The subjectivity of both a researcher and her research subject respectively forms the subject matter of qualitative research. The context of subjectivity, phenomenologically manifest as lived experience, can be interpretively pushed towards frontiers of knowledge that quantitative research, by its very definition, seeks to avoid. By virtue of its inherent capability, qualitative research can tackle the complexity of the universal phenomenon of Lebenswelt which at the same time is highly particularised via the Dasein of the researcher and the research subject respectively. In other words, qualitative research has existential pontentiality as its hallmark.
