The distinctions of Heideggerian phenomenological research method

PurposeThis current paper attempts to bring more light to the current debate of understanding phenomenological research methods, in order to clarify the interpretive phenomenological inquiry with Heidegger's philosophy of phenomenology.Design/methodology/approachThe paper uniquely presents the three distinctions of Heideggerian thoughts in conducting interpretive phenomenological research: (1) realizing the problem of identity; (2) recognizing the inadequacy of ontology; and (3) interpreting the subject matter through historical critiques.FindingsThe paper also discusses the basis of phenomenological research issues of a priori knowledge, data analysis process and qualitative research issues of validity, reliability, and creditability. In the conclusion and recommendation, this paper suggests six key points to implement a proper research strategy to employ Heideggerian phenomenological inquiry in social science and policymaking research where investigators are dealing with the multiplicity of existing and alternative worldviews.Originality/valueThe paper idea is fresh and adds new knowledge to the field.
