Hmmm, I was around in the 70's, I remember carter's high interest rates, gas lines and 55mph speed limit on interstates, but no mass hypnosis. What did I miss?
You missed the experiments with NLP to do with commercials and mass hyponosis style selling.
Not as much as you might think. Neurolinguistic programming was a trendy sort of communications fad promulgated mostly by a couple of guys from California(naturally) in a pair of books called "The Structure Of Magic." They had concocted a theory of persuasive communication based on the application of another academic fad, Ericksonian hypnosis, and attempting to capitalize on the theory that the two cerebral hemispheres handled information differently.
Like global warming and a few other shell games, these were heavy on speculation("Theory") but scarce on data. Lots of anecdotal and illustrative stuff but as so often has been the case with these "breakthroughs" it just didn't turn out to be magic after all.
Within a few years the NLP "founders," Bandler and Grinder, came to be known as "Bandit and Swindler"-- but not before they had hosted a plethora of high-priced workshops and weekend dog & pony shows around the country.
I was studying hypnosis in depth myself during these years and was very familiar with their stuff. There were some good observations they made about how people communicated, but nothing a good salesman didn't already know implicitly, and certainly nothing to be afraid of.
Bammy has charisma, which is altogether a different thing.
