In Blink, Gladwell describes our "adaptive unconscious" as a "giant computer that quickly and quietly processes a lot of the data we need in order to keep functioning as human beings." Could he possibly get any vaguer? That sentence could easily have been written 50 years ago, back when Freud was still cool and computers were the size of refrigerators. What Gladwell never mentions is that the "big unconscious computer in our brain" is actually composed of many different brain regions, which are only loosely interconnected. Our "blink" decisions aren’t simply a by-product of some invisible mainframe in the head. Rather, they emerge from a continuous dialogue between our many different neural parts, some of which we are consciously aware of, and some which we aren’t.
