This paper presents an overview and primer on the postpositivist philosophy of critical realism. The examination of this research paradigm commences with the identification of the underlying motivations that prompted a personal exploration of critical realism. A brief review of ontology, epistemology and methodology and the research philosophies and methods popularly applied in accounting is then provided. The meta-theoretical basis of critical realism and the ontological and epistemological assumptions that go towards establishing the ‘truth’ and validity criteria underpinning this paradigm are detailed, and the relevance and potential applications of critical realism to accounting research are also discussed. The purpose of this discussion is to make a call to diversify the approaches to accounting research, and – specifically – to assist researchers to realise the potential for postpositivist multiple method research designs in accounting. This is aided through an illustration that functions to highlight how and why this approach was applied in a real-world accounting research study.
