This third empirical chapter demonstrates that epistemic infrastructures in global social policy do not only consist of classifications, concepts, and definitions—an ontological framework—but can also involve an evaluative framework, which allows for differentiating orders of worth. The empirical analysis in this chapter shows that while evaluative knowledge was first experimented with already in the interwar years, it only gained traction after WWII. The chapter ends with an analysis of the construction of an epistemic object: the policy model of conditional cash transfers.
