Calculated risks : how to know when numbers deceive you by Gerd Gigerenzer( Book )

29 editions published between 2002 and 2015 in 3 languages and held by 1,868 WorldCat member libraries worldwide

Gigerenzer explains that a major obstacle to our understanding of numbers is that we live with an illusion of certainty. Many of us believe that HIV tests, DNA fingerprinting, and the growing number of genetic tests are absolutely certain. But even DNA evidence can produce spurious matches. We cling to our illusion of certainty because the medical industry, insurance companies, investment advisers, and election campaigns have become purveyors of certainty, marketing it like a commodity. To avoid confusion, says Gigerenzer, we should rely on more understandable representations of risk, such as absolute risks. For example, it is said that a mammography screening reduces the risk of breast cancer by 25 percent. But in absolute risks, that means that out of every 1,000 women who do not participate in screening, 4 will die while out of 1,000 women who do, 3 will die. A 25 percent risk reduction sounds much more significant than a benefit that 1 out of 1,000 women will reap. This eye-opening book explains how we can overcome our ignorance of numbers and better understand the risks we may be taking with our money, our health, and our lives
Gut feelings : the intelligence of the unconscious by Gerd Gigerenzer( Book )

33 editions published between 2007 and 2014 in 3 languages and held by 1,731 WorldCat member libraries worldwide

Gigerenzer is one of the researchers of behavioral intuition responsible for the science behind Malcolm Gladwell's bestseller Blink. Gladwell showed how snap decisions often yield better results than careful analysis. Now, Gigerenzer explains why intuition is such a powerful decision-making tool. Drawing on a decade of research, Gigerenzer demonstrates that gut feelings are actually the result of unconscious mental processes--processes that apply rules of thumb that we've derived from our environment and prior experiences. The value of these rules lies precisely in their difference from rational analysis--they take into account only the most useful bits of information rather than attempting to evaluate all possible factors. By examining various decisions we make, Gigerenzer shows how gut feelings not only lead to good practical decisions, but also underlie the moral choices that make our society function.--From publisher description
The Empire of chance : how probability changed science and everyday life by Gerd Gigerenzer( Book )

39 editions published between 1989 and 2000 in English and Undetermined and held by 893 WorldCat member libraries worldwide

This book tells how quantitative ideas of chance have transformed the natural and social sciences as well as everyday life over the past three centuries. A continuous narrative connects the earliest application of probability and statistics in gambling and insurance to the most recent forays into law, medicine, polling, and baseball. Separate chapters explore the theoretical and methodological impact on biology, physics, and psychology. In contrast to the literature on the mathematical development of probability and statistics, this book centers on how these technical innovations recreated our conceptions of nature, mind, and society
Risk savvy : how to make good decisions by Gerd Gigerenzer( Book )

27 editions published between 2013 and 2016 in 5 languages and held by 753 WorldCat member libraries worldwide

"An eye-opening look at the ways we misjudge risk every day and a guide to making better decisions with our money, health, and personal lives. In the age of Big Data we often believe that our predictions about the future are better than ever before. But as risk expert Gerd Gigerenzer shows, the surprising truth is that in the real world, we often get better results by using simple rules and considering less information. In Risk Savvy, Gigerenzer reveals that most of us, including doctors, lawyers, financial advisers, and elected officials, misunderstand statistics much more often than we think, leaving us not only misinformed, but vulnerable to exploitation. Yet there is hope. Anyone can learn to make better decisions for their health, finances, family, and business without needing to consult an expert or a super computer, and Gigerenzer shows us how. Risk Savvy is an insightful and easy-to-understand remedy to our collective information overload and an essential guide to making smart, confident decisions in the face of uncertainty"--
Simple heuristics that make us smart by Gerd Gigerenzer( Book )

28 editions published between 1999 and 2002 in English and Chinese and held by 696 WorldCat member libraries worldwide

Fast and frugal heuristics - simple rules for making decisions with realistic mental resources - are presented here. Developing computational models of heuristics shows how fast and frugal heuristics can yield adaptive decisions
Bounded rationality : the adaptive toolbox by Reinhard Selten( Book )

28 editions published between 2001 and 2002 in English and Undetermined and held by 567 WorldCat member libraries worldwide

