With the rise of Trump, the fall of racial prejudice?

Stanley-Becker points to a fascinating study by Hopkins and Washington. Their abstract:

In his campaign and first few years in office, Donald Trump consistently defied contemporary norms by using explicit, negative rhetoric targeting ethnic/racial minorities. Did this rhetoric lead white Americans to express more prejudiced views of African Americans or Hispanics, whether through the normalization of prejudice or other mechanisms? We assess that question using a 13-wave panel conducted with a population-based sample of Americans between 2008 and 2018. We find that via most measures, white Americans' expressed anti-Black and anti-Hispanic prejudice declined after the 2016 campaign and election, and we can rule out even small increases in the expression of prejudice. These results suggest the limits of racially charged rhetoric's capacity to heighten prejudice among white Americans overall. They also indicate that prejudice can behave like an issue attitude: rather than being a fixed predisposition, prejudice can respond thermostatically to changing presidential rhetoric and policy positions.

Stanley-Becker quotes Hopkins:

...it’s quite conceivable that Trump has simultaneously galvanized a small number of highly prejudiced white Americans while also pushing millions more to affirm that they are not as prejudiced.

Hopkins said his discovery is not out of step with other assessments. In fact, his conclusions are in line with recent scholarship suggesting that bias, both implicit and explicit, has declined when it comes to race and sexual orientation, though prejudice has remained steady regarding people with disabilities and actually increased regarding obesity.

The recent scholarship Hopkins references is work from Banaji's group:

Using 4.4 million tests of implicit and explicit attitudes measured continuously from an Internet population of U.S. respondents over 13 years, we conducted the first comparative analysis using time-series models to examine patterns of long-term change in six social-group attitudes: sexual orientation, race, skin tone, age, disability, and body weight. Even within just a decade, all explicit responses showed change toward attitude neutrality. Parallel implicit responses also showed change toward neutrality for sexual orientation, race, and skin-tone attitudes but revealed stability over time for age and disability attitudes and change away from neutrality for body-weight attitudes. These data provide previously unavailable evidence for long-term implicit attitude change and stability across multiple social groups; the data can be used to generate and test theoretical predictions as well as construct forecasts of future attitudes.
