Cultural Omnivorism refers to a pattern of taste characterized by broad and eclectic engagement with cultural forms that cut across conventional hierarchies of high and low culture. First articulated by Richard Peterson in the 1990s, the concept challenged earlier sociological models—most notably Pierre Bourdieu's theory of distinction—which posited that elite status was signaled through exclusive consumption of "highbrow" culture and rejection of popular or "lowbrow" forms. Peterson's empirical work found that individuals of higher socioeconomic status increasingly display omnivorous consumption patterns, appreciating opera alongside country music, or fine dining alongside street food, rather than confining their tastes to a narrow band of prestige goods. This shift has been attributed to several interrelated factors: the erosion of rigid status boundaries in postindustrial societies, the rise of cultural globalization and media diversification, generational value change favoring tolerance and cosmopolitanism, and the strategic deployment of eclecticism itself as a new marker of cultural capital. Subsequent scholarship has extended and complicated the omnivore thesis, examining its cross-national variation, its intersections with race, gender, and age, and questioning whether omnivorousness represents genuine egalitarianism or a subtler, more flexible form of distinction. This paper reviews the theoretical origins, empirical evidence, and critical debates surrounding cultural omnivorousness, arguing that it remains a productive lens for understanding how taste operates as a mechanism of social stratification in contemporary societies, even as the boundaries it once mapped continue to shift.