In a complex and uncertain world, humans and animals make decisions under the constraints of limited knowledge, resources, and time. Yet models of rational decision making in economics, cognitive science, biology, and other fields largely ignore these real constraints and instead assume agents with perfect information and unlimited time. About forty years ago, this view was challenged with the notion of "bounded rationality." Today, bounded rationality has become a fashionable term used for disparate views of reasoning. This book promotes bounded rationality as the key to understanding how real people make decisions. Using the concept of an "adaptive toolbox," a repertoire of fast and frugal rules for decision making under uncertainty, it attempts to impose more order and coherence on the idea of bounded rationality. The contributors view bounded rationality neither as optimization under constraints nor as the study of people's reasoning fallacies. The strategies in the adaptive toolbox dispense with optimization and, for the most part, with calculations of probabilities and utilities. The book extends the concept of bounded rationality from cognitive tools to emotions; it analyzes social norms, imitation, and other cultural tools as rational strategies; and it shows how smart heuristics can exploit the structure of environments
Adaptive thinking : rationality in the real world by Gerd Gigerenzer( Book )

35 editions published between 2000 and 2011 in English and held by 500 WorldCat member libraries worldwide

"Where do new ideas come from? What is social intelligence? How can innumeracy be turned into insight? Why do social scientists perform mindless statistical rituals? This new book addresses these questions as it attempts to rethink rationality as adaptive thinking: to understand how minds cope with their environments, both ecological and social. Together, these collected papers develop the idea that human thinking - from scientific creativity to simply understanding what a positive HIV test means - "happens" partly outside the mind." "Gerd Gigerenzer proposes and illustrates a bold new research program that investigates the psychology of rationality. Gigerenzer's original concepts of ecological, bounded, and social rationality provide an alternative framework to the study of human rationality. His path-breaking collection takes research on thinking, social intelligence, creativity, and decisionmaking out of an ethereal world - where the laws of logic and probability reign - and places it into the real world of human tools, heuristics, and social motives." "Adaptive Thinking is 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."--Jacket
Rationality for mortals : how people cope with uncertainty by Gerd Gigerenzer( Book )

20 editions published between 2008 and 2010 in English and held by 452 WorldCat member libraries worldwide

Gerd Gigerenzer's work examines the rationality of individuals not from the perspective of logic or probability, but from the point of view of adaptation to the real world of human behaviour and interaction with the environment. Seen from this perspective, human behaviour is more rational than it might otherwise appear

Reckoning with risk : learning to live with uncertainty by Gerd Gigerenzer( Book )

12 editions published between 2002 and 2003 in English and held by 239 WorldCat member libraries worldwide

However much we crave certainty, we live in an uncertain world. But are we guilty of wildly exaggerating the chances of some unwanted event happening to us? Are ordinary people idiots when reasoning with risk? Far too many of us, argues Gerd Gigerenzer, are hampered by our own innumeracy. Here, he shows us that our difficulties in thinking about numbers can easily be overcome
Bauchentscheidungen : die Intelligenz des Unbewussten und die Macht der Intuition by Gerd Gigerenzer( Book )

8 editions published between 2007 and 2015 in German and held by 205 WorldCat member libraries worldwide

'Das Herz hat seine Gründe, die der Verstand nicht kennt.' Viele Menschen treffen Entscheidungen 'aus dem Bauch heraus', was auf den ersten Blick aller Vernunft zu widersprechen scheint. Gerd Gigerenzer, Professor für Psychologie und Direktor am Berliner Max-Planck-Institut für Bildungsforschung, erkundet anhand zahlreicher Beispiele, woher unsere Bauchgefühle oder Intuitionen kommen und welcher spezifischen Logik unsere unbewusste Intelligenz folgt. Das Geheimnis des gefilterten Wissens - Ausgezeichnet als 'Wissenschaftsbuch des Jahres 2007'. Der Bestseller von Gerd Gigerenzer, einem der profiliertesten deutschen Psychologen der Gegenwart. Gerd Gigerenzer ist der in Wissenschaftskreisen derzeit meistzitierte deutsche Psychologe. Nach Lehrtätigkeiten in Konstanz, Salzburg und Chicago ist er heute Direktor am Max-Planck-Institut für Bildungsforschung in Berlin, wo er den Bereich 'Adaptives Verhalten und Kognition' leitet. Dort erforscht er u. a. Risikoverhalten und -kommunikation, die Natur sozialer Intelligenz und schliesslich, wie Menschen mit begrenzter Zeit und begrenztem Wissen Entscheidungen treffen. Seine Forschungsarbeit ist interdisziplinär und berührt die Fachrichtungen Ökonomie, Informatik, Psychologie, Mathematik, Anthropologie und Biologie. Er hat zahlreiche internationale Auszeichnungen erhalten, so auch den Preis der renommierten American Association for the Advancement of Science (AAAS). Sein populärwissenschaftliches Buch 'Das Einmaleins der Skepsis' (2002) fand international Beachtung
Heuristics : the foundations of adaptive behavior( Book )

