The modern method of assessing attitudes on race is the Implicit Association Test, or IAT, which tests unconscious bias. According to a recent study, 70 percent of whites have an anti-black bias, as do 50 percent of blacks, says Asrat.
So how do those results differ from the original "doll test" results that started decades ago? 50% of blacks have an anti-black bias? Do you even comprehend what that means?
