Thomas addresses the question: if the duty of the researcher entails the righting of social wrongs as well as producing valid research results, how is it possible to juxtapose the two goals? He defines the rules and guidelines for a praxis-oriented ethnographic tradition, one both ideologically engaged and scientifically valid. In addition, he outlines the various types of critical ethnography, explaining the tenets of each and how research can be carried out under these frameworks.
