The mental trap or "The Box" as it is often called came from "experts" and their followers on such subjects like religion, science, economics and foreign affairs.
These mental boxes are created by know-it-all authorities who probably do a great deal of debunking of other people's creative ideas. An outstanding example of this is the criticism levelled at inventor, Thane Heins, with regards to his offbeat electrical motor.
"Conventional wisdom" and "expert opinion" often trys mold us into sheeplike victims of fate.
If we followed these "shamans", we'd probably still be hurling rocks at each other in caves.
