I've seen the Derren Brown video[1] mentioned at the beginning of this article. But I'm wondering whether it is "real". For example, there must be a cameraman in the car on the trip, and he deliberately films the supposed subliminal cues. Are we expected to believe that the people in the car did not notice this? And there are other carefully positioned cameramen on the route the car takes. Etc. I think it likely that the video is a setup -- or at least a very poorly designed experiment.
I realize that this article is really about Whole Foods and their marketing strategy. Still, the article spends three paragraphs talking about Brown's "trick", implying that it is solid evidence of an surprising and significant phenomenon.
And now the question: What you do think? Also, does anyone have more concrete evidence on trustworthiness of the Brown video?
