Just had a thought.
The prisons systems of the world, could move from imprisonment, to actual rehabilitation.
To brain-scan every entry, and then place them in designated areas, according to their wiring type. To separate the true sociopath, from the rest of the prison population.
The rest of the population will immediately settle down and then one can move toward actual and real rehabilitation of those who can be rehabilitated.
Right now, the mess is so bad, in most prisons and most countries, that the sociopaths, the true ones, are so bad, that they end up creating a permanent mess inside of those prisons.
With the brain-scanning and proper placement, the ability to reduce the prison population will be able to emerge from said mess. And that the true group who, by their wiring, cannot be rehabilitated, they can be properly contained. A sociopath can fool people, as that is part of their trick, to fit in, when they know they are different. They can't fool the brain-scan. YES, we can identify sociopathy in brain scans. Very much so.
This is is eminently doable and in many a country and case...poses no break in privacy and rights, as we are already dealing with people who are wards of the state.
Those prisoners who want to be in a safer population which is easier to work with and can be rehabilitated and every effort put into them....would VOLUNTEER for the brain scan process.
Which, incidentally, is probably a decently large percentage of the population of the given prison. Volunteers would be there, in spades, looking to get the hell out of that nightmare, for all the right reasons.
Cost? in the USA, the most expensive place in the world, for medical hardware and it's use? About $1100US, right now, per scan.
Which is an absolute pittance for the reward and change it brings.
Part of the aim of this, is to show that it will work.
The end result is to take those successes...and turn to testing for sociopathic wiring, to testing for that..in people in politics, power, finance and military, and so on.
Hell, I'd actually have it on my resume:
"Tested to be nil for sociopathic wiring, by accredited agency so and so". Another form of being bonded.
