it’s not the size of our brains or the number of neurons, it’s about the patterns of connectivity.
our brain specializes and localizes. As Dr. Gazzaniga puts it, “Small local circuits, made of an interconnected group of neurons, are created to perform specific processing jobs and become automatic.” This is an important advance in our efforts to understand the mind.
Emergence, Gazzaniga goes on, is how to understand the brain. Sub-atomic particles, atoms, molecules, cells, neurons, modules, the mind, and a collection of minds (a society) are all different levels of organization, with their own laws that cannot necessarily be predicted from the properties of the level below.
The unified mind we feel present emerges from the thousands of lower-level processes operating in parallel. Most of it is so automatic that we have no idea it’s going on. (Not only does the mind work bottom-up but top down processes also influence it. In other words, what you think influences what you see and hear.)
This left-brain module is what we use to explain causality, seeking it for its own sake. The Interpreter, like all of our mental modules, is a wonderful adaption that’s led us to understand and explain causality and the world around us, to our great advantage, but as any good student of social psychology knows, we’ll simply make up a plausible story if we have nothing solid to go on — leading to a narrative fallacy.
