Critical realism: what you should know and how to apply it

Abstract

PurposeThe purpose of this paper is to discuss the critical realism (CR) philosophical viewpoint and how it can be applied in qualitative research. CR is a relatively new and viable philosophical paradigm proposed as an alternative to the more predominant paradigms of positivism, interpretivism and pragmatism. This paper reviews the concept, its benefits and limitation. It goes further to provide an example of how CR is used as a philosophical and methodological framework with the systems thinking theory to applied qualitative research.Design/methodology/approachA study of project management challenges in a Nigerian government organisation is used to demonstrate a qualitative research approach, which includes a coding process and data analysis that is consistent with CR ontology and epistemology.FindingsCR focuses primarily on closed systems. However, a more accurate explanation of reality is obtained in addition to the identification of contextual causal mechanisms in the context of study when a general systems theory is applied.Research limitations/implicationsThe knowledge about the nature of relationships obtained in the context of study may not necessarily be replicated in another context. However, this paper elucidates a CR process that is generalisable by demonstrating how a theory is applied in a different context.Originality/valueThe paper demonstrates how systems theory is used to understand interactions in a CR paradigm. It engages with CR approach critically and illustrates a clear example of how CR can be applied in social research.
