Field trips play a significant role in the building of expert knowledge of numerous institutions. So why is their nature and significance for knowledge production rarely discussed in the anthropology of expertise? In this paper, I draw on the particular instance of an expert field trip undertaken by a disaster management organization in the Indian state of Odisha in the aftermath of Cyclone Phailin in 2013. I show that field trips are contingent practices defined by their sequential logic, relationships, interests, and by the personal perceptions of people who undertake them. The choice of personnel to carry out this field exercise is fundamental and depends on institutional views of aims and understandings of what constitutes expertise. In line with E. Summerson Carr’s argument that expertise is something people “do” rather than “hold”, I show that enacting expert status serves to assert power and to enable its holder to achieve their aims.
