Negative Capability? Measuring the Unmeasurable in Education

This introductory article to the special issue of "Comparative Education" on measuring the unmeasurable in education considers measurement as reflecting facts and uncertainties. The notion of negative capability is used metaphorically to depict some limits of what is measurable, and portray aspects of the process of education, associated with uncertainty and public scrutiny of complexity. Four overarching questions--what, when, why and how--have guided the reflections of the authors who have contributed to the special issue. "What" are we measuring when we try to measure the unmeasurable in education and what are we not measuring? "When" have attempts been made to measure the unmeasurable in education, what metrics have been adopted in which contexts, and with what outcomes? "Why" have measures been adopted as indicators of the unmeasurable, such as human rights? "How" have particular historically located organisations approached the problem of measuring the apparently unmeasurable in education, with what epistemological, normative and conceptual resources, and consequences? The introductory article looks at measurement as a form of negative capability in some discussions of history of social statistics in education, the current debate over indicators for the Sustainable Development Goals, and how to measure gender equality in education.
