In my mind, we all smile:: A case of in-group favoritism

The goal of the present study was to examine whether a highly valued social behavior-the smile-is attributed more frequently to in-group than to out-group members. For this, participants were asked to read a vignette describing a protagonist in a nonemotional situation, and to choose a facial expression that would be appropriate to the context. For Study 1 the vignette depicted a potentially social context, whereas for Study 2, the context was strictly non-social. In both studies, participants of European descent attributed smiles more often to members of their in-group, whereas they attributed a larger number of neutral faces to out-group members. In a third study the same pattern of attributions was found for recent immigrants from French speaking African countries and from Asian countries. These results suggest the presence of an in-group bias in the attribution of smiles. (C) 2003 Elsevier Science (USA). All rights reserved.
