Results revealed that among Asian American participants, Hispanic growth information elicited more conservative policy endorsement, compared with control information, b = 0.36, p = .007, controlling for baseline political ideology. Conversely, Asian growth information did not influence Asian American participants' policy positions, compared with control information, b = 0.13, p = .405. Among Hispanic and Black American participants, the population growth conditions did not differ from control, ps>.340. Analyses of potential mediators through which making outgroup growth salient may affect policy support—e.g., concerns about the societal system/American culture (Jost et al., 2007), concerns about Hispanics and Asians gaining status and resources in society (group status threat/realistic threat; Stephan, Ybarra, & Bachman, 1999) did not show consistent evidence of mechanism. **References** Craig, M.
