The existence of collective guilt and its influence on pro-social behaviours was investigated in the context of Indigenous and Non-Indigenous reconciliation in Australia. After the presentation of one of three (negative, positive, ambiguous) one-page Australian histories, 80 psychology undergraduates (47 females) from the Northern Territory University, aged from 18-50 years, indicated their level of national identity, perceived in-group variability, feelings of collective guilt, and how participants and the government should compensate Indigenous groups. Participants were also shown an internet petition, a ‘Sorry list’ apologising to Indigenous Australians, to which they could add their name. Perceptions of in-group variability, collective guilt, and out-group compensation were found to be dependent on participants' level of national identity. In order to facilitate reconciliation, the present data indicate psychographic segmentation of the Australian population, in order to tailor specific reconciliation information to these groups.