21 editions published between 2010 and 2016 in English and held by 197 WorldCat member libraries worldwide

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
Ecological rationality : intelligence in the world by Peter M Todd( Book )

17 editions published between 2011 and 2012 in English and held by 189 WorldCat member libraries worldwide

"'More information is always better, and full information is best. More computation is always better, and optimization is best.' More-is-better ideals such as these have long shaped our vision of rationality. Yet humans and other animals typically rely on simple heuristics to solve adaptive problems, focusing on one or a few important cues and ignoring the rest, and shortcutting computation rather than striving for as much as possible. In this book, we argue that in an uncertain world, more information and computation are not always better, and we ask when, and why, less can be more. The answers to these questions constitute the idea of ecological rationality: how we are able to achieve intelligence in the world by using simple heuristics matched to the environments we face, exploiting the structures inherent in our physical, biological, social, and cultural surroundings."--Publisher's description
Better doctors, better patients, better decisions : envisioning health care 2020 by Gerd Gigerenzer( Book )

14 editions published between 2011 and 2016 in English and held by 169 WorldCat member libraries worldwide

"Contrary to popular opinion, one of the main problems in providing uniformly excellent health care is not lack of money but lack of knowledge - on the part of both doctors and patients. The studies in this book show that many doctors and most patients do not understand the available medical evidence. Both patients and doctors are 'risk illiterate' - frequently unable to tell the difference between actual risk and relative risk. Doctors often cannot interpret test results; patients cannot make informed decisions if they are given bad information. Surprisingly, treatments vary widely from one region to another. For example, in one referral region in Iowa, sixty percent of prostate patients had surgery, while in another region only fifteen percent had the same surgery. This unwarranted disparity in treatment decisions is the rule rather than the exception in the United States and Europe. All of this contributes to much wasted spending in health care
Experts in science and society by Elke Kurz-Milcke( Book )

13 editions published between 2003 and 2004 in English and held by 167 WorldCat member libraries worldwide

In today's complex world, we have come to rely increasingly on those who have expertise in specific areas and can bring their knowledge to bear on crucial social, political and scientific questions. Taking the viewpoint that experts are consulted when there is something important at stake for an individual, a group, or society at large, Experts in Science and Society explores expertise as a relational concept. How do experts balance their commitment to science with that to society? How does a society actually determine that a person has expertise? What personal traits are valued in an expert? From where does the expert derive authority? What makes new forms of expertise emerge? These and related questions are addressed from a wide range of areas in order to be inclusive, as well as to demonstrate similarities across areas. Likewise, in order to be culturally comparative, this volume includes examples and discussions of experts in different countries and even in different time periods. The topics include the roles of political experts, scientific experts, medical experts, legal experts, and more

Warum dick nicht doof macht und Genmais nicht tötet Über Risiken und Nebenwirkungen der Unstatistik by Thomas Bauer( Book )

7 editions published between 2014 and 2016 in German and held by 88 WorldCat member libraries worldwide

Durchblick in einer Welt voller Unstatistiken Trockenobst ist giftig, Fast Food macht depressiv, Choleragefahr nimmt rasant zu, Polen sind fleißiger als Deutsche: Mit solch dramatischen Meldungen auf höchst fragwürdiger Datenbasis lassen wir uns täglich nur allzu gern aufstören. Der Psychologe Gerd Gigerenzer, der Ökonom Thomas Bauer und der Statistiker Walter Krämer diagnostizieren uns eine Art Analphabetismus im Umgang mit Wahrscheinlichkeiten und Risiken und haben darauf mit der Ernennung der "Unstatistik des Monats" ( reagiert. Anhand haarsträubender Beispiele aus dem Reich der Statistik erklären sie, wie wir Humbug durchschauen, zwischen echter Information und Panikmache unterscheiden und die Welt wieder sehen, wie sie tatsächlich ist
Simply rational : decision making in the real world by Gerd Gigerenzer( Book )

6 editions published in 2015 in English and held by 58 WorldCat member libraries worldwide

Statistical illiteracy can have an enormously negative impact on decision making. This book brings together applied and theoretical research on risks and decision making across the fields of medicine, psychology, and economics. Collectively, the chapters demonstrate why the frame in which statistics are communicated is essential for broader understanding and sound decision making, and that understanding risks and uncertainty has wide-reaching implications for daily life
