This article analyses the influence of accent on discrimination against immigrants by examining the hypothesis that accent leads to discrimination only in more prejudiced individuals, merely because people speaking with a native accent are perceived to be better qualified than those whose accent is non‐standard. In Study 1 (N = 71), we found that only prejudiced individuals use accent to discriminate against immigrants. In Study 2 (N = 124), we replicated this effect and found that the influence of accent on discrimination is mediated by the perceived quality of the accent. Study 3 (N = 105) replicated the previous results even after controlling for the effect of stereotyping. These results are the first experimental illustration of the hypothesis that accent triggers intergroup discrimination only among prejudiced individuals because they evaluate native accents as being qualitatively better than accents of immigrants, thereby legitimizing ingroup bias.
