We are a long way from knowing precisely what happened in Ferguson, two weeks ago, but one thing is clear: The town’s name has become yet another synonym for the chasm of experience dividing white and black America. Time and again, young African-American men have been fatally shot by police under ambiguous circumstances: Amadou Diallo, Oscar Grant, Sean Bell … the list goes on. Yet public opinion polls show that a majority of whites consistently fail to see a racial component to these incidents.Part of this perceptual gap stems, I believe, from a fundamental misunderstanding of the nature of prejudice today. Say “racism” and most Americans visualize Bull Connor and his dogs, or Gov. Wallace at the schoolhouse door. Yet psychological scientists have long known that the problem is far subtler and more insidious. The stereotypes and prejudices that people harbor today reside outside of their conscious awareness, causing them to behave discriminatorily despite their best intentions. One of these enduring stereotypes is associating blacks with crime and violence.
This is just as true — but the consequences most profound — in the split second when police have to decide whether to use lethal force. In psychological research simulating street conditions, police are faster to shoot armed blacks than armed whites, and more likely to shoot unarmed blacks than unarmed whites. Other research has shown that when police officers are subliminally influenced to think of black men, they are faster to identify weapons; when they are primed to think of crime, their visual attention gets drawn to black faces.
Police are normal human beings with normal human cognition doing an abnormally difficult job. Part of that means that they harbor the same implicit stereotypes and prejudices that the rest of us do, and these biases can cause them to behave in ways they don’t consciously want to. When placed in a potentially fatal situation, they have a fight-or-flight response that compromises higher level brain functioning. At that point, they have to rely on extensive training to follow basic protocol, but subtler distinctions are difficult.
The issue of nonconscious bias is also at the root of the current dispute over the failure of St. Louis County Prosecuting Attorney Robert McCulloch to recuse himself from the case. The problem at issue is very serious. When McCulloch was 12 years old, his father, a police officer, was shot to death by a black assailant. Because the current case involves a white officer allegedly being confronted by a black assailant, McCulloch’s personal history raises reasonable questions about whether he can be objective.
But consider McCulloch’s dilemma: If he recuses himself from this case for this reason, after being county prosecutor for 20 years, he will signal that his objectivity is in question for any prior or future case involving white officers, black suspects and force, a scenario that represents a good share of the cases he — and almost any other American prosecutor — will take.
In this case, however, justice must be served with unambiguous fairness. Mr. McCulloch’s objectivity is tainted by his tragic past. We cannot blame him for this and shouldn’t fault him for believing he can be objective. But we know that our conscious goals are often contravened by our nonconscious biases. Furthermore, even the appearance of a conflict of interest is enough to undermine the legitimacy of this process.
The obvious solution is for Gov. Jay Nixon to remove McCulloch from the case. This will allow McCulloch to maintain his claim of professionalism and integrity, and it will allow the community to move forward without the distraction of McCulloch’s unique personal history. It will not, however, solve the endemic problem of racial bias in the criminal justice system. For that, there is much work to be done.
