In this talk, I revisit the Quantified Self movement, a community of practice concerned with the use and development of self-tracking tools for the purpose of self-improvement and health management (see

I discuss the ways in which Quantified Self practices and their data driven approach can be considered as “personal science,” a term first introduced by Martin and Brouwer in early 1990s and recently adopted by the Quantified Self community to describe its self-tracking activities and objectives. In doing so, I revisit some relevant arguments put forward by the philosopher, Hans-Georg Gadamer, vis-à-vis the value of the personal and hermeneutic dimension to understanding aspects of health and appreciating the limits of traditional medical methods and their generalising approach. Drawing on relevant examples, I discuss how self-tracking can be seen, at once, as a way of reclaiming autonomy and control over one’s health and physical activity as well as a form of outsourcing decision-making to technology itself.

This discussion leads me to differentiate between active and passive self-tracking, and between members of the Quantified Self circle who build their own tools and the general users who rely on the commercial tech solutions available on the market. Ultimately, I suggest that the Quantified Self community can act as a “guru” for mainstream self-trackers by nurturing a critical and inclusive approach to technological development and use, which can enable users to be involved in the means of production and become experts rather than just users.
