpetually entangled in our supposedly secular age; and how the power to call someone divine has been used and abused by both oppressors and the oppressed. From nationalist uprisings in India to Nigerien spirit possession cults, Anna Della Subin explores how deification has been a means of defiance for colonized peoples. Conversely, we see how Columbus, Cortés, and other white explorers amplified stories of their godhood to justify their dominion over native peoples, setting into motion the currents of racism and exclusion that have plagued the New World ever since they touched its shores. At once deeply learned and delightfully antic, Accidental Gods offers an unusual keyhole through which to observe the creation of our modern world. It is that rare thing: a lyrical, entertaining work of ideas, one that marks the debut of a remarkable literary career.

"Zade Holder has always been a free-spirited young woman, from a long dynasty of tarot-card readers, fortunetellers, and practitioners of magick. Growing up in a small town and never quite fitting in, Zade is determined to forge her own path. She leaves her home in Tennessee to break free from her overprotective mother Dela, the local resident spellcaster and fortuneteller. Zade travels to Las Vegas and uses supernatural powers to become part of a premiere magic show led by the infamous magician Charles Spellman. Zade fits right in with his troupe of artists and misfits. After all, when everyone is slightly eccentric, appearing 'normal' is much less important. Behind the scenes of this multimillion-dollar production, Zade finds herself caught in a love triangle with Mac, the show's good-looking but rough-around-the-edges technical director and Jackson, the tall, dark, handsome and charming bandleader. Zade's secrets and the struggle to choose between Mac or Jackson creates reckless tension during the grand finale of the show. Using Chaos magick, which is known for being unpredictable, she tests her abilities as a spellcaster farther than she's ever tried and finds herself at death's door. Her fate is left in the hands of a mortal who does not believe in a world of real magick, a fortuneteller who knew one day Zade would put herself in danger and a dagger with mystical powers"--Amazon.com
