Abstract
Prior research has found that white people are more likely to be climate change skeptics. In much of this prior work, white identity is treated as a categorical label, limiting the theoretical and empirical understanding of this relationship. Drawing on survey data from a US national sample of 933 white young adults, we theorize that white identity is a developmental process where people explore the meanings of their racial identity and commit to a white identity marked by enhanced levels of social dominance orientation and conspiratorial ideation, two social-psychological constructs consistently associated with climate change skepticism. Using regression analyses, we tested a mediation model that a strong white identity would increase climate change skepticism by enhancing one's social dominance orientation and conspiratorial ideation. We found partial support for our model. While a strong white identity was positively associated with social dominance orientation and conspiratorial ideation, only social dominance orientation increased climate change skepticism. Conspiratorial ideation reduced climate change skepticism. We discuss the implications of our findings for the climate change literature as well as how our findings can inform policies that could reduce climate change skepticism among white people.
