Measure development and the hermeneutic task

Abstract

I examine the dynamics of measure development using two case studies: temperature, and health-related quality of life. I argue, following Bas van Fraassen and Leah McClimans that in each case these dynamics have a hermeneutic structure. Measure development is plagued by epistemic circularity, as is the task of interpreting a text, and similar strategies can be used in both measure development and hermeneutics to overcome that circularity. I show that Hans Georg Gadamer’s philosophical hermeneutics in particular are an effective lens through which to examine the development of the temperature standard as described by Hasok Chang. Despite similar grounding in hermeneutics, I note an important difference between measure development for temperature and for health-related quality of life. Namely, while the meaning of temperature can be standardized, the meaning of health-related quality of life cannot. This standardization of meaning for the temperature concept represents a limit to the analogy with hermeneutics. Finally, I argue that the indeterminacy we find in health-related quality of life measurement is a result not only of analogy with the hermeneutic task, but of full-fledged participation in it.
