We can transplant hearts, kidneys, lungs, livers, faces, bone, and uteri. We can implant artificial joints, bladders, heart assist devices, and an increasing number of stem cells and other tissues. We can use dialysis machines to substitute for failed kidneys, use breathing assist ventilators when our cervical spinal cord is interrupted, and an increasing number of other external machines to substitute for the loss of one function or another.
But when brains fail, a transplant would not serve the purpose of restoring the person. Brain implants of a tissue or electromagnetic nature can help compensate for limited damage in a few cases. But for most damaged and ageing brains — in an ageing western world — there is no going back. This accelerating loss of brain power should cause us to want to understand this 3 pound miracle much more thoroughly than we do — because it is the thing that creates the world we live in.
The brain exhibits a number of curiosities. For example, the brain is capable of recognizing an image in as little as 13 milli-seconds. That is rather fast, and strains current explanations for how the brain forms images. Our brains also have built-in number sensors, which can quickly fit the number of seen objects into categories of size — for example, do you have more than 20 items in your shopping cart as you approach the express lane?
Our “likes and dislikes” are guided by subliminal cues that we will never understand, many of them of an olfactory nature. When something is rotten in Denmark, we may not understand why, but we can be certain of the fact inside ourselves.
And then there is the question of why the brains of some human population groups perform consistently better than the brains of other human population groups. We are assured by our politically correct overlords that all humans are the equal, the same, in terms of potential brainpower, and that it is only cultures or environments that prevent some groups from achieving as much as others.
But we know that different populations groups have different genetic distributions. And we understand that genes affect every aspect of brain anatomy and brain functioning. So logically, it makes sense — all political correctness aside — for different breeding populations to differ in measures of brain function, at least on a grouped statistical level.
Here is a short literature survey from Kevin McGrew, looking at studies that studied the relationships between brain efficiency, connectivity, intelligence, and executive function. And here is a recent study looking at how brain cell metabolism affects the ability of brain cells to signal each other.
We clearly understand how genes affect cell metabolism. It makes perfect sense to assume that brain cells with cleaner and more efficient metabolism will function more efficiently at their prime purpose — signalling. Or is that line of thinking racist, sexist, homophobic, islamophobic, or otherwise politically incorrect?
If we look at average IQ for nations, and correlate those with national wealth, we find a very close correlation.
Of course we understand that other factors are involved in creating national wealth, including economic freedom. Under President Obama, the US is losing ground on that front.
It is important to understand our brains: How to empower them in the young, how to develop them in youth and adulthood, and how to preserve them well into old age.
Despite the siren songs of collectivists and the politically correct, we are pretty much on our own — and getting more-so as governments grow more nepotistic and corrupt. Even in the face of a loss of economic and personal freedoms, Dangerous Children are best equipped for dealing with the changes.
It is never too late for a dangerous childhood.
