Abstract

Animal experimentation, besides a research method extensively applied in the production of scientific knowledge, is also considered essential to science and with undeniable historical relevance in advances in human health. In this survey, a questionnaire was applied to a group of researchers involved with research based on non-animal models (n =18), and to another group involved with research based on animal models (n =18). The data analysis was grounded in Ludwik Fleck (1896 -1961) epistemological assumptions. The results suggested that there are at least two thought styles operating in consonance on the same research problem (advances in human health conditions) with significantly different conceptions not only concerning the research practices involved, but also the historical conceptions related to the role of animal experimentation
