In the prior section, How We Understand Anything, I presented some generalizations about human understanding that are based largely on studies in cognitive psychology. Here I will present some additional generalizations that you may find more difficult to accept. The findings in this section come largely from research in neuroscience and evolutionary anthropology.
Since the advent of magnetic resonance imaging, MRI, researchers have developed ways to directly observe limited aspects of the brain's functioning. For example, it is now possible to tell which brain areas are involved in responding to certain events or in solving certain problems. Although this knowledge is still rather low-resolution, it can be combined with other techniques, new and old, to form conclusions about how the brain is organized. (See Neuroimaging and Pain Measurement for more about these techniques.) A general finding is that our brains shouldn't be thought of as large reservoirs of "smart" tissue, but instead as a collection of many specialized modules that solve small problems and other modules that integrate the products of the detail modules so that they are useful for us. This is modern neuroscience.
Alongside neuroscience, evolutionary anthropology and related fields have used neuroscientific findings and many other techniques to formulate generalizations about how we think: how we perceive, how we pay attention, how we evaluate, how we remember. Anthropology is fundamentally a science that looks for human nature. It looks for patterns of behavior that are present among many human communities in many environments. The word "evolution" makes some uncomfortable, either because of ideological positions or because "the past is just a goodbye." (Crosby, Stills, Nash and Young, "Teach Your Children.") If this fits you, think "adaptive" instead of evolutionary.
Neuroscience and evolutionary anthropology pursue overlapping knowledge, although in different ways. Neuroscience looks at our physiology and "wiring," while evolutionary anthropology begins with questions about human behavior and applies a large number of methods to inquire into the how, what, and why. There is cross-talk between the two disciplines.
In this section you'll encounter some assertions about human nature that may surprise or even offend you. They are all based on scientific enquiry. This doesn't guarantee that they're correct or will stand in the advance of knowledge, but they do provide a distinctly different understanding of us than traditional thinking has. Keep an open mind, let the ideas simmer, and think about how they might affect our views about pain and the pain sufferer.
Neuroscience and evolutionary psychology inform us that we process information and make decisions much differently than we are accustomed to believe. Our belief that we consciously control our own behavior is challenged by the finding that we begin to develop action plans unconsciously as much as ten seconds before we act. The impression that we perceive events in real time is an illusion brought about by complex wiring in our brains. We are perfectly capable of ignoring anything we choose to ignore. We're even able to intentionally forget certain things.
