This conclusion presents some closing thoughts on the concepts covered in the preceding chapters of this book. The book focuses on figures that are located at the core of the humanitarian doxa – numbers of refugees, numbers of acute malnourished children, crude mortality rates, number of people in need. The hubris of humanitarian data has been fueled by doubts long before it has been fueled by arrogance. The book shows that a major change had taken place between Henri Dunant and Jean Pictet. It also shows how a United Nations agency like the UN Refugee Agency (UNHCR) has learned to classify the needs of refugees. The UNHCR thus contributed to the export and diffusion of needs classifications. The book looks at how concepts, classifications, tools, and standards came together in Cameroon in the wake of the Central African crisis in 2013/2014. The universalist position has been more and more supported by an infrastructure of commensurability that allows for transnational interventions.
