Omnivorousness as the bridging of cultural holes: A measurement strategy

Recent research and theory at the intersection of cultural sociology and network analysis have converged around the notion of cultural holes: patterns of cultural choice that position the person as a bridge not between other persons but between cultural worlds. This is an approach that promises to open up new vistas in our conceptualization of the relationship between social position and cultural taste, but that so far lacks operational grounding. In this article, I draw on Breiger’s (1974) formalization of the idea of the duality of persons and groups along with classical formalizations of brokerage for sociometric networks (Burt 1992) to suggest that the “cultural ego network” of a typical survey respondent can be reconstructed from patterns of audience overlap among the cultural items that are chosen by each respondent. This leads to a formalization of the notion of omnivorousness as relatively low levels of clustering in the cultural network: namely, omnivorousness as cultural network efficiency. I show how this metric overcomes the difficulties that have plagued previous attempts to produce ordinal indicators of omnivorousness from simple counts of the number of cultural choices, while providing novel substantive (and sometime counter-intuitive) insights into the relationship between socio-demographic status markers and patterns of cultural choice in the contemporary United States.
