Re: Ideology: Humanity’s Weakest Link
We are taught, both by our educational institutions and through social osmosis, that we are creatures who can find truth by a dispassionate search of reality for that truth. We learn that we have the ability through “a dispassionate mind that makes decisions by weighing the evidence and reasoning to the most valid conclusions” to reach conclusions about truth. “This bears no relation to how the mind and brain works.”
A study of cognitive science, psychology, and other domains of knowledge convince me that we have a partisan brain. That is too say that we generally exhibit a blind, prejudiced, and unreasoning allegiance to a set of abstract ideas when that set of ideas is also held by other members of the society. We tend to be unduly influenced by group think. We are unduly influenced by a group psychology.
Drew Westen, in his book “The Political Brain”, speaks of the study of the brains of “fifteen committed Democrats and fifteen confirmed Republicans”.
The brains of these partisans were scanned for activity while they read a series of slides. “Our goal was to present them with reasoning tasks that would lead a “dispassionate” observer to an obvious logical conclusion, but would be in direct conflict with the conclusion a partisan Democrat or Republican would want to reach about his party’s candidate.”
The results of this testing showed that “when partisans face threatening information, not only are they likely to “reason” to emotionally biased conclusions, but we can trace their neural footprints as they do it…When confronted with potentially troubling political information, a network of neurons becomes active that produces distress…The brain registers the conflict between data and desire and begins the search for ways to turn off the spigot of unpleasant emotion.”
There was further interesting results from the test. The brain not only shut down distress but very quickly “the neural circuits charged with regulation of emotional state seemed to recruit beliefs that eliminated the distress and conflict partisans had experienced when confronted unpleasant realities. And this all seemed to happen with little involvement of the neural circuits normally involved in reasoning.”
“The partisan brain did not seem satisfied with just feeling better. It worked overtime to feel good, activating circuits that give partisans a jolt of positive reinforcement for their biased reasoning.”
