On Limitations to the Use of Some Anthropologic Data, published in 1881 by John Wesley Powell, critically examines anthropological data related to North American Indigenous cultures. Powell addresses misconceptions and methodological challenges in interpreting archaeological evidence, language, and social structures among various tribes. He emphasizes the need for careful differentiation between groups to avoid overgeneralization and misinterpretation, making this work a significant contribution to the field of anthropology and a cautionary guide for researchers.
