The problem with propositions: theoretical triangulation to better explain phenomena in management research

In management research, theory is commonly viewed as a set of propositional statements backed up by theoretical assumptions. This view is embraced across conceptual and empirical research and effectively binds a particular style of reasoning, as a common grammar, to a specific form that theoretical explanations, as a structured set of propositions, should take. In this paper, I analyse the characteristics of the propositional grammar and highlight several significant problems including its high incidence rate of false positives in empirical research (false hypotheses that are accepted as true) and how it generally limits our explanation of phenomena by casting them as effects to be predicted. Informed by this analysis, I make the case for theoretical triangulation and offer a prescriptive model whereby researchers can strengthen their explanations of phenomena by iterating across multiple theoretical grammars rather than steadfastly using a single grammar. Using examples from prior research, I show how such theoretical triangulation helps mitigate the specific inferential biases and threats to validity of any grammar and leads to better explanations overall. I conclude the paper with spelling out the implications of this argument and offer a set of practical recommendations for implementing the practice of theoretical triangulation.
