 Another critical review, by Dr. Debra Picchi, argues that the book was invalid as social science because of the author's auto-biographical focus on her personal development and experience, rather than on describing the Yanomami people.One critic suspected that Donner might have worked from the many ethnographic movies about the Yanomami and argued that in that case her book could be considered an interpretive study of the visual documentary data.The validity of De Holmes' critique was largely accepted by the anthropological community.
