But the thing is, we treat racism in this country like it’s a style that America went through. Like flared legs and lava lamps. Oh, that crazy thing we did. We were hanging black people. We treat it like a fad instead of a disease that eradicates millions of people. You’ve got to get it at a lab, and study it, and see its origins, and see what it’s immune to and what breaks it down.

Educated people, of course, know that perception, cognition, language and emotion are rooted in the brain. But it is still tempting to think of the brain as it was shown in old educational cartoons, as a control panel with gauges and levers operated by a user – the self, the soul, the ghost in the machine, the person, the “me.” But cognitive neuroscience is showing that the self, too, is just another network of brain systems.

One of the most dramatic demonstrations of the illusion of the unified self comes from the neuroscientists Michael Gazzaniga and Roger Sperry, who showed that when surgeons cut the corpus callosum joining the cerebral hemispheres, they literally cut the self in two, and each hemisphere can exercise free will without the other one’s advice or consent. Even more disconcertingly, the left hemisphere constantly weaves a coherent but false account of the behavior chosen without its knowledge by the right. For example, if an experimenter flashes the command “WALK” to the right hemisphere (by keeping it in the part of the visual field that only the right hemisphere can see), the person will comply with the request and begin to walk out of the room. But when the person (specifically, the person’s left hemisphere) is asked why he just got up, he will say, in all sincerity, “To get a Coke”—rather than “I don’t really know” or “The urge just came over me” or “You’ve been testing me for years since I had the surgery, and sometimes you get me to do things but I don’t know exactly what you asked me to do.” Similarly, if the patient’s left hemisphere is shown a chicken and his right hemisphere is shown a snowfall, and both hemispheres have to select a picture that goes with what they see (each using a different hand), the left hemisphere picks a claw (correctly) and the right picks a shovel (also correctly). But when the left hemisphere is asked why the whole person made those choices, it blithely says, “Oh, that’s simple. The chicken claw goes with the chicken, and you need a shovel to clean out the chicken shed.”

The spooky part is that we have no reason to think that the baloney-generator in the patient’s left hemisphere is behaving any differently from ours as we make sense of the inclinations emerging from the rest of our brains.

Jeff Bezos says, ‘Your margin is my opportunity.’ That’s probably what Lyft and Uber were saying to each other as they slashed their commissions to 0. How do you beat a company that doesn’t need to make money? The 8 hours you need to sleep each night, are my opportunity. The time you spend with your family and friends, is my opportunity. If you’re not maxed out, if there’s still a shred of humanity left in you, then you’re just leaving your lunch on the table.
