Pre-registered stratified experiments can isolate threat-type effects on identity

Evidence

We test our hypotheses with a stratified, pre-registered experiment conducted in late May 2022 with 2,000 White Democrats and 2,000 White Republicans (N = 4,000) (see Supplementary Information [SI], Section 1). Power analyses with G*Power3 revealed that N = 394 per cell was needed to detect a small effect (d = .20) with . power. We partnered with YouGov to administer our study. Eligible non-Hispanic White adults from YouGov’s panel, who self-identified as Democrats or Republicans, were invited to participate. YouGov interviewed 4,114 non- Hispanic Whites from their panel, who were then pared to N = 4,000. This sample was blocked by partisanship. YouGov then matched these respondents (via propensity scores) to a sampling frame on gender, age, and education based on known characteristics of Democrats and Republicans from the 2020 Cooperative Election Survey. — Efrén Pérez, Jessica HyunJeong Lee, Ana Oaxaca, Tania Solano Cervantes, Jasmine García Rodríguez, Kimberly Lam, and David McFall, Manifold Threats to White Identity and…, 33
