The conundrum of the twenty-first (century) is that with the best intentions of color blindness, and laws passed in this spirit, we still carry instincts and reactions inherited from our environments and embedded in our being below the level of conscious decision. There is a color line in our heads, and while we could see its effects we couldn’t name it until now. But john Powell is also steeped in a new science of “implicit bias,” which gives us a way, finally, even to address this head on. It reveals a challenge that is human in nature, though it can be supported and hastened by policies to create new experiences, which over time create new instincts and lay chemical and physical pathways. This is a helpfully unromantic way to think about what we mean when we aspire, longingly, to a lasting change of heart. And john Powell and others are bringing training methodologies based on the new science to city governments and police forces and schools. What we’re finding now in the last 30 years is that much of the work, in terms of our cognitive and emotional response to the world, happens at the unconscious level.
