"The Engineering of Consent" is an essay by Edward Bernays first published in 1947. He defines "engineering consent" as the art of manipulating people. It maintained that entire populations, which were undisciplined or lacking in intellectual or definite moral principles, were vulnerable to unconscious influence and thus susceptible to want things that they do not need. This was achieved by linking those products and ideas to their unconscious desires. Ernest Dichter, who is widely considered to be the "father of motivational research," referred to this as "the secret-self of the American consumer. In other words, consumer psychologists have already made the choice for people before they buy a certain product. This is achieved by manipulating desires on an unconscious level. The central idea behind the engineering of consent is that the public or people should not be aware of the manipulation taking place.
Edward L. Bernays was an Austrian-American pioneer in the field of public relations and propaganda, referred to in his obituary as "the father of public relations".
A bit dated considering the advent of the internet plays a major role now in the topics this book presents, and which I'm sure has "changed the game" in a major way, but still a very interesting volume and I think mostly still applicable today.
As the writer states: Books on public relations usually place undue emphasis on the minutiae of public relations. This book uses a different approach. It considers what it is, what relation it has to society, how it approaches a problem, and how that approach is made.
This is a wonderful book about the practical methods to make people believe the non-sense you want them to. It includes many of the important ideas in great advertising including the idea that people should not realize it's advertising, but think it's unbiassed news. Many of these techniques are innovations of Bernays himself, a nephew of Freud, and a long-standing fixture on Madison Avenue.
