Governing Misinformation in Everyday Knowledge Commons delves into the complex issue of misinformation in our daily lives. The book synthesizes three scholarly traditions - everyday life, misinformation, and governing knowledge commons - to present 10 case studies of online and offline communities tackling diverse dilemmas regarding truth and information quality. The book highlights how communities manage issues of credibility, trust, and information quality continuously, to mitigate the impact of misinformation when possible. It also explores how social norms and intentional governance evolve to distinguish between problematic disinformation and little white lies. Through a coproduction of governance and (mis-)information, the book raises a set of ethical, economic, political, social, and technological questions that require systematic study and careful deliberation. This title is also available as Open Access on Cambridge Core. This volume explores how people experience, produce, and manage misinformation in their everyday lives. Madelyn Rose R.
