Stuck data, dead data, and disloyal data: the stops and starts in making numbers into social practices

Indicators with long social histories, such as the Consumer Price Index, often serve as nodes of calculative infrastructures. They create a field of social action, making some relations between people, institutions, and materials possible, and other relations less possible. By reflecting on two experiments in do-it-yourself sensor data, this article explores the tensions that occur when indicators have not yet become stable entities. When the conditions of possibility for the indicator's continued existence are less assured, the labor it takes to build numbers into something socially meaningful becomes surprisingly visible. This labor proceeds in stops and starts, as the various material and epistemological and social resistances reveal themselves. Sensors shape these starts and stops. Sensors give their users an indication of a possible whole entity whose contents they cannot fully imagine, and either must create or abandon. Far from producing certainty, sensor data often provokes a sense of vagueness that is worked on until it becomes either clarity or action, failure or indifference. Through this view of numbers in the making, we can see just how remarkable it is that indicators become part of calculative infrastructures at all.
