Beyond Individualism and Holism: Integrated Information Theory as Formal Framework for the Gradation of Social Structure

In lieu of the sum-zero scenarios of either wholly individualist or holist depictions of social entities, some social ontologists and philosophers of social science have recently called for gradualist approaches able to account for variances in ontological reducibility between specific instances of social phenomena. The precise formal tools needed for this type of approach are, however, currently lacking. In this paper, I propose a new approach to social ontology that utilizes Integrated Information Theory (IIT) in order to provide a suitable formal language for gradualist descriptions and analyses of social entities. In line with the operational physicalism of IIT, social entities are stipulated as causally irreducible to their parts to the degree that differences are made by and to them over and above the differences made by and to their parts.
