This chapter is based on long-term research with people affected by the Ok Tedi mine in Papua New Guinea, including involvement in a lawsuit seeking to halt its destructive environmental impact. It considers examples of ethnographic refusal, when anthropologists do not write about events that might harm their informants. It also examines relationships between engaged anthropologists and colleagues, lawyers and law, corporations, nongovernmental organizations, and communities. This chapter and the next address these questions in the context of long-term research projects, while the other examples in the book consider these issues in relation to short-term, problem-focused research, which have their own challenges and opportunities.
