With personal information an overt ‘site of struggle’ in contemporary politics, how do non-state actors gather data but also craft their authority to do so? This chapter shifts the site of Informational Relations spatially, away from the lofty ‘international’, as well as temporally, to earlier in this chain of events. The authority of non-governmental organizations (NGOs) to gather data is often treated as antecedent, but collecting Others’ information and acting as repositories are themselves invocations of authority. While a key driver of this book has been the importance of ideas in crafting everyday authority, legitimation’s material consequences are highly conspicuous in this process of gathering information: it is a core NGO ‘currency’. This chapter focuses on the collection of data, whereby the authority of NGOs is instantiated through acts of monitoring and verification, both laterally with respect to peers and vertically to communities. It pits NGO against NGO; NGO against local government; village volunteers against their leaders and peers. NGOs thus find themselves enmeshed within a complex informational ecosystem that is truly global. Given the clear fungibility of information, the gathering of data proved one of the most contentious legitimation practices.
