ABSTRACT Critical realist thought has theorised convincingly that epistemic relativism is constellationally embedded in ontological realism which in turn necessitates judgemental rationality. In social science, judgemental rationality involves acting upon plausible decisions about competing points of view. However, the tools for doing this are, as yet, under-articulated. This paper addresses this absence by articulating triangulation and depth-reflexivity as two tools for doing judgemental rationality in empirical research. It draws on the experiences of a diverse team working on an international comparative (...) research project on conversion to Islam in prisons. It demonstrates how epistemic and relational gaps between researchers and research subjects can be bridged by mobilising the ‘laminated’ properties and personal attributes of a diverse research team that factors in attributes that are absent as well as those present. The biographical experiences of the team are analyzed in a variety of intersecting dimensions: faith, ethnicity/ethno-culture, gender, class and professionality. (shrink)
