In the research article, "Imaging Race [2]" (American Psychologist , Feb-Mar 2005), Stanford University psychologist Jennifer L. Eberhardt describes how brain imaging reveals "the neurobiological effects of people's racial beliefs, attitudes, and knowledge in a manner that appears to highlight (both to scientists and to laypeople) the socially constructed nature of race." While in the past, science, especially neuroscience, had been used to reinforce racial stereotypes and hierarchies, today neuroscience may be a tool to break down racist beliefs that lead to discrimination.
