The author kept trying to convince the reader there were hidden images in advertising manipulating our brains. I bought the book because I believed it was happening, but after reading the book, realized it was the author who was seeing things that didn't exist.
He had print ads in the book and pointed out the hidden images within by using a "before and after". It was like finding images in clouds. It was nonsense.
And last time I checked, the effectiveness of "subliminal advertising" (hidden messages) is still unproven.
I had to read some books like that for a college English class. It was one of the easiest A’s I earned...just write a bunch of BS!
Years ago, I was told, the military looked into subliminal messaging as a means of rapid instruction during crisis situations—i.e. the ultimate in “crash training”. Their conclusion was that “subliminal messages” were a bunch of hokum...that if a message is too quick or indistinct for the conscious mind to register it, the mind simply rejects it.
