The science of racism

The Science of Why Cops Shoot Young Black Men

And how to reform our bigoted brains.

By Chris MooneyI WENT TO NYU to learn what psychologists could tell me about racial prejudice in the wake of the shooting of a black teenager, Michael Brown, by a white police officer, Darren Wilson, in Ferguson, Missouri. We may never really know the exact sequence of events and assumptions that led to the moment when Brown, unarmed and, according to witnesses, with his hands in the air, was shot multiple times. But the incident is the latest embodiment of America's racial paradox: On the one hand, overt expressions of prejudice have grown markedly less common than they were in the Archie Bunker era. We elected, and reelected, a black president. In many parts of the country, hardly anyone bats an eye at interracial relationships. Most people do not consider racial hostility acceptable. That's why it was so shocking when Los Angeles Clippers owner Donald Sterling was caught telling his girlfriend not to bring black people to games—and why those comments led the NBA to ban Sterling for life. And yet, the killings of Michael Brown, Jordan Davis, Renisha McBride, Trayvon Martin, and so many others remind us that we are far from a prejudice-free society.

Science offers an explanation for this paradox—albeit a very uncomfortable one. An impressive body of psychological research suggests that the men who killed Brown and Martin need not have been conscious, overt racists to do what they did (though they may have been). The same goes for the crowds that flock to support the shooter each time these tragedies become public, or the birthers whose racially tinged conspiracy theories paint President Obama as a usurper. These people who voice mind-boggling opinions while swearing they're not racist at all—they make sense to science, because the paradigm for understanding prejudice has evolved. There "doesn't need to be intent, doesn't need to be desire; there could even be desire in the opposite direction," explains University of Virginia psychologist Brian Nosek, a prominent IAT researcher. "But biased results can still occur."

The IAT is the most famous demonstration of this reality, but it's just one of many similar tools. Through them, psychologists have chased prejudice back to its lair—the human brain.

We're not born with racial prejudices. We may never even have been "taught" them. Rather, explains Nosek, prejudice draws on "many of the same tools that help our minds figure out what's good and what's bad." In evolutionary terms, it's efficient to quickly classify a grizzly bear as "dangerous." The trouble comes when the brain uses similar processes to form negative views about groups of people.Comment:  For more on racism, see A Hunger to Deny Racism, White Privilege = "Willful Blindness," and Why Your Intentions Don't Matter.
