A better turn, would be for the avatar we are attempting to convey information to, to lack sufficient experience or educational background to comprehend even the descriptions, and further, to suspect being influenced by daedric princes, like sheogorath and hermaeus mora.
(I could easily see a knockdown drag out between those two should I be at the wheel, fighting over who gets to play with the addled engineer. There is a fine line between brilliance and madness. And complex knowledge often has maddening effects, when natural limitations are lifted, such as through magical intervention. The afore mentioned CE trinkets I mentioned would let you build a high performance tesla roadster, for instance, that completely violates the laws of conservation of energy, and the second law of thermodynamics. Madness in a metal box. If it makes enough shock to harm you, it makes enough shock to power the car in place of the battery array, and if it makes things cold, without offsetting heat someplace else, it is destroying entropic energy. Ever wondered what a superconductive magentic drive in an electric car with an inexhaustible power supply is like to drive? Given those two curious items, an old wagon, a kiln, some copper wire, and lots of free time, I could very well show you.
efficiency wouldn't matter a whole lot. The power plant is inexhaustible, and heat can be destroyed. The pandora's box that combination offers is maddening. Likwise with feather and burden enchantments. Oh, the fun I could have with those...)
The point is that those concepts would be radically alien to our avatar, and thus would appear as unintelligable hallucenations. Look at a complex wiring diagram sometime. Does it make sense to you? Likewise, the subject of your compulsions would not comprehend the meanings behind what he is drawing, and thus could not convey such meaning to artisans. Education does not make someone smarter, but it empowers a smart person to understand and do more. A LA major would probably be good with artistic things and with languages, but wouldn't know the first thing about designing resonant tank circuits, what a youngs modulous is, etc.
The avatar isn't dumb, but lacks the understanding to comprehend the compulsion. Receiving concistent and regular compulsions of such a nature may well make them question their sanity.
