This second empirical chapter argues that there was a qualitative difference in the development of epistemic infrastructures in global social security policy between the pre- and post-WWII period. While before, comparisons were strongly politicized, comparison in the post-WWII period is approached much more as a technical process, which, accordingly, presents comparability as solvable through epistemic work, resulting in categories and classifications to become increasingly standardized and uniform. First, the chapter elaborates on how contributions to the ontological framework in the post-WWII years have shifted from politicization to depoliticization. The chapter, second, discusses how comparability was not anymore fundamentally questioned but instead relied on existing epistemic conventions, before addressing, third, the role of expert work in the process. It shows, fourth, that the way in which epistemic infrastructures were advanced further solidified a statutory and Western or European bias of social security.
