Based on field research on Andean medicine men and West Tibetan (Ladakhi) shamans, this paper delineates some research problems which arise from the lies told and amnesia experienced by indigenous informants. It is shown that the problem of amnesia leads to the paradox that "one can only do research on shamans by ceasing to do research." In discussing four hypotheses for understanding shaman's amnesia, as a "lie," as a professional ideology, or as an artifact of Western research, a solution is (...) sought for this paradox. The best solution is seen in an approach called "recycling the waste" in which lies, inventions, contradictory and fragmentary information (usually considered as the "waste" of research) are being "recycled" as valuable data in their own right.
