A new study has found that southern whites are more likely to house unconscious racial bias against Blacks stemming from the region's dependence on slavery, well over a century ago.

"Counties and states with a higher proportion of their populations enslaved in 1860 had greater anti-black implicit bias among white residents," the researchers report according to Pacific Standard. 

The study reports that the reason for whites, unconscious bias "was associated with [1860] slave populations, but not with modern black populations.

University of North Carolina psychologist B. Keith Payne led the study.

"Counties and states more dependent on slavery before the Civil War displayed higher levels of pro-White implicit bias today among White residents and less pro-White bias among Black residents. These associations remained significant after controlling for explicit bias. The association between slave populations and implicit bias was partially explained by measures of structural inequalities."

Payne and his also found that counties and states with a greater percentage of slaves 160 years ago have higher levels of racial segregation today, as well as a higher proportion of Blacks living in poverty. This means that in the south, Blacks have less access to high paying jobs, better housing conditions, and high-level education institutions than their white peers.
