At Science Progress, University of Sussex Ph.D. student Molly Morgan discusses ways to make science and technology policy debates more open and transparent. A key to successfully doing so is to encourage "broad deliberation," she writes, and suggests applying Multicriteria Mapping to these discussions. Developed by Andrew Stirling and others at the University of Sussex, MCM "is based on principles of deliberation, participatory public engagement, and the integration of both 'quantitative' and 'qualitative' approaches to policy appraisal."
