This section interrogates the relationship between the researcher and the communities being studied. A contextual analysis of this question is important to the idea of ethical research. This mandates an examination of the history of research on non-white groups and in the developing world, and considering the attitudes of researches to study subjects, as well as the relationships of power and information that make clinical research problematic. Such questions as the availability to the public of study data, the capacity to implement research results, and for whom and to whose benefit is the research will be raised.
