The role of experts and their expertise, in our personal and social lives, has taken centre stage in the debates about our post-COVID-19 world. Scientific disinformation is rife, and expertise is badly needed to tackle highly complex social problems. This book brings together philosophers, sociologists and policy experts to discuss the nature, scope and limitations of expert advice in policy decisions. The chapters collected here address some of the most fundamental questions in the debate on the role of experts. They explore, among others, the definitions of expertise, the role of experts in modern democracies, the dilemma of choosing between equally competent and qualified experts who cannot agree, the objectivity of expert judgements, the relationship between experts and novices in polarised social settings and the conditions on the trustworthiness of experts. These explorations, by some of the best- known academics working in the field, highlight the complexities of the questions they address but also lay down a road map for addressing them. The chapters in this book were originally published in Social Epistemology: A Journal of Knowledge, Culture and Policy.

What does it mean to be an expert? In Rethinking Expertise, Harry Collins and Robert Evans offer a radical new perspective on the role of expertise in the practice of science and the public evaluation of technology. Collins and Evans present a Periodic Table of Expertises based on the idea of tacit knowledge—knowledge that we have but cannot explain. They then look at how some expertises are used to judge others, how laypeople judge between experts, and how credentials are used to evaluate them. Throughout, Collins and Evans ask an important question: how can the public make use of science and technology before there is consensus in the scientific community? This book has wide implications for public policy and for those who seek to understand science and benefit from it. “Starts to lay the groundwork for solving a critical problem—how to restore the force of technical scientific information in public controversies, without importing disguised political agendas.”—Nature “A rich and detailed ‘periodic table’ of expertise . . . full of case studies, anecdotes and intriguing experiments.”—Times Higher Education Supplement (UK)

Since its original publication, Expert Political Judgment by New York Times bestselling author Philip Tetlock has established itself as a contemporary classic in the literature on evaluating expert opinion. Tetlock first discusses arguments about whether the world is too complex for people to find the tools to understand political phenomena, let alone predict the future. He evaluates predictions from experts in different fields, comparing them to predictions by well-informed laity or those based on simple extrapolation from current trends. He goes on to analyze which styles of thinking are more successful in forecasting. Classifying thinking styles using Isaiah Berlin's prototypes of the fox and the hedgehog, Tetlock contends that the fox--the thinker who knows many little things, draws from an eclectic array of traditions, and is better able to improvise in response to changing events--is more successful in predicting the future than the hedgehog, who knows one big thing, toils devotedly within one tradition, and imposes formulaic solutions on ill-defined problems. He notes a perversely inverse relationship between the best scientific indicators of good judgement and the qualities that the media most prizes in pundits--the single-minded determination required to prevail in ideological combat. Clearly written and impeccably researched, the book fills a huge void in the literature on evaluating expert opinion. It will appeal across many academic disciplines as well as to corporations seeking to develop standards for judging expert decision-making. Now with a new preface in which Tetlock discusses the latest research in the field, the book explores what constitutes good judgment in predicting future events and looks at why experts are often wrong in their forecasts.

First released in the Spring of 1999, How People Learn has been expanded to show how the theories and insights from the original book can translate into actions and practice, now making a real connection between classroom activities and learning behavior. This edition includes far-reaching suggestions for research that could increase the impact that classroom teaching has on actual learning. Like the original edition, this book offers exciting new research about the mind and the brain that provides answers to a number of compelling questions. When do infants begin to learn? How do experts learn and how is this different from non-experts? What can teachers and schools do-with curricula, classroom settings, and teaching methodsâ€"to help children learn most effectively? New evidence from many branches of science has significantly added to our understanding of what it means to know, from the neural processes that occur during learning to the influence of culture on what people see and absorb. How People Learn examines these findings and their implications for what we teach, how we teach it, and how we assess what our children learn. The book uses exemplary teaching to illustrate how approaches based on what we now know result in in-depth learning. This new knowledge calls into question concepts and practices firmly entrenched in our current education system. Topics include: How learning actually changes the physical structure of the brain. How existing knowledge affects what people notice and how they learn. What the thought processes of experts tell us about how to teach. The amazing learning potential of infants. The relationship of classroom learning and everyday settings of community and workplace. Learning needs and opportunities for teachers. A realistic look at the role of technology in education.

"In the early 1990s, a small group of "AIDS denialists," including a University of California professor named Peter Duesberg, argued against virtually the entire medical establishment's consensus that the human immunodeficiency virus (HIV) was the cause of Acquired Immune Deficiency Syndrome. Science thrives on such counterintuitive challenges, but there was no evidence for Duesberg's beliefs, which turned out to be baseless. Once researchers found HIV, doctors and public health officials were able to save countless lives through measures aimed at preventing its transmission"--
