Changed perception during investigation counts as valid evidence, not bias.

Evidence

A meaningful thematics is expressed by people, and a given moment of expression will differ from an earlier moment, if they have changed their perception of the objective facts to which the themes refer. From the investigator’s point of view, the important thing is to detect the starting point at which the people visualize the “given” and to verify whether or not during the process of investigation any transformation has occurred in their way of perceiving reality. (Objective reality, of course, remains unchanged. If the perception of that reality changes in the course of the investigation, that fact does not impair the validity of the investigation.) — Paulo Freire, Pedagogy of the Oppressed, 307
