To well understand the phenomena that we could generally define as a “total social fact”, a more articulate method is profitable. Moreover, the “biographical work” [Inowlocki & Lutz, 2000] calls for competences in different disciplines. In addition to interdisciplinarity, this work demands that the researcher moves from “micro-sociological” level to “meso” and “macro” ones, passing through interactions and transitions. To achieve a complete comprehension of the interviewees’ stories and to deepen the issue of research, it is necessary to better describe and to experience interviewees’ life in time, space and movement. For this, the interviewer as a researcher, cannot be satisfied with the récit, he/she has to widen the observation, to “be part of the stories collected” and to participate in his/her field at different levels.
I come to the conclusion that ethnography, in particular the Burawoy and Marcus outlines, seem to be essential to give a three dimensional form to the biographical work. There is a strong alliance between these methods that empower the outcomes of biography analysis. Probably, the weakness is in term of time and engagement, considering the commitment in social research.
