Alexander Nix, chief executive of Cambridge Analytica has a psychological model that he used for every registered voter that determined their personality that was used to create propaganda to influence their vote for president. China uses your brainwaves to do it. HERE. In 1957 author Vance Packard showed how it’s done in his book: “Hidden Persuaders” Edward Bernays wrote about it in 1928 in his book: “Propaganda”. His major coup, the one that really propelled him into fame in the late 1920s, was getting women to smoke. Women didn’t smoke in those days and he ran huge campaigns for Chesterfield. You know all the techniques—models and movie stars with cigarettes coming out of their mouths and that kind of thing. He got enormous praise for that. So he became a leading figure of the industry, and his book was the real manual. Read it free online HERE.

Why did you buy a certain brand of peanut butter? If you liked the package design you were manipulated because the design did not explain the taste of the peanut butter but was used to influence you to buy it.
Look at a box of breakfast cereal. It’s designed to get your child to tell you that’s what you should buy.
Look at an add for a car. It’s propaganda that appeals to your senses and drives your choice.

Obama did it with his “Quants”, a small group of highly educated math driven analysists who used Quantative Analysis” to target voters. HERE.
A couple of weeks before Election Day, over drinks at the Pump Room in Chicago’s Gold Coast, a safe distance away from the re-election headquarters and its press minders, Grisolano and Erik Smith first let on that there was far more happening in the Chicago campaign office than any of us covering it truly understood. Grisolano told me that the campaign literally knew every single wavering voter in the country that it needed to persuade to vote for Obama, by name, address, race, sex and income. What’s more, he hinted, the campaign had figured out how to get its television advertisements in front of them with a previously inconceivable level of knowledge and accuracy. HERE.

Unions have done it for decades. HERE. .
