Science, I love ya.
I am of the opinion, and have been for some time, that the mindset of people who are politically, socially, and/or religiously conservative is the product of some kind of mental abnormality. It’s a position I have expressed often on this blog, including posts here, here, and here.
I hold that view because right-wing thinking routinely ignores facts and logic. Conservatives are, by nature, remarkably closed-minded. Great numbers of them live their lives hating on and fearing various forces they perceive are out to get them, take from them, or diminish them. For psychological reasons, they seem to need an enemy they can blame for whatever upsets them.
Behavior like that isn’t normal or healthy. The negativity, the anger, the bunker mentality, the resistance to change — it’s always led me to suspect that something isn’t right up in the belfry.
Well, now there is new science that backs me up. Researchers at Northwestern University say they have identified a link between brain damage and religious fundamentalism.
According to their findings, damage to the prefrontal cortex — the “executive” region of the brain, which governs higher mental functions such as decision-making — can diminish “cognitive flexibility,” making the victim less open-minded, less accepting of new ideas, and correspondingly more extreme in religious beliefs.
Specifically, damage to the ventromedial prefrontal cortex has the reported effects.
The Northwestern study compared two groups of Vietnam War veterans. One group had suffered damage to the prefrontal cortex, the other had not. The subjects were tested to assess the traits of cognitive flexibility and openness and to determine religious/political beliefs.
The subjects with trauma to the ventromedial prefrontal cortex scored lower on cognitive flexibility and openness and higher on conservatism and religious fundamentalism. The subjects who had suffered no trauma scored the opposite.
Why? Because of the difference between empirical thinking and religious thinking.
Empirical beliefs (science, learning by observation, etc.) are based on real facts in the real world. Empirical thinking also can accommodate change if new empirical evidence warrants.
Religious beliefs, on the other hand, are the opposite. Fundamentalism and conservatism are fixed and rigid. They discourage progressive thinking. They reject scientific explanations and new evidence. Anything that questions their beliefs and traditions is seen as a threat to group stability and may be opposed aggressively.
Cognitive flexibility, by the way, simply means flexible thinking. This trait allows the brain to switch lines of thought quickly, to consider new evidence, and to adjust beliefs and behavior accordingly. It’s a key survival skill in organisms large and small.
The Northwestern study noted that other factors can influence political and religious convictions, including social environment and innate personality traits. But they emphasized the need to understand the mechanics of how religion works in people because it is so influential in virtually every society.
To summarize:
(1) The trait of cognitive flexibility provides a mental edge in dealing rationally with the world and adapting to change.
(2) Researchers have found evidence that brain damage can reduce cognitive flexibility and lead to an increase in conservative/fundamentalist thinking.
Empirical thinking scores another point for empirical thinking.
Maybe damage to the prefrontal cortex, or faulty wiring in the brain from birth, helps explain the loony behavior of the Republicans in recent times. Maybe it helps explain the bizarre and creepy MAGA crowds that assemble for Trump rallies.
And maybe it sheds light on why an appalling number of people voted for Trump and still support him, despite the empirical evidence that he is a corrupt, amoral con man who is owned by Russian gangsters and should have been ejected from office long ago on grounds of collusion, negligence, malfeasance, and the commission of high crimes and misdemeanors.
But I digress.
