The present research is within the framework of the normative perspective of the analysis of Linguistic Intergroup Bias (LIB). It starts from the observation that the specialized literature does not indicate the conditions under which individuals disapprove the use of these biases. In this vein, its aim is to help fill this theoretical gap by assessing the potential impact of linguistic abstraction on intra-group disapproval of the use of LIB. The tested hypothesis proposes that individuals disapprove more the use of LIB when they face a speaker who uses pro-ingroup and anti-outgroup LIB, than when they are confronted with a speaker who uses pro-outgroup and anti-ingroup LIB. This prediction is tested thanks to an experiment conducted with the participation of fifty (50) students of both sexes (M age = 22.94 years), all French speakers, enrolled in the first year of the Bachelor of Psychology’ program at the University of Dschang (Cameroon). They were assigned to the experimental (n = 25) and control (n = 25) conditions constituting the experimental design. After experimental induction, the data collected via the scale of intragroup disapproval of the use of LIB (α =.75) provide empirical support for the hypothesis of the study (f (1; N = 51) = 52.31, ŋ =.995, Ŋ2 =.989, t = 7.42, ƿ <.05). In conclusion, this study reveals that individuals disapprove the use of LIB when ingroup prescribes disapproval of these biases (group norm).
