The study of AIDS, as a disease, a social problem, or, in my case, as a political phenomenon is necessarily difficult and invasive. Learning about AIDS requires invasion of the most private spheres of peoples' lives, involves watching people at their most vulnerable, and often requires becoming closely involved with people whose lives and circumstances are far away from the researcher's own comfort zone. As the title of this essay suggests, my research has led me to take on a variety of roles; first, in order to gather the information I sought and, later, because of the information I had gathered. Roughly speaking, these roles can be characterized with respect to the distance of the researcher from the subject matter. As a scholar, I endeavored, particularly in the early stages of my research, to hold myself apart from what I saw and to compare my findings against those of other researchers. However, as time moved on, I found myself increasingly playing two other roles, roles I have come to characterize as witness and activist. My efforts to lessen the distance between the subjects of my research and myself resulted from both practical and personal motivations. As a practical matter, like many other social scientists, I quickly discovered that I had far greater access to information—in the form of written documents, interviews, and observation opportunities—as an insider. Personally I found myself wanting to contribute what I could to help solve, or at least lessen the severity of, the problems unfolding all around me.As I have moved closer to the subjects of my research, and to the perspectives they hold, I have been forced to confront head-on a perennial dilemma of scholars: objectivity. How does one study an issue “objectively,” particularly when the issue is fraught with controversy? Does taking a side render future observations invalid? Is there some magic line between researcher and subject that is not to be crossed? If so, where is it?The findings presented below represent what I have discovered about interest organizing and political activism in the context of AIDS.
