Pre-understanding – our presuppositions of reality – underlies all research. Many researchers probably also draw productively on their pre-understanding in their studies. However, very few rationales and methodological resources exist for how researchers can enrich their research by mobilising their pre-understanding more actively and systematically. We elaborate and propose a framework for how researchers more actively, systematically and visibly can bring forward their pre-understanding and use it as a positive input in research, alongside formal data and theory. In particular, we show how researchers, in dialogue with data and theory, can mobilize their pre-understanding as an interpretation-enhancer and horizon-expander throughout the research process, including stimulating imagination and idea generation, broadening the empirical base, and evaluating what empirical material and theoretical ideas are interesting and relevant to pursue.
