Abstract
Based on her own biographical experience, the author presents the process of thoughtless accepting by a young scientist a certain “thought collective” (theoretical category introduced by Ludwik Fleck) that dominates in the practised discipline, namely pedagogy. A chosen object of that style of thinking is the way of conducting empirical research. The young researcher did not behold its limitations although they have been pointed out by a representative of another discipline (a psychologist). Beholding these limitations and the convention of all kind of research models has become possible only as a result of group studies on methodology of social research.
