Free listing exercises are common and informative ways to explore shared bodies of knowledge and practice, and they can probe widely experienced phenomena in daily life. However, even with a representative sample, this method can suffer under common conditions in anthropological fieldwork: Respondents forget to list items, they fail to provide exhaustive lists, they become fatigued during the interview process, and their responses may not provide representative information. In this article, I suggest an iterative process that combines targeted free listing with key informants, walking probes, and a survey checklist. During an investigation of agricultural biodiversity in Telangana, India, this approach generated more comprehensive lists than free listing exercises alone. This process generates checklist surveys appropriate for larger research populations and can be used to assess widespread knowledge and practices quickly, accurately, and with minimal respondent fatigue.
