I remember hearing a case study of Philips (as far as I can recall!) many years back in a conference. The study was about how people say a particular thing when asked for opinion but can do entirely different things. In this case, it was about color preferences of a portable music system. The potential users said that they prefer red but actually picked up a black one.
Does anyone recall this story or was it someone's figment of imagination? Any clues to this story would be helpful.
