We humans, being the product of a long evolutionary process, really have three brains. And, as the Bush psy-ops folks know, politicians who win campaigns do so because they speak to all three of those brains.
First there's the most primitive of our brains, sometimes referred to as the "reptilian brain" because we share it in common with reptiles like alligators and komodo dragons. The reptile brain has a singular focus: survival. It doesn't think in abstract terms, and doesn't feel complex emotions. Instead, it's responsible for fight-or-flight, hunger and fear, attack or run. It's also non-verbal - you can stimulate it with the right words, but it operates purely at the level of visceral stimulus-response.
The second brain is one we share with the animals that came along after reptiles - mammals. The mammalian brain - sometimes referred to as the Limbic Brain because it extends around and off of the reptilian brain in a dog-leg shape that resembles a limb - handles complex emotions like love, indignation, compassion, envy, and hope. Anybody who's worked with animals or had a pet knows that mammals share these emotions with humans, because we share this brain. While a snake can't feel shame or enthusiasm, it's completely natural for a dog or cat. And, like the reptile brain, the mammalian brain can also be stimulated indirectly by words, and is also non-verbal. It expresses itself exclusively in the form of feelings, although these are more often felt in the heart than the gut.
The third brain - the neocortex ("new" cortex) - is something we share with the higher apes, although ours is a bit more sophisticated. Resting over the limbic brain (which is, in turn, atop the reptilian brain), our neocortex is where we process abstract thought, words and symbols, logic and time.
When Dick Cheney recently took John Kerry's comment about sensitivity in the war on terror out of context and spun it for his audiences, he was performing a psychologically masterful bit manipulation of all three brains.
Only ridicule with a subtext of fear has this power. (snip)
