“The research, published in January in the Journal of Experimental Social Psychology, found that white people characterize a ‘black’ person as belonging to a lower socioeconomic status, being less competent, and having a less inviting personality than an ‘African-American’ person. And this difference in perception could have an impact on African Americans in various settings, from the labor market to the criminal justice system.”
