It’s not enough to have one hook anymore,” Jay Brown, the president of Roc Nation, and Dean’s manager, told me recently. “You’ve got to have a hook in the intro, a hook in the pre-chorus, a hook in the chorus, and a hook in the bridge.”
The reason, he explained, is that “people on average give a song seven seconds on the radio before they change the channel, and you got to hook them.
The deep and beautiful trick of the brain is more interesting: it possesses multiple, overlapping ways of dealing with the world. It is a machine built of conflicting parts. It is a representative democracy that functions by competition among parties who all believe they know the right way to solve the problem.
As a result, we can get mad at ourselves, argue with ourselves, curse at ourselves and contract with ourselves. We can feel conflicted. These sorts of neural battles lie behind marital infidelity, relapses into addiction, cheating on diets, breaking of New Year’s resolutions—all situations in which some parts of a person want one thing and other parts another.
These are things which modern machines simply do not do. Your car cannot be conflicted about which way to turn: it has one steering wheel commanded by only one driver, and it follows directions without complaint. Brains, on the other hand, can be of two minds, and often many more. We don’t know whether to turn toward the cake or away from it, because there are several sets of hands on the steering wheel of behavior.
