Reiteration over and over again of the same message with different codes makes many educational programs boring, in spite of the adoption of audio-visual methods of communication. You, in India, know how boring Doordarshan can be, the once-monopolist TV channel of the Government. It is boring because people perceive that the Government, through television, wants to impose something upon you, and does it bluntly. But even when persuasion is done in a more delicate, intelligent and subtle way, you still will not like it.
Why does redundancy, at times, work?
If redundancy is boring, why does it, at times, work? Why are ads attractive? Well! Ads are ads if they are attractive. If they are not attractive, they are not ads. The typical style of ads is that of an effort to seduce. Seduction is based on the implication of basic human instincts, i.e. sex and power. Ads will imply that, by buying that product, you either get some kind of erotic satisfaction or some kind of power status. Both these promises sound attractive. The poster, or the video, etc., make the viewer pre-taste that eroticism that the buyer could enjoy once he becomes the owner of that item on sale. Or pre-taste the social status that the buyer will obtain with the acquisition of that status symbol. Letting the person imagine the pleasure he would get by complying with our suggestions: that’s how we construct a seductive ad.
