The general public is denied access to power knowledge, not only via social conditioning, but as a result of actually making such knowledge permanently unavailable.
But as it could turn out, unless the power potentials among those members were de-energized in some fundamental way, then merely denying access to power could become quite a contest and burden. In other words, the powerless must somehow be made to FEEL powerless in some kind of way that seems logical and authentic to them, and in a way that will neutralize, and/or de- energize, any feelings of being powerful.
Some examples of this might include: being born into a naturally powerless class; being socially conditioned to think of oneself as stupid and illiterate; not having enough education; not being too intelligent; not being acceptable to one’s betters; being taught to respect the powerful; and so forth.
Above all, the powerless must not be permitted to have any idea of what can transcend human-designed power structures — those societal artifices mistaken as power itself.
In this case, it is logical that the powerful must have control, authority, and influence not only over the intelligence of the others, but over how misunderstandings about intelligence should be engineered.
In this sense, the engineered misunderstandings would act like prophylactic preventives against the emergence of evocative understandings that might trigger and activate empowerment and power.
