Objectives:
The aim of this article is to explain the essence of qualitative research in terms of its broader applicability, including in security sciences.

Material and methods:
To explain the problem, they mainly used the method of examining the content of the literature on the subject and dialectical reasoning, which were sufficient to explain the problem and achieve the goal. This article is of a review nature and refers to selected studies in which various authors explained the assumptions of conducting qualitative research in the disciplines they represented. The authors are aware that the issues of conducting qualitative research are widely described in Western and national literature, especially in ethnology and cultural anthropology, sociological sciences, pedagogy, management and quality sciences, and psychology, and are interpreted differently depending on the discipline in which they are applied. Therefore, the article refers to those selected assumptions that can be creatively applied in security sciences.

Results:
The findings of the study indicate that some researchers in security studies avoid conducting qualitative research as their main methodological approach, instead using qualitative research methodology as a supplement to other approaches to fact-finding.

Conclusions:
The authors put forward the thesis that a comprehensive explanation of a specific problem in security sciences requires the use of mixed research methodology, appropriate to the problem being explained, the research objective, the subject being studied, and the hypotheses being verified. The authors argue that in the research process, we do not test specific epistemological assumptions, but through the diversity of their application, we strive to achieve the most probable result.
