Looking at yet another tweet and another post about the Quantified Self, I started reflecting this morning on the Silicon Valley-driven fascination with the quantification of one’s own activities, body and habits.

The Quantified Self movement is portrayed as the nec-plus-ultra of objectivity that will help us live a better life. But something big is missing, and Jenny Davis PhD, a sociologist who teaches at James Madison University, seeks to address the fundamental issue of “why”. She argues (in a March 2013 blog post) that the reasons why people quantify themselves are entirely qualitative, with all that this implies:

“Self-quantification has a really important, prevalent, and somewhat ironic, qualitative component. This qualitative component is key in mediating between raw numbers and identity meanings. If self-quantifiers are seeking self-knowledge through numbers, then narratives and subjective interpretations are the mechanisms by which data morphs into selves. Self-quantifiers don’t just use data to learn about themselves, but rather, use data to construct the stories that they tell themselves about themselves. [...]

Self-qualification is present from the beginning, as decisions about what to measure and how to do so are highly subjective, and rest upon subject narratives. [...]

Self quantification is a process bookended by self qualification. Yes, the numbers are important. Self-quantification is, by definition, self-knowledge through numbers. Those numbers, however, take shape qualitatively. They become the code with which self-quantifiers prosume selves and identities into being. They are the bits with which self-quantifiers make sense of their atoms. ”
