In younger years I wished I could pass out on my English Lit text and awaken primed and ready for that days exam. I have since seen parlor trick displays of memory feats.
A charlatain in denial will ask a person to 'pick a page' from some 'classic' novel. Then, 'pick a paragraph' followed by, 'pick a number'. Audience members were awestruck as he correctly informed them that the 8th word in the 3rd to last paragraph was 'chapfallen'.
Or another might ask 137 audience members their first names. Over the coures of an hour long sales pitch all 137 would be recaled. With one "really tough" one that he knew he was gonna have a hard time with.
Kubrik showed the eyes peeled open in A Clockwork Orange. Subliminal ads in theaters. Sci Fi film is loaded with these 'plug and learn technologies' for humans.
So what is real? Where are we now with this? Are there any published studies? Disclosed technologies? Underground labs?
