For example, take the book "The Game" which purports that, using a swathe of bastardized NLP techniques and cocky attitude, any man can pick up any woman at any time. "The Game" does not teach people to become modern-day lotharios, it tells men to become walking sandwich boards to elicit emotional responses from others to achieve their goals - it teaches them to become walking bullshit-spouting advertisements. An advertisement tells you nothing about the product; it only claims certain abstract positions and forces you to react on an "emotional" level. If you want someone to buy your product or use your service, you must make them "feel good" about it. The world of modern-day advertising aims at just that. I can promise you abstracts, therefore I can promise the world. It is hard to refute an advertisement, since it doesn't set itself up to be challenged. Game rules, indeterminacies and double binds make sure of it.
Hey, I'm not one to make a case against it - if the shoe fits, wear it!
