Now if we accept, that such variety of "castes" of unreasonable people exists and they do not want to "grow up", then society has to be adjusted for that, i guess. Making capability groups of neuro diverse people.
Such persons would need a representative politically, to speak in there interests. Such a person would need limitations, to limit the damage they could cause.
Reasonable people would have to be protected from this non-blue-blood class, to keep them productive and isolated. Systems need to created, to rile and cool the emotions of the non-logicals to make them steerable.
There should be a science to differentiate the various types of illogical people, based upon the data collected by the big four. And steering unreasonable people should be a science too.
We should call it something cool. Something witty. Leviathancybernetics. Get it. Hobbes, the leviathan, and the art to surgically implant synthetic structures and to turn society into a prothesis god.
Now, lets talk about the negative side effects of knowing so much about society and humans. It turns you into a grandfather clock. All you hear is gears and mechanics, grinding your teeth, while all you observe your own instincts firing from the sub concious.
