The process of technological change takes a wide variety of forms. Propositions that may be accurate when referring to the pharmaceutical industry may be totally inappropriate when applied to the aircraft industry or to computers or forest products. The central theme of Nathan Rosenberg's new book is the idea that technological changes are often 'path dependent', in the sense that their form and direction tend to be influenced strongly by the particular sequence of earlier events out of which a new technology has emerged. The book advances the understanding of technological change by explictly recognising its essential diversity and path-dependent nature. Individual chapters explore the particular features of new technologies in different historical and sectoral contexts. This book presents a unique account of how technological change is generated and the processes by which improved technologies are introduced.

Nobody wants to fail. But in highly complex organizations, success can happen only when we confront our mistakes, learn from our own version of a black box, and create a climate where it’s safe to fail. We all have to endure failure from time to time, whether it’s underperforming at a job interview, flunking an exam, or losing a pickup basketball game. But for people working in safety-critical industries, getting it wrong can have deadly consequences. Consider the shocking fact that preventable medical error is the third-biggest killer in the United States, causing more than 400,000 deaths every year. More people die from mistakes made by doctors and hospitals than from traffic accidents. And most of those mistakes are never made public, because of malpractice settlements with nondisclosure clauses. For a dramatically different approach to failure, look at aviation. Every passenger aircraft in the world is equipped with an almost indestructible black box. Whenever there’s any sort of mishap, major or minor, the box is opened, the data is analyzed, and experts figure out exactly what went wrong. Then the facts are published and procedures are changed, so that the same mistakes won’t happen again. By applying this method in recent decades, the industry has created an astonishingly good safety record. Few of us put lives at risk in our daily work as surgeons and pilots do, but we all have a strong interest in avoiding predictable and preventable errors. So why don’t we all embrace the aviation approach to failure rather than the health-care approach? As Matthew Syed shows in this eye-opening book, the answer is rooted in human psychology and organizational culture. Syed argues that the most important determinant of success in any field is an acknowledgment of failure and a willingness to engage with it. Yet most of us are stuck in a relationship with failure that impedes progress, halts innovation, and damages our careers and personal lives. We rarely acknowledge or learn from failure—even though we often claim the opposite. We think we have 20/20 hindsight, but our vision is usually fuzzy. Syed draws on a wide range of sources—from anthropology and psychology to history and complexity theory—to explore the subtle but predictable patterns of human error and our defensive responses to error. He also shares fascinating stories of individuals and organizations that have successfully embraced a black box approach to improvement, such as David Beckham, the Mercedes F1 team, and Dropbox.

The Black Box is not a tale of a great man. This story is about someone like you: a human being endeavoring to make tomorrow better than today. Each chapter recounts a formative experience and concludes with a 'Black Box': an explanation of how a given situation helped me develop the mindset required to thrive in that type of environment.An airplane's black box records all circumstantial things occurring around and within the aircraft, as well as the voices (and radio transmissions) in the head of the airliner. When an airplane crashes engineers look into the black box to study what went wrong. However, black boxes also have stories of success, but we rarely look to them for those narratives. Memories, like a black box, are nearly permanent records. Black boxes are stored in reinforced shells designed to survive 30 minutes in 2000-degree Fahrenheit heat as well as submersion in 20,000 feet deep water.Your black box is filled with helpful memories, but so often you fail to look into your black box to pull wisdom from it. Sometimes we do not want to open the black box and look in because it means seeing our hardships replayed, seeing things that cause us fear and pain. As you peer into my black box, it will inspires you to look into your own. Our black boxes are filled with explanations of why we crash as well as stories of how we have soared above turbulence.Most of these chapters have been developed as self encapsulated stories from which a moral can be drawn without reference to previous chapters. I share the story of my life knowing that my achievements outstrip those of the average person by only a modest margin. The validity of this work lies in the distance between my starting point and where I stand today. This book is about you. It should drive you to consult your black box as you adventure through life, and to use the experience, strength and resolve that you already have to make your journey easier and more enjoyable.

'Close your eyes and slowly count backward from ten.' America, the near future. A young spy on a mission logs her observations. The result is an intense thriller, and a minute dissection of the experience of a woman whose beauty is also her camouflage, for whom control relies on submission: a woman whose success - whose life - depends on being seen and not seen. Originally published online via Twitter by @NYerFiction, Jennifer Egan's first new fiction since the phenomenal success of A Visit From the Goon Squad is a taut, compulsive work of unrelenting genius.

Every day, corporations are connecting the dots about our personal behavior—silently scrutinizing clues left behind by our work habits and Internet use. The data compiled and portraits created are incredibly detailed, to the point of being invasive. But who connects the dots about what firms are doing with this information? The Black Box Society argues that we all need to be able to do so—and to set limits on how big data affects our lives. Hidden algorithms can make (or ruin) reputations, decide the destiny of entrepreneurs, or even devastate an entire economy. Shrouded in secrecy and complexity, decisions at major Silicon Valley and Wall Street firms were long assumed to be neutral and technical. But leaks, whistleblowers, and legal disputes have shed new light on automated judgment. Self-serving and reckless behavior is surprisingly common, and easy to hide in code protected by legal and real secrecy. Even after billions of dollars of fines have been levied, underfunded regulators may have only scratched the surface of this troubling behavior. Frank Pasquale exposes how powerful interests abuse secrecy for profit and explains ways to rein them in. Demanding transparency is only the first step. An intelligible society would assure that key decisions of its most important firms are fair, nondiscriminatory, and open to criticism. Silicon Valley and Wall Street need to accept as much accountability as they impose on others.
