Two survey experiments explored how linguistic intergroup bias (LIB) differs according to ethnic identification within a homogenous ethnic group (Hong Kong citizens). Study 1 displayed that Hong Kong citizens who identified as “Hongkonger” employed more abstract expressions to describe prosocial behaviors of the in-group (Hong Kong citizen) and antisocial behaviors of the out-group (Mainland Chinese); those who identified as “Chinese” displayed less LIB. Study 2 found similar results for a context based on location of behaviour (in Hong Kong vs. in China) rather than the nationality of the protagonist. The combined evidence proposes that LIB can have a notable intragroup as well as intergroup dimension.
