They were a disaster. They couldn't do their assigned jobs. They got people killed and in some cases they did kill our own people. Not because they were criminals, but because they couldn't remember 'passwords' or in some cases distinguish friend from foe.
So the overall cost went beyond dollars and cents. It cost lives.
I don’t know when this was intiated, probably as an aftereffect of Project One Hundred Thousand. It is not legal to enduct anyone into the military with an IQ under 83. If yhou’re familiar with a normal distribution, one hundred is st the center. Half of the people are below 100. There are a significant number of people with an IQ below 83. They are unusable for most jobs as they can’t be trained.
BTW, the center for the normal distribution for black IQ is lower.
This doesn’t mean people with an IQ lower than 83 are bad people. It does mean you shouldn’t give them a gun and have them as the support backup you depend on.
