Advanced technologies and increasing automation have forever changed how systems work and how people interact with them. Transportation systems, energy extraction and production systems, medical devices, and manufacturing processes are increasingly complex. With the use of these complex systems comes increased potential for harm to humans, property, and the environment. System safety is a widely accepted management and engineering approach to analyze and address risks in these complex systems. When used correctly, system safety methods can provide tremendous benefits, focusing resources to reduce risk and improve safety. But poor system safety analyses can lead to overconfidence, and can result in a misunderstanding of the potential for harm. The System Safety Skeptic describes critical aspects of the discipline of system safety, including: Safety planning Hazard identification Hazard risk assessment and associated risk decision making Risk reduction and hazard controls Risk reduction verification Hazard tracking and anomaly reporting Safety management and culture Accidents in multiple industries and organizations are used to illustrate potential missteps in the system safety process, including: Failure to plan and implement systematic safety efforts, and failure to plan for emergencies Failure to accurately identify the hazards and what can go wrong Underestimating the chances that an accident could happen Underestimating the worst possible outcomes Overestimating the effectiveness of safeguards Failure to properly verify that safeguards actually work Failure to learn from the past Failure of the organization to adequately manage system safety efforts This book provides hundreds of lessons learned in safety management and engineering, drawing from examples from many industries as well as the author's years of experience in the field. These real-world lessons help foster a healthy skepticism toward safety analysis and management in order to prevent future accidents.

System safety is the application of engineering and management principles, criteria, and techniques to optimize safety within the constraints of operational effectiveness, time, and cost throughout all phases of the system life cycle. System safety is to safety as systems engineering is to engineering. When performing appropriate analysis, the evaluation is performed holistically by tying into systems engineering practices and ensuring that system safety has an integrated system-level perspective.The NASA System Safety Handbook presents the overall framework for System Safety and provides the general concepts needed to implement the framework. The treatment addresses activities throughout the system life cycle to assure that the system meets safety performance requirements and is as safe as reasonably practicable.This handbook is intended for project management and engineering teams and for those with review and oversight responsibilities. It can be used both in a forward-thinking mode to promote the development of safe systems, and in a retrospective mode to determine whether desired safety objectives have been achieved.The topics covered in this volume include general approaches for formulating a hierarchy of safety objectives, generating a corresponding hierarchical set of safety claims, characterizing the system safety activities needed to provide supporting evidence, and presenting a risk-informed safety case that validates the claims. Volume 2, to be completed in 2012, will provide specific guidance on the conduct of the major system safety activities and the development of the evidence.

System safety is a widely accepted management and engineering approach to analyze and address risks in complex systems in order to prevent accidents. Because software and computing systems are integral to most systems, software safety has become a critical component of an overall system safety effort. Software and System Safety discusses critical elements of the discipline of system safety and shows how software and computing systems fit in the system safety process. Software-specific aspects of the system safety process are addressed to show concerns common to complex systems. The many accidents and incidents presented in this book illustrate important lessons learned and show how software-related hazards can be misidentified, software risks can be improperly assessed, hazard controls may be misapplied, and software and system testing may not effectively verify that the risk had been reduced. The lessons learned come from a variety of industries and organizations, and include the author’s personal experience. The real-world lessons provided in this book can be used to improve existing software safety and system safety efforts, and can help when planning new system safety programs.

Fake news, pseudoscience, and quackery have become scourges, spreading through society from social media all the way to Congress. The line between entertainment and reality, between fact and fiction, has become blurred. Some of the most crucial issues of our time—climate change, vaccines, and genetically modified organisms—have become prime targets for nefarious disinformation campaigns. Far too many people have become distrustful of real science. Even those who still trust science no longer know what to believe or how to identify the truth. Not only does this result in the devaluation and distrust of real science, but it is also dangerous: people acting based on false information can hurt themselves or those around them. We must equip ourselves with the knowledge and skills to fight back against all this disinformation. InScience and the Skeptic: Discerning Fact from Fiction, you will learn how science is done, from the basic scientific method to the vetting process that scientific papers must go through to become published; how and why some people intentionally or unintentionally spread misinformation; and the dangers in believing and spreading false information. You'll also find twenty easy-to-follow rules for distinguishing fake science from the real deal. Armed with this book, empower yourself with knowledge, learning what information to trust and what to dismiss as deceit. "We're not just fighting an epidemic; we're fighting an infodemic. . . . This is a time for facts, not fear. This is a time for rationality, not rumors. This is a time for solidarity, not stigma."—Tedros Adhanom Ghebreyesus, director-general of the WHO "Our deepest beliefs should help navigate reality, not determine it."—Michael Gersen, The Washington Post "Journalism is very much about trying to simplify and distribute information about what's new and where advances have been made. That's incompatible with the scientific process, which can take a long time to build a body of evidence."—Kelly McBride, Poynter Institute

