The effects of racial status threat on White Americans’ support for Donald Trump: Results of five experimental tests

Abstract

Prior theory and research suggest that threats to the status of White Americans may increase support for Donald Trump. Consistent with this, one previous experiment conducted in early 2016 documented this effect (Major et al., 2018), finding that making salient the declining White majority in the United States increased support for Trump’s presidential candidacy among White participants with high levels of ethnic identification. We report the results of five very similar experiments (total N = 3,076) also conducted in 2016, including one conducted on a national probability sample. The first experiment (conducted in January 2016) found that racial status threat increased Whites’ support for Trump. The other four (conducted from February to October 2016), however, all found null results, and an internal meta-analysis of the five studies found no significant main effect overall. Additionally, none of the studies found an interaction of racial demographic shift and ethnic identification in which racial demographic shift increased Trump support among high-identifying Whites. We conclude by discussing a variety of potential explanations for our findings, including (a) that racial status threats did not increase Whites’ Trump support, (b) that racial status threats increased Trump support early in the 2016 election cycle, but the role of this factor in Trump support declined over time, or (c) that this pattern is an example of a broader tendency of declining experimental treatment effects on candidate support over time in campaigns (Kalla & Broockman, 2018).
