This book is a reaction to popular assumptions that innovation is always a force for good. While the popular press and politicians often take the view that "the more innovation, the better", the chapters in this edited volume reflect on the harmful effects of innovation on society and the environment. The book begins with a broad discussion of the dark side of innovation, followed by contributions by various experts in the area. It is a critical reply to the innovation optimists, complementing the list of indicators that show steady human progress with a list of indicators that show sustained deterioration (largely due to innovation). The volume outlines some relevant dimensions of harmful innovation, before distinguishing between the types of harm brought on by innovation. The various contributed chapters focus on the following themes: a bibliometric analysis of the scientific literature on the harmful consequences of innovation; harmful side-effects from solar photovoltaic waste; harmful consequences of process innovations on working practices in areas such as accountancy; the difficulties of transferring innovations from research to practice in clinical healthcare; and the harmful consequences of social innovations. The chapters in this book were originally published as a special issue of the journal Industry and Innovation.
