Give me a little credit for knowing my own mind, please. I meant exactly what I wrote.
Edit: I mean, yes, some people do think they came up with the idea that was just suggested to them. Stage magicians have used suggestion tricks for years. But part of my point is that billboards that simply remind you that a product exist, and your own preexisting desires then make you want to buy it, are the form of advertising I am least annoyed by. Even people susceptible to ads had some kind of preexisting desire for the product (I really don't like those curtains, I know we only bought them two months ago but I'm having buyer's remorse, I want something else, oh look, curtains on sale!) or else the ad wouldn't work. I mean, if I know I don't have psoriasis then I won't care about psoriasis medication ads in the slightest. But if I suspect I have psoriasis (maybe I do have it, or maybe I'm a hypochondriac) then the ads will actually have a chance of influencing me.
Thing is, as far as I myself am concerned, I'm a pretty content guy. What I want is more good books to read, more good open-source software to be created, and to be able to enjoy time with my wife and kids. Almost none of which are desires that will make me susceptible to most ads. (Though if the ad was "Hey, Lois Bujold has a new book series out!" then yes, I'd be susceptible to that ad. But again, pre-existing desire: Bujold has only written two books out of her entire oeuvre that I've disliked. A much higher like-to-dislike ratio than most authors).
