This article examines culture, an ambiguous yet prevalent concept in comparisons of crime and justice. It investigates the extent to which culture’s application and meaning across research reflects Western-centric bias in criminological knowledge-production despite it being a concept meant to advance understanding on different groups and places beyond the “Western” worldview. The article extends the discussion on Western-centric bias but also on culture in criminology by tracing the use of this concept on East Asian populations and by identifying patterns of application and meaning in international and comparative research through a scoping review of 230 journal publications. The findings address patterns of culture’s appearance in criminology journals in the past two decades and its meaning. Similar to previous scholarship on Western-centrism in criminology, the article finds that this bias does, too, exist in uses of culture but also shows how culture’s conceptual ambiguity is conducive to this bias, in that some groups and places are given one meaning of culture while others receive another.
