This book contributes to the study of science and politics by shedding light on sometimes dark, hidden or ignored aspects of openness as a core policy agenda. While opening up of science to public scrutiny and public deliberation is good in principle, various dilemmas and problems are entailed by this move, which also should be made public and be discussed more openly. Developed as a solution to perceived crises in science/society relations, openness and transparency initiatives might hide ‘monsters’ that need to be made visible and need to be examined. Chapters in this book deal with four themes: transparency in the context of science in the public sphere; responsibility in the context of in contemporary research practice and governance, both globally and locally; experts in the context of policy-making, risk assessment and the regulation of science; and faith in the context of tensions and misunderstandings between science and religion. Each section of the book contains an opening essay by experts on a particular theme (Mark Brown, Benjamin Worthy, Barbara Prainsack/Sabina Leonelli, Chris Toumey). The book closes with an epilogue by Stephen Turner and an essay by John Holmwood. At present, openness in science is more important than ever. This book should be of interest to academics and members of the public who want to know more about the challenges and opportunities of 'making science public' - the theme of a Leverhulme Trust funded research programme on which this book is based.