Highly recommended as a first philosophy book...-Library JournalThis lucid, informal, and very accessible history of Western thought takes the unique approach of interpreting skepticism-i.e., doubts about knowledge claims and the criteria for making such claims-as an important stimulus for the development of philosophy. The authors argue that practically every great thinker from the time of the Greeks to the present has produced theories designed to forestall or refute skepticism: from Plato to Moore and Wittgenstein. The influence of and responses to such 20th-century skeptics as Russell and Derrida are also discussed critically.Popkin and Stroll review each major theory of philosophy chronologically and then further organize these theories into their respective subject areas: metaphysics, epistemology, ethics, political philosophy, and philosophy of religion. Within each subject area the authors discuss how the skeptical challenge gave rise to new philosophical positions. The volume concludes with an especially interesting debate between the authors on the merits of skepticism today. Stroll thinks that ultimately the doubts expressed by skeptics can be refuted, while Popkin denies this.This is an outstanding introduction to the problems of philosophy by two eminent philosophers with a gift for presenting the history of ideas in a very enjoyable fashion.Richard Popkin (Los Angeles, CA) is professor emeritus of philosophy at Washington University, St. Louis, and adjunct professor of history and philosophy at the University of California at Los Angeles.Avrum Stroll (San Diego, CA) is research professor of philosophy at the University of California, San Diego.

Safety has traditionally been defined as a condition where the number of adverse outcomes was as low as possible (Safety-I). From a Safety-I perspective, the purpose of safety management is to make sure that the number of accidents and incidents is kept as low as possible, or as low as is reasonably practicable. This means that safety management must start from the manifestations of the absence of safety and that - paradoxically - safety is measured by counting the number of cases where it fails rather than by the number of cases where it succeeds. This unavoidably leads to a reactive approach based on responding to what goes wrong or what is identified as a risk - as something that could go wrong. Focusing on what goes right, rather than on what goes wrong, changes the definition of safety from ’avoiding that something goes wrong’ to ’ensuring that everything goes right’. More precisely, Safety-II is the ability to succeed under varying conditions, so that the number of intended and acceptable outcomes is as high as possible. From a Safety-II perspective, the purpose of safety management is to ensure that as much as possible goes right, in the sense that everyday work achieves its objectives. This means that safety is managed by what it achieves (successes, things that go right), and that likewise it is measured by counting the number of cases where things go right. In order to do this, safety management cannot only be reactive, it must also be proactive. But it must be proactive with regard to how actions succeed, to everyday acceptable performance, rather than with regard to how they can fail, as traditional risk analysis does. This book analyses and explains the principles behind both approaches and uses this to consider the past and future of safety management practices. The analysis makes use of common examples and cases from domains such as aviation, nuclear power production, process management and health care. The final chapters explain the theoret

The global health and fitness industry is worth an estimated $4 trillion. We spend $90 billion each year on health club memberships and $100 billion each year on dietary supplements. In such an industrial climate, lax regulations on the products we are sold (supplements, fad-diets, training programs, gadgets, and garments) result in marketing campaigns underpinned by strong claims and weak evidence. Moreover, our critical faculties are ill-suited to a culture characterized by fake news, social media, misinformation, and bad science. We have become walking, talking prey to 21st-Century Snake Oil salesmen. In The Skeptic’s Guide to Sports Science, Nicholas B. Tiller confronts the claims behind the products and the evidence behind the claims. The author discusses what might be wrong with the sales pitch, the glossy magazine advert, and the celebrity endorsements that our heuristically-wired brains find so innately attractive. Tiller also explores the appeal of the one quick fix, the fallacious arguments that are a mainstay of product advertising, and the critical steps we must take in retraining our minds to navigate the pitfalls of the modern consumerist culture. This informative and accessible volume pulls no punches in scrutinizing the plausibility of, and evidence for, the most popular sports products and practices on the market. Readers are encouraged to confront their conceptualizations of the industry and, by the book’s end, they will have acquired the skills necessary to independently judge the effectiveness of sports-related products. This treatise on the commercialization of science in sport and exercise is a must-read for exercisers, athletes, students, and practitioners who hope to retain their intellectual integrity in a lucrative health and fitness industry that is spiraling out-of-control.
