Abstract Explicitly prejudiced attitudes against Black Americans have declined gradually since the 1960s. Yet racial disparities and racial discrimination remain significant problems in the United States. How could discrimination and disparate outcomes remain constant even while racial prejudice decreased? Two prominent explanations have emerged to explain these puzzling trends. Sociologists have proposed that disparities and discrimination are perpetuated by systemic racism, or the policies, practices, and societal structures that disadvantage some racial groups compared with others. Simultaneously, psychologists have proposed that implicit biases may sustain discrimination even in the absence of explicit prejudice. In this essay, we explore newly discovered connections between systemic racism and implicit bias, how they challenge traditional views to reorient our understanding of implicit bias, and how they shed new light on strategies to reduce bias. 

The spatial patterning of present-day racial bias in Southern states is predicted by the prevalence of slavery in 1860 and the structural inequalities that followed. Here we extend the investigation of the historical roots of implicit bias to areas outside the South by tracing the Great Migration of Black southerners to Northern and Western states. We found that the proportion of Black residents in each county ( N = 1,981 counties) during the years of the Great Migration (1900–1950) was significantly associated with greater implicit bias among White residents today. The association was statistically explained by measures of structural inequalities. Results parallel the pattern seen in Southern states but reflect population changes that occurred decades later as cities reacted to larger Black populations. These findings suggest that implicit biases reflect structural inequalities and the historical conditions that produced them.
