In this essay, we highlight the interplay between individuals' psychological processes and sociocultural systems in producing and maintaining racial bias. We use a conceptual tool we call the culture cycle to map these dynamics, and illustrate them with research and in-depth examples from our work reducing racial disparities in routine policing in Oakland, California. We feature the most common police encounter – the vehicle stop – and highlight evidence-based interventions we developed both to reduce the frequency of vehicle stops and mitigate racial disparities in stops. Throughout, we draw on our expertise in the social psychology of bias, culture, and inequality, as well as our experiences building research-driven partnerships with public- and private-sector leaders, to inform organizational and societal change.

We describe the rise of “opportunity markets” that allow well-off parents to buy opportunity for their children. Although parents cannot directly buy a middle-class outcome for their children, they can buy opportunity indirectly through advantaged access to the schools, neighborhoods, and information that create merit and raise the probability of a middle-class outcome. The rise of opportunity markets happened so gradually that the country has seemingly forgotten that opportunity was not always sold on the market. If the United States were to recommit to equalizing opportunities, this could be pursued by dismantling opportunity markets, by providing low-income parents with the means to participate in them, or by allocating educational opportunities via separate competitions among parents of similar means. The latter approach, which we focus upon here, would not require mobilizing support for a massive redistributive project.
