In the present study, we investigated two literature bases by way of a community survey across Australia. We investigated four acculturation orientations (assimilation, multiculturalism, color-blind, and polyculturalism ideologies) and the motivations to respond without prejudice. We examined what predicted support for Harmony Day as well as explicit discrimination. Multiculturalism, polyculturalism, and internal motivation to respond without prejudice correlated with positive attitudes in both scenarios. External motivation to respond without prejudice was positively correlated with discrimination. Conversely, color-blind ideology had no effect, and assimilation ideology related positively to explicit discrimination and negatively with Harmony Day. Using a multiple regression analysis, there was a difference in emphasis in different contexts. Our findings provide antiprejudice practitioners with material for discussions which can promote positive intergroup relations.Australia prides itself on being a multicultural nation and our lack of racism and prejudice. Yet, evidence of racism throughout Australian history and in contemporary times is overwhelming. A recent example was the 2005 Cronulla Riots where white Australians attacked people of Middle-Eastern descent; in some cases, ripping off the hijab of young Muslim women (Dunn, 2009). Australian authorities, however, do not accept that racism is a problem in Australian society. For example, former Prime Minister John Howard stated "I do not accept that there is underlying racism in this country" after the Cronulla Riots (Davies & Peatling, 2005). Indeed, he rebranded "racism" and "multiculturalism" as "harmony," including, in 1999, renaming the UN international day for the elimination of racial discrimination as "harmony" day. Furthermore, there have been a number of what some researchers argue are other racist attacks; for example, the attacks on Indian students in Melbourne (Dunn, Pelleri, & Maeder-Han, 2011). Again, our politicians denied the role of racism in such events. For example, former Prime Minister Kevin Runn stated "I do not believe that racism is at work in Australia after the attacks on Indian students" (O'Malley & Wade, 2010). There is a great deal of evidence to suggest that prejudice and racism exists in Australia toward a number of marginalized groups such as Muslim and Indigenous Australians (Griffiths & Pedersen, 2009) and asylum seekers (Every & Augoustinos, 2007). This, of course, is not conducive to a cohesive and just society. Thus, in the present study, we investigate ideological factors relating to prejudice and discrimination in the Australian setting.Individuals use belief systems to understand and construct their social reality (Levy, West, & Rosenthal, 2012). Belief systems have the ability to direct behavior, cognitions, and emotions to serve personal needs . Belief systems regarding diversity express how individuals think other groups should behave and how public policy should be shaped; these are referred to as ideologi...
