["The British Journal of Sociology, Volume 73, Issue 2, Page 259-272, March 2022. ", "\nAbstract\nThis article examines how white British residents of a superdiverse London housing estate learn about—and subsequently deploy—the intra‐ethnic stereotypes used by their British Pakistani and British Bangladeshi neighbours/flatmates. Building on recent attempts to bring together conviviality and boundary making, along with insights into intra‐ethnic othering, we show how, for white British residents, these stereotypes offered the chance to add detail and authenticity to judgements about the “unrespectable” behaviour of British Asian residents and/or visitors. Ultimately, however, white British residents' inappropriate and/or imprecise deployment of these stereotypes in relation to British Bangladeshis and British Pakistanis led to the misidentification of low‐status people and the unfair extension of discrimination faced by low‐status individuals and families. Furthermore, the combination of clumsy application and the positioning of “respectable” British Bangladeshis and British Pakistanis as purveyors of “insider knowledge” about intra‐ethnic stereotypes led to the reinscribing of boundaries between racial groups. We conclude that studying the cross‐racial use of intra‐ethnic stereotypes allows for a subtler appreciation of the complex dynamics of inclusion and exclusion in superdiverse areas.\n"]
