Understanding the legacy of settler colonialism requires understanding the nature and scope of anti-Indigenous attitudes. But what, exactly, are the political consequences of anti-Indigenous attitudes? Answering this question requires recognizing that attitudes toward Indigenous peoples are distinct from White racial attitudes toward other disempowered groups. In this paper, I introduce a novel measure of Indigenous resentment. I then show that Indigenous resentment is an important predictor of policy attitudes using data collected from an original survey of White settlers. I estimate the effect of both Indigenous resentment and negative affect on policy attitudes—opposition to welfare and support for pipeline developments—to make the case that Indigenous resentment is a better measure of anti-Indigenous attitudes than affective prejudice, and that Indigenous resentment is an important omitted variable in the study of public opinion in settler societies.
