“…It is important that brief exposures to crowds (1/3 second each) influenced racial cognition in a predictable manner, but this occurred after exposure to a number of trials (i.e., 216 trials) and the statistically significant effects on racial categorization were on the order of only 5% of total biracial categorizations (i.e., 1 of 21 faces). This effect, however, is still meaningful and not unusual for this area of research (Chen & Hamilton, 2012; Hoffman, Trawalter, Axt, & Oliver, 2016; Kubota, Peiso, Marcum, & Cloutier, 2017; Lloyd, Kunstman, Tuscherer, & Bernstein, 2017). Applying the mechanism we isolated in Study 1 to a lifetime of exposure to crowds could, in theory, have much larger influences on racial category boundaries.…”
