New insights from the science of science Facts change all the time. Smoking has gone from doctor recommended to deadly. We used to think the Earth was the center of the universe and that the brontosaurus was a real dinosaur. In short, what we know about the world is constantly changing. Samuel Arbesman shows us how knowledge in most fields evolves systematically and predictably, and how this evolution unfolds in a fascinating way that can have a powerful impact on our lives. He takes us through a wide variety of fields, including those that change quickly, over the course of a few years, or over the span of centuries.

Traditionally, the concept of quality of life has been viewed through objective indicators. Beyond Facts looks at quality of life through a new lens, namely, the perceptions of millions of Latin Americans. Using an enhanced version of the recently created Gallup World Poll that incorporates Latin America-specific questions, the Inter-American Development Bank surveyed people from throughout the region and found that perceptions of quality of life are often very different from the reality. These surprising findings have enormous significance for the political economy of the region and provide a wealth of information for policymakers and development practitioners to feast upon.

It is widely acknowledged that a central aim of science is to achieve understanding of the world around us, and that possessing such understanding is highly important in our present-day society. But what does it mean to achieve this understanding? What precisely is scientific understanding? These are philosophical questions that have not yet received satisfactory answers. While there has been an ongoing debate about the nature of scientific explanation since Carl Hempel advanced his covering-law model in 1948, the related notion of understanding has been largely neglected, because most philosophers regarded understanding as merely a subjective by-product of objective explanations. By contrast, this book puts scientific understanding center stage. It is primarily a philosophical study, but also contains detailed historical case studies of scientific practice. In contrast to most existing studies in this area, it takes into account scientists' views and analyzes their role in scientific debate and development. The aim of Understanding Scientific Understanding is to develop and defend a philosophical theory of scientific understanding that can describe and explain the historical variation of criteria for understanding actually employed by scientists. The theory does justice to the insights of such famous physicists as Werner Heisenberg and Richard Feynman, while bringing much-needed conceptual rigor to their intuitions. The scope of the proposed account of understanding is the natural sciences: while the detailed case studies derive from physics, examples from other sciences are presented to illustrate its wider validity.

Many deny that racism remains pervasive in America today. How can we open eyes to the continuing disadvantages that keep many people of color from fulfilling their potential, and having an equal chance to achieve the “American Dream”?By presenting the impact of racism on the most innocent and powerless members of society– children of color – in the form of statistics, this book aims to change attitudes and perceptions. Children have no say about where they are born or what school they attend. They have no control over whether or not they get medical treatment when they fall ill. They can’t avoid exposure if their home is in a community blighted by pollution. The questions this book poses are: What responsibility do we expect children to take for their life circumstances? Do those conditions blight their futures? If they aren’t responsible, who is? Are some in society privileged and complicit in denying people of color the advantages and protections from harm most of us take for granted? Through the cumulative effect of official statistics rather than the more usual reliance on anecdote – by taking a “show me the numbers!” approach – this book will open minds, start conversations, and even prompt readers to take action. While the numbers are official they are often hard to find because they are scattered across so many sources. Art Munin has not only done the research, but shows the reader how to locate data on racial and socio-economic disparities, and develop her or his own case or classroom project.Color by Number takes as its metaphorical point of departure the familiar children’s activity of that name. Art Munin has painstakingly researched and gathered the numbers, and has filled in the spaces to reveal the hidden picture of racism in America from the perspectives of health, the environment, the law, and education.This book is intended as a fact-based, antiracism text for diversity and social justice courses, and as a resource for diversity and social justice educators as they craft their race, racism, and White privilege curricula. Art Munin’s multidisciplinary approach – drawing on scholarly work from medicine, law, sociology, psychology, and education – provides the reader with a comprehensive way to understand the pervasiveness of racism.

How biases, the desire for a good narrative, reliance on citation metrics, and other problems undermine confidence in modern science. Modern science is built on experimental evidence, yet scientists are often very selective in deciding what evidence to use and tend to disagree about how to interpret it. In The Matter of Facts, Gareth and Rhodri Leng explore how scientists produce and use evidence. They do so to contextualize an array of problems confronting modern science that have raised concerns about its reliability: the widespread use of inappropriate statistical tests, a shortage of replication studies, and a bias in both publishing and citing “positive” results. Before these problems can be addressed meaningfully, the authors argue, we must understand what makes science work and what leads it astray. The myth of science is that scientists constantly challenge their own thinking. But in reality, all scientists are in the business of persuading other scientists of the importance of their own ideas, and they do so by combining reason with rhetoric. Often, they look for evidence that will support their ideas, not for evidence that might contradict them; often, they present evidence in a way that makes it appear to be supportive; and often, they ignore inconvenient evidence. In a series of essays focusing on controversies, disputes, and discoveries, the authors vividly portray science as a human activity, driven by passion as well as by reason. By analyzing the fluidity of scientific concepts and the dynamic and unpredictable development of scientific fields, the authors paint a picture of modern science and the pressures it faces.

Draws a history of journalism's most respected tenet—objectivity If American journalism were a religion, as it has been called, then its supreme deity would be "objectivity." The high priests of the profession worship the concept, while the iconoclasts of advocacy journalism, new journalism, and cyberjournalism consider objectivity a golden calf. Meanwhile, a groundswell of tabloids and talk shows and the increasing infringement of market concerns make a renewed discussion of the validity, possibility, and aim of objectivity a crucial pursuit. Despite its position as the orbital sun of journalistic ethics, objectivity—until now—has had no historian. David T. Z. Mindich reaches back to the nineteenth century to recover the lost history and meaning of this central tenet of American journalism. His book draws on high profile cases, showing the degree to which journalism and its evolving commitment to objectivity altered–and in some cases limited—the public's understanding of events and issues. Mindich devotes each chapter to a particular component of this ethic–detachment, nonpartisanship, the inverted pyramid style, facticity, and balance. Through this combination of history and cultural criticism, Mindich provides a profound meditation on the structure, promise, and limits of objectivity in the age of cybermedia.
