We examined whether zero‐sum thinking explains White Australian‐born people’s majority‐culture perceptions of discrimination towards their ingroup and an outgroup (immigrants), and the relationships among perceived discrimination and support for multiculturalism and immigration. Two correlational cross‐sectional studies were conducted among self‐identified White Australians (Study 1, N = 517), and White Americans (Study 2, N = 273), as well as an experiment among White Australians (Study 3, N = 121) in which we manipulated discrimination towards immigrants over time. Our findings did not support a zero‐sum account but revealed that perceptions of group discrimination were positively correlated: a case of ‘they’re discriminated against, but so are we’ rather than ‘if they gain, we lose’. Moreover, concerns about future discrimination of the ingroup were most predictive of opposition to multicultural policy and immigration. We argue our findings are more consistent with a competitive victimhood account of intergroup relations than a zero‐sum thinking account.

“他们受到歧视，但我们也受到歧视”：随着时间的推移，出生于澳大利亚的白人对内群体和移民歧视的看法不是零和。

我们研究了零和思维是否解释了出生于澳大利亚的白人对其内群体和外群体（移民）的歧视的多数文化观念，以及感知到的歧视与对多元文化和移民的支持之间的关系。在自我认同的澳大利亚白人（研究 1，N  = 517）和美国白人（研究 2，N  = 273）以及澳大利亚白人（研究 3，N = 121），其中我们随着时间的推移操纵了对移民的歧视。我们的研究结果不支持零和帐户，但揭示了对群体歧视的看法是正相关的：“他们受到歧视，但我们也受到歧视”而不是“如果他们得到，我们就会失去”。此外，对内群体未来歧视的担忧最能预示对多元文化政策和移民的反对。我们认为，与零和思维解释相比，我们的发现更符合对群体间关系的竞争性受害者解释。
