Local paradigms are social paradigms existing in narrow research fields, with aspirations to expand beyond its original scope. Most often they are dominated by the great supralocal paradigms, which overshadow entire disciplines. However, the local paradigms most often give rise to the emergence and existence of research schools such as the Lodz school of methodology. This school, which focused primarily on the sociological survey research, is the subject of the article. The authorl also examines the paradigmatic nature of certain concepts of surveys, developed principally by Jan Lutynki as well as the conflict of the paradigm originated in the Lodz school with another local paradigm. Finally, the author relates to the idea of local paradigms understood as separate worlds and reports on the ways their departures - hence the title of the article.
