We examined, in two experiments, the notion that members of low status groups, more than members of high status groups, use outgroup helping as a strategic tool to demonstrate their group's knowledge and boost its reputation. In Study 1 (N=103), we compared outgroup helping in response to requests for help with offering help. As predicted, participants' knowledge was positively related to outgroup helping in response to requests, but only among members of low status groups. Knowledge also predicted the offering of help among members of high status groups. The second study (N=75) replicated the findings from the requested help condition and showed that the effect disappeared in a condition in which help could not reflect ingroup knowledge. Additional data support a conclusion in terms of a collective strategy to boost the ingroup's reputation by demonstrating ingroup knowledge to the outgroup. The implications for promoting outgroup helping in a salient intergroup context are discussed. © 2010 Elsevier Inc.
